Going on a road trip south next week, so put the 3-season tires on the Yukon today.
Pretty pleased with the Yukon's tires overall. The 3-seasons are at 7/32" after 80,000kms. I'll probably run them this summer, then replace them. Plenty of tread left, but the rubber is starting to look a little old.
And the winters are wearing well, too. Still have 12/32" left after four winters and 25,000 kms.
