Ever wondered what low-rolling-resistance tires are and how they can improve your car's fuel efficiency and save you money?
When it comes to driving thrifty, you've likely already learned the tips and tricks to hypermiling, which include accelerating and cruising at low to moderate speeds, changing gears at the right time, and maintaining your tires. It's the combination of all of these factors that result in the best fuel economy for your car, and equipping your car with fuel-efficient tires is another method you can use to even further improve this.
While they can be expensive, low-rolling-resistance or fuel-efficient tires can potentially save you money over the long run, especially if you know how they work.
Rolling resistance is the force required for a car to get its tires moving from a standstill. Low-rolling-resistance tires are engineered to require less force than regular tires to begin moving. Additionally, these tires are developed to minimize the amount of tire flex that occurs between the tire and the tarmac, so less energy is wasted - this means stiffer sidewalls. In some fuel-efficient tires, lighter-weight materials are used to make them, which helps to reduce the amount of friction between the tire and the road surface.
Other differences between regular tires and energy-saving tires are unique tread patterns that allow more efficient rolling. In summary, tires designed to reduce fuel consumption are often lighter in weight, have more rigid sidewalls, and special tread patterns to make resistance to rotation less. The result is lower fuel consumption.
These are ideal for family-friendly SUV vehicles but when it comes to something more purpose-specific, like a Toyota Tundra work truck, you may not want to deviate from the recommended tires which have specific grip levels and are more capable of taking on rougher terrain. In fact, many drivers of these larger vehicles actually choose to upsize their wheels for more off-roading capabilities and load-bearing versatility.

In the American market, some of the more popular low-rolling-resistance tires include:
Factors determining which are the best tires for frugal gas mileage returns include the type of vehicle you'll be using them on, the typical weather conditions of where you use them, and how well you maintain them.
There are several money-saving strategies that shoppers can employ when it comes to buying new tires for their cars, starting with implementing proper tire care:
According to the U.S. Department of Energy, most drivers can achieve up to just 3% of fuel savings with low rolling resistance tires. That may not sound very impressive, but the benefits really rack up over time.
Yes, sometimes low-rolling-resistance tires are made with a harder rubber that can negatively affect the ride quality of the vehicle. LRR tires also tend to have less tread depth than regular tires, which means they wear down quicker.
New tires do help with gas mileage as the fresh tread and lack of wear provide optimal low-rolling-resistance levels and traction, so it requires less effort for your car to send power to the ground. Getting new tires also usually means having your car's wheels aligned and balanced and inflated to the proper pressure levels, al of whichl also contributes to better performance overall.
