What is the benefit of low rolling resistance tires?
Low rolling resistance tires can be much more fuel-efficient tire than conventional tires. The U.S. Department of Energy has done research that shows that utilizing low rolling resistance tires can have as much as a 10\% fuel savings impact for drivers. However, for most drivers, the fuel savings is around 3\%.
Is rolling resistance Good or bad?
Engineers have several options for squeezing every bit of rolling resistance out of a tire. Such tires are good for grip but bad for fuel economy, tire life and road noise.
Is miles per gallon a function?
MPG, or miles per gallon, is the distance, measured in miles, that a car can travel per gallon of fuel. MPG is also the primary measurement of a car’s fuel efficiency: The higher a car’s MPG, the more fuel efficient it is.
What does rolling resistance have to do with tire performance?
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.
Do low rolling resistance tires make a difference?
Industry studies show that a 10 percent drop in rolling resistance equates to about a 1 percent improvement in fuel economy. It might not seem like a big difference, but fuel-economy gains are hard to come by. You can grab that advantage by making an informed tire purchase.
What’s the best low rolling resistance tires?

What difference does rolling resistance make?
“It will vary depending on the tyre, pressure, tarmac and so on, but at typical road bike speeds aerodynamic drag might account for 70\% of the effect holding you back, with about 20\% down to rolling resistance. All other factors – like your chain rubbing, the bearings – might be only 10\%.
Why is rolling resistance bad?
That’s a lot of heft to move. But overcoming the tire “rolling resistance coefficient” soaks up an estimated 4-7\% of your vehicle’s energy depending on the driving conditions. Tire rolling resistance is also responsible for as much as 4\% of the world’s carbon-dioxide emissions, according to Michelin.
How many miles can 1 gallon of gas take you?
50
You would need to divide 1000 miles by 50 gallons of gas. That would equal 20; therefore, you traveled 20 miles for every 1 gallon of gas. Your gas mileage would be 20 mpg (miles per gallon).
How do rolling resistance tires compare?
A tire with an index rating of 95 would offer 5\% less rolling resistance than the baseline tire. Conversely, a tire with a 110 rating would have 10\% more rolling resistance than the baseline tire. Depending on the host of the comparison tool, the number might reflect rolling resistance or fuel efficiency.
Is Michelin Defender low rolling resistance?
The Defender has a 90,000-mile/6-year treadlife warranty, and replaces the previous Harmony and HydroEdge series. Michelin says the tire’s silica-based compound offers good all-season grip and stopping performance, while also providing low rolling resistance for higher efficiency and longer service.
