Not all tires are created equal.
Some tires last longer than others, obviously, but did you know that some tires are designed to improve gas mileage versus other tires?
It's all in the technology.
Take the MICHELIN® HydroEdge® tire, for example. It's the most fuel-efficient tire among standard tires in its category, thanks to MICHELIN® Green X® technology.
The most important gas mileage features in a tire are:
Proper Air Pressure - Under-inflated tires are one of the biggest causes of using excess fuel in the world.
The American Automobile Agency has stated that operating a vehicle with under-inflated tires can result in a 25% reduction in fuel economy.
Tire Construction - The lower the rolling resistance, the less effort from your engine, the better the gas mileage.
This is why passenger tires offer better gas mileage and longer tread life than SUV/Light Truck tires and winter tires, whose heavier tread patterns are designed with maximum traction in mind.
