Why this is a Tesla question and not just a snow question

The reason to write this one is that the usual advice about snow chains does not fit a Tesla very well, and a lot of owners find that out at the bottom of a mountain pass with a “chains required” sign in front of them. On most cars you buy whatever chains fit your tire size and put them on the drive wheels. On a Tesla, the owner’s manual names the exact chains you are allowed to use, tells you which wheels they go on, and tells you what happens to the warranty if you use something else. That is a narrower set of choices than most people expect, and it is worth knowing before the storm, not during it.

I’ll say where I’m coming from so you can weigh it. Our three cars, a 2021 Model 3 and two Model Ys, all run all-season tires year-round, and none of them has a winter set. That is a central Virginia decision, where snow is a few days a year and not a season. I have never used chains or socks on any car. We don’t get heavy snow here, and the times we have had snow, the Tesla handled it well. So this is not an article about my winters in chains. It is an article about what Tesla’s own documents allow, what the chain-law signs in the mountain states require, and which products fit inside both. Every Tesla claim below is quoted from the current Model Y and Model 3 owner’s manuals or Tesla’s support pages, read the week this was written. For the tire side of the decision, rotation, pressure and whether you should buy a winter set, I covered that in the tire care guide and I won’t repeat it here.

What Tesla allows

The Model Y manual opens its tire chain section this way: “Tesla has tested and approved the following tire chains (also called snow 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.” The Model 3 manual uses the same words. Then each manual gives a short table, by wheel size, of the chains Tesla approved. Here they are, combined, exactly as the two manuals list them on the day I read them.

Two things to notice. First, every approved chain is a König, and every one of them is built to keep its metal off the wheel face and inside a tight clearance. That is not an accident. Tesla’s chains are chosen for the tight clearance between the tire and the body, and the manual is blunt about what a wrong chain does: “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.” Second, the older 2020 to 2024 Model Y manual lists only the 19″/20″ and 21″ rows, so the 18″ row and the six-seat row are for the newer cars. The manual itself says to “Check your vehicle’s Owner’s Manual on the touchscreen for updated information on tire chains,” and I’d do exactly that before ordering, because the table on your screen is the one that applies to your car.

The rest of the rules are the same in both manuals and they are short enough to memorize. Rear tires only, and separately, “Do not use snow chains on the front tires.” Take the aero wheel covers off first, because “Failure to do so can cause damage not covered by the warranty.” Do not put chains on summer tires. Do not let air out of the tires to get the chains on, because when you reinflate them the chains can fit too tight and damage the tire. Drive slowly, “Do not exceed 30 mph (48 km/h),” inspect the chains for loose fittings and damaged links before each use, avoid loading the car heavily because a heavy load closes up the clearance between the tire and the body, and take them off as soon as the road allows. If you hear the chains touching anything, the manual’s instruction is to “stop and investigate immediately.” That last line is the one I’d underline. A chain touching a brake line is exactly the damage the warranty sentence is about.

Winter tires first, then everything else

Before the chain shopping, the honest order of operations. Tesla’s own cold-weather page puts it in one line: “Use winter tires to increase traction in snowy or icy conditions.” The manual’s tire section adds that all-season tires “may not provide the same level of traction as winter tires in snowy or icy conditions,” and that winter tires go on as “a complete set of four tires at the same time,” all the same diameter, brand, construction and tread pattern. Chains are the thing you put on for a few miles of the worst road. Winter tires are what you drive on for four months. If you live somewhere the snow stays on the ground, the tires are the purchase and the chains are the backup, and I’d rather you read that here than from a chain listing.

Now the part where I don’t follow my own advice, and why. All three of our cars are on all-seasons, and they stay on them. The blue 2023 Model Y is on Michelin Pilot Sport All Season tires, the red 2024 Model Y is still on the Continentals it came with. In central Virginia that works for us. What I do change in winter is the charge, not the tires: I normally charge to 80 percent, and in a really cold stretch I charge to 90 before my regular two-and-a-half-hour trip because I lose roughly 10 to 15 percent of my range in the cold. That is the honest version of “winter prep” at my house. If your winters look like Denver’s or Buffalo’s, copy the tire advice and not my tire choice. The winter accessories roundup covers the rest of the outside-the-car list, snow covers, brooms and wiper blades, and none of that is repeated here.

One more thing the tire question decides for you. AWD in a Tesla means a front motor and a rear motor, and it is very good at getting you moving. It does nothing for stopping or turning, because those are the tires’ job, and four all-seasons on ice stop the same whether one motor or two got you up to speed. Colorado’s traction law makes the same point in legal language: an AWD car satisfies the law only “with tires designated as mud and snow” or winter tires “and 3/16-inch tread depth.” AWD by itself is not on the list. I bring that up because “I have AWD” is the most common reason people give for skipping both the tires and the chains, and neither the physics nor the law agrees with them.

The Tesla-approved chains, by wheel

Tesla sells the approved chains in its own shop and through Service Centers, and if you can get them there, that is the simplest way to be sure you have the right part. When I checked the shop, the Model Y 19″/20″, Model Y 21″ and Model 3 18″ sets were all out of stock. The same König chains are sold on Amazon, and that is what I’ve linked below, with one warning that applies to all five: these are size-specific parts, and several of the Amazon listings are one size of a family, so when you land on the page, check that the size in the title matches the one in the table above and that your rear tire size is in the listing’s compatibility list. Your tire size is printed on the sidewall, something like 255/45R19. Read it off the actual tire, not from memory, because tire sizes change with wheel option and model year. The current Model Y manual, for example, lists 235/55R18 on the 18″ wheel, 255/45R19 on the 19″, 255/40R20 on the 20″ and 275/35R21 on the rear of the 21″ Performance car; the Model 3 manual lists 235/45R18, 235/40R19 and 275/30R20 on the Performance rear.

Two notes on the XG-12. First, the listing says it is built for SUVs and vans, which is the class the Model Y falls in. Second, it is not the cheapest chain on Amazon by a long way, and the search results around it are full of “universal” and “auto-tightening” chains at a third of the price. Those are the ones the manual’s warranty sentence is about. A universal chain has to fit a hundred tire sizes, which means it fits none of them closely, and the slack is what reaches the brake lines. If the price is the problem, the socks in the next section are the cheaper answer that still respects the clearance, not a bargain chain.

If you own a Model 3, notice what the two CG-9 sizes have in common with the Model Y’s XG-12 and what they don’t. Same brand, same self-tensioning idea, same rear-wheels-only rule. The difference is the clearance figure. Tesla did not pick the CG-9 for the Model 3 because it grips better; it picked it because it is the chain that fits in the space. That is also why you cannot borrow a friend’s Model Y chains for your Model 3 or the other way around, even though both cars are Teslas and both chains are Königs. Tire sizes and wheel-well room differ, and the manual’s warranty sentence about “other sized tires” is written for exactly that swap.

The one wheel I could not find a chain for is the Model Y 18″. The current manual lists “König CG-9 size 105″ for it. On the day I wrote this, the 105 was not on Amazon, only the neighboring sizes were, and it was not in Tesla’s shop search results either. If you have the 18” wheel, the manual’s own instruction applies: the approved chains “can be purchased from Tesla,” so call a Service Center and ask for the 105 by name, and do not settle for a CG-9 in a different size because the number looks close. The 18″ Model Y tire is a 235/55R18, a taller sidewall than anything else in this article, and the chain size is not interchangeable. For everything else that fits the Model Y, the Model Y accessories hub is the long list; if you have a 2025 or newer car, the Juniper accessories guide sorts out what changed.

Snow socks: the option Tesla’s manual doesn’t mention

A snow sock is a fabric cover that stretches over the tire. The textile is there to grip packed snow and ice where the rubber alone can’t, and there is no metal anywhere in it, so the two things Tesla’s manual warns about, the chain hitting the body and the chain grabbing a brake line, cannot happen. They are lighter than chains, they pack flat, and they go on in a couple of minutes without lying in the slush. They are fabric, so treat them as a consumable, take them off when the road is clear, and respect the maker’s own 30 mph limit, which happens to be the same number Tesla gives for chains. Here is the straight version of where they stand with Tesla: nowhere. The manual’s approved list is chains only and does not mention textile devices at all, and the warranty language is about “non-recommended tire chains.” A sock is not a chain, so I can’t tell you it is covered and I can’t tell you it isn’t. What I can tell you is what the states say, and that part is clear.

Colorado’s traction law page lists the approved alternative traction devices by name, and AutoSock is on it. When the state’s passenger vehicle chain law is in effect, “every vehicle must have chains or an approved alternative traction device,” and a sock on the list satisfies that. California’s Caltrans defines its R-2 level as “Chains or traction devices are required on all vehicles except four-wheel/all-wheel drive vehicles with snow-tread tires on all four wheels,” and adds that AWD cars “must carry traction devices in chain control areas” even when they are not required to put them on. Read that twice if you drive an AWD Tesla on all-seasons into the Sierra: at R-2 you need traction devices on the rear wheels, and even with snow tires you have to be carrying them. A sock in the trunk is the lightest way to be legal. Virginia, for what it’s worth, simply permits chains “when required for safety because of snow, ice, or other conditions tending to cause a vehicle to slide or skid,” and that one sentence is the whole rule here.

How I’d choose between a chain and a sock, if it were my car. If you live in chain-law country and use them several times a winter, buy the König chain from Tesla’s table, because it is the thing Tesla stands behind and it will outlast a sock many times over. If you need something in the trunk for the one or two days a year a sign says so, buy the sock: it meets the law, it goes on fast, and it cannot damage the car. What I would not do in either case is buy a universal chain because it was cheap. The manual’s list is short for a reason, and the reason is how little room there is between the tire and the brake line.

Getting unstuck is a different problem than driving

Most winter trouble in a Tesla is not a mountain pass. It is a snowbank at the end of the driveway, an unplowed parking space, or a shoulder you slid onto. Chains are the wrong tool for that: you are not going to lie in the snow to mount them for ten feet of movement. The car has two things in its own software for it, and the manual describes both. Under Controls, Dynamics, the traction control has a “Slippery Surface” setting that “distributes traction evenly across all tires to provide more traction and stability during slippery conditions, such as rain, snow, or ice.” The Model Y also has “Off-Road Assist,” which, “in addition to allowing the wheels to spin,” balances torque between the front and rear motors and gives “more gradual torque, which is useful for crawling at low speeds.” That is the one for rocking out of a rut. The manual warns that “Automatic Emergency Braking and Lane Departure Avoidance do not operate when Off-Road Assist is turned on,” so turn it back off once you are moving.

When the software isn’t enough, the fix is grip under the drive wheels and a way to move the snow. I covered both in the winter emergency kit article, and the two items below are the same two, because they are the right two. A traction board goes under the rear tires and gives the tread something to climb; a folding shovel clears the snow that has packed under the car. Neither one needs to fit a Tesla specifically, which is a relief after the chain section.

The cold-battery behavior that changes how the car feels on ice

One thing new Tesla owners find out on the first icy morning: the car does not drive the way it did the night before. Tesla’s Cold Weather Best Practices page explains it. “Regenerative braking can be limited if the Battery is too cold,” and the touchscreen shows “a blue snowflake icon” when part of the battery’s energy is unavailable, with “Regenerative braking, acceleration, and charging rates” all possibly limited until the pack warms. In practice that means you lift off the accelerator and the car coasts instead of slowing, and if you have been driving a Tesla for a while you have trained yourself to expect the slowing. On dry pavement that is a surprise. On ice it means you are reaching for the brake pedal later than you meant to. Tesla’s fix is to precondition. The page says “Tesla recommends activating climate settings at least 30-45 minutes before departure,” and a scheduled departure time in the app does it automatically. A warm pack gives you normal regen, normal acceleration, and a windshield that is already clear.

Two smaller items from the same page. Tire pressure: “The tires will lose one PSI for every 10° F (6° C) drop in outside temperature,” and low tires are worse on snow, not better, so top them up when the first cold snap hits and again when the TPMS light comes on. Range: the cold takes a real bite, which is the subject of the winter range loss article, and it is why I charge to 90 before a long cold trip. None of that is a traction device, but all of it changes how the car behaves on the days you’d be thinking about chains, and the preconditioning habit in particular costs nothing.

Chains, socks and boards compared

Frequently Asked Questions

Can I put snow chains on the front wheels of a Tesla for better steering?

No. Both manuals say “Tire chains should only be installed on the rear tires” and, in a separate caution, “Do not use snow chains on the front tires.” The reason is clearance: the front wheels steer, and a chain on a turning wheel sweeps through space the rear wheel never uses. Tesla’s approved chains were tested on the rear only. This is true on the AWD cars as well as the rear-drive ones; having a front motor does not change where the chains go.

Will using non-approved chains void my Tesla warranty?

Not the whole warranty, but the damage they cause is on you. The manual’s exact words: “Damage caused by using non-recommended tire chains, or incorrectly installing tire chains, is not covered by the warranty.” The same section names what that damage tends to be, “the suspension, body, wheels, and/or brake lines.” So a cheap chain that chews a brake line is a repair you pay for, and a correctly installed König that somehow damages something is a warranty conversation. That gap is the whole argument for buying from the list.

Are snow socks legal where chains are required?

In the two states with the most-used chain laws, yes for the products on their lists. Colorado’s traction law page names AutoSock among the approved alternative traction devices, and its chain law requires “chains or an approved alternative traction device.” California’s R-2 and R-3 levels call for “chains or traction devices.” Other states vary and some mountain roads have their own rules, so check the state DOT page for where you are going, not a blog post, and carry the device the sign will ask for. Tesla’s manual does not address socks either way.

Do I need chains at all if my Tesla is AWD?

Under Colorado’s law, an AWD car is exempt only if its tires are rated mud-and-snow or winter with 3/16-inch of tread. Under California’s R-2, an AWD car with snow tires on all four wheels can skip putting chains on but “must carry traction devices in chain control areas.” At R-3 everyone chains up. AWD on all-season tires with no chains in the trunk meets neither state’s rule when the law is in effect. More to the point, AWD helps you accelerate and does nothing for stopping, which is what puts cars in ditches.
