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...
Why do we change our tires and wheels? Aside from necessity, most of us do it for performance, comfort and style. But to be sure our tires are performing properly and that we're rolling comfortably and in style, we'll need to correctly install our new tires and wheels. Here's a few tips from us...

For wheel designs that require special tire mounting attention. While size designations for tires (i.e., 245/40R18) and wheels (18x8) confirm matching (18-inch) bead seat diameters, measuring a wheel's overall diameter from the top edge of one flange to the other 180-degrees away will reveal...

Sidewall Indentations / UndulationsFig. A: Vertical indentation on sidewall from rim to tread. A common byproduct of radial tire construction, sidewall indentations/undulations are more noticeable in tires with taller sidewalls or operate at higher inflation pressures. Fortunately sidewall...
For handling-oriented track & competition fitments, Tire Rack recommends mounting tires on the widest rim width approved by the tire manufacturer (and permitted by competition class rules). However, we also recognize that rules for stock, spec, or other autocross/racing classes often restrict...
Much like your foot can sometimes fit in a half size up or down shoe, tires have a range of rim widths they can be mounted on while still performing as designed. Likewise, similarly to how a person typically knows their "shoe size," tires have a measuring rim width from which the tire's specs...
The offset of a wheel is the distance from its hub mounting surface to the centerline of the wheel. The offset can be one of three types (measured in millimeters).* "The offset of a wheel is the distance from its hub mounting surface to the centerline of the wheel." Zero Offset The hub...
