I am leaning toward the Yokohama Geolandar I/T G072 for Winter. On 1010tires.com, customers have given it a 4.3 of 5 rating. I have the Yokohama Parada Spec-X tires on my 2011 Limited now and although they seem to have a fairly aggressive tread pattern, they are not a Winter tire. Looking to put the base model 17" steel wheels on the Limited. They should fit but the dealer wants to try one first to confirm. The 17" tires are much less expensive than the 20". Will also consider the BFGoodrich Winter Slalom KSI.
They do not seem to be available in the States.
