Speed Rating
Speed RatingThe speed rating of a tire is based on U.S. Government standards for reaching and sustaining a specified speed. Typically, a tire with a higher speed rating results in better handling. Speed ratings apply only to the tire itself, and not to a particular vehicle. Putting a tire rated for a certain speed on a vehicle does not mean that the vehicle can be safely operated at the tire's rated speed. |

Max Load
Max LoadA tire’s maximum load is the maximum amount of weight the tire is designed to hold. The tire’s load carrying capacity is directly related to the tire’s size and amount of inflation pressure that is actually used. Each load range has a assigned air pressure identified in pounds per square inch (psi) at which the tire's maximum load is rated. |

Load Range
Load RangeTire Load Range refers to the maximum weight a tire can safely support at a specified tire pressure. For Light Trucks and SUVs, ranges are usually expressed using SL (Standard Load) and XL (Extra Load or Reinforced). It can also be represented by letters (e.g., C, D, E), which indicate the tire's ply rating, which traditionally referred to the number of layers of material within the tire. A higher load range indicates a tire designed to carry heavier loads. For example, a tire with a Load Range E can support more weight than one with a Load Range C. The correct load range is critical for vehicle safety and performance, especially for trucks, trailers, and commercial vehicles. |

Tread Depth
Tread DepthTread depth is the distance between the top of the tread rubber to the bottom of the tire's deepest grooves. In the United States, tread depth is measured in 32nds of an inch. |

Max Inflation
Max InflationA tire’s maximum inflation pressure (PSI) is the highest "cold" inflation pressure that the tire is designed to contain. When measuring a tire’s max PSI, it is important the tire is "cold," because warmer temperatures can cause the tire pressure to temporarily increase resulting with inaccurate readings. This measurement should only be used when called for on the vehicle’s tire placard or in the vehicle’s owners manual. |
50 psi |
Section Width
Section WidthA tire's section width (also called "cross section width") is the measurement of the tire's width from its inner sidewall to its outer sidewall (excluding any protective ribs, decorations or raised letters) at the widest point. |
