I have a set of Toyo Proxes T1R's with less then 500km on them, more like 250km or around there.. They are 215/35/ZR18's. Currently they are mounted on O.Z Superturismo GT's, but I'm sure they wouldn't do you any good since they were on my previous car (Focus ZTS). Heh. I'm putting a Stage 2 ZZP turbo kit on my 07 Cobalt SS. I just looked and these go for about $860 a set online. Open to trades and offers I guess. Appearance, Performance, whatever is out there.

I'll get a pic showing tread depth, but here is a pic of them on my old car.
