Retreading is the process in which new tread rubber is bonded to a refurbished tire body, or a casing. The retread process is not new — it was invented in the early 1900s. But the process has evolved with technology, and is a reliable source for quality tires at a lower price point. 

Today, it is widely used by fleets of all sizes, but especially those with 1,000 or more units.

“There is a reason up to 90% of large fleets practice retreading – it’s smart, sustainable business,” said LaTres Jarrett, director of marketing, Bandag, Bridgestone Americas Tire Operations.

But how do you choose the right retread? Experts share their tips on the top factors to consider.

Define the Fleet Application

The process of choosing a retread is almost identical to choosing a new tire, according to Helmut Keller, Continental’s head of product management for Commercial Vehicle Tires in the Americas region.

“The customer needs to identify which wheel position the retread will be placed in and what application the retread will be used in,” he said. “For example, if the fleet is in an off-road construction application and needs a drive tire, it might select a drive retread with and chip- and chunk-resistant compound.”

Mahesh Kavaturu, marketing manager for Goodyear, agreed that the first step to choosing the right tire is determining your fleet’s needs. This can depend on your fleet’s vocation, designed return on new tire investment, how vehicles are used, and the driving conditions those vehicles may face.

“Different trucks and applications require different treads. Equipping a truck with the wrong tread design can lead to sub-optimal performance. The importance of consulting with a qualified retread expert cannot be understated,” Kavaturu said.

New technology allows fleets to find a product that’s tailored to their needs. One example is the ability to cut sipes, or the slits that make up a tread pattern, after the manufacturing process, which is called microsiping.

“For example, a winter retread pattern might have micro-sipe technology to ensure traction or a long-haul pattern might have a fuel-efficient tread compound technology to ensure low rolling resistance,” Keller said.

Know How It’s Done 

Jarett with Bridgestone noted that awareness of the process is important to understanding what a retread is and how effective it is.

“By understanding a manufacturer’s retread process from start to finish, fleets can feel confident in the final product,” she said.

Bandag, the business of Bridgestone dedicated to the research, development, and manufacturing of premium retread tires, goes through a robust manufacturing process.

“Bandag dealers utilize shearography, a highly advanced system utilizing more than 240 videos to uncover separations in the belt package, liner and bead areas, to ensure product quality and safety. Once a casing is approved for retreading, it goes through a 10-step process, including a final inspection before it’s returned to service,” Jarrett said. 

Continental also uses shearography during its retread process, which it calls ContiLifeCycle.

“During the detailed ContiLifeCycle manufacturing process, the casing is thoroughly inspected to ensure that the retreaded tire will last through its next life,” Keller said. “Every Continental retread goes through a shearography inspection as well as pressure testing on the final product. This helps ensure fleets receive a safe and reliable product.”

Kavaturu with Goodyear noted that low rolling resistance is an important factor for many fleets, and a feature of Goodyear’s UniCircle Technology.

“In addition to offering low-rolling resistance, Goodyear UniCircle treads, which are spliceless and positioned onto casings using laser-guided technology, offer enhanced traction and resistance to tearing and chunking. By leveraging compounding technology and tread designs, Goodyear continues to make strides in developing retreads that deliver like-new performance.”

For added assurance during retreading, Goodyear offers GTRACS, an automated system that allows fleets to follow casings through the retreading process. 

“GTRACS, which is available through the Goodyear Authorized Retreader network, uses bar codes to track the progress of a casing through the retread process. After a tire has been retreaded, GTRACS provides fleets with valuable data about their retreads in the form of easy-to-understand charts and graphs,” Kavaturu explained.

Retreads Aren’t Going Anywhere

By design, retreads are an environmentally friendly tire option for fleets. But sustainability goals aren’t the only reason retreads are growing in popularity. Eric Higgs, president of truck, bus, and retread tires for Bridgestone, notes that retread tires may become more appealing as autonomous vehicles hit the road.

“Looking ahead, we know the future is autonomous and we believe the retread value proposition only grows for a fleet of autonomous trucks,” Higgs said. “Without variations in driver behavior, tires likely will wear more evenly. Casings could conceivably last the entire life of an autonomous truck when coupled with retreading.”

Look Past the Misconceptions

Despite these sophisticated processes, some fleet operators may still hold on to myths and misconceptions about retreads. 

David Stevens, managing director for the Tire Retread & Repair Information Bureau (TRIB), said this is especially true among smaller fleets.

"If you have one or two trucks it’s harder to do testing and have a real, robust tire management program like these big fleets do. The reason that 90% of those large fleets with 1,000 of more trucks are using retreads at such a high percentage is that they know it makes economic sense for them,” Stevens said. 

Learning about the retread process is helpful, but seeing it in action can add another level of understanding. That’s why TRIB offers a video tour of a retread plant on its website.

“One of the best ways to convert people to understanding the benefits of retreading is when they go through a retread plant tour and they see how technologically sophisticated the process is,” Stevens explained.

Work With the Dealer

When choosing the right tire, it helps to consult the experts. Jarrett with Bridgestone recommends that fleets work with a dealer partner to develop a custom tire and retread program tailored to their specific business goals and objectives. 
She also noted that fleets should ensure their dealer has certifications and processes to ensure a good product.

“Fleets should look for partners who utilize ISO 9001:2008-certified tread rubber and have multiple inspection points to verify that a casing is suitable for retreading,” Jarrett explained.

Keller with Continental agreed that the dealer can offer valuable guidance. But fleets should make sure they are asked the right questions. Some of these questions include:

  • Are you looking for fuel-efficiency?
  • Are you looking for high mileage?
  • Will the vehicle be used on-road, off-road, or both?
  • What are the routes going to be like?

“After asking these questions it should be easier to narrow down product options to select the right tire for the customer,” Keller said.

Stevens with TRIB agreed, noting that the relationship between a fleet and a retreader is important. “It’s really about working to understand the types of vehicles and the types of tires they need and matching them,” he said.

Maintain, Maintain, Maintain

Like any other tire, retreads are not maintenance-free. To reap the full value of a tire, fleets should ensure that tire is regularly inspected and operating at peak performance.

“Advanced retread technology is not a substitute for proactive tire maintenance. Routine inspections are also an integral part of every fleet’s tire management program,” Jarrett with Bridgestone said. “Like new tires, retreads should be checked before and after each haul to ensure proper inflation pressure, tread wear and detect any tire damage sooner rather than later. Fleets that practice proper tire care and maintenance help to ensure their casings can be retreaded multiple times, maximizing their tire investment.”

Although inflation is an important factor in any tire maintenance program, it is especially important for retreads. Continental offers a digital tire monitoring platform to view tire pressure and temperature information of the entire fleet. 


“Proper air pressure is the No. 1 way to improve retreadability and tire performance, whether the tire is on its first life or its fourth life,” said Keller of Continental. “Proper tire inflation can provide up to 25% longer tread life and 30% longer casing life, making retreads even more cost-effective.”

In addition, retreading does not have to be a one-time process. 

“It’s important to remember that a premium tire casing can and should be retreaded more than once. Many fleets leave money on the table because they pull a casing out of service too soon,” Jarrett with Bridgestone noted. “Retreading a premium tire two times can keep a tire on the road up to 500% longer than an ultra-low-cost, single-use tire.”

Continental offers similar coverage.

“On most tires, Continental offers a warranty of seven years or three retreads, whichever comes first. This means that tire can have up to four lives, if properly maintained, inspected and serviced,” said Keller.
