What does the tyre cross section refer to?Can you give me a specific definition? It's better to have pictures. Thank you
According to the national standard, to mark the production number in the tire on both sides of the factory brand, size, level, the maximum load and the corresponding pressure, carcass pinyin code, installation requirements and direction mark etc.. The letter "185/65 R14" mentioned in your letter is only part of the tire number in the tire code. The carcass cord material is expressed in Chinese phonetic alphabet
Such as M- cotton cord fabric, R- rayon cord fabric, N- nylon cord, G- steel cord fabric, ZG- steel radial ply tire. A flat tire section width and describes two important indicators of the tire size. The section width of the tyre refers to the maximum distance between the two outer sides after the tyre is inflated according to the rules. The aspect ratio (H/B) of the tire is the ratio of the section height of the tire to the width of the section B, such as the passenger car radial tire, which is divided into 60, 65, 70, 75, 80 and other H series.
The general radial passenger car tire specifications label includes the following content: A tire section width, mm B tire high aspect ratio C tire structure mark D rim diameter, unit load index F inch E speed symbol tire nominal aspect ratio refers to the height of section is installed in the theory on the rim of the tire and section width ratio. For example, a vehicle tire model 195/60 R14 85 H, "195" tire section width is 195 mm; "60" tire high aspect ratio is 0.6; "R" said tire radial tire; "14" rim diameter is 14 inches; "85" means the maximum load of tire 515 kg; "H" shows that the tire speed level.
