Running a successful utility fleet operation requires fleet managers to, among other things, stay on top of any and every aspect of the business that will impact total operating costs.

A fleet’s tire program is one aspect that makes a significant impact. According to Gary Schroeder, director of global truck and bus tire business for Cooper Tire & Rubber Co. (http://coopertrucktires.com), tire programs are the second-highest operating cost – behind fuel – for the majority of fleets.

So, what can utility fleets do in an effort to control those expenses?

“Helping fleets understand their total tire operating costs – and the role that tires can play in reducing these costs – is important,” said Dustin Lancy, marketing manager for The Goodyear Tire & Rubber Co. (www.goodyear.com). “Some fleets consider tire price to be the driving factor, but we urge them to look beyond the upfront cost of a tire and instead … optimize the return on their tire investment.”

Focus on What Matters Most
Keeping tire costs in check requires a tire program that includes proper tire selection, timely maintenance and frequent inspections.

Fairfax Water, a utility headquartered in Fairfax, Virginia, maintains a selection of tires and tire/wheel assemblies at each of its maintenance facilities, replenishing as needed. Light-duty tires are mounted and balanced in-house, while the tire/wheel assemblies for the fleet’s larger heavy-duty trucks, trailers and equipment are sent out for servicing.

As a utility fleet manager, you operate perhaps the most diversified vehicle fleet of any business, typically using all weight classes of trucks, from light- to heavy-duty, on the road and off, hauling aerial devices, digger derricks and a slew of other job-specific equipment on good pavement or through fields of debris.

Given these characteristics, getting the best value and performance from your tires may not be rocket science, but it does take planning, smart spec’ing and commitment to a maintenance program, according to tire manufacturers.

A fleet’s first step toward tire value is to determine its goals, said Bill Walmsley, product category manager with Michelin Americas Truck Tires (www.michelintruck.com). What do you want in your tires? Durable, trouble-free service and long, even wear? Additional features? Regardless, selecting the best tire for the application is key. Walmsley suggested that fleets start by looking at the same tire size they currently have on their equipment by wheel position and then explore available options in that size to meet the specific conditions under which the equipment will operate. “This might entail specific load-carrying requirements, weather conditions or environmental issues, such as off-road products or tires which operate well in field or snow conditions,” he said.

Calibrating the balance between load and appropriate tire pressure is critical, but it also is easy since every tire manufacturer publishes load and inflation charts for their tires. The only way to make sure the calibrations are correct is to know the loads being carried and use the charts, Walmsley said.

“Tires are designed and optimized to carry a desired load at a specified pressure. Proper pressure for the maximum load being carried is very important. Underinflation and overinflation for the loads being carried will affect tire and casing life and performance,” Walmsley said.

For utility fleets, being able to travel across hazardous terrain – such as storm-impacted areas covered in branches, glass and other debris – is a must. Self-sealing tires can be a great asset during these times, allowing vehicle operators to continue driving even after a tire is punctured.

How do self-sealing tires work? Each tire contains an extra layer comprised of a sticky substance that covers the inside of the tire from one shoulder to the other. As a puncture occurs, the substance automatically seals the hole, staving off a flat tire. For instance, DuraSeal Technology developed by The Goodyear Tire & Rubber Co. (www.goodyear.com) seals punctures up to a quarter-inch in diameter in the repairable area of the tread. And as long as the sidewalls aren’t punctured, drivers can continue operating their vehicles indefinitely. In cases where tire repair or replacement is necessary, self-sealing technology gives drivers time to navigate to a safe place where the work can be done.

Overall, self-sealing tires offer both safety and response-time benefits to utility fleets, helping to ensure that crews can reach isolated areas to restore power to customers without worrying as much about getting a flat tire and the additional man hours such a situation can require.

What if tires could inflate themselves and maintain optimal pressure at all times, with no human intervention required? How much of an impact could that make on fuel efficiency, tire life cycle, driver safety and a fleet’s bottom line?

New self-inflating tire technologies being developed today may provide a glimpse into future possibilities.

Effective management of tire costs is more important now than ever and will continue to grow in importance, but if you are not able to accurately measure what your fleet spends on tires, there is no way you will be able to manage those expenses. Unfortunately, many fleets have not initiated a comprehensive tire management program, nor do they accurately know the expense they incur for tires.

Who gets utility trucks that have been immobilized by tire problems up and running again so utility response crews can resume their important work of restoring gas, electricity and other services following severe weather incidents?

A primary concern of every fleet professional is the safe operation and stopping ability of the vehicles in his fleet. A truck’s ability to stop, of course, depends on the condition and quality of its braking system, particularly its brakes’ friction material. The friction material used in truck brakes has changed a great deal over the last few decades and continues to change. As an integral part of the braking system, friction material must be chosen to provide the stopping power necessary in a truck’s specific application. This is especially true for commercial vehicles since any given truck model may be put into a wide range of applications. Light-duty vehicles, however, may well benefit from the use of other-than-normal friction material. Consider, for example, police cruisers that may be used in high-speed pursuits with heavy braking demands.

Tires are valuable and costly assets. An effective tire maintenance program can result in reduced tire costs. Some of the best resources for utility fleets are available from suppliers.

Introduced three years ago, the Goodyear fleetHQ Solution Center combines emergency road services with a portfolio of business solutions. Included are online information systems providing 24/7 access to service in progress, retread history, repair data and tire purchase history.
