Driving a Model Y in the winter feels like cheating—until the ice gets real. You've got that dual-motor grip, a low center of gravity, and enough torque to pull a small house. But physics is a stubborn jerk. When the mountain pass rangers put up the "Chains Required" sign, your AWD badge won't save you from a ticket or a ditch.
Most people think throwing a set of generic cables on a Tesla is fine. It isn't. Honestly, the clearance behind those tires is tighter than a pair of skinny jeans after Thanksgiving dinner. If you pick the wrong model y snow chains, you aren't just looking at a scratched rim. You're looking at severed brake lines, shredded wheel well liners, and a very expensive conversation with a service technician.
The Zero-Clearance Nightmare
Here is the deal: the Model Y has almost no space between the inner tire sidewall and the suspension’s upper control arm. If you stick a traditional, chunky link chain back there, it will smack into the hardware.
Tesla is super specific about this. They officially recommend the König XG-12 Pro 252 for 19-inch and 20-inch wheels. For the 21-inch Überturbine crowd, it’s the König K-Summit XXL K66. Notice a pattern? These aren't your grandpa’s rusty chains. They are low-profile or "external" systems designed to keep the metal bits away from your delicate sensors and air suspension components.
I’ve seen guys try to save $100 by buying "S-Class" compatible cables from a local auto shop. Sometimes it works. Often, the cable tensioner isn't quite right, the cable slaps, and suddenly the car’s computer is screaming about a traction control failure because a sensor wire just got snipped.

Why Rear Wheels Only?
It sounds counterintuitive. "I have All-Wheel Drive, shouldn't I put them on the front for steering?"
No. Never.
Tesla strictly forbids chains on the front tires of the Model Y. The clearance up front is even worse than the rear. If you put chains on the front, you risk hitting the steering knuckle or the wheel arch when you turn the wheel. Always install your model y snow chains on the rear tires only, regardless of whether you have the Long Range AWD or the Performance model.
Regenerative Braking: The Hidden Danger
This is the part that catches people off guard. When you lift off the accelerator in a Tesla, the car slows down aggressively to put energy back in the battery. On dry pavement, it’s great. On a sheet of ice with chains on? It can be a disaster.
If the regen kicks in too hard on a slick downhill, your rear wheels can lock up or slide before the computer can react. This is why seasoned Tesla winter drivers often switch their settings.
- Go to Controls > Dynamics.
- If your software version allows it, set Regenerative Braking to "Low."
- Turn on Chill Mode.
Basically, you want the car to behave as "dumb" as possible so you have manual control over the stopping power. Since late 2024, some software updates have improved how the car handles "Slip Start" with chains, but don't bet your bumper on it.
The "Socks" vs. Chains Debate
If you live somewhere like Seattle or Vancouver where you only see snow twice a year, you might consider "Snow Socks" (like AutoSock). They are basically high-traction fabric covers.
- Pros: They can't hurt your suspension. They are incredibly easy to slip on. They meet most legal requirements for "traction devices."
- Cons: They shred the second you hit dry asphalt.
If you're traversing a 4,000-foot mountain pass, socks might not cut it. They lack the "bite" into deep pack that a steel chain provides. For the serious stuff, you want the König setup.
Real-World Installation Tips (Don't Skip These)
First off, take those plastic aero covers off. If you leave your Gemini or Induction covers on while using chains, they will be ruined. Scratches, cracks, the whole bit.
Practice in your driveway. Seriously. Do it now, while it’s 50 degrees and sunny. Trying to figure out a König ratchet system while your fingers are numb and a blizzard is blowing sideways at a rest stop is a special kind of hell.
Keep your speed under 30 mph. I know the car is quiet and feels stable, but chains are mechanical devices held on by tension. At high speeds, centrifugal force makes them expand. An expanded chain is a chain that hits your wheel arch.
What to Do After the Pass
Once you hit clear pavement, get those model y snow chains off immediately. Driving on dry roads with chains is like taking a jackhammer to your tires and the road surface. It's loud, it's vibrating your $50,000 car to pieces, and it’s dangerous.
After your trip, spray the chains down with WD-40 or a similar rust inhibitor before putting them back in the bag. Road salt eats through cheap steel in weeks, and even the high-end König sets will get "crunchy" if they sit in a damp trunk all summer.
If you’re serious about winter safety, look into a dedicated set of 18 or 19-inch winter tires like the Michelin Pilot Alpin 5. Chains should be your last resort, your "get out of jail free" card, not your primary winter plan.
Pack a pair of waterproof gloves and a small headlamp in your sub-trunk. You'll thank me when you're kneeling in slush at 6 PM on a Sunday trying to find the tensioning lever. Check your tire pressure before you leave, too. Cold air drops PSI, and chains fit best on a properly inflated tire. Don't deflate your tires to "make the chains fit"—that’s an old-school trick that will just get you a "Low Tire Pressure" warning and a potential rim strike.
