trunking index）
Car tire speed rating and
Officially, the speed rating indicates the maximum speed of a tyre under specified conditions.
The letter A to Z represents the rate of the tire from 4.8 km/h to 300 km/h.
The commonly used speed grades are:
P 150 km/h
Q 160 km/h
S 180 km/h
T 190 km/h
H 210 km/H
triangle轮胎V 240 km/h
W 270 km/h
Y 300 km/h
Z ZR speed is above 240km/h
ZR can be used to indicate a ZR in the specification of the tire. If P275/40ZR17 93W, then the maximum speed rating (" W "in" 93W ") is 270 km/h.
In the recent regulation for the standardization of tire identification, the use of all levels except the infinitely variable z-speed level is stated,
Both speed symbols and load coefficients are included.
For example: P225/60r1595h
The use of the tire indicates that the maximum load capacity of the tire is 690 kg and the maximum speed is 210km/h.
The "speed level" is a number that corresponds to the maximum speed supported by a tire. Note: this speed level is only related to the speed of the tire, not the proposed speed limit. Please control within the legal speed range.
The "load index" is a number that corresponds to the maximum load weight (unit: kg), indicating the maximum weight that the tire can bear in normal inflation. You can also find the maximum deadweight number in a molded, pound, or kilogram unit on the other side of the tire side.
"Tire width" refers to the width of the tire (the distance between the two sides, unit: mm). This tire has a width of 185 mm.
"Flat ratio" refers to the ratio of the width of the fetus to
the height of the fetus. "65" indicates that the tire height is equal to 65 percent of the tire width.
"R" represents the meridional structure, indicating that the fabric layer (i.e., the tire cord) that forms the matrix is radiated into the fetus.
Rim diameter: represents the diameter of the rim used for this tire (unit: inch).
Pattern name: the pattern name of the tire, e.g. DUCARO GA.
The tire indicator line: a ring line at the end of the section to remind workers that the circle should be concentric with the rim of the rim when the tire is mounted.
Maximum inflating pressure: the most atmospheric pressure that can be subjected to this tire, which is kpa (kpa) and pounder/square inch (psi).
No inner tube: this tire is not required to have a inner tube when used.
The structure of the tire body: the structure of the tire tread and the tire side.
Wire belt: a material used in the structure of the tread to stabilize the body and enhance the load.
Abrasion point: there are small bumps in the grooves that the triangle points to. If the tire is worn to this height it can't
be used again. The abrasion limit of normal passenger car tyres is 1.6 mm.
Ground level: the level of the ability to hold the tire is divided into four levels: AA, A, B, C and AA.
Temperature series: the level of heat dissipation capacity of this tire is divided into three levels: A, B, C and A.
