Cupping/shaving inner portion of tread on drive tire

That is the worst example but the other tires aren’t completely evenly worn either. You do have to expect some wear after 78,000 miles. I don’t run any balance products but I have heard Centramatics are good.

 

I’m going to drop the pressures down to 100 in the drives. I’m going to be on home time in about a week and I’m going to take it to the Volvo dealer and get the bearings and alignment checked.

 

People in this thread already told you where to take the truck for a high quality alignment. While you're at it have them explain to you how heat is built in a tire. Hint its not because of high air pressure...all mne sit at 130 cold and run about 145 hot. Never seen temps over 107* even in the Tx heat.

My money is on the alignment being out. Like said, new trucks DO NOT come aligned properly from the factory. They come "good enough".

 

Heat is created through friction and sidewall flexing. I tried to get it into one of the recommended shops today but they were booked out until tomorrow and I am scheduled to load out tomorrow and go to California. I’m going to look for a good shop in my home area and if I can’t find one I’ll just have to take it to Volvo while I’m on home time. I think you’re right about the alignment but I’ve also heard you can get abnormal wear on the edge is due to bearings so I’m getting those checked as well.

 

If you're an o/o then you dont have "home time". You make your own schedule. If my truck needs repairs, I go home and fix the truck because a repair on the road will alsways cost more.

Granted you've probably got a big payment due every month, so you gotta run enough miles to cover that alone.

 

MD Alignment Just click on the state you want and it will list the shops they have.

 

Know a number of people that run centramatics on all wheel ends. All have very positive reports.

Heat is the detriment of any tire. Sidewall flexing is the number one cause of over heating, usually caused by under inflation, followed by over loading. Scrubbing due to alignment will generate heat at the tread cap. Unless it is very bad, usually not catastrophic. The tread cap has lots of mass in comparison to sidewalls or the underlying plies.

 

Half of an inch is quite a lot for a tire, especially if it wasn't brand new, so I wouldn't wait too long before the alignment.

 

Check Alignment and bearings.... Centramatics are pretty good, but have heard good things about those balancing beads that go inside the tire itself. I believe MD Alignment sells them aswell, but I could be wrong.
