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 Y if a tire is damaged,
excessively worn, or inflated to an incorrect pressure.
Check tires regularly for wear, and ensure there are no
cuts, bulges or exposure of the ply/cord structure. In
addition, pay attention for wear on the tire's inner
shoulder.
Tire Wear
Adequate tread depth is important for proper tire
performance. Tires with a tread depth less than
3 mm are
more likely to hydroplane in wet conditions and should not be
used. Tires with a tread depth less than 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
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.
To improve vehicle handling characteristics and minimize
hydroplaning in wet conditions, put tires with the most tread
on the rear of the car.
Tire Rotation, Balance, and Wheel Alignment
Tesla recommends rotating the tires every 10,000 km or if
tread depth difference is 1.5 mm or greater, whichever comes
first.
Tire rotation is an essential part of tire maintenance. It helps
maintain an even treadwear pattern which enhances the tire's
overall wear quality, decreases road noise and maximizes tire
life.
Vehicles with staggered wheels and non-directional tires can
be rotated side-to-side (left-to-right) but not front-to-back
as the front and rear tire size is different. Left-to-right
rotation can increase tread life by changing the direction of
rotation for each tire and balancing shoulder wear.
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 wheel alignment. If the tires
need to be serviced, such as rotated or replaced, reset the
tire configuration (see Tire Configuration on page 176) to
improve your driving experience.
Punctured Tires
A puncture eventually causes the tire to lose pressure, which
is why it is important to check tire pressures frequently.
Permanently repair or replace punctured or damaged tires as
soon as possible.
Your tubeless tires may not leak when penetrated, provided
the object remains in the tire. If, however, you feel a sudden
vibration or ride disturbance while driving, or you suspect a
tire is damaged, immediately reduce your speed. Drive
slowly, while avoiding heavy braking or sharp steering and,
when safe to do so, stop the vehicle. Arrange to have
Model
Y transported to a Tesla Service Center, or to a nearby tire
repair center.
NOTE: In some cases, you can temporarily repair small tire
punctures (under 6 mm) using an optional tire repair kit
available from Tesla. This allows you to slowly drive
Model Y
to Tesla or to a nearby tire repair facility.
WARNING: Do not drive with a punctured tire that has
not been repaired, even if the puncture has not caused
the tire to deflate. A punctured tire can deflate
suddenly at any time.
Flat Spots
If Model Y is stationary for a long period, tires can form flat
spots. When Model Y is driven, these flat spots cause a
vibration which gradually disappears as the tires warm up and
regain their original shape.
Improving Tire Mileage
To improve the mileage you get from your tires, maintain tires
at the recommended tire pressures, observe speed limits and
advisory speeds, and avoid:
•
Pulling away quickly, or hard acceleration.
•
Fast turns and heavy braking.
•
Potholes and objects in the road.
•
Hitting curbs when parking.
•
Contaminating tires with fluids that can cause damage.
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 if required, even if tread depth is above
the minimum.
