HOW A TIRE IS REMANUFACTURED:
Remanufacturing tires is a valuable resource in saving our environment. While the tread of the tire may be worn away from highway use, many tire casings are valuable for their recycling potential. TreadWright, Inc. has 30 years of experience in providing high quality retread tires, saving the user money and saving our environment.
Remanufacturing a tire is accomplished in several steps.
-
Casings are acquired from tire dealers who are familiar with the process and understand the proper storage of a used casing until they can be picked up. When the tire is received at our remanufacturing plant, it is again stored in a vertical position on racks where no tire is placed on top of it which could crush the sidewall and cause serious internal damage. This quality control feature costs us more to do, but it is important to the quality of the tire.
-
Inspection of each casing is done in several stages. First, the tire dealer is setting aside casings that could possibly be used for recycling. The next visual inspection is done as the tires are accepted for transport to our remanufacturing plant. And finally, the casing is brought into our plant inspection department where it is carefully inspected under excellent lighting, with non-destructive sophisticated inspection equipment that is available to the industry. Casings also receive a complete rigorous visual inspection at this point. Accepted casings are now placed into the remanufacturing process.
-
The process in the casings begins with a high speed buffing
which mechanically removes the remaining old tread. Today's buffers are extremely accurate and will remove the proper amount of old rubber while truing the tire to an exact specified, laser ensured, diameter and radius.
-
Application of new rubber to the tread area is the next step. The unvulcanized tread rubber is applied to the tire with a preset adhesive that begins the bonding of the new tread rubber to the casing. The tire is set aside for the adhesive to set.
-
Computer balance. We rebalance the tire to insure smooth running & good performance. Warranted to be less than 7 oz.
-
Molding of the new tire tread is the next step. The tire casing with the new unvulcanized tread rubber is placed in a rigid mold which contains the tread design in the tread area. The mold is heated and the rubber in the tread area vulcanizes and adheres to the casing with the new tread design molded in. This vulcanization process also bonds the tread rubber to the casing through the use of heat, pressure and time.
-
Compression-Cured in automatic press & segmented matrices.
Compression-cure is a superior method of remanufacturing Radial tires. It provides constant high pressure during cure resulting in a high density bond like new curing. The result: A high quality like new tire!
-
Trimming of the completed tire removes any excess rubber. The tire is then placed into racked storage to await a final inspection.
-
A final inspection of the tire is then performed that insures that only tires that meet industry quality standards are allowed to leave the remanufacturing plant. The tire is now ready to return to full service and a second (or third) life as a safe and economical alternative to high priced new tires.
-
Remanufactured tires are your best tire value. Truckers, fleet operators and consumers can expect substantial savings by using remanufactured tires. For additional information on remanufactured tires and to purchase tires, contact TreadWright, Inc.

REMANUFACTURED TIRE FACTS
|
|
Remanufacturing of tires has evolved into a high-tech process that provides quality tires at affordable prices. Remanufactured tires are a great way to keep your tire replacement costs down, and for businesses it is a way to keep the profits up.
Here are some remanufactured tire facts for your consideration.
-
For most fleets, tires represent the third largest item in their operating budget, right after labor and fuel costs.
-
Fleet managers have found they can reduce their tire costs by at least 50 percent by remanufacturing their tire casings at least twice.
- The lowest possible cost-per-mile is achieved with a good tire management program that includes the use of quality remanufactured tires.
- Remanufactured tires are the replacement tire of choice for most truckers.
- Remanufactured tires are not only cost effective, but they are also dependable, reliable and safe. They are used by truckers with scheduled delivery times, small package delivery companies with guaranteed delivery times, on commercial and military jets and by most school bus operators.
- Remanufactured tires are also environmentally friendly. Tires are basically petrochemical products. It takes 22 gallons of oil to manufacture one new truck tire. Most of the oil is found in the casing, which is reused in the remanufacturing process. As a result, it takes only 7 gallons of oil to produce a quality remanufactured tire. It also keeps the casing from going to a landfill.

TIRE MAINTENANCE TIPS
Temperature Effects:
Air pressure is affected by temperature. The air under pressure in a tire is no exception. Typically, an inflation pressure can change by 1 PSI for every 10 degrees Fahrenheit of temperature change. Higher temperature means increased pressure. For example, if a tire is inflated to 35 PSI on an 80-degree July day, it could lose enough air to have an inflation pressure of 23 PSI on a 20-degree day the following January. This represents a loss of 6 PSI over six months and an additional loss of 6 PSI due to the 60 degree temperature change. At 23 PSI, this tire is severely under inflated. For safety and vehicle performance you should check tire inflation at least once each month when the tires are cold (ambient air temperature or if the vehicle has not been driven for several hours.
Pressure Loss:
While a tire is carefully designed to contain air, some leaks out. Air leakage can occur over time through the tire itself, through the valve core and at the rim. Typically, leakage results in a loss of about 1 PSI per month. At that rate it won't take long for a tire to become excessively under inflated. Undetected punctures, bruise damage, cuts and rim valve damage may produce more rapid air loss. Under inflated tires in general and performance radials in particular, may not convey a message of under inflation to the driver until heat failure or rim dislodgment occurs. Therefore, cold inflation pressures must be checked as often as possible.
Inflation:
Under inflation can cause many tire related problems. Since a tires load capacity is largely determined by its inflation pressure, under inflation results in an overloaded tire. An under inflated tire operates at high deflection resulting in decreased fuel economy, sluggish handling and excessive shoulder wear. High deflection also causes heat buildup leading to catastrophic tire failure. The correct profile for full contact with the road which results in optimum tire performance. Because radial ply tires have a characteristic bulge in the sidewall even when properly inflated, it is impossible to visually determine the degree of inflation. Use a reliable air gauge to check inflation pressure.
Tire Rotation:
Tire rotation is important for even tread wear and a long tread life. As a tire is driven on a road surface, it begins to wear. Tire wear rarely takes place uniformly on tires, because each tire is mounted at a different position on a vehicle. Tires should be rotated at frequent and regular intervals. Tires can be rotated conveniently during a regular oil change, which for most vehicles occurs every 5,000 to 7,500 miles.
Balancing:
Tire wheel balance is important for vehicle ride and stability and for customer satisfaction as well. Tires are manufactured to close tolerances for roundness and shape, but as a tire wears, the tire's mass may become unevenly distribute, and the original rim/tire balance may be affected. There are two approaches to wheel balancing: on-car balancing and off-car balancing. Various types of balancing equipment are available, including static and dynamic balancers for off-car work and mechanical and electronic balancers for on-car work.

<!--[endif]--> Tire Repair:
Nails and other objects may protrude into a tire causing internal damage that is not visible or apparent from the outside. A tire repair can be properly made only if the tire is removed from the rim, a through internal inspection is carried out, and repair is made from the inside out.
