tire suggestions for a winter conditions to summer conditions drive

[Alanda]

Hi!
We are driving from Calgary to Pacific coast Mexico.
We are planning to leave in December, so we will be hitting some winter conditions on Mountain passes and then into summer conditions. We will be heading back in April/May-ish so, kind of the same thing.
We want to get some tires that will do well for the passes, but also be okay in the hotter conditions (longevity). I've only had one quote from Kaltire so far and they suggested Michelin tires. I'm open to all suggestions. Safety is our first priority and we are planning to wait out any big storms we may come across. We are also getting chains.
Thanks in advance.
