Imagine the frustration of a retread tire vendor. He or she has proven money-saving products, yet half the industry won’t even look at them because of a bad experience they had 20 years ago with maybe a poor quality and probably poorly maintained retreaded tire. What if some of the largest and most sophisticated fleets in the country took that approach? Can you imagine UPS or Ryder, for example, not using retreads?

Scott Perry, vice president of supply management and fleet management solutions at Ryder System, says the company has about 1.25 million tires on the road on any given day, and a significant portion of those are retreads.

“In a full-service lease, we carry the burden of all the maintenance costs including the tires,” Perry says. “It’s our call all the way, so we try to optimize uptime and reliability as well as the best possible operating expense so we can be as competitive as possible in the marketplace. Retreads allow us to do that in the right application.”

Perry has probably had a few bad experiences with retreads over the years, but the same could be said for new tires. For him, the reliability and value of retreads are no longer in question.

“We have a vested interest in providing our customer with reliable tires,” he says. “We’re careful not to undermine those objectives with questionable tires. We don’t take any shortcuts there.”

Despite success stories like that reported by Ryder, some misconceptions about retreads still exist. These myths are often based on bad, and sometimes severely outdated, information, says Todd Labbe, general manager, commercial retread, Goodyear.

“In the past, there might have been a perception among some fleets that retreads are ‘low-quality’ options,” he points out. “Retreads are more technically advanced than ever, and that goes for both tread rubber and the retreading process itself. Goodyear’s retread technology evolves with our new truck tire technology.”

With today’s sensitivity to rolling resistance, tread compounding has really come into its own. About 60% of a tire’s rolling resistance comes from the casing, about 40% from the tread. Retreaders can’t do much about the casings they have to work with, but, according to Guy Walenga, Bridgestone’s director of engineering for commercial products and technologies, rubber compounding is where the magic is today.

“When we’re building a new tire, we’re using maybe 14 different compounds together, and that has to be molded and cured, and comes out as a viable tire,” Walenga says. “With retreads, you’re able to isolate just the tread and just its performance requirements, so you can use different compounds to get similar performance. There is also a different set of technical specifications required for compounds on a retread versus compounds that need to blend overall on a new tire.”

And the other advantage to a retreaded low-rolling-resistance tire is the tread tends to be a couple of 32nd’s shallower than a comparable new tire.

“That’s gives you a bit of an advantage right from day one,” Walenga notes. “The tread may look the same; for example, our Ecopia M835 has the identical tread pattern as the Bandag B835, but the compounding will be different. Along with the shallower tread, you’re going to see improved fuel economy sooner than with the thicker tread on a new tire.”

Can Small Fleets Play, Too?

There’s a perception, perhaps grounded in some fact, that retreading isn’t popular with small fleets. David Stevens, managing director of the Tire Retread & Repair Information Bureau, thinks that in the absence of data, smaller fleets and independent drivers tend to hold onto some of the old misconceptions and myths about retreaded tires.

“Larger fleets often have set up sophisticated tire management programs and have carefully measured the benefits that retreaded tires bring to them in terms of overall lower cost per mile. But, as one attendee at this year’s Mid-America Trucking Show told me about larger fleets and testing, ‘I can’t do all the testing they do on tires, but I can sure learn from the testing they’ve done and apply it to my business.’”

One thing that could be keeping some small fleets out of the retread game is a casing inventory. The big fleets can ship a truckload of casings to a retreader at one time. Small fleets need a place to store them, they can ill-afford to have dozens of non-utilized assets sitting around, and the prospect of getting a decent credit for their casings could also be a factor.

“All fleets, regardless of size, are looking for ways to save money and retreads still offer that opportunity,” says Philip Boarts, Michelin's retread product category manager. "For some very small fleets that don’t have a tire/retread inventory, due to the shortage of casings during the past couple years, availability of caps and casings has been limited, which might have forced these fleets into buying more new tires.”

Each fleet has its specific requirements of what it is looking for in a retread, Boarts adds. “It depends on the fleet’s type of operation, casing management ability, turnaround time, level of dealer service, on-line reporting needs, and fleet location. There’s a lot to consider when determining what part of a fleet’s replacement program will be in the retread area.”

In addition to the tires themselves, retreaders are constantly improving their procedures and adding services, including automated tracking systems to simplify tire management.

“Goodyear’s GTracs system, which is available through the Goodyear Authorized Retread network, uses bar codes to track the progress of a casing through the retread process,” says Labbe. “After a tire has been retreaded, GTracs provides fleets with data about their retreads in the form of easy-to-understand reports.”

Ironically, this is just the kind of tracking capability some smaller fleets lack that would help them prove the ROI of a retreading program.

“The larger fleets know retreads will save at least 50% over the acquisition cost of new tires,” says Harvey Brodsky, managing director of the Retread Tire Association. “On top of that, when you have an adjustment rate as good as or better than that of a new tire, they’d have to be out of their minds not to use retreads.”

But old stereotypes are hard to kill, including that of crummy retreads, which probably dates back to World War II when rubber was in very short supply and retreaders had little to work with but the dregs.

Today’s adjustment rates are comparable to new tires. Treads are available in so many patterns and compounds that fleets can literally spec their tires by wheel position and application. And just like new tires, one of the only threats to the product’s ROI is underinflation. In fact, tire management skill may be one of the few advantages big fleets have over the small ones when it comes to retreads — heck, tires in general. They probably have someone on the payroll looking after that.

    Under inflation was mentioned in this article. What PSI is considered underinflated? Recent articles quote the tire industry as saying most tires are over inflated. They even recommend 85-90 PSI with the heaviest loads carried on tires. Can someone give readers a simple answer?

  2. 2. Gil Justiss [ July 09, 2014 @ 08:25AM ]

    A simple answer is hard to come by. Under inflation is a relative term. It cannot be defined as a specific pressure for all tires or even tires of the same type, size, and load range. Reason being is that the ideal inflation pressure for a tire or set of tires varies with the amount of load it is carrying. Even the Fed's and Commercial Vehicle Enforcement Officers / Inspectors agree that "Under Inflation" is term / item that needs to have it's definition cleaned up in their world too. Most, if not all of the major tire manufacturers have published tables available on line that define recommended tire inflation pressures with respect to the amount of load the tire is carrying. With Firestone the chart is called "Load and Inflation Tables". I utilize this chart in our fleet and have had excellent tire wear results. Typically we run 80 PSI in 295/75/22.5 G tires on tandem drives at 34,000 lbs total for both axles. This pressure is actually slightly higher than the chart recommends, but I have found that I get more even tread wear across the face of the tires at this pressure. Steer axle tires are the only place that we inflate tires to the tire manufacturers max inflation pressure printed on the tire side wall. We have some lightly loaded tires of the same size that run on trailers that we only inflate to 70 PSI. Its all relative to the load applied to the tire. Do some research on the tire manufactures sites and talk to some reputable tire stores that do a lot of big rig / fleet service. Automatically inflating a tire to the max load pressure stated on the side wall is old school and will give you shortened tread life, poorer traction, and a harsher ride. Research pays. Good luck.

    I have tried retreads several times over the last 12 years. I have had a 25% failure rate. During the same time I have had a 0% failure rate on new tires. By failure I mean tires separating or blowing out without being punctured by something.

    Tire inflation well explained by Gil. Your tire performance will improve if you follow his advice. I'm on the tire sales side so it is nice to hear this response from the fleet side. I have been trying to convince my fleet customers of this for years. It normally meets with skepticism. Thanks Gil.

    25% failure rate? So on a set of 8, you lose two tires at any given time along their useful life? No thanks, I'm guessing the downtime, damage to any other components like flap hangers, lines, bodywork, fenders, etc., caused by a blowout or separation would eat any "savings" you thought you were getting by gambling on retreads. I've NEVER encountered a premature tire failure caused by something other than a puncture on any virgin set of tires in 21 years of running them. Price em dirt cheap, and MAYBE I'd consider them. Wait, no I wouldn't....
