and nails. Some casings are repaired and some are discarded. Tires can be retreaded multiple times if the casing is in usable condition. Tires used for short delivery vehicles are retreaded more than long haul tires over the life of the tire body. Casings fit for retreading have the old tread buffed
59:
Some applications for retreaded tires are airplanes, racing cars, buses and delivery trucks. Use of retreaded tires was common historically, but as of 2008, it was seldom used for passenger vehicles, mainly due to discomfort on the road, safety issues and cheaper tire brands surfacing on the market.
130:
Following a thorough quality inspection, the worn tire tread is removed from the casing by buffing. Raw rubber is then applied to the tire casing and it is then placed in a mold where tread is formed. A dedicated mold is required for each tire size and tread design. This tread application method is

Retread tires in service lower the volume of raw materials required for the manufacturing of a new tire. This includes a pronounced reduction in the use of oil. In fact, the US EPA estimated a greater than 75% savings in oil used for a retread as compared to a new tire. This also means significant

Material cost for a retreaded tire is about 20% that of making a new tire. About 90% of the original tires by weight is retained in retreaded tires. A 1997 study estimates that then current generation of commercial vehicles tires to last up to 600,000 miles if they're retreaded two to three times.
208:
In addition to reducing the amount of raw materials extracted, retread tires also minimize the amount of waste that ends up in landfills. The latest figures by the US EPA indicate that over 11.2 M waste tires were dumped into the U.S. municipal solid waste stream. To understand this figure, it is

frequently found on highways. The NHTSA is continuing research to determine the proportion of tire debris from retreads in comparison to new tires. Additionally, the NHTSA is researching the cause of tire failure and the crash safety problem posed by tire failures.
155:
In Europe all retreads, by law, must be manufactured according to EC Regulation 108 (car tires) or 109 (commercial vehicle tires). As part of this regulation all tires must be tested according to the same load and speed criteria as those undergone by new tires.

on worn tires. Retreading is applied to casings of spent tires that have been inspected and repaired. It preserves about 90% of the material in spent tires and the material cost is about 20% compared to manufacturing a new one.

There are two main processes used for retreading tires, called Mold Cure and Pre Cure. Both processes start with the inspection of the tire, followed by non-destructive inspection method such as
