Every car owner is faced with a situation where it is necessary to choose new tires or wheels. In this case, the tire marking will help you navigate. Thanks to this, the buyer will be able to easily understand the parameters of wheels and tires, as well as choose the most suitable tires for your requirements.
To begin with, it is recommended to carefully read the instructions for use, which will indicate the marking of tires and wheels, which is recommended by the manufacturer. It should also be taken into account that the manual often contains several recommended markings that can be used at the discretion of the car owner, depending on the following criteria:
- Material of installed disks: aluminum or iron. This criterion is taken into account based on the condition that aluminum wheels have a slightly larger width and radius.
- Operating season: winter or summer time.
- Your car's engine type and power.
Of course, you can look at the wheels already installed on the car. However, it is necessary to take into account the fact that tire markings may not be suitable for the comfortable use of your car. In this regard, many stores, including online resources,provide services for the selection of optimal tires.
For an example of designations, consider the standard size.
205/55 R16 94 N (tyre marking)
Decryption starts with the first number, which indicates the width of the tire in millimeters. The second digit 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 we can observe a pattern: the greater the profile height, the higher, in the truest sense of the word, the tire becomes.
Based on the fact that this parameter is a relative value, when choosing rubber, you should definitely remember that if the selection is incorrect, not only the width of the tire in question will change, but also its height, which in many cases is simply unacceptable. If the tire marking does not provide information about this parameter, it is taken from 80% to 82% by default, and the tire is called full profile. A similar type is used in light trucks and vans.
Tire markings also include the letter "R", which is responsible for the designation of a tire with a radial ply.
The number behind is the tire diameter given in inches. This value represents the so-called fit diameter of the tire.
The "H" symbol at the end of the designation is responsible for the permissible speed index that a car can develop with these tires.
Often, tire markings include color marks: yellow, red, etc. They show the places with the least and the most load on the wheel.
The tire may be marked with a white stamp with a number that corresponds to the number of the inspector who carried out the final inspection of the tire at the factory. Colored stripes are applied for quick and easy product retrieval in the manufacturer's warehouses.

Year of the tire. Deciphering the marking of tires
If it is necessary to replace old tires with new ones, all motorists have the question of how to find out their year of manufacture. It can be read on the rim of tires, because each manufacturer must indicate the date of manufacture without fail. But there are no uniform standards, so sometimes it can be difficult to do. You can read about where on the tires you can find the year of manufacture, about their service life and recommended operating conditions in this article
Three-wheeled scooter: two wheels in front or two wheels in back
Ten years ago, unusual motor scooters suddenly rolled out onto the roads. The three-wheeled scooter had a truly revolutionary design, where two wheels were located not in the back, but in front. Who came up with this first is unknown. But the first models, after the decline of surging emotions, did not cause much enthusiasm among consumers. New attempts are on the way. The same scooters look much more familiar, but, as expected, with two wheels at the back. Let's talk about some and other models in order
