Wider tires may appear to be beneficial to your car, but they can actually lead to a decrease in your gas mileage. The broader the tire, the more contact it has with the road, thus creating more drag. This drag causes your car to use more fuel to travel at the same speed compared to when using narrower tires. Additionally, wider tires tend to be heavier, which can cause your car to use more gas when accelerating and when climbing hills. To get the most mileage from your car, choose narrower tires that have a lower rolling resistance.
