    What would the difference be between a 113s tire and a 121r tire?
    Same brand, size, etc...

    Someone correct me if I am wrong but I beleive 113 and 121 are load ratings and S and R are speed ratings.

    A 113s tire can handle 1150lbs gross if properly inflated and can go up to 113mph and a 121r tire can handle up to 1450lbs if properly inflated and can go up to 106mph.
