OTHER SPEED DESIGNATIONS IN THE SPEED CATEGORYS NOT MENTIONED…
F 50 mph (80 km/h)
G 55 mph (90 km/h)
J 62 mph (100 km/h)
K 68 mph (110 km/h)
L 75 mph (120 km/h)
M 81 mph (130 km/h)
For example Good years XTA in 10.00R15 and 215x75Rx17.5 trailer tires both in LR J – have a speed rating 55 MPH and a load rating of, Load @PSI - 6940/120…
Or the XZA 10.00R17.5 LR G at a load@PSI – 4805/115 with a max. speed of 65 MPH…
Speed ratings of 75 MPH or less are common for commercial vehicles… higher speed rated tires are primarily reserved for passenger cars and non-commercial passenger carrying vehicles…
Load carrying and speed are a dangerous mix… heavy load carrying and high speed are a deadly mix…
