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...
ABS (Anti-Lock Brake), Traction Control and Vehicle Stability Systems While anti-lock brakes, traction control, and vehicle stability systems help make it easier to utilize your tire's full potential, none of these systems actually provides more traction. These systems are only capable of...
Because winter tires typically have very aggressive tread designs they are more susceptible to the irregular wear that can be caused by suspension misalignment (or worn parts). Of the three normal alignment adjustments (caster, camber and toe) the camber and toe settings are the most important...
But Do I Really Need Winter Tires? Won't All-Season Tires Work Just Fine? Why Four Winter Tires? What If My Car Has Traction Control? What If My Car Has ABS Brakes? What If My Car Has Front-Wheel Drive? What If My Car Has All-Wheel Drive? Isn't It Better To Stay Off the Roads If It's...
Severe weather makes driving treacherous. Snow, ice, freezing rain, fog and even the winter sun all conspire to make winter driving more difficult and dangerous. With a little planning and a little training, this winter doesn't have to be a "white knuckle" winter for you. The two phenomenon...
Traction... Engineers have spent many hours designing systems for cars that give better control through ABS and traction-control, but these systems do not improve or create traction, they limit the performance of your vehicle to the traction provided by your tires. When you switch to boots to...
Whenever installing winter tires, drivers should recognize that the personality and handling traits of winter tires will feel different than the summer or all-season tires being replaced. Since winter tires are dedicated to providing more traction in snow and on ice, extra care should be taken...
Using the Hunter TC3500 mounting machine, optimal matching of the tire alignment relative to the wheel can be done with higher accuracy and help to eliminate vibration problems. The Hunter GSP9700 Road Force measurement balancer road tests the mounted tire and wheel to effectively measure...
Large diameter wheels and wide, low profile tires go together and show up everywhere from America's new car showrooms to its roads, tracks and trails. So whether the vehicle came from the assembly line or was upgraded after it was delivered, Plus Sizing (also called "Inch-Up" sizing in other...
Brake Caliper Profile - The shape and size of the brake calipers must fit within the design and shape of the wheel. It may seem obvious, but a wheel is comprised of a hub, spokes and rim. These parts work together to...
One of the last sights drivers want to see when they are getting ready to drive their vehicle is a flat tire. They realize that in addition to the immediate inconvenience of having to install their spare tire, they will have to get the punctured tire repaired. And if their tire is a steel...
While the Tire Rack tries to keep tire costs as low as possible, price is often a consideration when purchasing tires. Even with high fuel costs, it seems less agonizing to fill the tank with fuel than invest in a set of new tires. Why is it that the price of fuel seems relatively inexpensive...
Your tires support the weight of your vehicle, right? Well they don't! It's the air pressure inside them that actually supports the weight. Maintaining sufficient air pressure is required if your tires are to provide all of the handling, traction and durability of which they are capable....
