Have 2 set of tires to set.
First set is OEM Re050 Run Flat from a 2008 135i 215/40/18 (front set up). My car currently at 33000 km, and i have winter tire as well, these set has roughly 24000 km max on it, never been track. One of the tire has a nail in the middle of it, didn't notice until i get it dismount from the OEM rims. You can see the nail from the pic.
Second set is Toyo R1R 255/35/18 rear set up for rear set up. Bought it in late October 2012. Been on the car for less than 1500 km max. 99% like new condition. Dismount the tires from the OEM rims at early December 2012.
Nothing wrong on both set of tires, reason of selling cuz i bought a set of 19" for summer, and also bought 18" yokohama W drive winter tires for the oem set.
