I just bought some 15x7 3.5 b/s torque thrust d... they are being fitted to a 67 coupe with stock suspention and hight and no rolled fenders. I would like to go with 225-50-15 front and 245-50-15 rear. does this sound right or would i need to keep the same size and just jump to a 60 instead of the 50 series... any idea's or pics would be great
