The load range letter system is the only official load capacity identifier for all LT & ST tires. The load index numbers on LT & ST tires are there for speed letter displays, the medium for displaying a tires speed rating. A load index 125L has a speed rating of 75 MPH (“L” = 75 MPH).
For some ST tires the actual speed rating may be written (molded) into the tire sidewall. Any ST tire without a speed letter or written speed rating on their sidewalls will automatically default to a speed rating of 65 MPH. (There is no speed letter for 65 MPH).
