Tesla Model S: Displaying Tire Pressures

Display tire pressures on the touchscreen by touching Controls > Service. The pressure of each tire displays in the visualization of your Model S, in addition to what time your tire pressures were last measured. You can choose whether you want to display tire pressures using Bar or PSI by touching Controls > Display > Tire Pressure. The touchscreen also displays your vehicle's recommended cold tire pressures so you can easily determine how much to inflate your tires.

NOTE: You may need to drive briefly before the visualization displays the tire pressure values.

Maintaining Tire Pressures

Keep tires inflated to the pressures shown on the Tire and Loading Information label, even if it differs from the pressure printed on the tire itself. The Tire and Loading Information label is located on the center door pillar and is visible when the front door is open.

Tire Care and Maintenance

The Tire Pressure indicator light on the instrument panel alerts you if one or more tires is under- or over-inflated.

The Tire Pressure indicator light does not immediately turn off when you adjust tire pressure. After inflating the tire to the recommended pressure, you must drive over 15 mph (25 km/h) for a short amount of time to activate the Tire Pressure Monitoring System (TPMS), which turns off the Tire Pressure indicator light.

If the indicator light flashes for one minute whenever you power on Model S, a fault with the TPMS is detected (see TPMS Malfunction).

NOTE: Your vehicle's tire pressures will drop in cold ambient temperatures. If the TPMS indicator light appears, inflate the tires before driving. The tires will lose one PSI for every 10º F (6º C) drop in outside temperature. Proper tire pressures help protect tires from potholes and improve range when properly inflated.

WARNING: Under-inflation is the most common cause of tire failures and can cause a tire to overheat, resulting in severe tire cracking, tread separation, or blowout, resulting in unexpected loss of vehicle control and increased risk of injury. Under-inflation also reduces the vehicle's range and tire tread life.

WARNING: Check tire pressures using an accurate pressure gauge when tires are cold. It takes only about one mile (1.6 km) of driving to warm up the tires sufficiently to affect tire pressures. Parking the vehicle in direct sunlight or in hot weather can also affect tire pressures. If you must check warm tires, expect increased pressures. Do not let air out of warm tires in an attempt to match recommended cold tire pressures. A hot tire at or below the recommended cold tire inflation pressure is dangerously under-inflated.

Checking and Adjusting Tire Pressures

Follow these steps when tires are cold and Model S has been stationary for over three hours:

1. Refer to the Tire and Loading Information label located on the driver's center door pillar for the target tire pressure.

2. Remove the valve cap.

3. Firmly press an accurate tire pressure gauge onto the valve to measure pressure.

4. If required, add or remove air to reach the recommended pressure.

NOTE: You can release air by pressing the metal stem in the center of the valve.

5. Re-check pressure using the accurate tire gauge.

6. Repeat steps 3 and 4 as necessary until the tire pressure is correct.

7. Reinstall the valve cap to prevent dirt from entering. Periodically check the valve for damage and leaks.


     Inspecting and Maintaining Tires

    Regularly inspect the tread and side walls for any sign of distortion (bulges), foreign objects, cuts or wear. WARNING: Do not drive Model S if a tire is damaged, excessively worn, or inflated to

     Replacing Tires and Wheels

    Tires degrade over time due to the effects of ultraviolet light, extreme temperatures, high loads, and environmental conditions. It is recommended that tires are replaced every six years, or sooner

     Tire Pressure Monitoring

    Each tire should be checked monthly when cold and inflated to the recommended pressures that are printed on the Tire and Loading Information label located on the driver's door pillar (see Maintaini


     Bushing Installation, Front Motor Mount

    Use brake cleaner to clean the threaded rod and the nut bearing assemblies. Use 3M Spray Lube 08878 or equivalent to lubricate the threaded rod and the nut bearing assemblies. Slide the bushing into the left side of the front motor mount so that the shorter cavities are horiz

     Base Assembly - Front Passenger's Seat (Remove and Replace)

    Removal Remove the passenger's seat assembly (refer to procedure). Place the seat on a clean work surface. Remove the screws (x2) that secure the inner side cover to the seat (torque 1 Nm). Carefully release the inner side cover from the retaining bracket. Remove the
