Whew! Had me a little worried there. For a weekend fun toy, it'd be fantastic, but daily driver in Manhattan....ouch. I'm not sure if folks realize, but owning a vehicle and living in 'the city', you pay about $2500/rent for your apartment (known elsewhere in the world as a 'closet'), then another $500/mo. for a parking space. That's for the uncovered/outdoor ones. It's not much better in Queens, S.Island, the Bronx, or even Long Island. The roads are no treat either.
As far as snow tires, here's a suggestion:
1. Remove massive meats from truck day after first snowflake touches the ground.
2. Install standard Ram rim/tire setup with good all-season or M+S radials (check the spare for correct numbers). I'd check TireRack.com to see what they have available.
3. Get a tow rope and winter survival kit (flares, peanut butter, cell phone battery backup, blankets, etc).
4. Put two of the summer tires/rims in the bed for added traction.
5. Drive much more conservatively in snowy/icy/crappy weather. Dead guys don't get to drive nice badass trucks (they get to ride in a Cadillac one last time).
6. At the sight of first girl in a tank top, remove snow tires/rims and put the "good stuff" back on.
Yes- it's a little pricey (check FleaBay and junkyards for rims. Re-paint as desired).
Yes- they look like poo compared to the shiny 22s.
But...at least you'll be able to drive considerably safer.
I'm a couple of months out from buying mine, but if I still lived in Colorado, and this was my daily driver, that'd be my plan.
