Still a bit confused about Snow Chain compatibility.
From current Model S Manual:
“Tire Size Recommended Chain
19" KONIG K-SUMMIT
Do not use tire chains on 21" tires.”
Yet, the description of the König K-Summit K45 snow chains for 19” tires in the Tesla online store states:
Note: Compatible with Model S vehicles produced in 2012-2020.
So , either the manual contains legacy info or the online store wasn’t updated for 2021
???

2012-2020 | Model S Snow Chains
Tesla Online Store Description:
2012-2020 | Model S Snow Chains
The König K-Summit K45 snow chain provides excellent traction and durability in snowy conditions. With no complex attachments, the newly upgraded design simply requires one fixing point on the outer side of the drive wheels. The fitting system has been pre-configured for Model S 19” Wheels…
Note: Compatible with Model S vehicles produced in 2012-2020. The set includes one pair of chains for two wheels. Chains should only be installed on the rear wheels of the Model S 19" tires. The use of non-recommended tire chains has been shown to cause suspension and other vehicle damage. Do not exceed 30 mph (50 kph) when driving with snow chains installed.
From current Model S Manual”:
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" KONIG K-SUMMIT
Do not use tire chains on 21" tires.
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.
• Set air suspension to Medium and turn off the Default Ride Height to Low setting.
• Avoid heavily loading Model S (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 30 mph (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.
