Terms to Know When Buying New Tires

Terms to Know When Buying New TiresIf your car or truck is ready for new tires it's likely because you noticed that the tread has worn thin, the rubber is cracking or it has become harder to stop your car because of the loose grip the tires have on the roadway. Buying tires can seem difficult, especially if the technician is using tire terms you just don't understand. In order to make the tire buying process easier here is a list of terms that are important to know, so you can talk shop with your tire tech to ensure you get the right rubber for your ride.

Tread lug

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

Tread Void

The gaps between the raised section of tire tread is referred to as the tread void. These are the areas that allow tires to pass over water, snow, mud and other road debris in order to maintain traction and prevent dangerous hydroplaning. Tires with high tread void will do better in slippery conditions, on the contrary, those with lower amounts of tread void are good for dry conditions.


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


The inner edge of a tire that contacts the metal wheel rim is referred to as the bead. It is generally made of a strong rubber that's reinforced with steel wiring to keep it tight against the wheel rims as the tire rotates.


Tires are composed of layers of rubber called plys. Tires are made of various amounts of plys, depending on the type of performance they will be expected to be performing. The amount of plys on a tire can also affect vehicle handling.

Wear Bar

Tires are equipped with what is referred to as a wear bar in order to help a driver determine if they are due for new tires. 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!
