Tim,
what is your tube brand name?
Tyre /tube sizes? 7.00-6?

I keep the tyre pressure between 28-30 psi. No
problems with the tyre after 250hours 464 cycles.
Only disadvantage with the higher pressure is one
has to be more diligent on controlling the
aircraft path when landing on hard pavement
runways. I did not use the original Europa tyre
but use the Mccready? Air tire, narrower and
stronger.

Raimo,
Not sure what the size was. Next time I go out to the aircraft I will have a look. It was a McCreary from:

Graham,
Yes, I think that is why Kim Prout recommended the narrower McCreary tire and higher pressure
when I flew with him many years ago now.

Dear Jim
Read careful my post: I like to use pressure 2,0 - 2,2 bars. 2,1 bar = 30,45 PSI. So we land with same pressures. Pressure - low or high - is not a reason.
What is your tube brand name?
What is your tube and tyre size?
Until I will get a reason and solution I am going to do same as Paul is doing: changeing regularly tube. Makes me sense to change it every year (= in my case every 50 hrs /about 50 - 100 landings. I never can do it in 30 minutes but so what. Tube is very cheap. For example yeasterday I spent 6 hrs fighting with that problem with my wife and that newspaperman. That is 18 hrs + all the extra fees + 400 km driving car. That must be same as buying let us say 100 pcs of tubes.
BTW also I use masses of baby bottom talcum. That delicate scent is a bit embarrassing...

All monowheel drivers
Following this thread today... I have a few commits to throw to the forum...I notice that Europa requires very low tire pressure in their manual...
I also noticed today that quiet a few monowheel drivers are having flat's....I suspect that with the low air pressure, when you land the sidewals are flexing due to low air pressure...this is probably "pinching the inner tube" and then the tire goes flat....
I have always kept 32 PSI in the tire. IN 10 years, and two tires and tubes, I have never had a flat....Yes I know I have been blessed by the good luck god..
Thank about it with 32 P S In the tube the sidewalls are not flexing......Just my thought's on this matter....

Following this thread today... I have a few commits to throw to the forum...I notice that Europa requires very low tire pressure in their manual....
I also noticed today that quiet a few monowheel drivers are having flat's....I suspect that with the low air pressure, when you land the sidewals are flexing due to low air pressure...this is probably "pinching the inner tube" and then the tire goes flat....
I have always kept 32 PSI in the tire. IN 10 years, and two tires and tubes, I have never had a flat....Yes I know I have been blessed by the good luck god..
Thank about it with 32 P S In the tube the sidewalls are not flexing......Just my thought's on this matter....

<?xml:namespace prefix="v" /><?xml:namespace prefix="o" /><![endif]--> To all, and congrats to Raimo Toivio
When preparation, proficiency and proper procedures meet a potentially catastrophic chain of events, the chain is broken and the aircraft, pilot and passengers all have a story to tell rather than being an accident statistic.
Your thorough planning for tire changes in the field, spares, and most importantly a lovely and supportive wife makes the event a nuisance tire change out in the field, so I am hoping you bought your wife a great dinner and told her how much you appreciate her.
As for tires and tubes, from what I can report from the US mono pilots that have shared their experiences with me here goes:
Original Classic Equipment was an industrial 8 inch tire and tube. Cheap, strong but rather thin with squishy sides. The clearances were minimal from the frame and cockpit module and during landing the brake caliper on a flat tire tore it up pretty quick. About 2000 most guys started going with the 7 inch McCreary as a replacement around here. It is narrower and of course a little lower. The original tube was a bit thin but cheap at $35 for a lawn tire tube.
Replacement Tires:
The McCreary 7 inch six ply seems to work very well with very long life. This tire has more clearance from the frame, the wheel well, and its six ply sides is very stiff. It is available through Europa or Aircraft Spruce (PN 06-09600):
for about $130 US and is worth every penny.
Replacement Tubes: Europa tubes are now made by McCreary and are for a 7-8 inch tire. They are very well built, and have the exact 90 degree bend and placement of the valve stem for the mono's wheel. They are about $130 each, and again worth every penny. It is my experience they are changed only on puncture not wear.
Most taxi failures need a serious autopsy of the tube. I have found with new clients that they pinch the tube or cut the stem. Once the tire goes flat, it gets cut by the brake caliper. We have gone to a full proof method here in the shop. First we inspect the wheel for any burrs or sharp edges on the rim and especially on the valve stem. We smooth these out if present. Then thoroughly clean and dry the wheel. We cut card stock that fits the recess machined into the wheel and glue it in place with super glue dabs on one side only. Then show the client how the wheels go together and to watch for the white paper in the wheel half split with an inspection mirror to make sure all goes together easily. Then the tube is lightly powdered , inserted into the tire, aligned with the stem aligned with the dot (not always present) and slide the wheel into the tire. Carefully align the tube stem and ensure the tube is not twisted. Now carefully install the other wheel half and gently push the two halves together. Insert bolts and pull up evenly. The tire is ready to inflate.
A suitable lubricant for tire to wheel during installation is not axel grease according to the FAA maintenance folks. There is no reason for lube on a well maintained rim free of dirt, corrosion etc. If the tire will not go on the rim, use a proper lube such as Freylube or a mixture of dish soap and water with no more than 10% mineral oil. Allow the solution to dry before putting the tire in use. Petroleum lubricants between the tire and rim may cause the tire to rotate on hard braking or run-up (and the tire will rotate on the rim with a 914 at full blast with an Airmaster Prop), causing tube stem or tube failure. Learn from my mistake. Read Michelin's guide to tire installation: http://www.airmichelin.com/uploadedFiles/MichelinAirDev/StandardContent/Resource/certification_level_2.pdf
Great job Raimo,

Hi! All
Just for information and safety knowledge I can declare that my trike has
landed with a flat nose wheel without anything startling . I had been aware
of the likelihood prior to landing .
Regards
To all

Raimo; sorry for the delay... The tire is a Goodyear 700X6 6Ply rated. This tire has about 400 hours on it. The tread wear is showing about half the tread is gone...

Dear Jim
Read careful my post: I like to use pressure 2,0 - 2,2 bars. 2,1 bar = 30,45 PSI. So we land with same pressures. Pressure - low or high - is not a reason.
What is your tube brand name?
What is your tube and tyre size?
Until I will get a reason and solution I am going to do same as Paul is doing: changeing regularly tube. Makes me sense to change it every year (= in my case every 50 hrs /about 50 - 100 landings. I never can do it in 30 minutes but so what. Tube is very cheap. For example yeasterday I spent 6 hrs fighting with that problem with my wife and that newspaperman. That is 18 hrs + all the extra fees + 400 km driving car. That must be same as buying let us say 100 pcs of tubes.
BTW also I use masses of baby bottom talcum. That delicate scent is a bit embarrassing...

Following this thread today... I have a few commits to throw to the forum...I notice that Europa requires very low tire pressure in their manual...
I also noticed today that quiet a few monowheel drivers are having flat's....I suspect that with the low air pressure, when you land the sidewals are flexing due to low air pressure...this is probably "pinching the inner tube" and then the tire goes flat....
I have always kept 32 PSI in the tire. IN 10 years, and two tires and tubes, I have never had a flat....Yes I know I have been blessed by the good luck god..
Thank about it with 32 P S In the tube the sidewalls are not flexing......Just my thought's on this matter....

Hi Jim,
have you any idea what is your tube brand name? I think that (the tube) could be something between happy landing and a possible disaster or pain at least.
***
To prevent future tube-related accidents my plan is to go as follows:
1) change a very best available tube (www.desser.com , McCreary ?)
2) change it for new one regularly ie. once a year to prevent it is ageing.
3) consider seriously what is the best size for it (must be same as tyre and that is in my case 7.00-6)
4) install it with extreme care and baby bottom talcum
5) keep a good tyre pressure ie. 2,0 – 2,2 bar
6) fill the tyre with some well known pre puncture liquid (www.slime.com ?)
7) have a low tube pressure on-flight control system (www.conrad.fr ,thanks Alain)
 carry always in a plane a spare tube (with a lifting block)

Dear Jim
Read careful my post: I like to use pressure 2,0 - 2,2 bars. 2,1 bar = 30,45 PSI. So we land with same pressures. Pressure - low or high - is not a reason.
What is your tube brand name?
What is your tube and tyre size?
Until I will get a reason and solution I am going to do same as Paul is doing: changeing regularly tube. Makes me sense to change it every year (= in my case every 50 hrs /about 50 - 100 landings. I never can do it in 30 minutes but so what. Tube is very cheap. For example yeasterday I spent 6 hrs fighting with that problem with my wife and that newspaperman. That is 18 hrs + all the extra fees + 400 km driving car. That must be same as buying let us say 100 pcs of tubes.
BTW also I use masses of baby bottom talcum. That delicate scent is a bit embarrassing...

All monowheel drivers
Following this thread today... I have a few commits to throw to the forum...I notice that Europa requires very low tire pressure in their manual....
I also noticed today that quiet a few monowheel drivers are having flat's....I suspect that with the low air pressure, when you land the sidewals are flexing due to low air pressure...this is probably "pinching the inner tube" and then the tire goes flat....
I have always kept 32 PSI in the tire. IN 10 years, and two tires and tubes, I have never had a flat....Yes I know I have been blessed by the good luck god..
Thank about it with 32 P S In the tube the sidewalls are not flexing......Just my thought's on this matter....

I purchased the tube whenI purchased the tire from Dresser.....Sorry I do not know the name of the tube...Your outlined plan seems to be well thought out.

Hi Jim,
have you any idea what is your tube brand name? I think that (the tube) could be something between happy landing and a possible disaster or pain at least.
***
To prevent future tube-related accidents my plan is to go as follows:
1) change a very best available tube (www.desser.com , McCreary ?)
2) change it for new one regularly ie. once a year to prevent it is ageing.
3) consider seriously what is the best size for it (must be same as tyre and that is in my case 7.00-6)
4) install it with extreme care and baby bottom talcum
5) keep a good tyre pressure ie. 2,0 – 2,2 bar
6) fill the tyre with some well known pre puncture liquid (www.slime.com ?)
7) have a low tube pressure on-flight control system (www.conrad.fr ,thanks Alain)
carry always in a plane a spare tube (with a lifting block)

Raimo; sorry for the delay... The tire is a Goodyear 700X6 6Ply rated. This tire has about 400 hours on it. The tread wear is showing about half the tread is gone...

We joined the flat tire mono club this past Tuesday, only we think ours had a different cause, not rubbing of the tube in the tire.
We have been doing a lot of training on a hard surface runway. The tire and tube had in excess of 500 landings on it. We thought before Heather flew on Tuesday that the tire looked a little low and thought the same before Jim flew after Heather (she did 7 T/O and ldgs). On Jim's 7th landing, the plane slowed quickly and there was a smell of rubber.
When we took the wheel/tire apart we found that the tube was perfect except the valve stem was pulled off. No holes or rub marks on the tube. Tire was damaged with a couple of broken cords and a cut on the outside from the wheel.
Our conclusion is that the tire was low (we normally run 18 psi) and over the course of 14 T/O and ldgs with some swerving on the runway, the tire pulled from the bead of the wheel and rotated causing the valve stem to be pulled off.
The damaged tire was a US Speciality Tire AIR TRAC size 7.00 x 6 6 ply rating and the tube was a Cheng Sing (we think we got the tube from Europa UK).
We were able to get a Goodyear Flight Custom II tire locally and fitted our spare tube that is Chinese and purchased from Wicks Aircraft supply, Part Number TB-MTAT8X6 (tubes with the 90 deg valve stem are not listed on Dresser Tire or ACS websites). The only marking on the tube is "Quality Assured" and some Chinese characters! The new tire seems to have a flatter tread and doesn't bulge as much. Landings yesterday with it on pavement were no different than previously.
We always use a lot of talcum when fitting a tube. We inflate a new tube outside the tire first to get out wrinkles. Then we deflate it, talcum it (talcum the tire too), insert into the tire and inflate. Then deflate again, and fit the wheel (usually twice since we forget the spacer!!). Inflate again and deflate again. Finally inflate the final time to 18 psi. Be sure the valve stem is aligned with the red dot on the tire for balance.
When we got our Europa wheel, we found the opening for the valve stem was quite rough. We filed and sanded it to make it as large and smooth as possible. We used Scotchbrite to clean the wheel before fitting the new tire and tube. There was a lot of rubber debris on the bead and even inside the wheel.

First, I fly a tri-gear, so take this with a grain of salt. In racing,
it is common to "screw" the tire to the rim, using short pointed sheet
metal screw. Would this not be workable in the nomowheel to prevent the
tire slipping on the wheel?

...and in dirtbike/motocycling, the low-pressure tire is clamped to the inside of the rim (a "rimlock") and tightened with a with a simple bolt. as per: http://www.motorcycle-superstore.com/2/9/203/4355/ITEM/Motion-Pro-Alloy-Rim-Lock.aspx
Pity there nothing similar for the low pressure Europa wheel.

I remember once listening to a presentation by a professional engineer and pilot at an EAA meeting.He pointed out that it is very important to make a permanent mark on the rim(s) and on the tire after tube installation. And this should be checked as part of every preflight inspection. Apparently this slippage is quite common, regardless of aircraft type, when landing on hard runways.

This has always been my habit (similar markings also to the oilfilter & base as well). Just do it simple by red permanent marker. I have never seen any movements between the rim and tire/tyre. So that is not the reason for once-a-year-flat-tyre-syndrom in my case.

Our conclusion is that the tire was low (we normally run 18 psi) and over the course of 14 T/O and ldgs with some swerving on the runway, the tire pulled from the bead of the wheel and rotated causing the valve stem to be pulled off.
The damaged tire was a US Speciality Tire AIR TRAC size 7.00 x 6 6 ply rating and the tube was a Cheng Sing (we think we got the tube from Europa UK).
We were able to get a Goodyear Flight Custom II tire locally and fitted our spare tube that is Chinese and purchased from Wicks Aircraft supply, Part Number TB-MTAT8X6 (tubes with the 90 deg valve stem are not listed on Dresser Tire or ACS websites). The only marking on the tube is "Quality Assured" and some Chinese characters! The new tire seems to have a flatter tread and doesn't bulge as much. Landings yesterday with it on pavement were no different than previously.
We always use a lot of talcum when fitting a tube. We inflate a new tube outside the tire first to get out wrinkles. Then we deflate it, talcum it (talcum the tire too), insert into the tire and inflate. Then deflate again, and fit the wheel (usually twice since we forget the spacer!!). Inflate again and deflate again. Finally inflate the final time to 18 psi. Be sure the valve stem is aligned with the red dot on the tire for balance.
When we got our Europa wheel, we found the opening for the valve stem was quite rough. We filed and sanded it to make it as large and smooth as possible. We used Scotchbrite to clean the wheel before fitting the new tire and tube. There was a lot of rubber debris on the bead and even inside the wheel.

Hi All,
Jim's comments prompted my to share some additional thoughts. I found that my new tyre "stood taller" than the one I replaced. My theory is that the old tyre was run at low pressures so long that the side walls lost their strength. I think the design pressure for this tyre is something like 35 psi.
The other comment was that I did loose one inner tube to slippage, and two tubes to side wall wear so I increased my running pressure to around 22 ~ 24 psi. I used to have a maker on the side, but I forgot to put in on this time so thanks for the reminder.
I do have a question to the forum. is is possible to seal the split rim and turn it into a tube less configuration ?

All,
I think the side wall wearing is the point and that will be high-lighted when a low pressure, not a quality tube, ageing, bad manners when installing and a wrong tube size.
Check this,

this for a quality

and this for nose-wheelers:

Also, consider using Nitrogen instead of air. There are many obvious benefits.

Jim and all
The problem is to find and get high quality tubes. There are many top-of-the-line tube brands like Michelin or Good Year but they do not have types with a valve stem bent to 90 degrees. They say tubes with 90 degree valves are only for light aircrafts and their owners do not pay for quality. They claim they buy only low prices and offers...
However, brand name Leakguard by Dresser promised to make size 7.00x6 with a valve stem 90 degrees as a special order.
We do not have Leakguard model because the 90 degree is for Light Sport Aircraft.
I can have special order these in Aircraft Grade, Leakguard with 100 pcs. minimum at $42.95 each on 100 pcs. order. Delivery 60 days.
Maybe you can get the owners together to buy 100?
Best regards
Steve

I purchased the tube whenI purchased the tire from Dresser.....Sorry I do not know the name of the tube...Your outlined plan seems to be well thought out.

Hi Jim,
have you any idea what is your tube brand name? I think that (the tube) could be something between happy landing and a possible disaster or pain at least.
***
To prevent future tube-related accidents my plan is to go as follows:
1) change a very best available tube (www.desser.com , McCreary ?)
2) change it for new one regularly ie. once a year to prevent it is ageing.
3) consider seriously what is the best size for it (must be same as tyre and that is in my case 7.00-6)
4) install it with extreme care and baby bottom talcum
5) keep a good tyre pressure ie. 2,0 – 2,2 bar
6) fill the tyre with some well known pre puncture liquid (www.slime.com ?)
7) have a low tube pressure on-flight control system (www.conrad.fr ,thanks Alain)
carry always in a plane a spare tube (with a lifting block)

Raimo; sorry for the delay... The tire is a Goodyear 700X6 6Ply rated. This tire has about 400 hours on it. The tread wear is showing about half the tread is gone...

Dear Jim
Read careful my post: I like to use pressure 2,0 - 2,2 bars. 2,1 bar = 30,45 PSI. So we land with same pressures. Pressure - low or high - is not a reason.
What is your tube brand name?
What is your tube and tyre size?
Until I will get a reason and solution I am going to do same as Paul is doing: changeing regularly tube. Makes me sense to change it every year (= in my case every 50 hrs /about 50 - 100 landings. I never can do it in 30 minutes but so what. Tube is very cheap. For example yeasterday I spent 6 hrs fighting with that problem with my wife and that newspaperman. That is 18 hrs + all the extra fees + 400 km driving car. That must be same as buying let us say 100 pcs of tubes.
BTW also I use masses of baby bottom talcum. That delicate scent is a bit embarrassing...

All monowheel drivers
Following this thread today... I have a few commits to throw to the forum...I notice that Europa requires very low tire pressure in their manual....
I also noticed today that quiet a few monowheel drivers are having flat's....I suspect that with the low air pressure, when you land the sidewals are flexing due to low air pressure...this is probably "pinching the inner tube" and then the tire goes flat....
I have always kept 32 PSI in the tire. IN 10 years, and two tires and tubes, I have never had a flat....Yes I know I have been blessed by the good luck god..
Thank about it with 32 P S In the tube the sidewalls are not flexing......Just my thought's on this matter....

I have found that the inner tubes on my mono to be an ongoing problem and I
now routinely change my inner tube every 150 hours as preventative
maintenance. The tubes I have been using are not very expensive and I think
that they are from China. Recently Bud made me aware that there is a
certified inner tube available at about 3 times the cost and if they last
longer then they would be so worth it!
I do recall when I mentioned on the forum that I was losing inner tubes
regularly that some people were surprised and that they had not had a
problem so perhaps this can be accounted for by different inner tubes being
available. The failure I get is that the side wall of the inner tube get
small splits in it due to chafing. I typically run my tire at about 24 psi,
which is higher than the recommended by Europa. BTW I do use talcum powder
when I install the inner tube.
I have had 3 blow outs on a hard surface and fortunately I was able to keep
directional control. The challenge I found is that with a flat tire the
mono is nearly impossible to move. It happen to me at a large airport once
which got the airport authority excited because they had to shut the runway
down and divert all of the 737's to a shorter runway. I now carry a jacking
block, tools and a spare inner tube with me and I can now do the change out
in less than 30 minutes.
Next time around I am going to try a certified inner tube in the hope that
it will last longer.
