I'm not sure I agree with this.
A smaller footprint should work better on ice as well. Less area of potential "slip" for each pound of force. Tires aren't shaped like ice skates, but I'd point out that, while skates slip easily forward and backward, they grab pretty well from side to side.
Also I've repaired/replaced a number of tires in my life and I've never seen on punctured by ice.
If its working for you though, who am I to say. Cheers.
I actually think you made his point. Ice skates in the direction of the skate blade slide easily, but grip well in the wider cross direction.
I am not sure that an analogy between a steel blade meant to cut into ice versus a rubber tire means a lot however. I guess a skinnier tire might tend to cut into the ice and give you better steering qualities, but when you hit the brakes, be prepared to slide like, well, a skater on ice. Surprised no one has discussed studded tires yet, or did I miss that discussion?
Outside of nails, screws, and other pieces of metal that have assaulted my tires, the only other time I have replaced a tire involved my few weeks old Wrangler. I wish I could tell some great story of traversing the Rubicon trail or some other great feat, but instead I was traveling the urban jungle we call the DFW Metroplex and a large chunk of concrete had broken off, creating a crater, but leaving the chink sitting up on the small two lane road. With no where to steer around it, the tire hit it and it sliced the side wall. The thread about TPMS pressure variations had a post about it being nice to get a warning before a tire went flat made me chuckle. This is the only time (KNOCK on wood) I have ever had a tire failure on the road personally, but the time between the hitting the concrete, having the TPMS alert, and sitting on a total flat tire was measurable in seconds that could be counted on one hand. Of course, then there was the issue that no one had the tires in stock, in fact most told me I couldn't read the tire size on my tires and I was an idiot. Took several days to get a replacement tire ordered and installed: This is why I always want a full size spare.
Back to the original premise: As others have said, this is a truck. It is going to behave differently than your old FWD vehicle. For those of us who learned to drive with rear wheel drive vehicles, it isn't quite as hard to adjust to a truck's behaviors. If this is your first RWD vehicle, especially a truck, be prepared to have to make some adjustments to your driving style.
