The Firestone Destination St tires in the pictures are P255/50R19. They are available on the Firestone/Bridgestone's web site. These are a performance tire, and not really good in the snow. I had Bridgestone Dueler H/L Alenza Plus on my Nitro, and they performed flawlessly in the snow, and they are also available in this size. But, the Nitro was 4WD, and my Crossroad is FWD. My Nitro had 20s. I'm going to try the Khumos in the snow this winter and see how they perform. If I have any issues, I'll mount the Duelers.
BTW, when I purchased the Duelers for my Nitro, I did want the Destination Sts, but the tire salesman talked me into the Duelers because he told me that they were a much better tire.
The Destinations in the picture are 10.04" wide, compared to Khumos at 8.86" wide.
