This is a set of Tire O-Rings. They are specially designed to be used to install most drift tires on most rims. They offer them in 2 sizes, thick and thin.

The thin ones are by far the more popular choice. Sometimes, certain rim companies product rims that are slightly smaller in tolerances and require the thicker O-Rings to keep the tire firmly on.

Most people have a variety of both in case this happens.

Tire O-Ring Packs all contain 8 O-Rings.

You use 1 O-Ring per rim. The O-Ring prevents the tire from slipping in place, or falling off.

Sold as packs of 8 (2 full sets)
