Here are the alignment numbers for my last alignment after the PSS10 install. Looks like the rear camber is slightly out of spec. The pics are not great. Sorry.


FL, FR
camber -0.30, -0.40
caster 5.40, 5.50
toe 0.06, 0.04

RL, RR
camber -1.60 , -1.70
toe 0.13, 0.16

F, R
cross camber 0.00 --
cross caster -0.10 --
total toe 0.09, 0.29
thrust angle --, -0.01

I can't see it! where is the wear? Is that it in the second tread block from inside?

What kind of TP do you run?

As per Robin's alignment page on pcar.com, it looks like your front is a bit out of spec on the caster (he says 5°20' + 15', whereas you've got 5°40' and 5°50'), and the rear camber looks out of spec as well (he says at most extreme RS specs -1°20'±10', where as you've got -1°60' & -1°70'). It looks like that would explain the fast wear on the rear at least. I'm sure someone smarter than me will chime in on the rest.

I agree, I don't see it either, though I'm not to well versed in these things. I do know that right off the rack the depth dimensions can be less toward the edge of the tire than the center region, perhaps they are wearing evenly after all? Do you have a tread depth gauge?

I had a comment from a friend just recently that I'm running too much neg. camber in the rear and that the inside edges will suffer for it. The place where I got my last alignment advised I bring the car back at 3k miles to check the wear patterns for any issues, and I'm at that point now, so I will go in and report back here if I find anything pertinent.

Sorry if my explanation or questions are dumb, just trying to help.

Here are my alignment specs:

Front Left:
Camber -1.44*
Caster 5.53*
Toe 1.8mm

Front Right:
Camber -1.43*
Caster 5.52*
Toe 1.8mm

Rear Left:
Camber -1.71*
Toe 1.9mm

Rear Right:
Camber -1.71*
Toe 1.9mm

What's your pressure set at?

Thanks Mike, the car needs a new alignment anyway. I'll try to get it closer to Robin's specs.

I try to keep front and rear at 36 psi.
