Again, find the formula for calculating the cost of tires

No need to add it. Only the cost of kilometers is calculated.

There are usually a lot of numbers and letters on the tires, and these numbers and letters represent different meanings. Most of the wheel fluid tires have DOT logo, tire DOT is the meaning of the United States Department of Transportation certification, usually followed by a string of numeric letters, which represent the origin information of the tire and the factory**, the last four digits are the production date of the tire. The first two represent the number of weeks of production, and the last two represent the year of production.

In addition, we can also see that there are many numbers and letters on the tires, some are tire brands, M+S means that mud and snow are applicable, some tires will be marked as M S, M&S or MS, and some are marked All, that is, the same tires in all seasons. There are also a series of numbers and letters similar to 195 60 R15 88T, which identify the specifications of the tire

195: refers to the tread width of the tire, which means that the tread width of this tire is 195mm.

60: refers to the flat ratio of the tire, not that the tire thickness is 60mm, but that the flat ratio of the tire is 60% (flat ratio = tire height and tire width 100%).

r: refers to the type of tire, which means that the first balance hole of this tire is a radial tire.

15: Refers to the wheel size, this tire is suitable for 15-inch wheels.

88: refers to the load index of the tire, that is, the maximum load of the tire, the maximum load of this tire is 560kg.

t: refers to the speed class of the tire, that is, the maximum speed of the tire, the maximum speed of this tire is 190km h.

In addition to this, there are also numbers on the sidewall of the tire to represent the performance of the tire

The wear resistance index Treadwear reflects the wear resistance of the tire, the higher the value means that the tire is more wear-resistant, and it also means that the hardness of the tire is greater, the worse the comfort, and vice versa. Generally, the wear resistance index is moderate at 280-320. The wear resistance index of the tire is 320, indicating that the comfort of this dry tire is better.

traction represents the traction index, and the following letters represent the strength of the grip, from high to low, AA, A, B, C. AA indicates that the tire has very strong traction.

temperature represents the heat generation index of the tire, and the following letters indicate the heat generation level of the tire, and the heat generation level of car tires from high to low are A, B, and C. The heat generation level of this tire is A, which means that the high temperature resistance is excellent.

I wish you a pleasant ride, thank you.
