I'd rather be in a 4 wheel drive rather than a 2 WD in wet and slippery weather. It's the ice, not the snow, that I'd worry about. Don't think that because you're in a 4WD that you don't need some type of traction device.
***** ADVISE******
Check your tire size then your owner's manual. You'd probably be surprised to learn that you can't use standard class S (Class S specification will mean that nothing will protrude over 1/2" if attached properly) tire chains and/or traction cables.
From about '88 or so to the present, some vehicles don't have the clearance between its strut assembly and the inner top/sidewall of the tire.
Toyota/Lexus owners manual will state (about 90% of its vehicles) that you can use Class S chains EXCEPT radial CABLE and V-bar reinforced chains.
The other 10% can't even use Class S chains. You'd have to get a chain with less than 3/8" width links (good luck finding those). Toyota has found that even though Class S traction cables are thinner than comparable chains, the cables tend to have it's ends stick out a bit more plus you can't use chain tightners on the cables (only one design I know of uses tightners with cables - Laclede Sure Grip Z type cables (Going by memory here, might be from Peerless.) Some BMW dealers sell those as their 'approved' traction device for about $90-125.
Honda/Acura, on the other hand will recommend Class S cables only on most of their vehicles.
Some Caravans (Voyagers, Town and Countrys), Saturns, Intrepids, Saabs, MBZs, BMWs, etc (just to name but a handful) can't use any type of cable/chain traction devise.
Gonna be stuck with the $300.- 400. Spikes Spiders.
If you have a minimum of 1" clearance between your strut and shield assembly (and/or your brake caliper for that matter) and your wheel/tire, you should be able to get away with a Class S chain or cable. I prefer the Laclede Alpine chains. Hardened steel thinner links. Better traction. Can be used on ABS systems. Easier to install over conventional cables or chains. Comes with the tightner attached. About $60.-80. for a set of two.
No matter what you decide to get, test fit them BEFORE you actually need them. Nothing will bum you out more because you had to go back because your traction device didn't fit.
Again, check your owner's manual on possible limitations. You might just get surprised.
