What is the best setting for mainly street driving (ie max tire life)? Ive been driving about 30k miles a year in my S and at my current rear toe (i'll have to look for the sheet to get the exact setting, I know its on the high end of the OEM allowed specs) and -3 camber im getting 10-15k out of my rears which are hankook v12 evos. In contrast the fronts will go to 30k at 0 toe and -2 camber. I do occasionally drive the car hard so I don't simply want to goto garbage touring tires for better life, but at the same time i've been told that zeroing or nearly zeroing the rear toe is asking for a death sentence on the street. However i've auto-x'd and drifted the car so im pretty familiar with its characteristics.. Any insight and suggestions are much appreciated. Thanks.

 

These cars tend to wear rear tires at a rate of 2x vs. the fronts. Everything sounds pretty normal to me there.

When your tires are worn out, what does the wear pattern look like?

 

i run 0 toe in the rear and havent noticed a difference in wear versus having it with toe in. Makes the car WAY more stable straight line in my opinion as well.
I should add, I autox and live in the mountains too.

 

If zero toe is death sentence on the street, what are you really doing on the street?

 

Pretty terribble wear on the inside inch or so of the tread and sidewall tread. The rest seems pretty even besides the obvious camber wear...

Have you ever had the car break loose unexpectedly on you? Like in the rain? I'm not sure why everyone is telling me 0 is such a bad idea...


I don't drive it hard on the streets ever.. Unless its in a straight line 1st through 3rd (sometimes 4th ) to 9k

 

Horrible pic but yoou can see the extreme inside wear..

 

I run 0 toe too and haven't had any issues. I really wish our suspension's toe was linear under compression, but since it's not and there is proof that it toes inward in the rear under compression, why bother with toe in while static? It's just going to adjust your feel and becomes part of the overall suspension tuning to your flavor at that point. You can combat tail happiness in other ways besides making your tires work against each other.

 

If the inside of the tires are wearing faster than the rest, dial in a little bit of toe-in. I had mine set at 0 in the rear for a while, but noticed that once the car starts moving, the rear toes out a bit, causing the inside edge of the tires to scrub. Dialing in a small amount of toe-in actually translates to a roughly zero static toe. I'm at -3.5 camber in the rear with factory toe-in specs and have gotten even wear with the front tires going on almost 30k miles now.

 

Run .10-.15 a side out back, should be good to go. Thats 2 to 3 total. Check your tire pressure too. I found when i was running more camber, i would drop tire pressure to plant the tires more, but the results were poor on inside tire wear. Add some tire pressure if need be, 32-35psi cold range.

 

^^^ What Junky said. I've been running 0.2 degrees total on street and track for a while now. When I did try big rear toe (max spec, ~0.65 degrees total), all it did was make the handling wonky (unstable in a straight line, understeer on corner entry) and give me 2x-3x the tire wear rate!
