Pattern code: represents the tire pattern name, for example: DUCARO?GA. ?

Tire installation indicator line: a circle of line located at the sub-port, a single-ring or multi-ring rubber rib molded at the junction of the bead and sidewall, mainly used to indicate that the tire is correctly assembled on the rim. marking line; when installing the tire, this circle should be concentric with the circle formed by the edge of the rim. ?

Maximum inflation pressure: represents the maximum air pressure that this tire can withstand, in kilopascals (kpa) and pounds per square inch (psi)?

Tubeless tubes: Description This tire does not require an inner tube when in use. ?

Carcass structure: describes the composition of the tread and sidewall of this tire. ?TREAD?PLIES: 2?POLYESTER?+?2?STEEL?+?2?NYLON; SIDEWALL?PLIES: ?2?POLYESTER”?

Steel wire belt: one of the tread structures Material used to stabilize the carcass and enhance load-bearing capacity. ?

Wear indicator point: There will be a small protrusion in the tread groove pointed by this triangle. If the tire wears to this height, it will not. It can be used again. The wear limit of general passenger car tires is 1.6 mm?

Grip grade: represents the grade of the tire's grip ability, which is divided into 4 levels: AA, A, B, C, AA level is the highest?

Temperature level: represents the level of heat dissipation ability of this tire. It is divided into 3 levels: A, B, C, A. The highest level.

TREADWEAR is the wear resistance index in units of 20?;?The larger the value, the more wear-resistant it is.

TRACTION is the grip level divided into four levels AA>A>B>C< /p>

TEMPERATURE has three levels of high-speed performance: A>B>C

These are basically the things on the tire sidewalls, but there are still certain differences in the tires of each manufacturer. You can ask again
