My back tires are may-pops, wires are starting to show on the drive wheel, so I'm looking to get new ones all around. The guy I bought the car from put 205/50/16s on and I know stock was 225/55/16. How big can I go with the pony rim and no modifications to the fenders and quads? Would 245/50/16s work on them? What about 275s? Also, should I go with a smaller tire on the front than in the rear? I asked a guy at the tire shop in town and he tried selling me MT ET Streets for all four wheels, so I don't think he could help me with the sizes... Would 245s be too big for sharp turns on the front?
