What brand is radial tire?
2 Answers
radial refers to radial tires, internationally coded as R, and is not a brand. Radial tires were patented by Michelin in 1946. They are composed of two or three layers of steel belts cross-placed and bonded to the cord body. The carcass cords of radial tires run from one bead to another, resembling the earth's meridians, hence the name "radial tires." Currently, most passenger car tires are radial tires. Compared to bias-ply tires, radial tires have many advantages, which is why they dominate modern tire structures. Their benefits include: larger contact area, better adhesion, less tread slippage, lower unit pressure on the ground, reduced rolling resistance, longer service life, thicker tread with a rigid belt layer, and greater resistance to punctures.
I remember being confused about this when I bought my car. Radial isn't a tire brand - it refers to the internal structure of a tire, meaning the cord plies are arranged vertically from the tire center in a radial pattern. This design is far superior to old bias-ply tires. With vertical cords, the tire deforms less, providing better grip, improved fuel efficiency. On long drives, I've clearly noticed reduced noise and longer lifespan. Brands like Michelin or Bridgestone all mark their tires as radial, indicating high-performance types - nearly all modern vehicles use this construction now. When replacing tires, make sure to choose the right model and avoid bias-ply ones as they handle poorly. Also, regularly checking tire pressure helps extend tire life.
