The BFGs are quite expensive. That being said, when you look at pickup trucks around here, about 75% have them. Toyos are much less common. I'm not sure if they stand up to the abuse in marginal conditions, logging roads, etc. I could be wrong! And also for towing, I know their weight rating is available in C or E so they'll likely stand up to the load.
tire rack doesn't have them, so you can't use their tire comparison chart. The rest are here:
Consumer Survey Results By Category The BFG s #10 on the list and doesn't rate very good in wet, or hydroplaning resistance. On the other hand, it rates well in snow, deep snow, and treadwear. They don't ask how it does on rocky, rutted roads / offroad situations (such as you might encounter in Alaska)
