I think the tires were fairly new when I bought my Roadster about two years ago. Had 36,000 mi on it. I now have 46,000 mi and the tires are still performing well.

I'm going to get a new set of F1's on my srt6 today. The srt6 has a mixture of original and replacement tires with 26,000 mi. Two of the tires were replaced by the dealer during warranty.

The left rear tire is cupping. The rear tires are also wearing more heavily on the insides.

All four wheel bearings have been replaced by the previous owner.

There is a lot of road noise. I'm hoping the new tires will help.
