What is the thickness of a car tire?

Generally, the tread thickness of a car tire is about 13 millimeters, with a tread pattern depth of 7 millimeters and a tread thickness of 6 millimeters. The sidewall thickness is 5 millimeters. For off-road vehicle tires, the sidewall thickness is about 20 millimeters, with a sidewall pattern depth of 14 millimeters and a sidewall thickness of 6 millimeters. The sidewall thickness is 10 millimeters. Car tires can be divided into pneumatic tires and solid tires based on their carcass structure, with most modern cars using pneumatic tires. Depending on the internal air pressure, pneumatic tires can be categorized into high-pressure tires, low-pressure tires, and ultra-low-pressure tires. Low-pressure tires are commonly used in various types of vehicles. Pneumatic tires can also be divided into tube tires and tubeless tires based on their construction. Tubeless tires are widely used in passenger cars. Depending on the arrangement of the internal cord layers and cushion layers, tires can be further classified into radial tires and bias-ply tires. Radial tires are commonly used in cars, and their specifications are usually marked on the sidewall. Car tires are one of the essential components of a vehicle. Currently, most passenger car tires sold in the market are tubeless tires. Tubeless tires have an inner liner made of synthetic rubber, which seals the compressed air inside the tire. They ensure good adhesion between the wheel and the road, improve the vehicle's traction, braking, and off-road performance, and bear the weight of the car. The important role of tires in automobiles is increasingly being recognized.

Is it illegal to put stickers on a car?

This depends on the area covered by the stickers. If the stickers cover no more than 30% of the car's surface, or if the car is registered with the vehicle management office after applying the stickers, it is not considered illegal. Stickers that do not meet the above requirements are illegal. Sticker colors: Ordinary cars are prohibited from using colors reserved for special vehicles. According to Chinese law, although vehicle owners can modify the color of their cars, colors such as fire engine red, engineering rescue yellow, and the white-over-blue combination used for national administrative law enforcement are reserved for special vehicles and cannot be used on ordinary cars. Precautions: Car stickers must not affect safe driving, and their content must be healthy and positive. The law states that if the spraying, labeling, or advertising on a vehicle affects safe driving, a fine will be imposed. If the area covered by the stickers is too large (exceeding 30%) and has not been approved by the vehicle management office, causing the car to differ from the photo on the driving license, it is considered an illegal modification and will also result in a fine.

What is the vehicle tax rate?

Article 4 of the "Vehicle Purchase Tax Law of the People's Republic of China": The vehicle purchase tax rate is 10%. The vehicle purchase tax is calculated based on the ad valorem rate method. The calculation formula is: Tax payable = Taxable price × Tax rate. If a consumer purchases a domestically produced private vehicle, the taxable price is the total payment made to the dealer, including additional fees, but excluding the value-added tax (VAT) (17% rate). Since the purchase price on the special invoice for vehicle sales includes VAT, the 17% VAT must first be deducted when calculating the vehicle purchase tax. That is, the taxable price for vehicle purchase tax = Invoice price ÷ 1.17, and then the 10% tax rate is applied. The vehicle purchase tax is levied as a one-time payment. If a vehicle has already been subject to the vehicle purchase tax, it will not be levied again. The tax payable for vehicle purchase is calculated by multiplying the taxable price of the vehicle by the tax rate. If the taxable price declared by the taxpayer is significantly low without a valid reason, the tax authority will determine the tax payable in accordance with the "Tax Collection and Administration Law of the People's Republic of China." If the payment for the taxable vehicle is settled in foreign currency, it will be converted into RMB based on the central exchange rate of the RMB on the day of tax declaration. The vehicle purchase tax has a time limit. It must be paid within 60 days from the date of the vehicle purchase invoice. Late payments will incur a daily late fee of 0.05% of the tax amount. After the vehicle purchase tax is paid, the tax authority will issue a "Vehicle Purchase Tax Payment Certificate," which the owner must keep safe and does not need to carry in the vehicle. If the certificate is lost, it must be reissued.
