The tyre is a ring shaped elastic rubber product which is assembled on various vehicles or machinery. Usually installed on the metal rim, to support the body, cushion the impact of the outside world, to achieve contact with the road and to ensure the driving performance of the vehicle. Tires are often used in complex and harsh conditions, it is running under a variety of deformation, load, force and high low temperature effect, so it must have a high bearing performance, traction performance, buffer performance. At the same time, also requires high abrasion resistance and flex resistance, and low rolling resistance and heat build-up.
Tire structure classification
In accordance with the tire structure can be divided into bias tires, radial tire, the basic use of modern car radial tire, the code represented by R, and the bias tires D. The fundamental difference between radial tire and bias of fetal carcass is oblique, fetal the carcass is cross ply; and radial tire carcass is cross polymer multilayer materials, steel cord is its top layer by number of steel wires, can reduce the probability of tire punctured by a foreign body.
Tire pattern classification
Tire and road surface friction generated by contact patterns, including the general pattern, this pattern pattern and mixed pattern, the general pattern is suitable for use in hard surface, it is divided into the longitudinal and lateral pattern and aspect with pattern.
Cross country pattern is also called block pattern, feature is the pattern groove width and deep, the pattern block ground area is relatively small, grip, but the rolling resistance is big, it is not suitable for a long time in good hard road. Otherwise, will aggravate the tire wear, increase the fuel consumption, the car driving vibration is also more powerful.
Mixed pattern is a transitional pattern between common patterns and cross-country patterns. It is characterized in that the middle part of the tread is provided with a narrow pattern groove which is different from the direction or longitudinal direction, while the two sides are different in direction or transverse direction. This pattern matching to make the comprehensive performance of the mixed pattern, strong adaptability.
Tire specification parameters
In order to allow users to intuitively learn the configuration of the tire, the tire factory has included the parameters of the tire and the production date.
Such as a tire specifications for 185/65/R1486H
185 - refers to the tire width of 185mm
65 - refers to the flat tire ratio, that is, the height of the section is 65%
R: refers to the tire radial tire (the tire inner radiation tire manufacturing mode)
14 - refers to the hub diameter is 14 inches
86 - refers to the load index 86, on behalf of the maximum load of the tire 530Kg, 4 tires is 530 x 4=2120Kg
H - refers to the speed level of 210 km / h
The load index of the tyre represents the nominal load bearing capacity of a single tire. In general, the small car is equipped with 4 tires, and the corresponding nominal load bearing weight should be multiplied by 4. The following is the load index actually represents the nominal carrying weight, the unit is Kg.
In addition to the load index, the tire has a speed rating, to meet the needs of different speed models, the speed rating is still rated speed.
From the table we see that the maximum speed of the tire can be up to 300Km/h, while the general use of ordinary cars U, H, V grade tires, the maximum speed of up to 200Km/h, 210Km/h, 240Km/h.
The production date of the tire is usually represented by four digits, the first two of which represent the number of production date and the following two representative years, such as 3512 represent the tire production date for the thirty-fifth week of 2012 (August).
Tire purchase skills
Replacement of tires to give priority to the original factory tires, the original tire is the most able to coordinate with the car speed and the maximum load of the car, so the theory is the most suitable for the use of the vehicle.
Second, pay attention to the pattern of tires, car tires on the pattern, in addition to the appearance of the effect, the performance of the tire also have a great impact. Often in Shenzhen car, should choose those drainage good tyres, such as patches of regular pattern; to off-road and long-distance car, you can choose bulk pattern.
Finally, if you are not satisfied with the original vehicle controllability, could be lower than the flat tire, on many models, one of the most effective methods to improve the appearance of the vehicle and steering performance is low than the flat tire replacement. Each style tires have their specific function, so in the choice of tires, should ask what styles of tire how kind of driving habits, so that the car driving is safer, spend the money on the tire is also worth.
Tire installation
Please use the standard has 1 wheels, the deformation and damage of the wheels do not use.
2 rim and tire assembly, please clean the rim and tire, do not have debris left in the interior.
3, rim and tire assembly before. Can use rubber lubricant or soapy water wipe the bead rim flange, do not use oily lubricant.
4 rim and tire assembly should be paid attention to when the chimeric, do not use the pressure above the normal range of installation force, in order to avoid danger.
5 rim and tire assembly by tire line specialized personnel to operate, please do not mix.
6 installation of the tire also need to pay attention to the inner and outer side of the tire, generally speaking with "Outside", "production date", "DOT" marking the surface are representative of the outside.
6 tire pressure must be in accordance with the user manual or logo on the body to perform, to avoid the occurrence of high pressure tire etc..
