Proper tire pressure is often overlooked, but it plays a major role in your vehicle’s performance, fuel economy, and safety. At DM Motorsports in Midland Mint Hill, NC, we frequently see vehicles suffering from premature tire wear, poor gas mileage, and even increased stopping distances—all because of incorrect tire pressure.

Why Tire Pressure Matters

Tires are your car’s only contact with the road. When their pressure is off—even slightly—it affects how your car handles, brakes, and uses fuel.

Underinflated tires create more rolling resistance, meaning your engine has to work harder and burn more fuel.
Overinflated tires reduce traction and increase the risk of a blowout by concentrating pressure on the center of the tread.

Fuel Efficiency: Save Money at the Pump

According to the U.S. Department of Energy, you can improve gas mileage by up to 3% just by keeping your tires properly inflated. While 3% might sound small, it adds up:

You’ll save money on gas over time.
Your engine won’t have to work as hard, reducing wear.
Your carbon footprint decreases with improved efficiency.

Tire Pressure & Safety

Incorrect tire pressure can directly affect:

Braking distance – underinflated tires take longer to stop.
Cornering stability – poor pressure leads to poor grip.
Hydroplaning risk – overinflated tires can reduce water channeling.

In emergency situations, having properly inflated tires can be the difference between stopping in time and getting into an accident.

How to Check and Maintain Tire Pressure

It’s easier than you think:

Use a digital or dial gauge – keep one in your glovebox.
Check tires when cold – pressure increases with heat.
Follow the manufacturer’s PSI – not the number on the tire, but the one listed on your driver-side door frame or manual.
