Marking of tires and disks

Each car owner is faced with the situation when it is necessary to choose new tires or wheels. In this case, you will be guided by the marking of tires. Due to this, the buyer will be able to easily understand the parameters of the disks and tires, as well as choose the tires that best suit your requirements.

To begin with, it is recommended to carefully read the manual for use, which will indicate the marking of tires and disks, which is recommended by the manufacturer. It should also be taken into account that the manual often indicates several recommended markings that can be used at the discretion of the car owner, depending on the following criteria:

1. The material of the disks is aluminum or iron. This criterion is taken into account, based on the condition that the aluminum disks have a somewhat larger width and radius.
2. Season of operation: winter or summer time.
3. The type of engine of your car and its power.

Of course, you can see the wheels already installed on the car. However, it is necessary to take into account the fact that marking tires may not be suitable for the comfortable use of your car. In this regard, many stores, including Internet resources, provide services for the selection of optimal tires.

For an example of notation, consider the size.

205/55 R16 94 H (tire marking)

The decryption begins on the first day, which Denotes the width of the tire in millimeters. The second figure shows the ratio of the height of the existing profile to the width of the tire. This indicator is often referred to as a "profile". If we consider the case when there are two or more tires with the same data on their width, but with different profile values, then one can observe the regularity: the higher the profile height, the higher, in the literal sense of the word, the tire becomes.

Proceeding from the fact that this parameter is a relative value, when choosing a rubber, it must be remembered that with incorrect selection, not only the width of the tire under consideration will change, but its height, which in many cases is simply unacceptable. If the tire marking does not provide information about this parameter, it is accepted by default from 80% to 82%, and the tire is called full-profile. This type is used in light trucks and minibuses.

The tire marking also includes the letter "R", which is responsible for the designation of a tire with a radial cord.

The number behind is the diameter of the tire, given in inches. This value represents the so-called landing diameter of the tire.

The symbol "H" at the end of the designation is responsible for the permissible speed index that a car with these tires can develop.

Often, the marking of tires includes color marks: yellow, red, etc. They show the places with the least and greatest load on the wheel.

The tire can be marked in the form of a white stamp with a number that corresponds to the number of the inspector who conducted the final inspection of the tire at the factory. Whole strips are applied to quickly and easily search products in the manufacturer's warehouses.
