Tire installation indicator line: a circular line located at the sub-opening, and a single or multi-ring rubber rib formed at the joint between the bead and the sidewall, which is mainly used to indicate the correct assembly of the tire on the rim; This circle should be concentric with the circle formed by the rim edge when installing the tire. ?
Maximum inflation pressure: represents the maximum atmospheric pressure that the tire can withstand, in kilopascals (kpa) and pounds per square inch (psi)?
Tubeless: it means that this kind of tire does not need an inner tube when it is used. ?
Carcass structure: explain the composition of tread and sidewall of this tire. ? Pedal: 2? Polyester? +? 2? Steel? +? 2? Nylon; Side wall plate:? 2? Polyester "?
Steel wire belt: a material in the tread structure, which is used to stabilize the carcass and enhance the load. ?
Wear indicator: there will be small protrusions in the tread groove pointed by this triangle. If the tire is worn to this height, it can no longer be used. The wear limit of general passenger car tires is 1.6 mm?
Grip grade: the grade representing the grip ability of the tire. * * * is divided into four grades: AA, A, B, C, AA is the highest. ?
Temperature grade: the grade representing the heat dissipation capacity of the tire. * * * is divided into three grades: A, B and C, with A being the highest.
Tread wear is a wear index of 20. ; ? The larger the value, the more wear-resistant.
The grip is divided into four grades AA>A & gtB& gt；; C
Temperature is a high-speed classification, with three grades A & gtB& gt；; C
These things are basically on the tire sidewall, but the tires of each manufacturer are still different. You can ask again for details.
