Driving with low tire pressure is not okay and can be incredibly dangerous. While you might be tempted to "just drive it to the gas station," doing so puts you, your passengers, and other drivers at significant risk. This comprehensive guide will explore the dangers, causes, and what to do if you find yourself with underinflated tires.
What Happens When You Drive with Low Tire Pressure?
Driving on underinflated tires leads to a cascade of negative effects:
-
Reduced Fuel Efficiency: Low tire pressure increases rolling resistance, forcing your engine to work harder and significantly reducing your gas mileage. You'll spend more money at the pump for the same distance traveled.
-
Increased Risk of Blowouts: Underinflated tires are more likely to overheat and fail, leading to a potentially dangerous blowout. This sudden loss of air pressure can cause you to lose control of your vehicle, resulting in an accident.
-
Uneven Tire Wear: Low pressure causes the tire's sidewalls to flex excessively, leading to uneven and accelerated wear. This reduces the lifespan of your tires and can create unsafe driving conditions.
-
Reduced Handling and Braking: Underinflated tires reduce your vehicle's ability to grip the road, making it harder to steer, brake effectively, and maintain control, especially in wet or icy conditions. This significantly increases your risk of an accident.
-
Damage to Wheels and Suspension: The increased flexing and stress on the tires and wheels from low pressure can also damage your vehicle's rims and suspension components, leading to costly repairs.
What are the Causes of Low Tire Pressure?
Several factors can contribute to low tire pressure:
-
Slow Leaks: Punctures from nails, screws, or other small objects can cause slow leaks that may not be immediately noticeable.
-
Temperature Changes: Cold weather causes tire pressure to drop, while hot weather can increase it. Always check your tire pressure when the tires are cold (before driving).
-
Valve Stem Issues: A damaged or worn valve stem can allow air to slowly escape from your tires.
-
Natural Air Loss: Tires naturally lose a small amount of air over time due to permeability.
How Can I Tell if My Tires Have Low Pressure?
While a tire pressure gauge is the most accurate method, you can also look for some visual clues:
-
The Tire Looks Deflated: A visibly flattened or "sagging" tire is a clear indication of low pressure.
-
The Tire Sidewall Feels Softer Than Normal: Gently press on the tire sidewall. If it feels significantly softer than the other tires, it likely has low pressure.
What Should I Do if I Have Low Tire Pressure?
-
Pull Over Safely: Find a safe location away from traffic to stop your vehicle.
-
Do Not Drive on Low Tires: Avoid driving on significantly underinflated tires unless absolutely necessary for a very short distance to a safe location.
-
Check the Tire Pressure: Use a reliable tire pressure gauge to measure the pressure in each tire and compare it to the recommended pressure listed in your vehicle's owner's manual or on a sticker located inside the driver's side doorjamb.
-
Add Air: If the pressure is low, use a portable air compressor or visit a gas station to inflate your tires to the recommended pressure.
-
Inspect for Damage: Check your tires carefully for punctures, cuts, or other damage that might be causing the low pressure.
-
Consider Professional Help: If you're unsure about anything or if you find damage, contact a tire professional for assistance.
How Often Should I Check My Tire Pressure?
It's recommended to check your tire pressure at least once a month, and before long trips. Consider checking them more frequently if you live in an area with extreme temperature fluctuations.
Can I Drive a Short Distance with Low Tire Pressure?
While a very short distance to a safe location might be acceptable, it's generally not recommended. Even a short distance can cause significant damage to your tires, wheels, and suspension. The risks of driving on low pressure tires outweigh the convenience of a short drive.
This information is for general guidance only. Always refer to your vehicle's owner's manual for specific tire pressure recommendations and safety guidelines. Driving safely is paramount; never compromise your safety or the safety of others by driving on underinflated tires.
