1, 1.6 displacement vehicle's size specification is: 215/55r16;
2.2.0 The size specification of the displacement vehicle is 2 15/50R 17.
Most tire models are marked in the form of 2 15/50R 17. The meanings of these numbers are: 2 15 represents the tire section width in mm, and the width of a general tire is between 145-285 mm with an interval of10 mm; ; 50 is the flattening ratio, that is, the ratio of tire sidewall height to tire section width.
50 stands for 50%, and the flattening rate of ordinary tires is between 30% and 80%. Generally speaking, flat rate should not be adopted for ordinary cars >: It is recommended that 75% of tires, luxury cars and high-performance sports cars adopt flat rate.
Extended data:
Tire size is usually represented by a set of numbers, with the former number representing the tire section width and the latter number representing the rim diameter in inches. For example, 165/70R 14 represents a radial tire with a tire width of 165mm, a flat rate of 70, and a rim diameter of 14 inch.
Some tires also contain other letters or symbols with special meanings: "X" stands for high pressure tire; "c" stands for enhanced type; "b" means oblique; "One" refers to the low-pressure tire. M and S are abbreviations for mud and snow respectively, which means that this kind of tire is suitable for use on icy and muddy roads.
The sidewall of some tires is marked with the words "arrow" or "outside" to indicate the direction of tire rotation. If there is a small umbrella sign on the tire wall, it means that this kind of tire is suitable for driving on rainy days or wet roads. The dot sign indicates that this kind of tire has been certified by the transportation departments of the United States and Canada.
The dot is usually followed by a 4-digit number, which, unlike other characters, is not produced in the early mold, but pressed on the tire in the later stage, such as (1805), indicating the production date of the tire. 05 is 2005, 18 is 18 weeks.
There is also a very special sign on the tire: wear replacement instructions. Different manufacturers have different signs. Michelin is a man with small tires, Pirelli shows the TWI logo, and some tires are represented by conspicuous white.
