I'm interested in hearing how much wear your factory rear tires have and the corresponding mileage.

I purchased my '05 Crossfire used and I think the previous owner may have been a tad aggressive.
If he was it had no ill effect on the mechanics as everything tested fine.

Replacement tire size option for rear = 285/30 R19
Factory size is 255 35 R19
