speed rating
Tire's maximum velocity
A speed rating is a standardized measure of how fast a tire can safely travel under optimal conditions, indicated by a letter code on the tire's sidewall: The H speed rating means it's certified up to 130 miles per hour.
The term extends to other equipment rated for maximum operational speeds, such as electrical cables or bearings.
