After struggling with the straight tube OEM Vans inner tube, I decided to go to the Aero Classic from Desser Tire TU15/600-6. My experience with this tube has been awful. I went to this tube due to the nice 90 degree bend in the stem that allows easier filling with air. By removing a small bit of metal on the wheel bearing cover, you can easily fill this tube with air. My left side failed after only 6 weeks leaving me with a flat tire when I was ready to dispatch the plane for an important flight. Since I was inside of 90 days, Desser gave me an RMA and I got a credit (not refund) on the defective tube. My second tube failed just this last week after about 5 months of flying. These tubes (made in Thailand) are just no good. I reinstalled my old Vans tube on the new Michelin tire on the left side, but I have yet to put the old tube back on the right side. These tubes are just crap. Any suggestions or comments on this issue will be appreciated.

That's odd- I've used these same tubes for three years without any problems.

I'd like to know what/where the failures were.  I suspect poor assembly 

rather than inherent failures of the tubes.  Or poor assumptions 

relating to the mod. If you used the same hole in the wheel that was 

used for the straight stem .... there's your problem.  The 90* stems 

line up with the parting line in the wheel and require a hole in the 

parting line and another hole in the side of the outside wheel half.  I 

converted my Vans wheels to 90* stems. I flared the inside and outside 

of the original stem hole and filled it with flox.  Not flying yet so 

don't know if my 'mod' is successful.

I had an issue where an inspection sticker inside the tire wore a hole in

the tube - I thought I got a bad tube...until I wore a hole through the

patch as I put it back together the same way it came apart.....

I have the same TU15 Desser tubes, and probably have the longest life on mine as I got some of the first ones released. I have gone against the" replace tubes with tires" minds and reinstalled the tubes on the new Monster tires, to date I have had no issues of leaking at all, that's is after 4 years of flying.

I'll assume the tire pressure is more than 42psi? I run mine at 48psi and never let them get below 44psi, I am concerned with lower pressures pinching the tires or rubbing and my pressures seems to work as my tires look pretty good for tread, I have no shutter (unbalanced rim still) with solid traction.

I can only think they changed manufacturer since I got my tubes. Unfortunately, I really like mine thus far and would buy them again. How are the Vans tubes working out? Was it only on the left side? Both times? What about the right? Is that side fine? If so, there may be something on the left causing the issues, and your Vans tube may be the next to go on that side... just thinking....

I had 2 tubes fail from Desser, not all that many flying hours apart,

also.  But, mine weren't the 90 degree valve stem tubes.

One of them was a pinhole leak that just came out of nowhere.

The other was a leak that was along a little slice-like

scrape, that I have no idea how it got there.  Admittedly,

I didn't thoroughly inspect the tube when I pulled it out of

the bag.  I wasn't happy in either case.



Both wheels now have new-ish 90 degree stem tubes in them.

I've always run my pressues at the standard 42/40 rear/front

pressures that Van's put in the original manual, however I

think I will start raising the pressure slightly just

because we have such large temperature swings here, so if

I check them in the fall I'll go maybe 48.



Linn,  I think you're mistaking his issue for the nosewheel

tube.  Yes, on that one Van's sends the wrong wheel, and

then they have to re-machine the hole on the other side,

and all the things you said.  But he's talking about the

15/6.00-6 main tubes.  Those don't require any drilling

or anything else.



Other than these 2 tubes, I've had good luck over the past

10 years. I've replaced tires a few times and always put in

new tubes.  So I'm not sure I'm ready to ditch them

yet.  I WOULD be interested to see what the BEST tube

available is.  I would prefer to buy a US made tube if

at all possible, and would pay a small premium for that

ability if it's a quality tube.

Tim, I had to machine both my mains. That might be due to the tube 

manufacturer being different.  I'm guessing from your post that you used 

the same hole as the straight stem??

Yes, same holes. You have Cleveland?

That's what mine are.

Yes, they're Cleveland.  However I have a tube with 90* stem in my shop 

that has the offset to fit the straight stem wheel.  It would point to 

the outside of the wheel, not parallel with the axle.  I think the tubes 

I have came from Desser, but were not the Leak Guard.  The stem is in 

the center of the inside of the tube, and when mounted the stem is 

naturally parallel to the axle, so that drove my mod.

I did not put a new hole in the rim as the tube stem lined up fine when installed. The leak on the left tube that I returned to Desser was in the side wall of the tube. There was no abrasion on the tube, but it appeared as a "casting" flaw in the tube where the leak originated. I have not taken the leaking right tire tube off yet to diagnose the issue. Desser will not give me a refund after 90 days.

Has anyone ever used that slime stuff to stop a leak??

 Good thoughts on the subject. Gotta get my patch kit. Yes, you definitely want to turn the tire to distribute the material. 

 

 Another thought is that if you cannot spin the tire vigorously as in jacking and spinning then you want to taxi quite a bit to distribute the stuff and see that it covers the interior of the tube.

 

 In the mean time, it looks like "Aero Classics" has changed vendors and the QC is not so great, or that I just got a bum batch. Either way, it is a pain to mess around with the tires that much after spending $400 on new mounts.

 

 PS did you or anyone else put air access doors in their wheel pants?

Any cirrus parts house (service center) will sell you a plastic wheel pant plug. It's 2" in diameter and made out if white plastic. It can be painted. Center of the hole works well 2-2.5" aft of the axle screw and 1/2" down. Pretty simple mod.

Lowes also sells metal plugs of various sizes that work great.  In the hardware section in the specialty bins.

I have to think you got a bad pair of tubes. I bought the exact tubes that were recommended on Tim's web page, probably around 3 years ago when I was mounting the gear legs. They are the Desser Leakguard variety, inside Desser standard recaps. I have been flying since April, and most add air every 6 wks or so, which is aggravated by our major temp changes. I suppose I should get a patch kit to put in the airplane spares kit.
