I am a new owner of a 2018 Q7 with Goodyear Eagle Sport Run Flats (285/45 R20) . I live in the north east but drive to Colorado for the winter into ski resort areas. Driving in mountain areas will be limited to ten mile commuting and shopping trips.

What recommendations do you have for using OEM tires vs. changing to “four-season” (not “all-season”) or dedicated snows? Former car had Nokian EnTyres that worked quite well. My concern (besides cost and inconvenience) is comfort of winter tires driving cross country on interstates. Thanks.
