Will New Tires Save Fuel?

[VanClara]

New tires consume less fuel than old tires. Reasons: The wider the tire tread, the greater the rolling resistance, and the higher the fuel consumption. The relationship between tread width and rolling resistance. How to choose tires: The higher the tread width, the better the driving stability, but of course, the more fuel it consumes; the narrower the tread width, the lighter the handling and the more fuel-efficient, but stability will be somewhat reduced. A higher aspect ratio means longer sidewalls and better cushioning ability, thus providing better comfort, but weaker grip and control on the road; conversely, a lower aspect ratio means shorter sidewalls and a wider tread, with a larger ground contact area, making the vehicle more responsive to the road and enhancing handling. Generally, the aspect ratio of tires for family cars is between 30% and 80%.
