Radial is not a tire brand. It refers to radial tires and represents a tire structure. The international code is R, commonly known as "steel wire tires".
Patented by Michelin in 1946, radial tires are composed of two or three layers of steel wire rings placed crosswise and attached to the cord carcass. Radial tire carcass cords The bead on one side is connected to the bead on the other side, much like the radials of the earth, so tires with this structure are called radial tires.
The advantages are:
1. Large ground contact area, good adhesion, small tread slippage, and small unit pressure on the ground, so the rolling resistance is small and the service life is longer. .
2. The tire crown is thick and has a hard belt layer, which is not easy to puncture.
3. It is not easy to deform when driving and can reduce fuel consumption.
4. Because the number of cord layers is small and the sidewall is thin, it has large radial elasticity, good buffering performance and large load capacity.
5. It has good heat dissipation performance and can adapt to high temperatures and high-speed driving.
