We've been helping people find the right tires, wheels and performance parts since 1979. If you're looking for the best and most accurate information on all things tires, you've come to the right place.
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 term "blowout" is generally used by drivers to describe a bursting tire accompanied by a rapid loss of air pressure. While one might assume that all blowouts are caused by too much internal pressure bursting a weak spot in the tire, the main reason for them is just the opposite. Most...
Tires are manufactured by assembling components made of rubber, fabric cord and steel wire that are cured together in a mold. Under intense heat and pressure during the curing process, the rubber reaches a near liquid state before vulcanization takes place finalizing the tire's exact size,...
The contact patch of a tire that’s inflated with pressurized air is also called its tread footprint. The contact patch is the result of the vehicle’s weight pressing its round tires against the road, requiring their treads to conform to relatively flat surfaces. A tire’s...
Though tires may look simple on the outside, they are actually complex laminate structures made up of over 100 individual parts. The individual parts of a tire include steel, textiles and multiple rubber compounds, and they must all work together to achieve many, often conflicting, performance...
Regardless of its size, every tire's load capacity, durability, traction and handling is dependent on using the right inflation pressure for the application. Since both too little and too much inflation pressure sacrifices some of the tires' performance, maintaining the "right" inflation...
Most drivers realize that tire load capacity is determined by tire size and inflation pressure. Larger tires and higher inflation pressures provide more load capacity, while smaller tires and lower tire pressures provide less. An under-inflated tire will tend to wear the shoulder areas of the...
Most drivers realize that tire load capacity is determined by tire size and inflation pressure. Larger tires and higher inflation pressures provide more load capacity, while smaller tires and lower tire pressures provide less. Correctly inflated tires receive appropriate support from the...
Advantages of Correct Tire InflationMaintaining correct tire inflation pressure helps optimize tire performance and fuel economy. Correct tire inflation pressure allows drivers to experience tire comfort, durability and performance designed to match the needs of their vehicles. Tire deflection...
While it is simple to place a Lincoln penny in the tread groove of a worn tire and use Abe's likeness as a guide, we don't think Honest Abe knows what's best for today's drivers. The Lincoln penny tread depth test has been touted for years to be a suitable method of determining when it's time...
Four-wheel drive and all-wheel drive vehicles are equipped with differentials and/or viscous couplings that are designed to allow momentary differences in wheel speeds when the vehicle turns a corner or temporarily spins a tire. However, if the differentials or viscous couplings are forced to...
In some states, vehicle inspection regulations require operating tire pressure monitoring sensors (TPMS) on every vehicle that came with TPMS as Original Equipment. If your state is not listed below, please check with local law enforcement officials to confirm restrictions in your area. We...
While today's P-metric passenger tire sizes have existed since the early 1980s, restoring classic muscle cars and pony cars has kept yesterday's numeric and alpha numeric tires from disappearing. This chart has been developed to help you determine their equivalent Euro-metric and P-metric tire...
