I'm hoping to take a solo road trip from Vancouver, BC to Mesa, Arizona via Vegas in the next week. My car has all-season tires. Are there many mountain passes along the route? Will chains be sufficient? Or will I need to purchase winter tires (which I'm trying to avoid).

I will have my 13 year old daughter with me on the way back, and we will drive through California on our return.

Any suggestions of things to check out on either trip would also be appreciated.

Thanks in advance!
