Elements That Influence the Rolling Resistance of Vehicle Tires

Tire Manufacturing Company A tire’s rolling resistance is the physical drag it exerts when in motion. The rolling resistance of your tires significantly affects your vehicle’s fuel economy and increase greenhouse emissions. Reducing your tire’s rolling resistance ultimately enhances your vehicle’s fuel economy and reduces pollution.

Lowering rolling resistance and still maintaining dependable tire traction as well as extended tread wear is a delicate balancing act. This is however now a reality with the SmartWay tires program. Here are the key elements SmartWay tire manufacturers focus on in their tires to achieve this.

Tire Inflation

If your tires have low inflation based on your wheel load, you get significant sidewall distortion of your tires — commonly known as tire deflection.

This results in more heat and energy generation and hence considerable rolling resistance. SmartWay tires, when inflated according to the manufacturer’s instructions and used on their specified axle positions, have reduced tire deflection.

Tread Compounds

The two categories of tire tread compounds include low and high hysteresis rubber. Hysteresis indicates the energy absorbed when the rubber is stretched, and then released on its relaxation.

SmartWay tires use low hysteresis tread compounds, which have low energy loss and are more resilient compared with the high hysteresis compounds.

Tread Design

Your tires’ tread design determines its energy and heat buildup. SmartWay tire treads incorporate narrow groove widths, few grooves, and ribbed grooves. These tread designs make your tires efficient by reducing their rolling resistance.

EPA launched the initiative in 2004, and it is more of a certification rather than a brand. You will thus get a lot of tires on the market touting as SmartWay tires. Before investing in them for your vehicle or dealership, ensure the tires incorporate the above three elements. This is the best way you can be sure you are getting quality for your clients and vehicles.
