I'm wondering if anyone has purchased these chains ?
How are they working?
Do they hold up?
The thinness makes me think they might snap. Its not too bad for the price on two wheels. I assume the rears.
Model 3 Snow Chain - 20" Performance
The company that manufactures these chains is extremely reputable, and the chains are very reliable given how much they're used in eastern Europe. That's not Model 3 specific, but based on the fact that this company is just extremely popular and well reviewed.
The thinness of these units is due to the minimal clearance between the 20" wheels and the suspension components. If you attempt to use a more traditional chain, the center spans will catch on your suspension and will very likely strike the body panels at the lower side of your wheel well. These units fit more snugly to the tire itself.
Given you're in the bay area, I'm guessing you're planning for something like driving up to Tahoe? Don't do that on the stock 20" wheels, even with chains. I absolutely can not stress that fact enough. I ordered snow tires and wheels, the wheels were delayed, and I ended up caught in a storm. The summer tires are absolutely unusable in those conditions. Even a light dusting of snow makes them totally undriveable. If you're planning to make winter trips up to the mountains, you'd probably be better off going with a 19" wheel and decent all weather tire. I normally wouldn't ever tell anybody to go all weather or all season, but given how big the temperature and condition difference is in such a short distance, driving on snow tires would just be pointless.
Snow chains are really only best for when you've got winter rated tires already, and you need to get a bit more traction on hard packed snow. Otherwise they offer nothing at all. You should also expect your maximum speed with chains on to be 20MPH or less. Driving any faster can (will) cause damage to your car as well as the chains.
