Thanks for the response We will be driving a F250 crew cab disel with 4x4 and good tires Guess I'll buy some chains and take with me to be returned if not used
Nothing more dangerous than a flat land Texan driving on ice and snow!!!
Don't waste your money on chains if you have a vehicle like that!!! I've lived in Colorado for over 50 years, much of that in the mountains. I've only needed chains a handful of times, and those were with 2 wheel drive vehicles. I've never needed to chain up any of my 4x4s. And my driving has included some pretty heavy blizzards.
The main paved highways are usually well plowed. If it gets bad enough that chains are needed on a 4x4 they'll close the road. The worst you will likely see is snowpacked roads or a few inches of snow.
BTW, I skied for the first time of the season yesterday. I went to Loveland Basin, right at the Continental Divide west of Denver. The snow was great. It's been a great year so far, as Loveland has already received 229 inches. However, the roads were absolutely dry right up to the parking lot.
