PCR tyre moulds are named because the angle between the cord layer and the center of the tread is similar to the meridian on the earth, usually 90° or close to 90°. This tyre mould is widely used in most civilian cars on the market today.
PCR tyres are not the only type of tires. There are also many types such as TBR radial truck tires, TBB bias truck tires, OTR tires for construction machinery, LTR light truck radial tyres, and LTB light truck bias tyres. Their names reflect their respective usage environments and characteristics.
Different types of tire molds have their own advantages in performance, durability and safety. Therefore, when choosing a tyre, it is necessary to make a comprehensive consideration based on the model, usage conditions and personal needs. The advantages of this type of tire mold are obvious: it has strong wear resistance and puncture resistance, good buffering effect during driving, and excellent temperature control. At the same time, it has good rigidity and safety, can extend service life and save fuel. It has a large ground contact area, strong adhesion, small slippage during driving, small pressure on the road surface, and small rotation resistance, so it is more durable.
The three or four longitudinal grooves on the tire surface are called water guide grooves, which are mainly used for drainage. Because when the tire is driving on the rainy road at high speed, a thin layer of water film will be formed between the tire and the road surface. In order to increase the contact between the tire and the ground, several water guide grooves will be set in the longitudinal direction of the tire to effectively drain the tire.
The water guide groove is mainly used for drainage. If there is no water guide groove, there will be a layer of water film between the tire surface and the road surface, which affects the friction. The transverse pattern on the side of the water guide groove is generally used to assist in cutting off the water film. This is mainly designed according to the width of the tire and the width of the groove. Some tires are very narrow and three grooves can meet the requirements. Some tires are very wide and require 5 grooves. Some grooves are wide, and the drainage of three grooves is equivalent to the normal four grooves. So you don't have to worry about this problem.
These are all issues that engineers consider when designing tire patterns. You just need to choose the tire according to your tire model. The water guide groove is mainly used for drainage.

In general, PCR tyre moulds are not only the representative of modern tire technology, but also more comprehensively improve the driving experience and vehicle performance. In daily driving or long-distance travel, it is a key factor in ensuring safety, comfort and economy.
