i have a 2008 g35x sport iwth 18" rims and im due for 2 new tires though im just goign to get 4 I think. I am not sure what tires to get. my car came with the dunlops i believe. I am lookin at the michelin primacy mxm4 which the guy at costco said is much better then the bridgestone Potenza (quieter, better warranty, good in snow/rain) but I dunno from what im reading its not really a sporty tire. how big is the sidewall on those? i dont race or anything but i do like to punch it every once in a while and drive 80-90+ on the highway. i also read the michelin pilot sport a/s plus is very good however they dont make taht size for my car but i guess you can use the other size. i live in new england so i def need the all seasons and something pretty good in the snow/rain. what do you guys suggest for my location and type of driving?
