How do you distinguish a steel tire from an ordinary one in a truck tire?

Answer:

Cord carcass arrangement is different from the bias tire, radial tire cord is not mutually staggered, but with the tire section close to parallel, like the earth's meridian arrangement, cord angle is small, usually 0 degrees, not to maintain the intersection between the carcass cords, when the tire in the running process, the stress around the crown increase, will cause the circumferential stretch, carcass radial gap.Close to the circumferential direction dealing with cord layer so the buffer layer of radial tire, 90 degrees intersect with the cord angle, generally 70 to 78 degrees, forming a rigid ring with hardly done, the whole tire fixed, tire circumferential deformation, the stress buffer 60% to 70% layer under the entire tire, become the main force components of radial tire, called radial tire belt. The ply design of radial ply tire is very important. It must be of good rigidity. It can be made of multi layer, big angle, high strength and difficult to stretch fiber material, such as steel wire or glass fiber.
That is, tubeless pneumatic tires, also known as "low pressure tire" "inflatable tire."". Vacuum tires have been used more and more widely in motorcycles, cars, buses and trucks in recent years. Vacuum tires have high elasticity and wear resistance, and have good adhesion and heat dissipation performance.
Also known as ordinary structural tires, is an old-fashioned structure of the tire. The tire is composed of tread, ply (carcass), buffer layer and bead, ply tyre is the skeleton, to keep the shape and size of the tire, usually made of multi-layer into even hanging tape (cord) with a rubber cord cord attached to, and tread the center line of approximately 35 angle, from one side of the bead through the tread to the other side of the bead. An air filled tire arranged between the carcass ply and the buffer layer adjacent to the ply cord and arranged at an angle of less than 90 DEG C with the center of the tread. In the selection of nylon, polyester fiber or a high strength cord material, can greatly improve the tire load carrying capacity, improve the tire performance, is a commonly used modern automobile tires. This kind of tyre has a good longitudinal rigidity and is suitable for traveling at ordinary speed.
Truck tyres and ordinary tyres can be identified by following the relevant knowledge:We usually hear oblique tyres (ordinary), wire tyres, meridian tyres, Lun Lun tires and vacuum tyres. How do these tyres differentiate between good and bad?:
