Thanks, main question I still have is where to buy the winter tires.
Best case driving from Houston Texas in Mid December to Steamboat Colorado the roads are dry no snow. If that is the case the all season tires seem good. Buy tires in Steamboat. If weather is snow bound of course best to be driving over the Eisenhower Tunnel & Rabbit Ears pass with winter tires. Not being able to know the exact road conditions and road temps question is where to buy the winter tires. If I buy winter tires in Texas road temps & road conditions could be above 50 F. Will that cause problems of tire deterioration chunking by driving at 75 MPH speed limit on I-25 north?

Thanks
