Tire maintenance for motor vehicles is based on several factors. The chief reason for tire replacement is friction from moving contact with road surfaces, causing the tread on the outer perimeter of tires to eventually wear away. When the tread depth becomes too shallow, like for example below 3.2 mm (4/32 in), the tire is worn out and should ...
Renshaw has all the original paperwork and traced the manufacturing stamp on the Buick’s tubeless tires to February 1966, making them 58 years old. Goodyear Tire & Rubber Co. advertises new ...
Retread (also known as recap or remold) is a re-manufacturing process for tires that replace the tread on worn tires. [1] [2] Retreading is applied to casings of spent tires that have been inspected and repaired. [3] It preserves about 90% of the material in spent tires and the material cost is about 20% compared to manufacturing a new one.
[citation needed] The Michelin PAX system latitude LX4 tires apparently did not have the claimed lifetime, and the lack of universal repair and replacement facilities (PAX tires cannot be serviced at any tire shop, but only those with special equipment and specially trained personnel) and the cost to replace PAX tires were major factors for the ...
A run-flat tire is a pneumatic vehicle tire designed to resist the effects of deflation when punctured, allowing the vehicle to continue to be driven at reduced speeds for limited distances. First developed by tire manufacturer Michelin in the 1930s, run-flat tires were introduced to the public market in the 1980s.
Tire stockpiles create a great health and safety risk. Tire fires can easily occur, burning for long periods, up to a month and also creating substantial pollution in the air and ground. Recycling helps to reduce the number of tires in storage. An additional health risk, tire piles provide harborage for vermin and a breeding ground for ...
However, now, bigger versions of the heavy-duty tire changers are designed to mount/demount tires up to 95 inches (2.4 m) in diameter and also feature a hydraulically operated self-centering four-jaw chuck with clamping jaws that can clamp from 14 to 58 inches (0.36 to 1.47 m) either from the wheel’s inside or from the center bore.

As the tire rotates and spring elements with different spring constants enter and exit the contact area, the lateral force will change. As the tire rotates it may exert a lateral force on the order of 100 N (22 lbf), causing steering pull in one direction. It would be typical for the force to vary up and down from this value.
