Tire wear on front drives.

Camber/caster and Toe

In short wheel alignment..

It could indicate a bearing problem or it could just be the way the tires wear. I run continentals, GT's, and double coins on my trucks and they all wear that way. If I run Bridgestone's or Michelin's they don't wear near as bad on the inside.

 

Measure for a bent axle, worn inner bearing on the crown/pinion

Double check bearings, inside wear can be from loose bearings or a best axle. If it were the bearings and it's worn that much, you usually go through axle gaskets as well. It could just be the tires, we had a set of continental drives do that as well with no problem found. It was only the inside edge up to the 1st groove. The tire wasn't tapered, just that tread was wearing down twice as fast as the rest of the tire. Continental adjusted the tire cost and the problem never came back, so it must have been a crappy batch of rubber. It was only 2 tires out of 8 that did it.

 

suspension bushings maybe

 

Could be the rear shocks too, the Volvo I drive was having lots of drive tire wear, shop diagnosed it to bad shocks causing it and they were shot, new shocks, new tires and a three axle alignment and the problem seems cured so hard to say on the shocks, but they were bad, so maybe that was it, alignment wasn't that bad...
