The 2007 Lexus RX 350 is a luxury crossover SUV known for its comfort, reliability, and advanced features. One crucial aspect of vehicle maintenance that often gets overlooked is tire pressure. Proper tire pressure is essential for optimal vehicle performance, fuel efficiency, and safety. Understanding the recommended tire pressure for your specific trim or engine variant can help ensure that your vehicle operates smoothly.
Maintaining the correct tire pressure not only extends the life of your tires but also enhances overall driving safety. Under-inflated tires can lead to poor handling, increased tire wear, and reduced fuel efficiency. Conversely, over-inflated tires can cause a harsher ride and increase the risk of tire blowouts. Below is a detailed table outlining the recommended tire pressure for different trims and engine options of the 2007 Lexus RX 350.

2007 Lexus RX 350 Tire Pressure Sensor Reset
If the tire pressure monitoring system (TPMS) light on your 2007 Lexus RX 350 is flashing, it indicates an issue with the tire pressure sensors. This can occur after a tire change, rotation, or if the tire pressure has been significantly altered. Resetting the tire pressure sensor is essential to ensure accurate readings and to turn off the warning light. Below are the steps to reset the TPMS on your vehicle.
Steps to Reset Tire Pressure Sensor
- Check Tire Pressure: Before resetting the sensor, ensure that all tires are inflated to the recommended pressure listed in the owner’s manual or on the driver’s side door jamb.
- Turn on the Ignition: Insert the key into the ignition and turn it to the “On” position without starting the engine.
- Locate the TPMS Reset Button: This button is usually located beneath the steering wheel or on the dashboard.
- 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 off and then start the engine. The TPMS light should turn off if the reset was successful.
Troubleshooting Flashing TPMS Light
If the TPMS light continues to flash after following the reset procedure, consider the following:
- Check for Tire Damage: Inspect the tires for any visible damage or punctures.
- Examine the Sensors: The tire pressure sensors may be malfunctioning or need replacement.
- Battery Issues: In some cases, the battery in the tire pressure sensor may be dead.

Importance of Maintaining Proper Tire Pressure
Maintaining the correct tire pressure is crucial for the overall performance and safety of your vehicle. Properly inflated tires ensure better handling, improved fuel efficiency, and increased tire longevity. Under-inflated tires can lead to excessive wear, reduced traction, and a higher risk of blowouts. Conversely, over-inflated tires can cause a harsh ride and lead to uneven wear patterns. Here’s why keeping your tires at the right pressure is essential:
Benefits of Proper Tire Pressure
- Enhanced Safety: Proper tire pressure helps maintain optimal contact with the road, improving traction and reducing the likelihood of accidents.
- Improved Fuel Efficiency: Tires that are inflated to the correct pressure reduce rolling resistance, leading to better fuel economy.
- Extended Tire Life: Correct inflation minimizes uneven wear, allowing your tires to last longer and saving you money in the long run.
- Better Ride Comfort: Properly inflated tires provide a smoother ride, enhancing overall driving comfort.
How to Check Tire Pressure
Checking your tire pressure is a simple process that can be done at home or at a gas station. Here’s how to do it:
- Gather Your Tools: You will need a reliable tire pressure gauge. Digital gauges are often easier to read, but manual gauges work just as well.
- Check Tire Pressure When Cold: For the most accurate reading, check the tire pressure when the tires are cold, ideally before driving or at least three hours after driving.
- Remove Valve Cap: Unscrew the valve cap from the tire you wish to check.
- Press Gauge onto Valve Stem: Firmly press the tire pressure gauge onto the valve stem to get a reading. Ensure there’s no hissing sound, which indicates air escaping.
- Read the Gauge: Check the reading on the gauge and compare it to the recommended tire pressure for your vehicle.
- Replace Valve Cap: After checking, replace the valve cap securely to prevent dirt and moisture from entering.
Useful Tips for Maintaining Tire Pressure
To keep your tires in optimal condition, consider the following tips:
- Regular Checks: Check your tire pressure at least once a month and before long trips.
- Monitor Temperature Changes: Tire pressure can fluctuate with temperature changes. Check your tires more frequently during seasons with extreme temperatures.
- Use a Reliable Gauge: Invest in a good-quality tire pressure gauge for accurate readings.
- Know Your Recommended Pressure: Familiarize yourself with the recommended tire pressure for your specific trim, which can usually be found in the owner’s manual or on the driver’s side door jamb.
- Inspect Tires Regularly: Look for signs of wear, damage, or punctures, and address any issues promptly.
By adhering to these practices, you can ensure that your 2007 Lexus RX 350 maintains optimal performance, safety, and efficiency on the road.
