Motorcycle tires are the most easily overlooked parts

Motorcycle tires are the most easily overlooked parts, which directly affect the vehicle's handling performance, driving comfort, driving quality and vehicle safety.

Structure of the tire There are two basic structures for the tire: the skew line tire and the radial tire. According to safety common sense, most cruise motorcycles use skewed structural tires, while most sports motorcycles use radial tires; spoke wheel tires require inner tubes, while cast wheel tires do not require inner tubes; The structural tire has a rounder contour and a higher sidewall of the tire; while the radial tire has a flater profile and a shorter sidewall. The carcass ply below the crown of the oblique line tire is formed by laminating a plurality of layers of nylon and rayon, and the different plies are stretched at opposite angles to form an X-shape - the reason for the design of the skew line structure tire.


Some tires add a layer of belt to the top of the ply that runs along the tire's rolling direction. During the rolling process of the tire, a small part of its contact with the ground will flatten in an instant, and then rebound back to its original state, which is called the running surface - it repeats flattening and rebounds during the tire running. The change to the original state is changed, and the heat generated by the continuous flexural deformation of the tire is very favorable for the grip performance of the tire, but if the excessive flexural deformation causes too much heat, the tire grip performance is lowered. And accelerate tire damage.

The direction of the radial tire ply is perpendicular to the rolling direction of the tire, which is advantageous for reducing the heat generated by the deflection of the tire so that the temperature of the tire is low during operation; since the sidewall of the radial tire is more susceptible to flexural deformation, the contour of the tire is shorter. The low profile structure of radial tires indicates that it can carry more loads, which is more suitable for cruise motorcycles that require heavy loads of passengers or luggage; while skew tires are more suitable for cruise motorcycle suspension and cornering performance. For this reason, you must confirm that it is suitable for your motorcycle before purchasing a motorcycle tire.

For oblique line tires and radial tires, the tread groove design differs depending on the potential use of the tire. The groove design on the tire crown is mainly used to discharge water from the running surface of the tire. The more grooves in the crown pattern, the better the tire drainage performance. Usually, cruisers and coaches need to travel frequently in rainwater, so their tires need to have high drainage performance; while sports motorcycles are not designed for driving in the rain, the fewer grooves on the tire crown pattern, The more rubber the tire is in contact with the ground, the more traction the tire can get on dry ground.
