Tire size, trademark and factory name, standard wheel hub, production number and maximum load code are printed on the side of the car, and ""marks are printed on the shoulder along the circumference and equally. On the crown surface of the tire, a boss with a height of 1.6 mm is axially arranged at the bottom of the groove equally divided along the tire circumference (this is the case in most countries). When the tire tread is worn to the bottom of the groove 1.6 mm, this part of the groove first breaks and obvious cracks appear, reminding the driver that the tire must be replaced. When the tire track is worn below 1.6 mm in the groove, it will often slip and increase fuel consumption, which will not only affect the handling of the vehicle, but also easily lead to traffic accidents.
