Structure of tires There are two basic structures of tires: bias tires and radial tires. According to safety common sense, most cruise motorcycles use diagonal structure tires, while most sports motorcycles use radial structure tires; spoked wheel tires need to have inner tubes, while cast hub wheel tires do not need to use inner tubes; Structural tires have a rounder profile and taller tire sidewalls, while radial tires have a flatter profile and shorter tire sidewalls. The carcass ply under the crown of a biased tire is made of multiple layers of nylon and rayon.
Some tires have an additional belt layer on top of the ply that runs in the direction the tire rolls. As the tire rolls, a small portion of it in contact with the ground flattens for an instant, and then bounces back to its original state, called the running surface - it repeatedly flattens and bounces back as the tire travels The change to return to the original state, and the heat generated by the continuous flexural deformation of the tire is very beneficial to the tire's grip performance, but if the excessive flexural deformation causes excessive heat generation, it will reduce the tire's grip performance and accelerated tire damage. The direction of the ply of radial tires is perpendicular to the rolling direction of the tire, which is beneficial to reduce the heat generated by the deflection of the tire, so that the temperature of the tire is lower during operation; since the sidewall of the radial tire is more prone to deflection and deformation, the tire profile is shorter. The low profile structure of radial tires means that they can carry more loads, and they are more suitable for cruise motorcycles that need to load heavy passengers or luggage; while bias tires are more suitable for cruise motorcycles. Suspension and cornering performance requirements. With this in mind, be sure to check whether motorcycle tires are suitable for use on your motorcycle before purchasing a motorcycle tire. For bias and radial tires, the groove design of the crown pattern varies according to the potential use of the tire, and the groove design on the tire crown is mainly used to drain water from the tire running surface. The more grooves in the crown pattern, the better the drainage performance of the tire. Usually cruise cars and touring cars need to be driven in the rain frequently, so their tires need to have high drainage performance; while sports motorcycles are not designed for driving in the rain, so the fewer grooves on the tread pattern on the tire crown, The more rubber that the tire has in contact with the ground, the more traction the tire has on dry ground.
