Look for something like 20X11X9 or 20X11X8 the first # is the how tall the tire is the 2nd # is the width the 3rd # will be your rim size.

hmmm, so its 20in tall form the ground? I have that size on my 250sx and its the stock sixe I think, I saw some 18x9.5x8 that looked a bit better ob ebay. So the rim is measured by height not width for the last digit correct?
