It is important to understand your vehicle's original tire sizes and pressures, and the TPMLM (Technically Permissible Maximum Label Mass) and TPMAM (Technically Permissible Maximum Mass on Axle). This information can be found on a label attached to Model S, and visible when the front door is open.
The arrow points to the Tire Information Label.
Tire Information Label
The Tire Information label provides:
- The maximum number of occupant seating positions.
- The size of the original tires.
- The cold inflation pressures for the original front and rear tires. These pressures are recommended to optimize ride and handling characteristics.
Never change this label, even if you use different tires in the future.
