I have a 2017 RX 350 and are considering driving to Colorado this winter to go sking. Anyone that lives in the Colorado area, can you give me some feedback on how the car performs on I70?

 

It's more about what tires your vehicle has. I'll remind you of this, have tire chains with you. You don't want to get caught in the mountains without them. Chain law here applies to passenger vehicles too, including awd. If you have good tires and chains with you, you'll be fine.

 

Exactly what Coleroad said, tires are the key at this point.
