Bridgestone Winter Duelers. Absolutely Amazing in all ice, snow, and other
winter garbage. I once drove into [or rather off-course!] a 24" fresh snow
spot and was able to self-extricate easily using the rear diif-lock [Syncro
Westy]. The BS tires are a tad less expensive than Hakkas. Adding weight, in
my opinion, is asking for trouble, the van is already weighted well. True
snow/winter tires are key. And use FOUR, not two, if you don't like
unintended spins!
