Having a wider tire width can have a significant impact on a car’s fuel economy. The wider the tire, the more area is exposed to the air and the greater the amount of drag is created, which decreases the car’s overall efficiency.
Also, wider tires create more rolling resistance, which also reduces fuel economy. Furthermore, the added weight of the larger tires can also reduce fuel economy, as the engine has to work harder to move the heavier tires. Therefore, it is important to consider the width of the tires when looking to maximize fuel efficiency.
