Please forgive me if this has been discussed, but Is there an inner tube that can be used with the stock M35A3 wheel? From what I can tell, the CTIS set up of the rim makes it a bit different with the routing of the stem. I am just burnt out on battling my old leaky wheels and have been breaking my back replacing seals and fighting rust for years and want to be done with it.

Thank you for any input!

I have deleted all CTIS components many moons ago.

I had the same problem with 900-series super single wheels, so I cut a groove in each one to let the stem have somewhere to go. It goes from the stem hole to the end with the bolt-on ring, about 3/4" wide.

Tubes went in, I never looked back.

Depending on your rust issues? Wire brush the “O”
ring groove and we have had fantastic luck with tacky fuel tank sealer, or “aviation form a gasket”
And yes we ditched the “Ctis” system long time ago

I cleaned up my M35A3 wheels and painted the insides with high gloss black rustoleum after wire brushing the o-ring grooves. I replaced the grommets for the valve stems and torqued them to 45 - 60 FT-LB. I used nothing on my O-rings. My CTIS is still hooked up and functional. I don't have any leaky tires even after 11 years.

I think that either the rims or tubes would have to be modified to make this work. I considered tubes, but decided to just rebuild the rims myself. Where all my old 14.5R20 tires leaked, my new 395s mostly don't leak - turns out I have two that lose 0.05-0.1 PSI per day. I haven't chased down those leaks yet, and I'm not sure I will. It's a good idea to check tire pressure periodically anyway and top off the tires as needed.

Even with the CTIS wheel valves removed, check the brass fittings and their connections for leaks. My truck's wheels had several cracked brass fittings - like AM General bought them from the cheap bin :rolleyes:
