Truck Tire Basics

While much attention is justifiably given to engine, brakes, and suspension when assessing a vehicle's dynamics, the most crucial safety and performance component is the tires. The rubber at all four corners is the only part of the vehicle that touches the ground, with four palm-sized contact patches depended on for traction. All the other components work to maximize their relationship with the tires.

With a two- or even three-ton vehicle, not counting possible cargo or trailer, fitting the right tires for the job is important, with several options usually available from the factory and even more from the aftermarket industry.

While tires for pickups and sport/utility vehicles can be sliced into numerous niches, there are four main categories. The most dramatic group, Off-Road, features tires designed for rugged adventurers, wranglers, and rovers who haul serious loads down long trails through the wilderness in their 4x4s, trekking and scrambling across all type of terrain-mud, snow, rock, desert, and timber.

All-Terrain tires are engineered for solid on-road performance with added grip for dirt, snow, and wet surfaces, making them an appealing choice for occasional light-duty off-pavement excursions.

Performance tires are engineered to help SUVs and trucks achieve sport-sedan-like pavement traction, enabling maximum acceleration, braking, and handling, either from a premium vehicle or from a modified one.

Then there are highway tires for the rest of us, the tens of millions who settle for just projecting an image of freedom and excitement with a rugged, versatile vehicle that will never be pushed to its mechanical limits. Most consumers want a good pavement tire, with excellent wet-weather performance, good longevity, and low noise. No matter which group you're in-or you think you're in-we'll help you start your search for tires in the right direction.
