A tire's most important job is to carry the load required of it, and the load range/ply rating branded on the tire's sidewall indicates how much load the tire is designed to carry (at a specific pressure). Whenever changing tire sizes or from one tire type to another, it's important to ensure...
A load index is an assigned numerical value that signifies a tire's maximum load carrying capacity. They're useful to help compare load carrying capacity of different-sized tires, and as you might expect, the higher the tire's load index number, the greater its load carrying capacity. Using the...
The purposes of the Tire and Rim Association, Inc., include the establishment of interchangeability standards for tires, rims and allied parts for the guidance of manufacturers of such products, designers and manufacturers of motor vehicles, aircraft and other wheeled vehicles and equipment,...

Experience indicates that searching by wheel size, offset and/or bolt pattern alone are not specific enough criteria to ensure an exact fitment. Attention to detail prevents vibration, wheel/tire interference and unbalanced handling. A vehicle's critical components are measured with...
Vehicle manufacturers are required to maintain an average fuel economy for the fleet of new vehicles they sell each year In the United States. Vehicle manufacturers must pay a penalty if their annual vehicle fleet uses too much fuel. The Corporate Average Fuel Economy (CAFE) identifies the...
