Your tires play a major role in your vehicle’s safety, handling, fuel efficiency, and overall performance. But even if your tires look perfectly fine, they may not have the correct amount of air pressure.
For drivers in Lee’s Summit, MO, checking tire pressure is a simple maintenance habit that can help prevent uneven tire wear, improve driving comfort, and prepare your vehicle for changing Missouri weather.At McCarthy Chevrolet Lee’s Summit, we’re answering common tire pressure questions, explaining how to check your PSI at home, and sharing when it may be time to have your tires inspected.
What Is the Correct Tire Pressure for Your Vehicle?
The correct tire pressure depends on your vehicle’s make, model, year, tire size, and loading requirements. Many passenger vehicles recommend pressures in the range of 30–35 PSI, but you should always use the specification for your particular vehicle.The easiest way to find your recommended tire pressure is to check the driver-side doorjamb label. You can also consult your owner’s manual.
Your vehicle’s recommended pressure is usually listed in pounds per square inch (PSI).
Where Can You Find Your Recommended PSI?
Look in these places to find the correct tire pressure for your Chevrolet:- Driver-side doorjamb: Look for the tire and loading information label.
- Owner’s manual: Check the tire and wheel section for recommended pressures and additional guidance.
- Tire Pressure Monitoring System: Your vehicle may display tire pressure information on the instrument panel or infotainment screen, depending on the model and equipment.
How Often Should You Check Your Tire Pressure?
A good rule of thumb is to check your tire pressure at least once a month and before long road trips.You should also check it when there is a significant change in outdoor temperature or when your vehicle’s tire pressure monitoring system alerts you to a potential problem.
In Lee’s Summit and the greater Kansas City area, temperatures can swing significantly between summer and winter. Because tire pressure changes with temperature, your tires may need attention as the seasons change.
Here’s a simple schedule to follow:
- Once a month: Check all four tires, including the recommended pressure for each tire.
- Before a road trip: Verify tire pressure before carrying extra passengers or luggage.
- During seasonal changes: Recheck pressure when temperatures rise or drop substantially.
- When a warning light appears: Check the tires as soon as it is safe to do so.
- After noticing a problem: Investigate a tire that repeatedly loses pressure, looks unusually low, or has visible damage.
How to Check Tire Pressure at Home
Checking your tire pressure takes only a few minutes with a reliable tire pressure gauge.Step 1: Check Your Tires When They’re Cold
For the most accurate reading, check tire pressure before driving or after the vehicle has been parked for several hours.Driving warms the tires and can increase the pressure reading. Don’t let air out of a warm tire simply because the reading is higher than the recommended cold pressure.
Step 2: Find the Recommended PSI
Read the tire information label on the driver-side doorjamb or consult your owner’s manual.Check the recommended pressure for the front and rear tires, since some vehicles specify different pressures.
Step 3: Remove the Valve Stem Cap
Unscrew the small cap from the tire’s valve stem and keep it somewhere safe.Step 4: Use a Tire Pressure Gauge
Press the gauge firmly onto the valve stem until you get a reading. If you hear air escaping, reposition the gauge and try again.Compare the reading with your vehicle’s recommended cold tire pressure.
Step 5: Add or Release Air as Needed
If the pressure is too low, add air in small amounts and recheck the reading.If the pressure is too high and the tire is cold, release a small amount of air and measure again.
Repeat this process until the tire reaches the recommended pressure.
Step 6: Check All Four Tires
Repeat the process for each tire, even if only one tire triggered a warning.Remember to replace the valve stem caps when you’re finished.
Don’t forget the spare tire. If your vehicle has a spare, check its pressure according to the owner’s manual and the tire’s specifications.
What Happens If Your Tire Pressure Is Too Low or Too High?
Incorrect tire pressure can affect how your vehicle handles and how your tires wear over time.Driving With Underinflated Tires
When a tire doesn’t have enough air, it can flex more than intended while driving. This may contribute to:- Increased tire wear, particularly along the outer edges.
- Reduced fuel efficiency.
- Changes in steering response and handling.
- Excessive heat buildup, which can increase the risk of tire failure.
Driving With Overinflated Tires
Overinflated tires can also create problems, including:- Uneven wear, often concentrated near the center of the tread.
- A firmer ride.
- Reduced ability to absorb bumps.
- Changes in traction and handling.
What Does the Tire Pressure Warning Light Mean?
Many modern Chevrolet vehicles have a Tire Pressure Monitoring System (TPMS) that alerts drivers when one or more tires are significantly underinflated.If the warning light comes on, check your tire pressures as soon as you can safely stop. Use a gauge rather than assuming the system tells you the exact pressure.
A TPMS warning doesn’t always identify the cause. A tire may have a puncture, a slow leak, or a pressure change caused by colder weather.
If the warning light flashes before staying on, your vehicle may be indicating a TPMS malfunction. Check your owner’s manual for the correct interpretation and have the system inspected if necessary.
Even when the warning light is off, continue checking tire pressure monthly. The system is not a substitute for regular maintenance.
How Does Missouri Weather Affect Tire Pressure?
Temperature changes are especially important for drivers in Lee’s Summit.As temperatures drop, tire pressure generally decreases. As temperatures rise, pressure generally increases. A commonly used estimate is about 1 PSI for every 10°F change in temperature, although the actual change can vary.
For example, a tire inflated to the recommended pressure during a warm afternoon may read lower after a cold night.
That doesn’t mean you should inflate your tires above the manufacturer’s recommendation in anticipation of colder weather. Instead, check them when cold and adjust them to the recommended pressure as conditions change.
If a tire continues to lose pressure, have it inspected for a puncture, leaking valve, or other issue rather than assuming the weather is responsible.
When Should You Have Your Tires Inspected?
Regular pressure checks are important, but they’re only one part of tire maintenance.Consider scheduling an inspection if you notice:
- A tire that repeatedly loses air.
- Cracks, bulges, punctures, or other visible damage.
- Uneven tread wear.
- Vibrations or changes in handling.
- Frequent TPMS warnings.
- Tires approaching the replacement limits described in your owner’s manual or tire manufacturer’s guidance.
