Why does Rolling Resistance matter in the real world?
Some 13% of the power produced by the engine to move a long haul rig along a smooth road at 65 mph is “lost” due to Rolling Resistance. What is it, what causes it, and how can you help to reduce it.
What is Rolling Resistance?
Rolling Resistance is the term used for the energy required to roll a tire over a particular road surface.
It can be viewed as a Parasitic Power Loss, accounting some 13% of the total energy required to move a long haul tractor-trailer combination over a smooth road at 65 mph.
What causes Rolling Resistance?
Rolling Resistance is caused by the following factors
The deformation of the tire in the contact patch and the sidewalls as it rolls (this accounts for some 80% – 95% of Rolling Resistance – Michelin)
Aerodynamic drag of the rotating tire
Friction (microslippage) between the tread and the road surface
Rolling Resistance is also greatly impacted by condition of the road surface.
Why does it matter?
Because it is energy LOST, it is equivalent to a power loss. Power made by the engine is not fully usable, and inhibits forward movement of the vehicle.
Fuel consumption is therefore increased because of this parasitic loss.

Fuel consumption is therefore increased because of this parasitic loss.
How can you reduce Rolling Resistance?
- Keep tires properly inflated. Properly inflated tires minimize deformation of the contact patch and side walls, and keeps energy loss to a minimum.
- Use “green tires”, with rubber compounds and treads designed to minimize this energy loss. As much as 35 HP may be “saved” at 65 mph at 80,000 lb.
- Use of single wide-base tires in place of dual assembly tires. Two dual tires have four sidewalls as opposed to two for a single tire, thus reducing the side wall flex and energy loss.
- Larger diameter tires have slightly lower energy loss due to the fact that there is less bending of the tire as it enters and leaves the contact patch.

121 Ways to Save Fuel: Tires
1) Buy fuel-efficient tires
Getting the right tire at the right wheel position can improve fuel economy by several percentage points.
About 13% of each gallon of fuel consumed goes solely to overcoming rolling resistance. That can vary by the load on the tire, the tread pattern and of course, inflation pressure.
“The relationship between rolling resistance and fuel consumption is about 8:1,” says Rick Phillips, senior director of sales, commercial and OTR products at Yokohama Tire. “An 8% reduction in tire rolling resistance will result in a 1% savings in fuel consumption.”
Various wheel positions have different impacts on fuel economy.
“On a tractor-trailer combination, the steer tires contribute 15-20% to fuel economy, drive tires 30-40% and trailer tires about 40-50%,” says William Estupinan, vice president of technical service for Giti Tire USA. “The first priority for a fleet interested in saving a significant amount of money is to start moving toward fuel-efficient tires for the trailer axles.”
A tight rib pattern, thinner tread — 12/32- to 20/32-inch of tread depth — and advanced compounding make today’s trailer tires very fuel-efficient.
With drive tires, traction and durability are higher on the list of priorities. But traction hasn’t really suffered in a significant way in the quest for lower rolling resistance, manufacturers say.

Major Navistar Fleet, Mesilla Valley Transportation, Adopts eNow Auxiliary Solar System
Mesilla Valley Transportation recently purchased close to 1,000 eNow energy systems for their fleet of Navistar trucks. eNow and Mesilla Valley Transportation (MVT) will showcase the eNow solar auxiliary power system during the NACFE “Run on Less” program taking place September 5 to 24.
This collaboration is the result of eNow’s work in the industry with multiple truck manufacturers and major fleets. As an example, Navistar’s SuperTruck program demonstration vehicle, CatalIST, recently exceeded the improvement goals set by the Department of Energy for the SuperTruck program. CatalIST achieved a freight efficiency improvement of 104% compared to the control vehicle, sipping diesel at 13 MPG. The vehicle also demonstrated 50.5% Brake Thermal Efficiency (BTE) with plans for Navistar to increase that to 55% BTE. As part of its efforts to create the ultimate fuel-efficient truck, Navistar tested eNow’s solar energy system on its SuperTruck at Navistar Proving Grounds.
Simultaneously to Navistar’s testing, Mesilla Valley Transportation (MVT) tested multiple systems on their fleet. “We’re always looking for innovative, more effective and efficient ways to operate,” said Royal Jones, CEO and President of MVT. “Our daily idle time is less than 6% on the whole company fleet and we utilize electric APUs 100%. Over time we had noticed shortened battery life and shortened alternator life due to the demand on batteries and the fact that we run eight batteries.”
The overall results from deployment of the eNow energy system on MVT’s existing Navistar fleet have proven conclusive over diverse road conditions. MVT noted the following results: “Increased daily run time for auxiliary equipment, such as in-cab HVAC; increased battery life from 6 months to 2 years; saved approximately 3 gallons of fuel per day from reduced engine idling; and decreased maintenance cost due to reduction in engine idling."
The results from Navistar Proving Grounds, combined with MVT’s own testing, led to the purchase of the eNow energy systems for the MVT fleet.
"These are exciting times for the transportation industry," says Jeff Flath, President & CEO of eNow. "Everyone is looking at ways to reduce cost, improve efficiency, and help the environment, simultaneously. We are about saving fleets money with our technology first and foremost. However, we also believe that leaving the environment in better shape than we found it is critical as well."

Newest addition to our tow fleet - A & T Road Service
The newest addition to our tow fleet is truck number 32. This is a 2014 Kenworth with a Cummins 500 hp engine and 18-speed transmission. The working end of this mighty tow vehicle is the NRC Quickswap unit with tag axle. This unique design will allow us to tow almost anything on the road. We can now lift up to 20,000 lb steering axle trucks, and also buses and large RV units. The long wheelbase and the tag axle combine to allow us to tow a wide variety of units.
In addition, this truck is well suited for short and long haul jobs. With the sleeper unit, we can tow across the country if needed, or for local jobs the sleeper will accommodate extra passengers. The unit is equipped with state of the art LED lighting to light up the are needed in the night, as well as tool, equipment and parts storage to take care of small repairs, DEF issues and much more.

A & T TOWING SERVICES
North Bay Truck Center and A&T Road Service have added heavy duty towing to our overall list of services. We searched for the most flexible and useful rigs to tow the biggest trucks on the road, along with big buses, and large RV units. See some detail below about our latest truck additions.
Our normal service area covers the best part of the bay area and Sacramento region; however, we now have capability to tow across the country if needed. Our A&T Road Service has expanded so much that we had to add towing to make it even more effective and timely.
Need a tow? Call 1-800-434-1205
