I have pro comp extreme at 315/70/16 on my truck and all of a sudden the tires started to wear funny. I just had the four tires rebalanced 6000 miles ago ago, we went on a camping trip, tires were fine, made the next trip to work empty 1000miles, by the time i returned home the vibration was so bad that i could hardly see out the rear view mirror. when i looked at the tires all four are cupping on the inside/outside 1.5" of the tread, center tread is fine. Has anyone had problems with these tires like this?:dunno:

All that website shows is a tire that had been run on gravel roads on an overloaded truck.Running a load range D tires and hauling over the GVW of the truck.Not to mention that tire has less than 20% tread left if you look at the tread blocks yet he says it only had 7k miles.

You should rotate them every 5k miles.Judging by your comment your have about 7k on them since your last rotation.
How many miles total do you have on them? If they have been wearing fines and now all of a sudden 1 tires is wearing odd, maybe you have a hub bearing or tie rod issue. Did the wheel weight come off?
Just a few things to check, the tires are the end result of a problem no usually the cause.
Most true tire failures are tread separation or de-lamination.

Read my whole post! It is all four tires! I looked over the truck this week and found that the vibration was so bad that my brake caliper mounting bolts had come loose! I went to the tire shop that purchased them from, they would like to do an inspection of the truck, I will let them do it Only if its on they dime!! These tires were installed at 159000kms now the truck is at 183000kms
24000kms on them 15000 miles procomp treadlife warranty is 40000 miles. had a wheel alginment done just before installing these tires and it not out by very much and the check i did this weekend everything is tight on the truck. if it was one tire i could see the cause begin something on the truck! but ALL FOUR at the same time are doing this!

Sorry to hear about your tire problems. I'd suggest going to the tire shop and talking to the manager.

We have an '05 F-350 that we've worn out 2 different sets of ProComp tires with no issues at all... 1 set of Xtreme AT's, 1 set of Xtreme MT's

are you accidentally in 4wd? Or maybe the drivetrain is binding somehow??
