What are the figures above the car tires?
There are, tire production date, tire size and so on. ISO international quality certification representation, eg 250/60 R 15 89 H 250 - Tire width (mm) 60 - Flat ratio R - Radial structure 15 - Tire diameter (in) 89 - Maximum load H - Highest speed
Specifications, pressure values, production date. factory
Hello, the numbers and symbols on the tires reflect the size and data of the tire as a whole, 245: tire tires wide. 45: tire flat ratio. R: Radial tire. 96: Maximum load of tire. V: the highest speed of the tires.
Example; 190 / 60R18 90T indicates the specifications of the tire. 190: cross-sectional width (mm) 60: aspect ratio of 65% R: R = radial tire structure 18: rim diameter 18 inches 90: indicates the load index (this index corresponds to the load capacity of 600kg) T: that the highest The speed of not more than 190KM / H Tire specifications: car tire specifications commonly used a set of numbers that the previous number that tire cross-section width, the latter said the rim diameter in inches. For example, 210 / 50R18 represents a tire width of 210 mm, a flattening ratio of 50, and a rim diameter of 18 inches. The middle of the letter or symbol has a special meaning: "X" that high-pressure tire; "R", "Z" said radial tire; "a" that low-pressure tire.
