OK guys, what gives here???

These tires were rotated about 1000 miles ago. You can see by the dust pattern that both the inside and outside tread blocks are not wearing evenly. Fronts look the same, with the same pattern. Middle 3 tread blocks are perfectly smooth. Rotated religiously every 5-7,000 miles...........fronts go to opposite rear and rears go straight forward. Started noticing this about 15,000 miles ago. Right at 60,000 miles on the tires. They have good tread left. Cooper Discoverer AT3 4S. 2 years old.

Truck doesn't pull or vibrate; tracks straight, and is essentially 1 finger driving. Only thing is that it's loud driving down the road. These tires are singing opera at 40-50mph.

Thanks in advance.

The toe angle on your alignment is off. You could possibly have any number of suspension components that could be the culprit or simply be needing a alignment

What are your driving conditioners? I mean conditions...



I agree, get the alignment checked out first.

Shocks and air pressure. Maybe tighten up the rotation interval closer to 5K miles.

158,000 miles on her; and nothing done to front end except unit bearings a couple months ago.

Putting front tires to the opposite rears doesn't seem to even the wear though.

Rotating your tires cannot even out the tire wear because the alignment issue is wearing the outside of tires at a faster rate than normal.
A front end alignment should be part of a maintenance schedule listed in your owners manual or whenever you purchase new tires.

The "inside" AND "outside" tread blocks are wearing similarly no matter which corner of truck they're on essentially.
