The tire size and wheel size for Your 2018 GMC Acadia is going to depend on what trim level You have. The SL and SLE models are going to use size 245/65R17 tires and have wheels that measure 17 inches in diameter and 7.5 inches in width. The All Terrain and SLT models are going to come equipped with size 235/65R18 tires and will have wheels that measure 18 inches in diameter and 7.5 inches in width. The top of the line trim is the Denali edition and it will use size 235/55R20 tires and come with wheels that are 20 inches in diameter and 8 inches in width.
