Prostar drive tires?

Check out M D alignments Website, you might find some good info on there to help. Might check for loose bearings also.

 

Trailer alignment can also affect the tractor tire wear.

 

If it's only wearing out one side, sounds like an alignment issue to me as well. A good 3 axle alignment might be worth the investment. Plus, 5th wheel grease(or lack there of) plays a part in tire wear too. A dry 5th wheel will cause your tires to have to work harder to turn the truck under the trailer.

My Prostar with these stupid super singles is wearing the inside edge on all 4 drives. I think the company put super singles on a truck with axles spec'd for duals

 

The axles shouldn't have anything to do with it, other than alignment. You can put super singles on a bicycle as long as you have the proper hardware. Tire inflation is more critical on the big balloons.

 

Three axle alignment and make sure your 5th wheel always has enough grease on it.
Don't need the trailer steering the truck.

 

If the center or both shoulders of the tires were wearing, I would say inflation, but with the inside of all 4 means that there is something up with the geometry. The outside of my tires are way under the edge of the trailer compared to some with super singles that are out where trucks with duals are. Could just be the wrong offset wheel, but we also have inner wheel bearing failures and regular wheel seal issues. All from a truck with standard 40k drive axles.
