This is a very interesting thread as I am also looking for tires with some winter capabilities (Tahoe) for my 2001 4Runner.
What is the consensus on LT vs P for a stock 3rd Gen 4runner (stock size tire)? this seems like a good deal today - $598 for 4 AT3 LT:

I'd jump on that deal. Though if you really think you want them primarily as a winter/snow tire. I might consider something more winter biased.
I grabbed a set of At3s a few years when they first came out for my van for about $100 a tire. At the time they were no name and I took the chance primarily because of the silica based rubber and the knowledge that Nokian had been contracting cooper to make their Vatiiva line of tires awhile back. I bought P-metric 235 70-16s for the van. I
thought i would have preferred an LT tire but the load rating was more than sufficient for the van so I figured at $100/tire, why not. They've been on the van now for over 15k and I literally feel, for the price paid, like I stole the tires. Very happy with them, more mushy than the D-rated Nokian commercial van snows they replaced (which I now run on my Volvo) but the trade off for that was a really, really nice riding tire.
I really only use the van for loaded weekend warrior trips, hammered them really hard, mostly in S. Utah, and had zero issues on a fairly heavy vehicle. It is an AWD van so I'm not rock crawling but I am taking it places, and over rocky roads that folks feel I have no place taking an Astro.
When I bought my Montero I elected to put C Ply LT-rated Hankook ATMs on it. In all honesty, again...I don't rock crawl, I kind of wish I was running p-metrics on that truck too. Factory spec is a p-metric tire and I'm not real keen on the ride quality of the LT tire. I know lots of people will howl but I think for all but the real difficult 4x4 trails, vs, overlanding a P tire is sufficient (provided it handles your load requirements!!). One thing people worry about is sidewall protection when airing down, that said, I really don't bother airing down my P tires as the ride is sufficiently compliant. You'll notice a theme in my comments, I trend toward the lighter duty side of things. I think lighter duty works well and often times going heavy duty involves a downward spiral of requiring more and more HD components JUST to handle the added weight of said components. I don't think all that many folks here agree with my philosophy.
