I went in for routine service and was surprised to find my rear rear tires were bald in the center of the tread.

Two questions:
- has anyone else experienced this level of tire wear
- because my tires were only bald in the center, should I reduce pressure below the OEM recommendation of 30psi?

Thanks gm

Were you actually running at 30psi???

That sounds strange to have center wear at only 30

17,000 miles is pretty good for the stock performance tires. I just reached 21,000 and mine need to be replaced, but the previous owner must've driven the car like an old lady! I bought the car at the 15,000 mile mark and have put some pretty considerable wear on the tires

the obvious reason is that high performance tires arent a long life tire.

the reason why its only bald in the midle of the tire could be you were doing burnouts, the area where you live gets the road surface and thus your tires extremely hot expanding the compressed air inside the tire, or you drive for long distances at a single time.

those are my possible reasons. if none of those apply then i dont know

It happend to me at 17k to the tires suck...I just bought rims and tires instead of new tires.

if they're down the center...sounds like they are over-inflated.

Performance tires, esp the summer performance tires, are not made to last that long. I'm suprised you got 17,000 out of them. Usually if you're an agressive driver you get about 10-12k. The all weather performance tires may last a bit longer. It depends on how much performance you want to sacrifice for longer life.

I've got almost 23K on the original 18's. They look to be OK for another few thousand, but the noise is almost unbearable! From my research the pilot sports are still suppoed to be the best, so I will replace them with the same thing. To me, getting +/- 25k miles on ultra high performace tires like these is acceptable.

when should the 19's be replaced... like around how many miles

mine is at 15 and its to the tread wear

In the April issue of Super Street they tested the Pilot Sport PS2 against some competitors and the PS2 was ranked highest in wet traction and performance. It won overall by 14 points.

Study TireRacks graphs/test for wet braking distances from 50 mph..........shows a variance of 25+++ feet amongst brands models.

A [the most] critical factor that most tire buyers don't focus on!

I have almost 24,000 miles on my G, but am no where close to replacing the tires. The center tread is still very much there. So I am doing pretty good. I almost think that I can get 30,000 miles out of my stock tires.

I do drive a lot on the highway, however, so that may be a reason. Also, isn't 35 psi the recommended tire pressure, when the tires are cold? I have mine inflated to 37 psi.

Tread depth has very little to do with when a performance minded driver replaces tires-------when the compound " durometer" hardness measures a radical increase so that friction diminishes......usually when tread depth drops to half [4.5/32 ~~0.15"].

I took my car in for it's 15k service this morning... The dealer noticed the wear bars on the rear tires and recommended replacement (16k miles). They quoted $299 each ..
