Safety Ratings for Light Trucks & Some SUVs: Load Range

You’ll probably never need to get this technical but here’s some additional info on how your tires are constructed and the job they’re supposed to do.


You’ll probably never need to get this technical but here’s some additional info on how your tires are constructed and the job they’re supposed to do.

Load Range describes a tire’s ability to carry a maximum load at an industry-specified inflation pressure without deterioration of performance.

Passenger tires feature named load ranges while light truck and SUV (LT) tires use load ranges that ascend in alphabetical order. Letters further along in the alphabet indicate sturdier tires that can withstand higher inflation pressures and carry heavier loads.

A light truck tire's load range does not count the actual number of body plies found inside the tire, but indicates an equivalent strength based on earlier bias ply tires.

Most radial light truck tires actually have one steel and/or two or three fabric body plies.

  • Standard load P-metric will not show a load range but rather a load index like a passenger tire.
  • Extra load P-Metric will be identified with an XL, as in P235/75R15XL
  • Light truck (LT) and flotation tires have their load range listed with a letter, as in LT235/85R16/E or 31x10.50R15/C

The actual load the vehicle can safely carry is based on not only the load range or index of a tire, but also proper inflation. A Pep Boys associate will be happy to answer specific questions using our vehicle specific guides.
