Bumping this thread to see if more people can report how many miles they got out of the oem Bridgestone Potenza RE050A's. My car has only 1700 miles on it, but I had to replace one tire due to it getting a piece of metal in it where it couldn't be plugged and patched. The new one had 10/32" of tread, but to my surprise the other three were already down to about 8/32". If you extrapolate that out, they'll need to be replaced (by 2/32") by only 8000 miles or so.
The car was driven gently for the 1000 mile break-in, since then I drive fast around corners when I can, with a lot of regular cruising around mixed in. No burnouts, autocross or tracking. I know it's a performance tire, but would still hope to get 10-15k miles out of it. What are some more of you getting, and what's your driving style?
