What's with my rear tires?

[Midnight Shark]

I only have my rear tires at 30psi however the center is noticably thinning out more than the inner and outer regions. both rears have an equal degree of wear. Any thoughts on this issue? Is 30 psi too much? Fronts run at 30psi with -2camber however the wear is only on the inner region.

are those 18s or 19s?

just kinda curious, i'm running 30psi on my 18s as well....

If the center is wearing the tires are under-inflated. Try pumping them up a few psi.

You mean OVER-inflated. if only the middle gets worn it means that, its the only part in contact with the road,therefore getting the most wear

I dumbfounded as my tires are not over inflated, unless 30 psi is too much. I'm running 18's with Kumho 712's 245 rear on 9" rims.

30 shouldn't be too much.....

Oh, it just dawned on me. These tires that I have on are my summer tires which I did plenty of burnouts last year before slapping on the winter tires. Would burnouts eat up more of the middle of the tires?

Burnouts are a tires worst enemy…that could definitely have something to do with it. I would fool with the Psi alittle bit….it might be a little too high if just the center in wearing.

You have a combination of symptoms. The car is lowered right? Well the front's sound like you have some camber dialed in and some toe issues.

The rear could be burnouts, tire pressure (Check the door card for proper pressure) and you do not rotate your tires.

Here is a chart to help

I stand corrected, what I was talking about is for R-Compound tires.(unless im wrong again)
