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 two labels attached to Model 3.
Both labels are located on the passenger side of the vehicle. The Product Plate can be seen when the rear passenger door is open. The Tire Information label can be seen when the front passenger door is open.

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.
The Product Plate provides the Maximum Allowable Total Mass. This is calculated as the weight of Model 3, all passengers, fluids, and cargo.

Model 3 supports the use of Tesla-approved roof racks using a Tesla mounting accessory. To install roof racks, you must use this accessory and you must use only roof rack systems that have been approved by Tesla (see Parts and Accessories). Failure to do so can cause significant damage.
