"Winterizing" my Yaris
I've got a 5spd Toyota Yaris (front wheel drive sedan FWIW). Live in the prairie southwest where there's not much snow, but am planning on taking it up to Colorado on a couple of trips this winter. Just looking to be able to climb the front range (I-70) during a blizzard or snowstorm, if necessary. Would like to avoid chains unless I hear from you all that THAT'S THE WAY TO GO. Coloradans, what's the rules on I-70 about chains/snow tires/4WD in snowy conditions? Do they check closely?
So other than the boarding trips, pretty much drive on dry/wet asphalt and concrete. Snow tires or all seasons? Should I get four, or just for the drive wheels? If snow tires, how quickly do they wear out on regular road conditions, should I change to my original tires as soon as I get back home?
Due to the rising cost of ammo, do not expect a warning shot! Sorry for the inconvenience.
