Question on alignment and tire wear - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

EM1/SS · 06-01-2015, 03:54 PM

I have mostly BMR bushings, toe rods, and trailing arms on my SS. After I changed to these I went with the Pedders street performance alignment. The rear alignment specs are not that much different from the OEM, rear camber went from -0.4 to -0.5, but I went through a set of rear P Zeros in 3300 miles. I do not drive the car too aggressive (I don't think I do). They look like the wear is somewhat even. The outer edge is a little lower than the rest, but not by much.

Do I have some other problem or are the tires just that soft? I see others getting 15k or more.

I sent this in a PM to justice Pete a few weeks ago and never got a response. Any one?

3300 miles on Pzeros is a little low. They should be able to get at least 15-20k miles before being replaced. Is is both front and rear wearing so fast?

Most likely a toe issue, toe is what will kill tires, not so much camber. I run -2.1 camber in front of my car and haven't noticed any major wear on the front. If you have a lot of toe though it will eat tires very quickly.

I've put well over 1k miles, had almost 4 hours at VIR and 2 autocrosses on a new set of M/T Street comps and they're looking just fine even with the -2.1 camber up front, and I have close to -1 in the back, but very little toe.

Once upon a time, my LCA bushing in the front of my car went out and affected my toe settings. It ate through my tires in no time.

The fronts are fine it's the backs I have trouble with. I had it aligned to the pedders spec's 2 years ago. I watched the guy do it and he got it right in. The spec's call for 0.10 total rear toe. That does not sound like a lot.

The alignment can get knocked out of spec. Those tires lasted me 4K and I tracked them when I first got my Camaro. I'd have the alignment rechecked.

Yeah, 2 years is a long time to go without an alignment, it's most likely out of spec now. I think it's typically recommended to get it re-aligned about every 6 months. Honestly I go about a year though without any issues normally.

Pot holes and rough roads will eventually just knock it out of spec.

EM1/SS · 06-04-2015, 06:38 PM

I'll get it aligned again and see if it was off.

EM1/SS · 06-13-2015, 08:43 AM

It was the rear toe that was out.
