I picked up some 18" infiniti wheels and am having a tough time deciding which tire to wrap them in. I want a smooth, comfortable ride and I'm only using H&R springs in the front (rubbing won't be a factor). Tirerack says that I should go with a 245/45/18 so that my speedo is correct.

Long story short, I ordered Bridgestone 245/45/18's and they look HUGE in diameter compaired to my OEM 225/50/17's. Is anyone using 45 profile tires on 18" wheels and liking the setup or should I send them back and go with 245/40/18" tires?

Thank guys!!!
