Dumb question: For driving around ski resort areas like Mammoth or Tahoe, I think the roads are generally plowed. So, I'm guessing an LX570 with K02 will be okay w/out chains. However, it weather is really foul and chains are required for all, on which wheels do I install chains? I'm reading on the web that for AWD, chains on all 4 wheels is recommended. But when I read the manual, on one page, it says install chains on the front wheels "... purchase a set of tire chains for the front tires" but then on a subsequent page it says to install on the rear wheels "Install tire chains on the rear tires."
So: 1) is it fair to assume that I won't need chains at all except under the most extreme weather conditions where roads will likely be closed and I should just stay indoors anyway - if 2wd w/ chains are okay, I should be okay w/o chains; 2) if I really do need chains, install on which wheels?
Here's a thread with a lot of discussion. I believe the only "approved" method regarding chains is on rear wheels only, and on factory-approved tire sizes. Deviating from that is a risk you must be aware of.

Tire Chains on a 200 Series?
