Tyres are an important part of the car, marked on the car tyres are more than 10 species, to correctly identify these markers matching tyres, use, maintenance is very important for the protection of road safety and extend tyre life is important.
tyres: tyre size is the geometric parameters and physical properties of the flag data. tyre specifications used a set of numbers, said before a number indicates the tyre section width, the latter number represents the rim diameter, are in inches. In the middle of letters or symbols have special meaning: "x" represents the high-pressure tyres; "R", "Z", said radial; "a" represents the low-pressure tyres.
Levels: level refers to the tyre rubber ply layers nominal, not entyrely consistent with the actual number of plies, is an important indicator of the strength of the tyre. Level with the Chinese flag, such as 12 level; English signs, such as 〃14P. R〃 or 14 layers pole.
Cord material: Some tyre separate label, such as "nylon" (NYLON), after the general standard level; some tyre manufacturers marked in the world after the specification, use the first letter of pinyin said that if 9.00-20N, 7.50 -20G etc., N denotes nylon, G represents the wire, M represents cotton, R is rayon.
Load and pressure: general labeling and corresponding maximum load pressure, load the "kg" as a unit, pneumatic tyre pressure that the unit is "kPa."
Rim Specifications: Indicates the tyre rim to match the specifications used. For practical use, such as the "standard rim 5.00F".
Balance Flag: marked with colored rubber shapes printed on the sidewall, the tyre where the lightest, when the assembly is on the valve, in order to ensure the balance of the whole tyre.
Scroll direction: tread on the tyre slip on driving drainage particularly critical, so the pattern of asymmetry SUV tyre assembly scrolling direction arrow sign used to ensure that the design of adhesion, anti-slip properties. If installed wrong, then the opposite.
Wear limit signs: one side with rubber tyres, tyre wear limit marked block, once the tyre wear to achieve this flag should be replaced, otherwise they will be strong enough halfway puncture.
Production batch: a set of numbers and letters with signs indicating the year of manufacture and the number of tyres. Such as "98N08B5820" said the August 1998 Group B produced the first 5820 tyres. Condition batch number is used to identify the tyre and storage time.
Trademark: A trademark is a sign of tyre manufacturers, including trademarks text and images, is generally more prominent and eye-catching, easy to identify. Mostly connected with the manufacturer name and label.
Other marks: If the product grade, production license number and other ancillary signs. Can be used as the selection of reference material and information.
tyre marks are generally relatively standardized signs to identify clearly can rest assured purchase and after use.
The following is a common tyre size representation:
Example: 185 / 70R1486H
185: Tread Width (mm)
70: aspect ratio (height ÷ tyre tyre width)
R: radial structure
14: Wheel diameter (inches)
86: load index (expressed as a load corresponding to the maximum 530 kg)
H: Speed Code (representing the highest safe speed is 210 km / h)
