The 2018 Chevy Express is a versatile and reliable vehicle designed for both commercial and personal use. Proper maintenance is essential for ensuring optimal performance, and one crucial aspect of this maintenance is maintaining the correct tire pressure. Tire pressure affects fuel efficiency, tire wear, and overall safety. Understanding the recommended tire pressure for different trims and engines can help you keep your Chevy Express in peak condition.
Maintaining the right tire pressure is not just a matter of convenience; it’s a safety issue. Underinflated or overinflated tires can lead to poor handling, increased tire wear, and even blowouts. This makes it critical for owners to be aware of the specific tire pressure requirements for their vehicle. Below is a detailed table outlining the recommended tire pressures for various trims and engine configurations of the 2018 Chevy Express.

2018 Chevy Express Tire Pressure Sensor Reset
The tire pressure monitoring system (TPMS) in the 2018 Chevy Express is designed to alert you when tire pressures are too low or too high. If the TPMS light is flashing, it indicates a problem with the system itself, such as a malfunctioning sensor. Resetting the tire pressure sensor can help resolve this issue and ensure that your vehicle operates safely and efficiently. Below are the steps to reset the tire pressure sensor.
Steps to Reset the Tire Pressure Sensor
- Check Tire Pressures: Before resetting, ensure all tires are inflated to the recommended PSI.
- Turn on the Ignition: Insert the key and turn it to the “On” position without starting the engine.
- Locate the TPMS Reset Button: This is often found under the steering wheel or in the glove compartment.
- Press and Hold the Reset Button: Hold the button until the TPMS light blinks three times, then release it.
- Start the Engine: Turn the ignition to the “Start” position and let the vehicle run for about 20 minutes.
- Check for Light: If the TPMS light remains on, repeat the process or consult a professional.
Understanding the Tire Pressure Monitoring System Light
The TPMS light can serve different purposes based on its behavior:
| Light Behavior | Meaning |
|---|---|
| Solid Light | One or more tires are significantly under-inflated. |
| Flashing Light | TPMS malfunction; sensor may need resetting or replacement. |
| No Light | TPMS is functioning correctly; all tires are properly inflated. |
When to Seek Professional Help
If you’ve followed the reset steps and the TPMS light continues to flash, it may be time to consult a professional. Here are some signs that indicate you should seek assistance:
- The TPMS light remains on after resetting.
- You notice unusual tire wear or handling issues.
- There are no visible punctures or damage to the tires.
- The vehicle experiences frequent tire pressure fluctuations.
Maintaining your tire pressure monitoring system is essential for safety and performance. Regular checks and timely resets can prevent more significant issues down the road.
Importance of Maintaining Proper Tire Pressure
Maintaining proper tire pressure is crucial for the overall safety and performance of your vehicle. Under-inflated tires can lead to poor handling, decreased fuel efficiency, and increased tire wear. Conversely, over-inflated tires can cause a harsh ride and reduce traction. Understanding the significance of proper tire pressure can help you avoid costly repairs and ensure a safer driving experience.
Benefits of Proper Tire Pressure
- Improved Fuel Efficiency: Properly inflated tires reduce rolling resistance, leading to better fuel economy.
- Enhanced Safety: Correct tire pressure improves vehicle handling and braking performance, reducing the risk of accidents.
- Extended Tire Life: Maintaining the right pressure minimizes uneven tire wear, prolonging the lifespan of your tires.
- Environmental Impact: Better fuel efficiency means lower carbon emissions, contributing to a healthier environment.
How to Check Tire Pressure
Checking your tire pressure is a simple process that can be done at home. Follow these steps for accurate results:
- Gather Tools: You will need a reliable tire pressure gauge and an air compressor if adjustments are necessary.
- Check When Cold: Measure tire pressure when the tires are cold, ideally before driving or after the vehicle has been parked for a few hours.
- Remove Valve Cap: Unscrew the valve cap from the tire you wish to check.
- Press Gauge onto Valve: Firmly press the tire pressure gauge onto the valve stem until you get a reading. Make sure there’s no hissing sound, which indicates air escaping.
- Read the Pressure: Note the PSI reading on the gauge. Compare it with the recommended pressure found on the driver’s side door jamb.
- Adjust as Necessary: If the pressure is too low, use the air compressor to inflate the tire. If it’s too high, release some air until it reaches the recommended level.
- Replace Valve Cap: After checking and adjusting, replace the valve cap securely.
Useful Tips for Maintaining Tire Pressure
To ensure your tires remain in optimal condition, consider the following tips:
- Regular Checks: Check tire pressure at least once a month and before long trips.
- Monitor Temperature Changes: Be aware that tire pressure can drop in colder weather; adjust accordingly.
- Inspect for Damage: Regularly inspect tires for punctures, cracks, or bulges that could affect pressure.
- Rotate Tires: Rotate your tires every 5,000 to 7,500 miles to promote even wear.
- Use a Quality Gauge: Invest in a good tire pressure gauge for accurate readings.
By keeping your tires properly inflated, you enhance safety, improve fuel efficiency, and extend the life of your tires. Regular maintenance is key to a well-performing vehicle.
