tireAnd wheels are two different things... Tires are classified according to vehicle types, and can be roughly divided into 8 types. Namely: PC-car tires; LT-light truck tires; TB-truck and bus tires; AG-agricultural vehicle tires; OTR-engineering vehicle tires; ID-industrial vehicle tires; AC-aircraft tires; MC-motorcycle tires. The commonly used classification methods are divided into: ordinary bias tires, substitution bias tires and radial tires. At present, almost all radial tires are used. The main advantages of radial tires are: low adhesion, low tread slip, low rolling resistance, good heat dissipation performance, large load capacity, long service life, etc.

Tires are like other commodities, they also have information such as production date and speed and load rating reflected on the tires.

The aspect ratio refers to the ratio of the height from the rim to the tread surface to the maximum width measured on the cross-section of the tire, expressed as a percentage, that is, the percentage of the height to the width. Take the 205/60R15 specification tire as an example, the maximum width of its cross section is 205 mm, the tire inner diameter is 15 inches, and the aspect ratio is 60.

In theory, for the same car, if the overall tire size must be kept the same, the wider the tread, the smaller the aspect ratio. At this time, the lateral force that can be tolerated is greater, so the grip is stronger, but the longitudinal force that can be tolerated is smaller, and the comfort is worse. vice versa.

Generally speaking, the tires that the vehicle is equipped with at the factory are the best specifications selected by the manufacturer after repeated tests. If a car owner wants to change the tire size, it must be carried out under the guidance of professionals, not at will, because this involves many problems, a little negligence may cause harm to driving safety. In addition, low-profile tires will appear more "delicate", so you should pay more attention and care during use.

Have you noticed that you can find them on standard cars for car tire maintenance. Some are on the label next to the door of the passenger compartment, some are in the storage box, and some are on the lid of the mailbox, with a mark on it.

If you haven’t observed it carefully before, remember to check it out when you use the car in the future. When you go to the tire store, you can refer to the above instructions. Try to choose a professional tire store to do tire maintenance.

Tire common sense is basically this, tires involve driving safety, and daily maintenance must not be ignored. It is important to prepare some tire changing tools in the car (if you can change it, it is recommended to replace the spare tire by yourself).If you really don’t, it is recommended to keep a 24-hour rescuecar repairThe store’s phone, just in case you need it...
