G744

A note from a guy that does all his own tire work and has for over 30 years: There are a lot of stories about "split rim" blowups.

Maybe so, I've seen a number of them go, but not in my shop. Those from pickup trucks, farm tractors, and old crappy trucks usually.

None of those blown has been the type wheels used on M-series trucks & trailers, the Goodyear LTS wheel. They are found on the G741, G742, G749, and G744 trucks.

It is not prone to that type of failure oweing to it's construction. A stout lip goes down into the junction between the tire & wheel to force you to lock it into place properly. Only when it is locked, will you have reduced the diameter of the ring such that the tire can come up under it and allow pressure to be built. If it is not locked, it will just push up off the wheel and let to tube pop out before you can get more than 10 psi into it

They are easy to tell as most are from either Goodyear or Firestone, the two big contractors for them. Some later ones are from Motor Rim & Wheel. All will have the letters "LTS" stamped into them along with the size.

The good type didn't come on WW2 trucks. The worst offenders are the Dodge 1/2 ton and the GMC/Studebaker duces like the CCKW.

They didn't come on a lot of commercial trucks from the 50's & 60's either, so beware some swapping about may have been done.

I use a commercial cage and a clamp-on hose when doing these tires just in case. But I can tell you from experience, and I have purposely tried to make one go "high order", it is just not a problem with the real LTS wheels.

I guess in the long run, all "split rims" are not made equal. The ones on your M35's are the best there was.
