The numerous specifications on the tire, each represents what kind of meaning? automobile wheel trade fair to share with you:

A. Tire brand

Just like all commodities on the market, label and brand names are marked on the products, and tires are no exception, of course!

Generally speaking, a long string of English you do not understand, is the tire brand name, or model.

Two. Tire style/model

The tire factory will name and number its products for the convenience of merchants or consumers. The tire wall will also be printed with styles or models, and the new tire manufacturers will also put stickers on the tread of famous styles and sizes. So some tires are the only model, a brand can not find.

Three. Tire code resolution

Section width: the metric series is in mm, and the inch series is in inch, as shown in the section width of 120mm.

Flat ratio: the number on the flat ratio refers to the proportion and is expressed in the unit of percentage, as shown in the figure, the flat ratio is 70%, and the number greater than 80 is a multiple of 10, and the number less than 80 is a multiple of 5.

Structure code: the tire structure is marked with "-" cross-layer tires, "B" ring cross-layer tires, and "R" radial layer tires.

Wheel diameter code: represents the size of the tire, the number is the diameter of the wheel.

Structure code: the tire structure is marked with "-" cross-layer tires, "B" ring cross-layer tires, and "R" radial layer tires.

Wheel diameter code: represents the size of the tire, the number is the diameter of the wheel.

Use code: for metric tires with a diameter of 13 or more, M/C will be added to the diameter code to mark them as locomotive tires.

Load index: a number indicating the load capacity of a tire.

Maximum speed: the corresponding speed of the tire is denoted by the English code.If the maximum speed is above 240km/h, "V" or "Z" shall be marked before the structure code. Usually anything above 240 is denoted by ZR.

Iv. Production time

Tires also have a storage period, if the factory for a long time or a long time exposed to the tire, will become commonly known as "fossil tire", for driving on the safety concerns.So I'm going to show you how to identify the year a tire was made. The first two digits are weeks and the last two digits are years. As shown in the figure, they represent the tires produced in the 24th week of 2017. However, generally speaking, tires are kept for about 5 years.

5. Description of various marks

TUBELESS represents TUBELESS, while RADIAL at the rear is RADIAL.

Mark maximum load and maximum charge pressure for cold tires.

Tire wear indicator

In the tire groove, there are usually protruding signs, used to test whether the tire tread is sufficient. In the tire wall or the most edge of the tread, there will be a sign every small section. In the past, it was usually a triangle symbol.

With this tire wear situation, the tread and the tire groove in the indicator point have reached the same plane, also represents the tire life has been almost.

Presumably, readers after reading the introduction of the above six points, can have a preliminary understanding of the signs on the tire wall, the future in the choice of tires, can be based on their own car tire specifications, find the same specifications of tires. And how to check the wear indication to confirm the current situation of the tire, for the preparation for a long ride before the preparation is also very important.
