Dad's buddy donated me a set of BFGoodrich T/A Radial tires for my 71' roadrunner. Normally reading a tire size is easy just curious what "SR" means on the tire size. The measurement of the tire is 285/70SR15.

R means radial-ply construction.
Speed rating. This letter denotes the maximum sustainable speed and is found directly after the load index. For S-speed-rated tires, it's 112 mph; for T, 118 mph. Speed ratings for other tires include Q, 99 mph; H, 130 mph; V, 149 mph; and Z, 150 mph plus. While such speeds may seem wildly impractical, tires with higher speed ratings tend to provide better handling at legal speed limits.

That's a big tire. You want to put them on the roadrunner? Those would be better suited to a fullsize truck :lol: . Almost 31"s tall.
