EDIT:: I'm pretty sure the large amount of toe was responsible for this .

Outter:


Is there anyone else out there experiencing similar wear?

45 PSI is way, WAY to high. I run these tires on my Mazda3 at 35 PSI and have seen very little wear over the ~20K miles I've had them. What your showing in those pics seems more like an issue with your car, than the tires. Something isn't right if you're wearing the inside edges that much more than the rest of the tire.

the inner wear is due to the toe being something other than '0'

the outer wear is due to not having enough negative camber and having ****ty suspension and too much body roll

and TOO much pressure


and done

Do these initial numbers look like it would have caused the wear, specifically the toe? I left out caster because it was right in the middle of spec, and didn't change after the alignment.

First 7000 miles with:

Front Camber: -0.25, -0.21
Rear Camber: -1.02, -1.29

Front Toe: 0.20, 0.20 !!!!!
Rear Toe: 0.22, 0.15 !!!!

After alignment:

Front Camber: -0.29, -0.53
Rear Camber: -1.03, -1.28

Front Toe: 0.02, 0.00
Rear Toe: 0.02, 0.03

The front toe was way out. Would nearly double the max spec of toe (total +0.40 front and +0.37 rear) cause that kind of wear? If so, I'll gladly take back my view on the tires.

...And thank you. So it seems they were ruined in the first 7000 miles. Damn I knew I should have had it aligned after I bought it, it just didn't pull or anything, so I procrastinated.

....don't feel too bad. I ruined two good sets of Pirellis due to bad toe settings, an incompetent alignment shop and laziness (on my part).
