Tire speed ratings

Re: speed ratings

There are no speed ratings for bicycle tires.

Re: speed ratings

Standard bicycle tires don't have official speed ratings. Official speed ratings require a tire to be DOT approved.

There's only 2 DOT rated tires that fits standard bike rims I know of offhand:

Coker Simplex Servicycle: fits 26" bicycle wheels
Pirelli ML75: fits 20" bicycle wheels

I've seen both with "J" speed ratings (62MPH). I believe Coker offers higher-rated tires tho. Here's a list of all speed ratings:

B - Up to 31 mph
C - Up to 37 mph
D - Up to 40 mph
E - Up to 43 mph
F - Up to 50 mph
G - Up to 56 mph
