Bandit has 18s, they are little bitty tiny, I just bought some 20s and I though they would be smaller than my 22s but they are the same. As a matter of fact they are bigger than the 21s on the front. Somone clue me in? does these numbers really mean anything? they seem to defy logic to me. I just wanted some smaller tires and i figured if 22s are big, and 18s are small then 20s should be in the middle. However my conclusion is that:
Largest to smallest:
BIG

Tiny
