When we moved up to Wyoming from AZ, we brought up a 2wd Suburban. It now has 200k on it, and I need two more years out of it. This spring, I threw on Capitol All Terrains, Chinese made tires in an LT245/75R16 LRE. For winter however, I am now putting on my 2nd set of General Altimax Arctics in the stock size of 265/70R16. I have them studded, and they are absolutely the best winter tire I have ever ran. The other winter tire I ran was a Mastercraft Courser MSR. I had them studded also, but the Generals were far superior.
