Tire Care and Maintenance
Using Tire Chains
Tesla has tested and approved the following tire chains
to increase traction in snowy conditions. Tire chains
should only be installed on the rear tires. The approved
tire chains can be purchased from Tesla.
Tire Size Recommended Chain
19"/20" KONIG XG-12 PRO SIZE 252
21" KONIG K-SUMMIT XXL K66
CAUTION: If your Model Y is equipped with aero
covers, you must remove them before installing
tire chains (see Removing and Installing Aero
Covers on page 173). Failure to do so can cause
damage not covered by the warranty.
When installing tire chains, follow the instructions and
warnings provided by the tire chain manufacturer. Mount
them evenly and as tight as possible.
When using tire chains:
• Inspect the tire chains for loose fittings and damaged
links before each use.
• Avoid heavily loading Model Y (heavy loads can
reduce the clearance between the tires and the
body).
• Do not drive the vehicle without the chains properly
installed.
• Drive slowly. Do not exceed 48 km/h.
• Remove the tire chains as soon as conditions allow.
NOTE: Tire chains are prohibited in some jurisdictions.
Check local laws before installing tire chains.
CAUTION: Using non-recommended tire chains, or
using tire chains on other sized tires can damage
the suspension, body, wheels, and/or brake lines.
Damage caused by using non-recommended tire
chains, or incorrectly installing tire chains, is not
covered by the warranty.
CAUTION: Do not use tire chains on the front tires.
CAUTION: Never deflate your tires to put on tire
chains. When re-inflated, the chains might fit too
tightly and cause tire damage.
CAUTION: Ensure that the tire chains cannot touch
suspension components or brake lines. If you hear
the chains making unusual noises that would
indicate contact with Model Y, stop and investigate
immediately.
