I have X-ice on a Prius and they work remarkably well - not sure if they come in many LT sizes though. For my previous Tacoma I had Blizzacks, that do come in LT sizes and higher load ratings. At least for slick rock stuff (Utah) the Blizzacks actually worked better than the BFGs, probably due to their super soft and sticky rubber. This probably wasn't good for their longevity, but I still got 7 winters out of them and sold them with tread left when I sold the truck. I never really tried them in mud, but my guess is that they would not have worked so well.
