I have a set of tires that are 21/12.00/8 What size rims will work? plz help I bought a set of rims off of ebay buyt there too big :(

8 ..... last number is size of rim........ height/width/rim

The LAST number of the tire size and FIRST number of the rim size need to be the same to match up. The second number of each represent the width and there's some flexability there, i'm not sure what the limitations are but they don't have to be the same.
