What means Number In Your Tires

All tires have detailed information about the type, size, including the week and the year of issue. Those who understand this information would make the right choice of tires for his vehicle. The most accurate way to understand this is to select a sample of tires and see.

Below is a guide to the number of a tire. For example, try to examine the following numbers: 175 / 70R13 82H. The first 175 numbers refer to the width in millimeters, the distance is measured from side to side. usually if greater the number the greater the width of the tire. Number 70 said the aspect ratio (ratio aspact) tires or tire height compared to the width of the tire.

In the example, the tire height adalag 70% of the width of the tire. Usually tire with an aspect ratio of 55 and below are classified as low-profile tires. Performance low profile tires provide better overall handling even the aspect of comfort may be affected slightly.

The letter "R" refers to the construction of radial tires and car tires use radial construction 20 years ago. Radial construction tires do not have tubes and provide better performance. The number 13 refers to the diameter (diameter) to allow the tire rims mounted on the rim. If you want to change the tire with a larger diameter, you also need to change the rim to the same diameter.

Number 82 represents the index's ability to transport heavy tire. To find the maximum weight represents the number "82" to refer to the chart "heavy material transport capacity index" set at the international level. for example, the number 82 means the tire can carry a maximum weight of 475 kilograms. Refers to the maximum weight of each tire, we need to multiply by 4 to obtain the weight capacity of the vehicle. (example: 475 x 4 = 1900 kg)

The letter "H" which is the last state the maximum speed for a tire designed. H speed in this instance means that the tires can reach and maintain speeds as far as 210 km / h. Below is a list of the maximum speed charts as dilambang by each letter of the alphabet.

S-180 km / h
T-190 km / h
U-200 km / h
H-210 km / h
V-240 km / h
Z-hadlaju exceed 240 km / h
W-270 km / h
Y-300 km / h
The tires have the ability to overcome the speed of 270 km / h, the letters ZR will be used.
