What is the rolling resistance of my tires?
Tire rolling resistance is the energy that your vehicle needs to send to your tires to maintain movement at a consistent speed over a surface. The energy loss must be overcome by the vehicle’s engine, which results in wasted fuel.
What is the best low rolling resistance tire?

Do low rolling resistance tires make a difference?
Low rolling resistance tires help save energy by requiring less rolling effort which helps improve fuel efficiency. This minimizes friction, which means less energy is expended and less fuel is consumed.
What is rolling resistance caused by?
The main contributor to rolling resistance is the process known as hysteresis. Hysteresis is essentially the energy loss that occurs as a tire rolls through its footprint. The energy loss must be overcome by the vehicle’s engine, which results in wasted fuel.
What is the benefit of low rolling resistance tires?
Low rolling resistance tires are designed to reduce the energy loss as a tire rolls, decreasing the required rolling effort — and in the case of automotive applications, improving vehicle fuel efficiency as approximately 5–15% of the fuel consumed by a typical gas car may be used to overcome rolling resistance.
How do I know if my tires have low rolling resistance?
How is low rolling resistance achieved?
- Tread design. To understand the influence of tire tread on rolling resistance it’s perhaps easiest to first recognize an inefficient design – off-road tires are a great example.
- Tire tread compound.
- Stiffened sidewalls.
- Smaller tire footprint / contact patch.
- Tire weight reduction.
Are low rolling resistance tires worth it?
Fuel efficient tires have low rolling resistance that require less energy than standard tires to propel them in the direction of travel. The easier it is to roll the tires, the less heat is generated, and the less fuel needed to propel the vehicle. When tires heat up the tread will wear more quickly.
What can increase tire rolling resistance?
Factors that contribute to rolling resistance are the (amount of) deformation of the wheels, the deformation of the roadbed surface, and movement below the surface.
How do you calculate rolling resistance?
A formula for calculating rolling resistance is N = W x V x T / 270 where N. is the horsepower required, W is the weight in kilograms (2.2 lbs = 1.
What do you need to know about low rolling resistance tires?
Originally, low rolling-resistance tires were made with a hard rubber compound and stiff sidewalls to reduce friction and flex. While this approach worked moderately well in reducing friction, using those tires felt like riding on rocks, and they had very little grip.
What are the best tires for gas mileage?
The Bridgestone Ecopia EP422 Plus is another popular model of super fuel efficient tires. According to Bridgestone, it can save you up to 20 miles per tank of gas compared to a typical Bridgestone tire. The Bridgestone Ecopia EP422 Plus is just one of the many Ecopia fuel efficient tire styles.
What is the rolling resistance coefficient?
Rolling resistance coefficient. The “rolling resistance coefficient” is defined by the following equation: C r r {\\displaystyle C_{rr}} is the force needed to push (or tow) a wheeled vehicle forward (at constant speed on a level surface, or zero grade, with zero air resistance) per unit force of weight.
