What is the standard for car tires?
Car tires according to different carcass structure can be divided into pneumatic tires and solid tires. The vast majority of modern cars use pneumatic tires. According to the level of air pressure in the tire, pneumatic tires can be divided into high-pressure tire, low-pressure tire and ultra-low pressure tire three. Various types of cars generally use low-pressure tire. Pneumatic tires according to the composition of different structures, but also divided into tube tires and tubeless tire two. Passenger cars are generally used tire tires within the tire ply and buffer layer arranged in different ways, the tire can be divided into two kinds of radial tires and bias tires. The car is generally used in radial tires. Tire side are marked.
Tire type and specification: International standard tire code, expressed in millimeters as a percentage of section height and flatness, followed by: tire type code, rim diameter (inch), load index (permitting bearing quality code), promise With speed code. For example: 175 / 70R 14 77H 175 represents the tire width is 175MM, 70 means that the flatness of the tire cross section is 70%, that is, the cross section height is 70% of the width, the rim diameter is 14 inches, the load index 77, the allowable vehicle speed is H level
The tires are rounded elastomeric rubber products that are grounded on various vehicles or mechanically assembled. Usually installed on a metal rim, can support the body, cushion the impact of the outside world, to achieve contact with the road and to ensure that the vehicle's tire is often used in complex and harsh conditions, it is driving a variety of deformation, load, High and low temperature effect, it must have a high bearing capacity, traction performance, buffer performance. At the same time, also requires high wear resistance and flex resistance, as well as low rolling resistance and heat generation. Half of the world's consumption of rubber for tire production, visible tire consumption of rubber capacity.
