Hi Johnny,
I am in upstate NY. Se we get everything from fresh snow on the roads to what is my biggest concern, wet slush, and berms created by our lackluster DOT. The wet slush gives you that directional stability you mentioned, especially when there is anything refreezing on the roads here. They use so much salt, it is a wonder anything is alive come spring alongside the roads. I think anyone here in my area can attest to that.
My previous experience had taught me that big wide tires weren't always great on the snow. In fact, you tend to see more SUVs off the road then FWD sedans when the weather gets bad around here. I am willing to dedicate a specific set of rims and tires just for winter, and considering I am new to the Titan trucks, I wanted to get a consensus on the idea.
As a side question, there is someone local selling rims off of a 2005 Titan. These appear to be a more basic steel rim. I've posted a pic
...think these would fit as well? Have you seen a rim like this? Very different from the stock ones on the truck currently.
