    Has anybody tried The Thule Easy Fit CU-9 snow chains (on 19 inch tires)? Any problems? They seem better than the Tesla supported Trak Sport.

    I purchased a set of these but haven't had the opportunity to try them. They look easy enough to install/remove and my brother (a long haul trucker) swears by them.

    With a RWD vehicle should they only go on the rear wheels or on all 4?

    Definately should only go on the rear wheels, regardless of 2 or 4 wheel drive. Thule has sold the snow chain division to Konig (also an Italian company). König Easy-fit CU-9 - König
    My worry with them is the 9mm links vs the 3mm links on the Trak Sport. It is still low profile so I think they should be fine, but I want to see if anyone else has used them first.

    Tire chains recommends all four. I'm not an expert but since the AutoSock is cloth, I see no harm in placing them on front & rear.

    Seems to me the ability to move forward is only useful when you have the ability to steer. ;)

    Tesla recommends the rear only on their Trak Sport page.

    You are absolutely correct that you would normally put snow chains on all four tires of a 4-wheel drive vehicle. Normally, though, 4-wheel drive vehicles tend to have more clearance between the tire and wheel well than the model S. I would guess that is why Tesla recommends only installing chains on the rear wheels and only on the 19" tires.

    From Tesla: "Chains should only be installed on the rear wheels of the Model S and only on 19" tires."

    Anybody know about the reports of suspension abrasion from Z-chains? I don't know whether the reports are for 19" or 21" wheels, or RWD vs. AWD cars (they didn't say)...I have a set (RWD S85) but am hesitant to use them until I can validate or dismiss the suspension issues...

    19" RWD abraded with Z chains. Trak's eliminate this issue and work well.

    Anyone use the "zip tie" style chains you can find on eBay? They are super cheap, and fit tires width 295mm. I'm thinking of just keeping a baggie of 10 zip ties in my trunk for the R2 days.

    For R2, if you have M+S tires (all-season) and AWD, you don't need to install the chains, but only have them in your trunk.

    I'm scared actually using any of these chains will scuff the rim or cause worse damage. There really isn't a great solution.

    Dang looks like I'm wrong I have Michelin Pilot Sport 3's which are max-performance summer. Guess I will need chains installed for R2 conditions.

    I just spoke to tesla service and they said that the Z-chains are perfectly fine - when installed correctly, and that they tested them for many miles before offering them. They switched because the newer chains are easier to install.
    The install procedure requires you to install, drive the car a few feet, and then stop and re-tighten the chains. And the chains are only to be used on 19" wheels.
    I don't know what to say about the reports of damage...broken chains? not tight enough?
    SweetP - can you elaborate on your experience with them?
