Low Rolling Resistance Tires: What They Are and Why They Save You Money

by Cerebrum Sensor

Introduction

In the realm of automotive innovation, improving vehicle efficiency has always been a critical part of research and development. Some of the innovations that have revolutionized the automotive industry include electric vehicles, engine stop/start technology, fuel-saving hybrids, and more. At the forefront of this green revolution is the cutting-edge Low Rolling Resistance Tire. Some of the best tire models that boast this fuel-saving technology include the Pirelli Scorpion Verde, Bridgestone Ecopia, Michelin Energy Saver A/S, Firestone Champion Fuel Fighter, and the Dunlop Ensave.


Understanding Rolling Resistance

Engineers have developed a tire that reduces the rolling resistance, which is simply the energy that opposes the motion of the tire as it rolls along a surface. Rolling Resistance originates from the deformation of the tire as it rolls, as well as the internal friction within the tire itself. A tire with high rolling resistance will result in higher energy loss as well as reduced fuel efficiency and increased emissions. A tire with low rolling resistance requires less effort from the engine to start moving, as well as less effort to keep the tires rolling.

Features of Low-Rolling Resistance Tires

Low Rolling Resistance Tires have been crafted with special design features to make this possible. Let's take a look at them.
  1. Tread Pattern: An optimized tread pattern has been formulated for these tires to minimize energy loss and reduce tire deformation, without compromising good traction and handling.
  2. Advanced Rubber: An advanced rubber compound and other materials are combined to minimize internal friction and heat generation, which reduces energy loss.
  3. Reinforced Sidewalls: A stiffer sidewall will allow for less tire deformation, which reduces energy loss
  4. Innovative construction: Silica-based tread compounds, as well as other lightweight materials, are combined to make this a lightweight tire that contributes to better fuel efficiency.

The Benefit
For the casual driver, having Low Rolling Resistance Tires would help them save a few dollars and enjoy having better fuel efficiency. In the case of commercial fleets that are comprised of many heavy-duty vehicles that operate on a strict budget, an investment in low-rolling resistance tires would have a tremendous impact on fuel savings. It is estimated that as much as 30-40% of fuel is used on the highway to overcome tire rolling resistance. When taking into account the weight of commercial trucks and the amount of trucks in certain fleets, it is hard to deny the potential savings.
