I already did a search to see if any threads answered this question, and none did, so no grief about not doin a search ok? I have a 95 Cobra with 17x9 Cobra R rims, and need to replace the tires. I am currently running Bridgestone Potenza RE730's in 275/40/ZR17. I was thinking about goin to a 35 series for the sidewall, but what would the 275 change to in accordance with the 35 series? I want to keep the wideness of the 275/40's. Also, does anyone think that the 35 series will look stupid on 17's? Thanks
