I've been doing some research.... the 215/55/18 from Goodyear says up to 8.5" maximum rim which sounds weird to me because all other 215/50 and 215/55 show up to 7 or 7.5".

Well I haven't been successful selling these 18" coddingtons and getting them to fit has become an experience. I would just redrill the brake drums to 5x4.5 to fit the wheels but then the wheel hub-bore would be too small to fit the huge hub on the car.

LoL
