What brand is radial tire?
2 Answers
radial refers to radial tires, with the international code R, and is not a brand. Radial tires: Radial tires were patented by Michelin in 1946. They are composed of two or three layers of steel belts cross-placed and adhered to the cord body. The carcass cords of radial tires run from one bead to the other, similar to the Earth's meridians, hence the name radial tires. Currently, most passenger car tires are radial tires. Advantages: Radial tires have many advantages over bias-ply tires, which is why they are the current standard in tire construction. Their advantages include: larger contact area, better adhesion, less tread slippage, lower unit pressure on the ground, lower rolling resistance, longer service life, thicker tread with a hard belt layer, and better puncture resistance.
At first I thought 'radial' was a brand name when I saw this question, but after checking I realized it's actually the technical term for radial tires. These tires have a special internal structure where the cords radiate from the wheel hub center to the tread, just like bicycle wheel spokes. The biggest advantage of this design is that it makes tires more wear-resistant and provides better directional stability while driving. Nowadays, almost all passenger cars come standard with this type of tire. If you look closely at the tire sidewall when changing tires, you'll definitely find the 'radial' marking - it's not related to brands like Michelin or Bridgestone, just a technical label. By the way, these tires also have an 'R' letter marking on the sidewall, which also refers to this structure.
