tire wear question
Just put my old tires on to burn up, so I had my 1800 miles old toyo t1r's off, and I noticed the outside edge seemed to have more wear than the insides..
my old tire wore nicely even, inside just a tad more, and since the new toyos the car was aligned too...
I'm running 32psi front and 34 psi in the back, what would cause this funny wear pattern?
outside edge:
inside edge:

edit: I'm running toe-in 0º6' and -1.44º of camber in the rear according to the alignment spec sheet

sure?
seems that the tire is using more of the outside during hard cornering, and the floppy sidewalls allow it, either a tad more pressure or more camber to keep it more 'flat' i.e. more contactpatch instead of running the sidewall on the tarmac?
or leave as is?

get the chalk out, it will tell you what to do.
My azenis look like that too on the 14's.. I run at like 32psi cold on the track, it grows to like 38psi. Any more pressure and i slide all over.

Chalk the tire across the tread AND down onto the sidewall too. Chances are it's like Magna said and you are simply using the tires for their intended purpose.
I don't understand your toe-in number though, to me it reads "toe'd in zero degrees, six feet". Toe-in could be contributing to the problem too, but I'm curious how much you run. I used to run 1/4" in in the back but found 0 toe much more fun.

here we measure the toe in degrees, minutes and seconds, hence the ' and ''
so it reads zero degrees, 6 minutes.
(or something like that:gay: )
