Md alingment. Not a fan

I think someone is looking for a scape goat on bad choices they made.
I have used MD alignment get consistent 200k+ out of Michelin steer tires. Over 400k out of my drives. I pull at 6/32nds

 

I mounted a brand new tire on may trailer next to a lugger with deep tread. The new tire lasted 11k before it ate itself. The wear pattern started off similar to what's happening to yours, and it went downhill quickly. That's when I learned (on TTR actually) that the little tire gets dragged by the big tire, and will eventually start to skip down the road. When I got it replaced, the tire guy said the same thing as soon as he saw it.

 

I wouldn't be so quick to think just because some truck stop has the latest and greatest laser Alignment system that they actually know what they are doing or talking about.

If you were seeing tire wear after 500 miles something had to be seriously out of whack. Or the tire was wearing funny before Alignment. And remember tires are stupid, once they start wearing funny even after you fix the problem they will still continue to wear funny unless you change position/rotation

 

Both duals are attached to a common hub and axle end. I find it hard to believe that an alignment would cause bad wear on only 1 tire and not the other (or the tires on the other side of the axle for that matter).

 

Yes I had several Chad in KC alignments and everything turned out spot on.

 

110k mile difference between the two tires would be my guess, just as was posted before.

 

I think what he's saying is everything was fine like that for 40k miles, and 500 miles after the alignment the tire started to have issues. The circumference difference is a problem, but maybe it didn't start rearing it's ugly head until the alignment "helped it over the edge" so to speak.
