Model X uses different size tires on the front and rear and the tires
are directional, so the tires cannot be rotated.
Installing New Tires
The vehicle ride quality and handling are maximized when all 4 tires are
the same age, model, and tread depth. Tesla recommends replacing a tire
if any of the tread depths are 4/32 in. (3 mm) or less.
If only 2 new tires are installed, the new tires must be installed on
the rear of the vehicle. In wet conditions, the tires that have less
tread have less traction than the new tires. Reduced traction at the
front of the vehicle leads to understeer, which most drivers are better
able to react to than the oversteer that would result if the worn tires
were on the rear of the vehicle.
