For example, automobile tires will display a set of numbers in large letters, which usually start with "1" or "2". Looking directly at the picture, 2 15/55R 17 96W, only this 2 15/55R 17 is the representation of a single tyre size. Where 96W is the speed and load index of tire performance. Another example is Mercedes-Benz GLK, whose tire size is 255/45R 19.
How to see the parameters on the tire?
Take a chestnut: 205/55r1691v.
205 is the tire cross-sectional width, and the unit of millimeter is the tire width.
55 is the flatness ratio, and the thickness ratio is 205*55%, which is the thickness of your tire.
R is a radial tire, which is generally the case now.
16 the unit of rim diameter and inner diameter is 25.4 mm
9 1 is the load index. There is a load index table, and each number represents the maximum weight of the tire.
V is the speed level of 240 km/h.
I hope it helps you.
What do you think of the tire model?
Hello!
Tire size marks are engraved on the sidewall of each tire. For example, tyre size is 205/55 R 16 94H. 205: section width (mm)55: aspect ratio 55% r: r = radial tire structure 16: rim diameter 16 inch 94: indicates load index (the load capacity corresponding to this index is 670kg)H: indicates that the maximum speed shall not exceed 2 10KM/H More tire identification.

Tire information can be found on the sidewall of the tire. You can compare this picture.

What do you think of the tire model?
Hello! There is a set of numbers on the tire sidewall, as shown in the figure below. 235/45 R 17 is the specification and model of this tire. 97 is the load index of the tire, and W is the speed grade of the tire!

What do you think of the tire size and style?
The tire code in the international standard of tire code indicates the percentage of section height and flatness ratio in millimeters, which are: tire model code, rim diameter, load index (allowable bearing mass code) and allowable speed code in turn. For example, in 175/70R 14 77H, 175 means that the tire width is 175mm, and 70 means that the section height is 70% of the width, the rim diameter is 14 inch, the load index is 77, and the allowable speed is class H.
What do you think of the tire size?
For example: Tong Jia tire P205/55R 16 89H.
"P" refers to automobile tires. (Used to distinguish tires suitable for trucks or other models)
"205" refers to the width of the tire section, that is, the width between two sidewalls (in millimeters). This width varies with the rim width matching the tire: wide rim matches wide tire and narrow rim matches narrow tire. The tire width marked on the sidewall refers to the width when the tire is mounted on the rim with the recommended width.
"55" is the flat rate of tire, which is the ratio of tire width to tire height. Here, the tire height accounts for 65% of the tire width. The smaller the value, the flatter it is.
"R" refers to the structure of the tire, which means that the tire has a radial structure, that is, its plies are arranged in the carcass in an auxiliary way. "B" indicates that the tire has a diagonal structure, and the automobile tire with diagonal structure no longer exists.
"16" indicates the rim diameter (inches). This tire must match the rim of 15 inch, otherwise it cannot be installed.
"89" stands for load index: the maximum load of this tire is 1 279 lbs. Different load indexes represent different maximum loads (usually in pounds or kilograms).
"H" stands for speed grade: the top speed of this tire is 130 miles per hour. The old European tire bead marking system is represented by 2 15/65HR 15. Different English letters indicate different speed levels.
"DOT" means that the tire meets the safety standards stipulated by the US Department of Transportation (DOT). The numbers and letters of 1 1 immediately after "DOT" indicate the identification number or serial number of the tire.
How do tire sizes view cars?
205 denotes the nominal cross-sectional width (inches) of the tire.
65 denotes the flattening rate of the tire (flattening rate = tire height H/ tire width b).
(Tire height h: the linear distance from the bead to the center of the tread)
(Tire width b: the longest straight line distance between two sidewalls)
The lower the air leakage rate of the tire, the smoother the tire and the better the handling, but the tire feels less elastic and vibrates more when riding. ..
R indicates that the tire has a radial structure.
16 indicates the standard diameter of the rim (inches).
What do you think of the size of electric car tires?
Then you can buy 130/60- 10, but this tire is too wide, and it is dangerous to install it on the 10 inch wheel hub of an electric car. At most, 1 10 is enough, and the visual effect of tires with a width of 1 1 cm is very rough. 130 is the width in millimeters, and 60 is the aspect ratio in%. The smaller the number, the flatter and rounder the tread. 10 means 10 inch hub.
What do you think of the size of car tires? Size?
Usually, the identification of automobile tire size is ***/** R** * and all parts are numbers. (For example: 205/55R 16)
The tire size you buy must be the same as that of the original car when it was assembled. If you need to change the tire size, you must go to a professional refit shop to upgrade the tire, or consult a car manufacturer.
Take 205/55R 16 as an example:
205= Cross-sectional width is 205 mm..
55= Aspect ratio is 55%
R= radial tire structure
16= the rim diameter is 16 inch.
Different patterns are available for different specifications.
