What you need to know when buying new tires


What you need to know when buying new tiresIf your vehicle is due for new tires you better find your way to the tire store before you suffer a blowout or notice a lack of traction. Once at the store the tire salespeople may begin to discuss your needs regarding tires and then give you your best options. They may use a few words that you're not familiar with in regard to tires, so use this cheat sheet so you can follow along perfectly in the conversation. However, you should always ask questions regarding your new tires, should you have any.

Tread lug

The tread lug is commonly referred to as just tread. It is the part that actually contacts the roadway, providing much needed traction to keep your car under control. The part of the tread lug that is contacting the ground at any given time is called the footprint.

Tread Void

The gaps between the raised sections of tire tread is referred to as the tread void. These are the areas that allow tires to pass through water, snow, mud and other road debris in order to without losing traction or hydroplaning. Tires with high tread voids will do better in slippery conditions, on the contrary, those with a lower amount of tread void are best suited for dry conditions.

Tire Shoulder

A tire's shoulder is where the tread lug transitions to the rubber that makes up the tire's sidewalls.


The inside edge of a tire that contacts the wheel rim is known as the bead. It is usually made of a strong rubber that's reinforced with steel wiring to keep it tight against the rims as the tire rotates while driving.


Tires are composed of several layers of rubber called plys. Tires are made of various amounts of plys. The number of plys can alter the type of performance and affect vehicle handling.

Wear Bar

Tires are equipped with a wear bar in order to help a driver determine if they're due for new rubber. The wear bar consists of lower pieces of rubber within the tread void and as the tread lug wears it will become flush with this wear bar. When this happens it means you're definitely due for new tires!
