GENERAL INFORMATION

Arrangement of marking of the tire

Tires and rims (on disk wheels) are important elements of a design of the car.

Installation and repair of tires demands the special tool and professional skills. Only professionals have to perform these works.

For safety reasons the movements, it is necessary to change whenever possible tires not separately, and at least, on axes. Less worn-out tires should be put always on forward wheels.

On all four wheels it is necessary to have only radial tires of the same design, the identical size (with an identical length of a circle) and whenever possible identical execution of a profile of the tire. In the presence of the drawing of the protector defining the direction of rotation of tires on the side surface of the tire there are shooters indexes (see rice. Arrangement of the arrow specifying the direction of rotation of the tire). In this case it is necessary to observe the direction of rotation of the tire strictly. At the same time optimum road performance of the tire, its coupling with a wet paving are provided and the wear and noise created by the tire decrease. If when replacing of the punched wheel, the tire with rotation against the set, then its ispolzov ny in this mode temporarily is installed has to be short-term.

On the all-wheel drive car, besides, all tires have to be identical model of the same manufacturer.

Otherwise the visko-coupling because of the arising difference in the frequency of rotation of wheels of both axes it is undesirable will lift the draft share falling on a back axis. It can lead to breakage.

Various depth of the drawing of a protector of tires of forward and back wheels, for example, as a result of wear, is not so important. However it is recommended to install tires with a bigger depth of the drawing of a protector on forward wheels – if tires of forward wheels are worn-out more, than tires of back wheels, they have the smaller length of a circle and rotate therefore quicker. Therefore there is additional tension in transmission, and tires wear out quicker.

If the tire of a spare wheel on the execution differs from other tires of the car (for example, winter or wide-profile), then such spare wheel has to be used only quickly in case of failure of one of tires of the car and at a sootvetstvo of the yushchy increased care of driving. Instead of such wheel follows, as soon as possible again to establish a former wheel.

Never put on the car the second-hand tire if it is unknown where and as it worked before.

Knowledge of marking of tires helps at their choice (see rice. Arrangement of marking of the tire). Radial tires have on a tire sidewall the following marking, for example:

195/65 R 15 91 T

195 – width of a profile of the tire, mm

65 – tire height relation to % profile width

R – an arrangement of threads of a cord of a framework – alphabetic reference for the radial tire

15 – diameter of a rim of a disk, inch

91 – index of admissible loading capacity

T – a speed index

Speed index
Maximum speed
Q
160 km/h
S
180 km/h
T
190 km/h
H
210 km/h
V
240 km/h
W
270 km/h

Date of issue is specified also on a tire sidewall (in some cases only on the internal surface of the tire).

DOT CUL UM8-507 TUBELESS

DOT – manufacturer

CU – code designation of the manufacturer

L2 – the tire size

UM8 – tire type

507 – date of production (the 50th week 1997)

TUBELESS – the tubeless tire (TUBETYPE - chamber).

Designation of rims: 6J x 15 are deciphered as follows:

6J – disk width in inches;

J – height of an onboard edge of a disk;

x – a deep disk;

15 – landing diameter of a disk in inches.
