I have 4 good perrelis on the car, stock 18" tires just replacements. The first owner didnt rotate his tires like he should have but these tires ware funny. The side treads are wareing lower than the center patch. Nothing is wareing out like it has a toe problem, its just the side treads are shorter. Are they like this new off the shelf? I have a rear tire thats making a lot of noise like its wobbling but there's no vibration, just lots of noise. Are the stock perrelis crap or do I just have a couple bad tires? Any thoughts?

 

under-inflated?

 

I am just wondering what you run your tire pressure at? If you are getting wear on the outter and inner edges of the tire but not much in the center, you are probably looking at under-inflated tires. If they are the Pirelli P-Zero Rosso's, they shouldn't be super noisy. I know mine aren't very noisy at all.

 

The tires are P-Zero Nero. They have ~30psi in all 4, which I expect is about right for an 18" dub tire like this. If I werent broke I'd buy some light 17's with taller sidewall tires. I dont think its under or overinflated tires. I'll have to get a picture tonight, its really weird to look at. The side tread is like 1/4" lower but perfectly flat just like the tire has offset tread.

 

You should be running 32psi minimum. That is the factory recommended tire pressure. Fuel mileage will suffer and your tires will wear as described if you run less pressure than that.
