Folks,I just got a second flat and the culprit was again the leakguard inner tube. If you're using these I recommend you get rid of them the next time you have your tires off or sooner.

The tube just wore through and leaked. I've never seen this happen to any other brand of tube.

Of course it happened at a rather inconvenient time, I was landing at Brown Field, coming back from Mexico, when you are not supposed to get out the the aircraft until the customs agent authorizes... I limped off the runway, pulled the wheel pant, and then limped to the customs box... fun fun.

Fly Safe,

Did you put talc in when installing?

I had a flat once on landing rollout - ended up being caused by a sticker inside the tire rubbing the tube.  I first thought the tube was junk - until I saw the wear pattern and the respective sticker....



Might not be your case here - but I thought I would share my failure mode.....

All of the talc in the world will not prevent an inner tube leak if there is dirt/sand/stickers/grass/rocks/etc between the tube and tire. Even a small grain of sand will cause a leak.  Imagine the pressure between the tube and tire and then add the punishment of high speed taxi/takoffs, braking and landings.

In my (limited) experience, a tube will       only wear through if assembled without talc or was underinflated.

       I talc everything .... tube, inside of tire and even the wheel       hub.Â  Extra talc on the tire bead will make tire removal much       easier down the road ... er ... airwayÂ              .

Had the exact same problem a few years ago with the Dresser No Leaks. 2 of them let go on landings (about a month apart).  One split on a seam, the other had cracks like it was 

old rubber and very poor quality. I don't buy Dresser tubes anymore. Mitchelin much better quality.

What Linn said, but more so.  I have over 1200 hours on a set of leakguard tubes that have been through three sets of tires so far.   Use copious amounts of talc, in my case plain ole' baby powder on all surfaces, always very slightly inflate the tube before mating the wheel halves to make certain that the tube is straight in the tire with no folds or kinks, even wiggle it around to make sure, then deflate just enough to mate the wheel halves, making certain that the tube doesn't get pinched between the wheel halves.  With all the talc you should have spread on the tube and inside the tire casing the tube moves around easily.  After the bolts are tight, partially inflate the tube again and bounce it on the floor a couple of times to again make sure the tube has no kinks or folds, then deflate once more and do it again for good measure before finally inflating to your desired pressure.  Takes a few minutes longer but sure beats flat tires.



BTW, with my leakguards my tires lose one psi or less in six or eight weeks.

Just to expand .... pun intended ....       when the valve core is removed I inflate/deflate the tube often       using my air gun to prevent folds that Harry talks about.Â  One       other problem I've seen are the wrong size tube installed ....       both too small and too big.Â  Happens a lot when the plane uses       5.00-5 on the nose and 6.00-6 on the mains.Â  Not all that hard to       switch tubes.

Been running Michelim Air Stop tubes since May 2005.  Almost 1,300 flight hours on the tubes according to log and not sure how many tires without going through the log more.  Also using plain old baby talc with procedures and service like Harry Crosby.  Looks like I had 1,671 hours on the tubes that Van provided.  They needed air once a month.

If you're using these I                 recommend you get rid of them the next time you have                 your tires off or sooner.

               

               

               The tube just wore through and leaked. I've never                 seen this happen to any other brand of tube.

               

               

               Of course it happened at a rather inconvenient time,                 I was landing at Brown Field, coming back from Mexico,                 when you are not supposed to get out the the aircraft                 until the customs agent authorizes... I limped off the                 runway, pulled the wheel pant, and then limped to the                 customs box... fun fun.

               

               

               Fly Safe,

I'm with you Harry, I've had the same results. I do carry a spare nose tire tube.

[quote]What Linn said, but more so.  I have over 1200 hours on a set of leakguard tubes that have been through three sets of tires so far.   Use copious amounts of talc, in my case plain ole' baby powder on all surfaces, always very slightly inflate the tube before mating the wheel halves to make certain that the tube is straight in the tire with no folds or kinks, even wiggle it around to make sure, then deflate just enough to mate the wheel halves, making certain that the tube doesn't get pinched between the wheel halves.  With all the talc you should have spread on the tube and inside the tire casing the tube moves around easily.  After the bolts are tight, partially inflate the tube again and bounce it on the floor a couple of times to again make sure the tube has no kinks or folds, then deflate once more and do it again for good measure before finally inflating to your desired pressure.  Takes a few minutes longer but sure beats flat tires.



BTW, with my leakguards my tires lose one psi or less in six or eight weeks.

Subject: Re: Leakguard tubes belong in the trash

In my (limited) experience, a tube will only wear through if assembled without talc or was underinflated.

 I talc everything .... tube, inside of tire and even the wheel hub.  Extra talc on the tire bead will make tire removal much easier down the road ... er ... airway    .
