How to Compare Rolling Resistance of Tires

Rolling resistance is a measure of how much energy is required to keep a tire rolling. The lower the rolling resistance, the less energy is required and the more efficient the tire. There are a number of factors that contribute to rolling resistance, including tire size, tread design, and construction.

Comparing the rolling resistance of tires can be helpful in choosing the most efficient option for your vehicle. There are a few ways to compare the rolling resistance of tires. One method is to look at the published data from the manufacturer.

This data can be found on websites or in brochures. Another way to compare tires is to test them yourself. This can be done by measuring your fuel economy with different tires on your vehicle.

  • Research the different types of tires available
  • Decide which type of tire you would like to compare the rolling resistance of
  • Purchase your chosen tires
  • Make sure to get the same model and size for each tire
  • Install the tires on your vehicle
  • If you are not comfortable doing this, take it to a professional mechanic
  • Drive your vehicle as usual for at least a week, making sure to take note of how each tire feels while driving
  • After a week or more, check the tread depth of each tire using a tread depth gauge
  • The deeper the tread depth, the better grip the tire will have on the road, meaning less rolling resistance

Understanding Rolling Resistance!

How Do You Measure Tire Rolling Resistance?

Rolling resistance is the force required to keep a tire rolling at a constant speed. It is caused by the deformation of the tire as it rolls and by friction between the tire and the road surface. The amount of rolling resistance depends on the type of tire, the inflation pressure, the load on the tire, and the surface roughness of the road.

The most common way to measure rolling resistance is with a rolling resistance tester (RRT). This device consists of a platform that supports the wheel of a vehicle, and a roller that presses against the tread of the tire. The RRT measures the force required to rotate the roller at a constant speed.

This force is then divided by the weight of the vehicle to give the Rolling Resistance Coefficient (RRC). There are two main types of RRTs: those that use air pressure to press againstthe tread (air-bearing RRTs), and those that use a mechanical brake systemto press againstthe tread (mechanical RRTs). Air-bearing RRTs are more accurate but they are also more expensive.

Mechanical RRTs are less accurate but they are less expensive. To get an accurate measurement of rolling resistance, it is important to use an RRT that has been calibrated for accuracy. It is also important to make sure that all four tires are tested under identical conditions (load, inflation pressure, etc.).

Which Type of Tire Has the Lowest Rolling Resistance?

There are a few different types of tires that have been designed to minimize rolling resistance. These include “low rolling resistance” (LRR) tires, “fuel efficient” tires, and “green” tires. LRR tires are made from a special type of rubber compound that is designed to reduce energy loss as the tire rolls.

This results in less fuel being required to maintain a given speed, and thus these tires can help to improve fuel economy. Fuel efficient tires are also designed to minimize rolling resistance, but they typically use a different type of rubber compound than LRR tires. Fuel efficient tires often sacrifice some traction and grip in order to achieve their lower rolling resistance.

Green tires are those that have been specifically designed to be environmentally friendly. They may use recycled materials in their construction, and they often have low rolling resistance as well.

How Much Difference Do Low Rolling Resistance Tires Make?

If you’re looking to improve your fuel economy, one of the most effective things you can do is upgrade to low rolling resistance tires. These tires are designed to minimize the amount of energy lost as heat, which means they require less effort for your car to move forward. As a result, you’ll see improved gas mileage and reduced emissions.

While the benefits of low rolling resistance tires are clear, it’s important to note that they may not be right for everyone. If you frequently drive in cold weather or on rough roads, traditional tires may provide better traction and durability. And because low rolling resistance tires tend to be made with softer compounds, they may wear out more quickly than regular tires.

Still, if saving money at the pump is a priority, low rolling resistance tires are definitely worth considering. You may not notice a huge difference in performance, but over time, the savings can add up significantly.

What Does Higher Rolling Resistance Mean?

Rolling resistance is the force that resists the motion of a tire rolling on a road. It is caused by deformation of the tire as it rolls, and by friction between the tire and the road surface. The higher the rolling resistance, the more force is required to keep the tire moving.

This can reduce fuel economy and increase emissions from vehicles.

How to Identify Low Rolling Resistance Tires

When it comes to your car’s fuel economy, one of the key factors is the rolling resistance of your tires. Low rolling resistance tires can improve your car’s fuel efficiency by up to 5%. So how do you identify low rolling resistance tires?

There are a few things to look for when you’re trying to identify low rolling resistance tires. First, check the sidewall of the tire for a special label or logo. This will usually be from the manufacturer and will indicate that the tire has been designed for low rolling resistance.

Next, take a look at the tread pattern. Low rolling resistance tires typically have shallower tread patterns and fewer grooves than regular passenger car tires. This helps reduce the amount of energy required to roll the tire forward.

Finally, check the construction of the tire. Low rolling resistance tires often have stiffer sidewalls and more densely packed treads. This helps them maintain their shape under load and reduces energy loss as heat.

If you’re not sure whether a particular tire is low rolling resistance or not, ask your local service station or tire dealer for more information.

Tire Rolling Resistance Calculator

If you’re looking to calculate the rolling resistance of your tires, there’s a handy tool for that! The Tire Rolling Resistance Calculator can be found at https://www.tirerollings This calculator allows you to input the following variables:

* Tire width * Tire height * Rim diameter

* Rolling radius

Are Low Rolling Resistance Tires Worth It

As a driver, you are always looking for ways to save money. One way to do this is to buy low rolling resistance tires. But are they really worth it?

To answer this question, we need to understand what rolling resistance is. Rolling resistance is the force that a tire exerts on the ground as it rolls. This force slows down the vehicle and wastes fuel.

So, low rolling resistance tires have less of this force, which means they use less fuel and can help you save money. Now that we know what rolling resistance is, let’s look at how much money you can actually save by using low rolling resistance tires. The U.S. Department of Energy estimates that drivers can save about 3% on fuel costs by using these tires.

This might not seem like a lot, but it can add up over time! And if you drive a lot, the savings could be even greater. So, if you’re looking for ways to save money on your car expenses, consider switching to low rolling resistance tires.

They may not provide a huge savings immediately, but over time they can really add up!


When it comes to your bike, the tires you choose can have a big impact on your ride. Not all tires are created equal, and one of the key ways they differ is in their rolling resistance. Rolling resistance is basically how much force is required to keep a tire moving forward.

A tire with high rolling resistance will require more effort to keep moving, while a tire with low rolling resistance will roll more easily. If you’re trying to compare different tires, knowing their rolling resistance can be helpful in making a decision. There are a few different ways to measure rolling resistance.

One common method is called the coast-down test. To do this test, you’ll need a level stretch of road and a way to measure speed and distance traveled. Start by riding your bike at a constant speed until it’s up to cruising speed, then let go of the pedals and coast for about 15 seconds.

Measure the distance you travel during that time, then divide by 15 to get your average coasting speed. The formula for calculating rolling resistance from this number is: Rolling Resistance = (Coasting Speed / Crr) x 9.80665

where Crr is the coefficient of rolling friction (usually given in units of percentage).
