wheel sizes??

[89blaster89]

i want to get some new paddle tires, but i was wondering would 20x11-8 gbc sand sharks fit on the same rim that 21x12-8 tires came off?

they should fit fine. All you need to match is the last digit which is rim size. First digit is tire tallness and second digit is width of the tread.
