Tire Wear
Adequate tread depth is important for proper tire
performance. Tires with a tread depth less than
4/32”
(3 mm) are more likely to hydroplane in wet conditions
and should not be used. Tires with a tread depth less than
5/32” (4 mm) do not perform well in snow and
slush and should not be used when driving in winter conditions.
Model Y is originally fitted with tires that have wear
indicators molded into the tread pattern. When the
tread has been worn down to
4/32” (3 mm), the
indicators start to appear at the surface of the tread pattern, producing the
effect of a continuous band of
rubber across the width of the tire. For optimal performance and safety, Tesla recommends replacing tires before the wear indicators are visible.
Tire Rotation, Balance, and Wheel
Alignment
Tesla recommends rotating the tires every 6,250 miles
(10,000 km) or if tread depth difference is 2/32 in (1.5
mm) or greater, whichever comes first.
If Model Y comes with staggered wheels, tires cannot be rotated, as tires are asymmetrical and front tires are a
different size from rear tires.
Unbalanced wheels (sometimes noticeable as vibration through the
steering wheel) affect vehicle handling and
tire life. Even with regular use, wheels can get out of balance. Therefore, they should be balanced as required.
If tire wear is uneven (on one side of the tire only) or
becomes abnormally excessive, check the alignment of wheels.
NOTE: When replacing only two tires, install the new
tires on the rear if your vehicle
