The miles per gallon, or in short MPG of a vehicle, depends on a variety of factors. In general, the greater is the MPG of an automobile, the better is its fuel efficiency. But does tire size also affect this? It surely does!

This article will explore the impact of 35-inch tires on fuel efficiency to help you have the best driving experience. So stay with us until the end!

Impact of a 35 Inch Tire on MPG

When a user decides to upgrade the tires of his truck to a larger size, such as 35 inches, he should expect a decrease in the miles per gallon covered by the car. This means an inversely proportional relationship exists between the size of the tire and the fuel efficiency of the vehicle.

With every inch of increase in tire size, the fuel efficiency might decrease by 1-2 MPG. And the decrease also depends on what speed the car is traveling at. If the truck is being driven at high speed in an expressway, you can expect a drop in fuel efficiency by 2-4 mpg.

On the other hand, if the truck cruises at an average speed in the city, the drop might be a little less, ranging between 1-2 mpg. In some instances, the vehicle’s torque also plays a role along with the specifications provided by the automobile manufacturer.
