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

 

looks fine to me that is the heat building up and shreding the outside of the tire, it means you are actualy using the tires for what they are intended for.

 

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?

 

I would say you want NEGATIVE camber on the rear (and the front) rather than positive camber. You are riding on the outside of the tire and skiving rubber on any hard turn.

 

my bad, the 1.44º is actually negative, forgot the '-'
front is -1º

 

In that case, more pressure might help.

 

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.

 

just chalk some lines across the tread and see what's left after some hard driving?

 

dude... you guys are running way too high a pressure. I've found that anything over 30 psi cold and I start losing a lot of traction. if your sidewalls are folding too much add more negative camber (or add caster on front) or get stiffer tires.

 

i run 30 psi in the rear and 32 in the front with my 225's just fine.

 

I'm running 14's on the track.

 

yep. Common sense will tell you what to do from that point. you can use spraypaint too.

 

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.

 

Why run more negative camber on the back than the front? Isn't that kinda pointless?

 

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: )

 

I was told you'll want something like half a degree more camber in the back than in the front, handling-wise

 

to reduce exit oversteer...but also makes trail braking much easier.

 

OK... here we measure it in degrees or distance, your weird Nordic alignment specs mean nothing to us. :gay: For all I know your rear tires are toe'd in 20 degrees. What "US" toe are you running?

 

lol
