Yes to a degree. As the pressure is increased, there is less tire contact with the road surface (grip is reduced accordingly) and gas milaege improves slightly.

No. A car will get better mileage with the correct tire pressure.


Will using a smaller tire size than stock increase gas mileage?

No, it will decrease gas mileage.


Why does the pressure in an automobile tire increase if the automobile is driven for a while?

The tire heats up do to the friction with the road, a heated gas in a set volume will increase in pressure.


Why does air pressure in a cars tire increase after a long drive?

As you drive, the friction of the road and the flexing of the tire increases the tires temperature. When you increase the temperature of a gas in a sealed container the pressure goes up.As you drive, the friction of the road and the flexing of the tire increases the tires temperature.

What is the best tire inflation number for improving gas mileage?

Different size tires require different inflation amounts. You can find the amount of air you need on the side of the tire. To increase gas mileage you should slightly over inflate your tires.

Does tire pressure effect gas mileage?

Yes, definitely. Lower tire pressure increases rolling resistance and hinders fuel economy. Deflate your bike tire by a fair percentage say 50 and drive around, it isn't easy.

Why does the air pressure increase when you pump a tire?

When you pump air into a tire, you are increasing the number of air molecules inside the tire's confined space. As more air is added, these molecules collide more frequently with the tire walls, leading to an increase in pressure. This rise in air pressure is a result of the gas laws, specifically Boyle's law, which states that at a constant temperature, the pressure of a gas increases as its volume decreases. Therefore, the confined volume of the tire limits the space for the air, resulting in higher pressure.


Incorrect tire inflation can adversely affect?

Tire wear, vehicle handling and gas mileage.


Yes you should because when you drive its less chance you will get a flat tire.?

I recommend a highway tire for your best gas mileage. The strength of a tire is referring to the tread size, the larger the tread the larger the tire. Hence, the less gas mileage obtained.
