Dimensions
in the international standard, a tire size generally consists of six parts, including tire section width, flat ratio, type code of the tire, rim diameter, load index, and speed level (allowable vehicle speed code).
There are a common type of tire code X (high-pressure tires), R / Z (radial tire), a (low pressure tires), we usually seen in the car to are radial tires. Load index represents the ability of the tire is subjected to a load, the greater the value, the quality of the tire can carry greater. Load index and the corresponding bearer quality is as follows:
represents the highest level of speed limit of the vehicle speed exceeds the speed is likely to cause puncture. The higher the speed level, the higher the requirements for materials and design of the tire. As shown in the table below the maximum speed corresponding to the speed level code:
produce tires for vehicle performance and comfort, fuel consumption, tire noise, etc. will some influence. First, the width of the tire affects the vehicle’s fuel consumption to some extent. In the case of other factors constant, the wider the tire, the ground contact area becomes greater, thereby causing more heat loss, and therefore the fuel consumption is increased accordingly. The flatness ratio affects vehicle handling.

how to classify?
The structure according to the classification of the vehicle tire, then there are two kinds of bias tires and radial tires. Can be divided in accordance with another rib pattern tire, the lug of the tire, the tire tread mixed, off-road tire tread. butWe usually for some special tires are classified according to use features.
high-performance tires
in pursuit of ultimate driving pleasure, high-performance sports car owners tend to replace the converted stores a grip and better handling performance tires , such a tire is called high-performance tires. It uses the ordinary rubber tires different formulations, patterns, etc. have high tread design requirements, such as the Pilot Sport 3 and Michelin Pilot Super Sport.
The tire
The tire rubber is relatively soft, when the snow road has a better grip, the vehicle can be prevented from mounting a snow tire winter skidding under harsh conditions. Such tires usually with pictographic mountain and snowflake logo.
the tire mud
Dirt tire size is large, is not easy to can not get stuck in the mud, since the pattern of an open design, mud discharge can be quickly open. When the steering wheel may be utilized centrifugal force debris away from the tire surface to prevent clogging.
run-flat tires
A lot of people also known as “flat tires”, but the tire puncture just a small chance that not will not puncture. Runflat tire sidewall is thickened, with the tire deflated, the original shape of the tire can be maintained within a certain distance, to ensure that the driver can drive the vehicle to the nearest repair point.
