We use the Subaru Outback for snow driving in the mountains with tire chains.

Would anyone have some information?

Copied from CalTrans page:
Chain Requirements:

R1: Chains, traction devices or snow tires are required on the drive axle of all vehicles except four wheel/ all wheel drive vehicles.
R2: Chains or traction devices are required on all vehicles except four wheel/ all wheel drive vehicles with snow-tread tires on all four wheels.
(NOTE: Four wheel/all wheel drive vehicles must carry traction devices in chain control areas.)This answers your question.
R3: Chains or traction devices are required on all vehicles, no exceptions.

Personally, I carry snow cables in my AWD JIC. I've never had to chain up AWD, but one never knows. If conditions are so bad that AWD vehicles need chains, you would probably turn around anyway.

Have fun at the Tahoe Ski Areas.

You will be glad you have AWD on 50 to South Lake Tahoe during a snow storm. If you are going to Kirkwood, there are TWO chain control places between the foothills and Kirkwood. Good luck, have fun, let us know how things go for you.
AWD vehicles are required to carry traction devices in chain control areas, per CalTrans.

I've driven with cables before. I think AWD and cables both help with getting my car moved, but only cables help with braking (a lot!)

You are absolutely right. AWD without traction devices are great for going forward and steering, but many inexperienced drivers find out quickly that without cables or chains, the stopping distance is greatly increased. I've driven this route, 50 & 80 to Tahoe, many times in the snow and there are always thoughtless people in AWD vehicles speeding and passing in the snow. They usually end up in the ditch facing the wrong way or worse.
Point being, not advised to go over 30 MPH in the snow no matter what.

How much clearance does my RX 450h AWD with 235/55-19 tires have around it? Do I need low-profile cables? I'm looking at these three products from SCC:

1. Z-575
   Z-575
   , no tightener required. I have a set of SZ435 cables from my dearly departed X5, but they don't fit my RX tires.
2. Super Z6, SZ429
   Super Z6, SZ429
   , low profile, for vehicles with limited clearance around tires
3. ZT729 Super Z
   ZT729 Super Z
   , looks a lot like Super Z-6, but $7 cheaper

Will any of these work? Also, page 281 of the manual says "Install tire chains on the front tires only. Do not install tire chains on the rear tires."

Does this change with an AWD vehicle?

Well, it looks like nobody loves me , but I ordered these ones, and they're "out for delivery" as we speak.

I'm driving up to Mammoth on Thursday, but there's no snow in the forecast this weekend. If I get surprised and have to use the chains, I'll let everyone know how it worked out.

Does anyone know if I can use Z-Chains on RX 400h with 18" tires? The dealership claims spider spikes are my only option since regular chains might interfere (or even cut) the brake lines. I'm not quite ready to invest $500 in the spikes and would love to find another option.

Finally a helpful post. Please let me know if you had to use the Z-Chains and how well they worked. I'm thinking about ordering some.

I've used Z-Chains on snow before, very effective. Putting them on takes practice if you've never done it before.

I have a pair of autosocks that I haven't field tested so I don't know how effective they are. What I like about them is if they break they won't cause a lot of damage to the car. They just got approved by CA DOT this year to be used in chain control areas (http://www.autosock.us/california-approval/)

RX400hSNOW

Thanks for the reply. I researched both quite a bit last night and some of the Z-Chain review say the product breaks easy and can damage the break line, which is what the dealership is telling me. I really like the AutoSock idea but supposedly they break and don't really work well when driving up/down hill so I'm not sure what to do.

Which type of chains does the dealership recommend you?
Chains do break, but I think the chance is pretty low unless you drive over 30 or on dry surface. Sounds like you have to do a lot of snow driving? My take is maybe just give autosock a try, if it works well enough for you, good! Otherwise if it breaks (still won't damage your car) or not work you can go back and research chains.

The dealership recommends snow spikes as the only option but I am not ready to invest $680 since I'll only be needing them for the weekends and we don't even get that much snow on the road. We ski at Mt. Hood in Oregon. Would you please field test them and let me know.

I finally watched their product video and ordered it. It looks like it should work well for what I need it for. Thank you!
