Re: 245/70r16 for 2011 wk2?
Aside from probably not fitting over the brakes, they are also almost a whole inch smaller in OD - I don't think that'd be a very good look personally. If you are looking for a decent winter set, check out wrangler take offs. I got a set of 5 255/70-18 for $300 on craigslist a while back. They are 32.1" OD, ~1.5" bigger in OD, but they fit without issue and even fit in the spare well with the cubbies out.
