Your Guide To Buying Tires

Posted on: 10 November 2015

Tires are one of the most important purchases you'll make. Your safety depends on their quality and reliability. There are some major differences among the various classes of tires. Use this guide to make the best selection for your driving habits and weather conditions.

Heat Dispersal

Heat buildup is a major contributor to blowouts. Air inside the tire expands as it gets hotter, and finally the force of expansion causes the tire to explode. Some tires are designed to disperse heat more quickly than others. Additionally, if you should buy retreads, excessive heat can cause the tread to separate.

The industry assigns a heat dispersal rating to each tire design. The best rating is A. The other two grades are B and C. If you drive on the highway every day for work, then "A" is the safest choice.

Tread Design

The design of a tire's tread has a direct impact on how well you control the car in a turn, on wet roads, or when you need to stop quickly. The three styles are symmetrical, asymmetrical, and directional.

The tread face is divided into "inside" and "outside", with outside being the side that is mounted toward the hubcap. Symmetrical designs mimic each other on the inside and outside halves of the tread. For example, if the outside half has a row of zigzag lines in the middle plus outward facing straight lines on the edge, the inside half of the tread will have the same pattern. This is the most common pattern for all-season tires. It provides good control in most situations.

Asymmetrical treads having a varying design across the tire. They are commonly referred to as snow tires. This tread pattern resists becoming packed with snow so you can maintain good traction. The smaller design on the inside half allows more of the tread to make contact with the road when you are turning.

Directional treads are designed to resist hydroplaning during highway driving. The V-shaped design in the center merges with sideways treads at the edge to pass water back to the road more quickly than the other two designs.

Weight Load

Tires are rated on how much weight they can support. For example, if you have a large SUV or pickup truck, you must choose tires that can support the higher weight. A tire designed for a small vehicle will go flat or blowout if subjected to the weight of a larger vehicle. Always select tires designed to handle the weight of your car or truck.
