Thanks for the info. I think the 60 series will go nicely in the aluminum tubs, so no worries.
i found a local dealer that'll supply a pair of Cooper Cobra GT's at 275/60R15 for $104 CDN balanced and installed.
Now I have to decide on rims. Was gunna go with 15X10 Keystones, but if I'm spendin the money, I may want something with some 'flash'. I like Rallyes, but they're too expensive, and are 'common' for Challengers. Since the car is all black and green, I thought plain black wheels would be neat, but maybe I wanna bit of chrome, too?
decisions, decisions....
