33-inch tires can have an impact on gas mileage. The larger the tire, the more resistance it will create as it rolls, leading to a decrease in fuel efficiency. Additionally, the increased weight of the tires can add to the strain on the engine, further decreasing fuel economy. However, with the right tires and the correct air pressure, 33-inch tires can be used with minimal impact on fuel economy. It is important to do research and find the right tire for your vehicle to ensure the highest possible gas mileage.
Narrower tires can potentially increase the gas mileage of your car. This is because a narrower tire has less rolling resistance, meaning it takes less energy to keep it moving. Additionally, narrower tires are more aerodynamic, reducing drag and allowing your car to move more efficiently. However, narrower tires may not be suitable for driving in snow or on rough terrain, so it's important to consider the type of terrain you typically drive on before investing in a set of narrower tires. Ultimately, it's possible that narrower tires can help you save money on gas, but it's important to weigh the pros and cons of narrower tires before making a decision.
