How Tire Work & How To Maintain Them

600 × 300
A lot is riding on your tires. It’s important to understand how tires work and how to properly maintain them. Continue reading to explore the parts of a tire (there are more than you’d think).

Tires are made up of many different parts, and it’s important to understand how they work.

A. Tire Belts
Rubber-coated layers of steel, fiberglass, rayon, and other materials located between the tread and plies, crisscrossing at angles, hold the plies in place. Belts provide resistance to punctures and help treads stay flat and in contact with the road.

B. Tire Sipes
Sipes are special treads within the tread that improve traction on wet, dirty, sandy, or snowy road surfaces.

C. Tire Tread
The portion of the tire that comes in contact with the road.

D. Tire Grooves
The spaces between two adjacent tread ribs are also called tread grooves. These allow water to escape effectively.

E. Tire Shoulder
The outer edge of the tread that wraps into the sidewall area.

F. Tire Sidewall
The sidewall of the tire protects cord plies and features tire markings and information such as tire size and type.

G. Tire Inner Liner
This is the innermost layer of a tubeless tire that prevents air from penetrating the tire. H. Tire Bead A rubber-coated loop of high-strength steel cable that allows a tire to stay "seated" on a rim. I. Tire Body Plies This is the tire itself, made up of several layers of plies. Plies, like polyester cord, run perpendicular to the tire's tread and are coated with rubber to help bond with other plies and belts to seal in air. Plies give tires strength and resistance to road damage.
