What is the tire pressure for a Lexus GS 350?
The recommended tire pressure for a Lexus GS 350 is 32 PSI (pounds per square inch) for the front tires and 35 PSI for the rear tires. This information can be found in the owner's manual or on the driver's side door jamb sticker of the vehicle.
Understanding Tire Pressure for the Lexus GS 350
Proper tire inflation is crucial for the safe and efficient operation of a Lexus GS 350. The manufacturer-recommended tire pressure ensures optimal handling, fuel efficiency, and tread life. Underinflated tires can lead to increased rolling resistance, reduced fuel economy, and premature wear, while overinflated tires can result in a harsher ride and decreased traction.
Checking and Maintaining Tire Pressure
To ensure the tires on your Lexus GS 350 are properly inflated, follow these steps:
- Check the tire pressure, including the spare, at least once a month and before long trips.
- Use a reliable tire pressure gauge to measure the PSI in each tire.
- Adjust the tire pressure to the recommended levels, which can be found in the owner's manual or on the driver's side door jamb sticker.
- Remember to check the tire pressure when the tires are cold, meaning the vehicle has been parked for at least three hours or driven less than a mile.
Maintaining the correct tire pressure not only improves the performance and safety of your Lexus GS 350 but also helps extend the life of your tires, saving you money in the long run.
Factors Affecting Tire Pressure
Several factors can influence the tire pressure in your Lexus GS 350, including:
- Temperature changes: Tire pressure increases as the temperature rises and decreases as the temperature falls.
- Vehicle load: Heavier loads, such as carrying passengers or cargo, can cause the tires to require higher inflation pressure.
- Driving conditions: Driving on rough or uneven terrain can cause the tires to lose air pressure more quickly.
It's important to regularly check and adjust the tire pressure on your Lexus GS 350 to ensure optimal performance and safety.
Is 40 psi too high for tire pressure?
No, for most cars a tire pressure of 40 psi is too high. You might find 40 psi suitable for some vehicles, especially if they're carrying heavier loads or if the manufacturer's recommendation is close to that figure. However, it's generally too high for most passenger cars, which usually recommend between 30-35 psi.

What is the tyre pressure for a Lexus GS 350?
The recommended tire pressure for a Lexus GS 350 is 33 psi (pounds per square inch) for the front and rear tires, though you should always check the tire placard on the driver's side doorjamb for the exact specifications for your vehicle. It is crucial to check and adjust the pressure when the tires are cold, and to double-check the pressure at least once a month and before long trips.

How to find and adjust tire pressure
- Locate the recommended pressure: Find the sticker on the driver's side doorjamb. This placard lists the recommended cold tire pressure for the specific model and original equipment.
- Check pressure when cold: Before driving, or after the car has been parked for at least three hours, use a tire pressure gauge to check the pressure in all four tires.
- Adjust pressure:
- If the pressure is too low, add air.
- If the pressure is too high, release air.
- Find the reset button: After adjusting the pressure, you may need to reset the Tire Pressure Monitoring System (TPMS). The location of the reset button varies by model year, but it is often near the brake pedal.
- Double-check: After a few minutes of driving, re-check your tire pressures to ensure they have been correctly set.

Important tips
- Never rely on the maximum pressure: The maximum pressure listed on the tire's sidewall is the highest pressure the tire can hold, not the recommended pressure for your vehicle.
- Adjust for load: Carrying heavy loads or towing will require a different pressure, so consult your owner's manual for specific guidelines.
- Tire condition: If you frequently need to add air to a tire, it may have a slow leak and should be inspected for damage.
