No, the ones that I'm calling summer tires are all season tires. The ones that are on the van are winter tires...bit better for serious winter weather.
I figure the all season would work fine for the trip, even if we hit a bit of snow. Might be able to sell the snow tires. I might assign that to the boys...let them take commission. ;-)
Oh, OK, now I understand. Well, from Jen, it sounds like there's not a hugh snow problem in CO, so selling the winter tires is much more practical!
