Rolling resistance is the impact the road has on the tires, and how it affects drivability. If you change the features (size and width) of your tires, it will then influence the interaction it has with the road; thus affecting the gas mileage. This is where tire width can begin to influence gas mileage. Many people believe by changing the height of a carâs tires, they can increase its fuel economy.
Yes, adding a turbo to increase fuel mileage may seem a little backward, but you'll see the logic in a moment. Obviously, fabricating a twin-turbo system is beyond the scope of a 700-word article, so if you don't have sufficient fabrication skills then enlist the services of someone who does.he end result will be greater fuel efficiency and stability at highway speeds. The F-250 comes with 8.3 inches of ground clearance stock, so even after installing the 2.5-inch shorter tires you can still lower it by about two inches while maintaining a reasonable four inches of ground clearance.
