Good day to all, im planning on upgrading my stock 18 (225/55/18) inch rims to 20'inch but am a little baffled on how high tires should be? Many tire sites recommend 245/35/r20 while others recommend 245/40/r20. Can anybody with a working knowledge prescribe a best fit. Im asking this ?ion because im from the Caribbean and its a little difficult to get that kind of expertise knowledge from way down here. Also some of the roads are not the best and i would rather 245/40/r20 but the question is will i touch when i turn to much or would it touch the shock. Ur assistance / comments would be greatly appreciated.
