When I started flying the 360 I kept the tire pressure around 35-40 psi. After several tube failures over several years I raised the pressure to the 45-50 range. That ended the tube failures, but I still see evidence of distress on the tubes similar to Scott’s photo, despite abundant use of talc. I have never had a tire failure.

 

I have never grown to like the harsh ride and excess brake use at the higher pressure, and am thinking about an experiment.

 

1… Thoroughly clean the inside of the tire and the tube.

 

2… Spray a thin coat of 3M High Strength adhesive on the inside surface of the tire and on the inflated tube.

 

3… Allow to thoroughly dry, at least 45 minutes, to allow solvents to evaporate.

 

4… Place the tube carefully inside the tire, uniformly distributed and inflate, without the wheel, to spread the tube inside the tire without wrinkles.

 

5…depressurize the tube and assemble the wheel.

 

The idea is to effectively make it a tubeless tire by bonding the two surfaces together, eliminating the chaffing. Has anybody tried this? What happened?

 

p.s. Randy, great video!

235/320/360 Tires, Legacy nose tire:
 
Well, I did it.....  I let my Lancair 320's main tire pressure hover around 40+ psi and the left main tube was wearing on the inboard side even though I am using Desser tires.  Same old pinhole tube leak result when I found it flat.
 
 
I will endeavor to keep the pressure at least at 48-50 psi.
 
BTW, I also bought replacement tires and tubes from Desser - interesting...........
 
The old tire was marked:
Light Sport Experimental Aircraft Use
Max Speed 62 MPH
 
The new tire:
Max Speed 100 MPH
Made in Vietnam
 
Both had the same information:
Load Range D
Load Rating 500 Lbs @ 70 psi
Tubeless
 
The tubes were different also in that the old stem was marked "Rim master" and the new one with "Whitehorse".  The new one also  had "Leak Guard" and "Butyl Tube" printed on it.
 
Oh well, they have the same part number.  Time will tell if the new ones are better.
