2020 Lexus GS Tire Pressure
Where to find the 2020 Lexus GS road-tire pressure (door-jamb label), plus the compact-spare specification with its owner's manual page. Road-tire values are not listed in this manual.
Road tires: use your door-jamb label
This owner's manual doesn't list the road-tire pressures; it points to the Tire and Loading Information label on the driver's door jamb. Use the cold pressures printed there for the front and rear tires. Federal safety standard FMVSS 110 requires that label on passenger vehicles.

Checking your tire pressure
- Check when the tires are cold. Before driving, or after the car has sat for a few hours.
- Use a tire gauge on each valve stem. Include the spare if your vehicle has one.
- Add or release air to match the spec. The tire and loading label on the driver's door jamb lists the pressure for your exact tire size.
Never inflate to the maximum pressure printed on the tire sidewall; that is a limit, not a target.
Confirm with your own manual, dipstick or door-jamb label.
