Re: Winter tires
You live in the Denver area and you purchased a FWD vehicle....mistake...BIG mistake.
Tires might help, but in my opinion not enough to overcome the wintertime HAZARDS of FWD you will encounter in your area.
I would suggest you take yourself to LA and trade that FWD in for a F/awd. No real shortcoming to FWD in that climate and you might be lucky and find a F/awd on an LA dealer's lot that otherwise might not sell quickly.
Then add a manual switch to fully engage/power the rear drive coupling but only when you are driving on a KNOWN slippery surface. With the switch activated should conditions get really dire you will be able to use tire chains, effectively, on the rear without otherwise adding to teh wintertime driving HAZARDS via use of tire chains on the front.
My personal opinion is that summer use tires are so advantageous, more tread contact CSA, throughout the year, my approach is to use those year 'round and rely on tire chains otherwise. Rear chains first/initially, and only add the fronts in REALLY dire situations.
