I have a set of 15 inch wheels for my 85 supra. the last owner has put a set of 205-60-15 on it. Do you think i can put a set of 225-50-15 on it. What is the acceptable percentage for the reading and actual speed.
Thanks

Eric

Type in "tire size calculator" in you search engine. There are several sites for doing that. Or call TireRack.

no need to type. We have one linked to this forum. In fact go to the wheel and tire page. It is the third post. use the second link. the one for the miata site. Its is easier and has a graphic view.
