After the size, a tire is marked with a load index and a speed rating, for example 94H. Both matter for safety.
Load index
A code for the maximum weight each tire can carry. For example, 94 equals about 1,477 lbs per tire. Always meet or exceed the load index your vehicle was designed for — especially on trucks, vans, and SUVs that tow or haul.
Speed rating
- T — up to 118 mph
- H — up to 130 mph
- V — up to 149 mph
- W / Y — 168–186 mph (performance tires)
The rating reflects sustained-speed capability and is tied to the tire’s construction and heat resistance. Match your original equipment rating unless a tire professional advises otherwise.
Verify the correct load index and speed rating on your door-jamb placard before ordering.
