Tire Wear / Adjustments

I ran my first autocross on my new Dunlop Star Spec tires a few weeks back.

I have a few questions about how my tires wore, and adjustments.

First of all I ran 45 pounds of air in all four tires.

My front tires wore well over the wear indicators.

The rear tires were well inside the wear indicators.

Is this a tire pressure issue? camber issue? or another issue?

well you have to think about how much your motor weighs, it's gonna smash the tires down a lil more. up them in the front and lose some in the back.

use some chalk on the side walls to help indicate too.

it's kinda weird though, i would think star specs could go with less psi then 45?

what tire size are you running?

I am running 215/40ZR17.

It could be a front camber issue...

Was thinking about going to check out the alignment, but I think I am going to install new springs and struts and that will put me right back at the start.

I've never needed over 38 psi with Hankook RS2's for front pressures. rear pressures were a couple pounds higher for rotation, but tire brands can react differently. The tires I ran couple weeks ago needed four pounds less in the rear too not to spin out.

If I recall correctly Scott was running 40 pounds in the front of his Star Specs on the same course in his Focus with some suspension work.

I am on a stock SVT suspension.

It was a pretty high speed course...

Don't take this wrong but you could be way over driving your car into a corner. If you are plowing into a turn and keep trying to turn harder you would be rolling the sidewall more. I have never seen you drive but its what I was taught when I was and still am learning.

No offense taken, could very well be true. I am new to all of this! :)

What are you alignment specs? Those, along with over driving into corners, could be what is causing your problems.
