Average temp her in Myrtle Beach in January which is the coldest month is 40F. Had several days/mornings in low 20'sF. Temperature swings here are usually about 15F from early to mid/late morning. Surely I will be OK. The larger concern was going up north to visit family in December. Will have to take my GS350 AWD on that trip.Understanding how to handle those tires in challenging conditions might be a good idea.
Some good drivers are able to get by winter safely doing that alone.
