Just picked up non curbed OEM 18's with 95% rear winter Blizzak 255 LM60's and 80% Pirelli 225 Wintersports in the front on Craigslist. Mismatched front/back but for $850 it was like getting free wheels or free tires. There is some imperfections in the paint which I can fix if I really want to. We even test fit and I drove on them for 30 mins to make sure everything felt smooth at high speed, braking hard, WOT, and corners.
The LM60's did a good job at sticking their traction at full throttle from a stop without DSC activating in summer temps. On gear shifts with anything other than fully straight the tires want to wiggle a bit but not enough to engage DSC.
The ///M is ready for winter now!!!
