The tire sizes that fit Your 2015 GMC Terrain are 225/65R17, 235/55R18, 235/60R17, 225/60R18, 235/55R19, and 245/45R20. In case You also wanted to know what the tire pressure is on Your vehicle, it happens to be 35 psiAcross all tire sizes. The rim sizes are pretty basic on the Terrain for this year. They are 7Jx17, 7Jx18, 7Jx19, and 8Jx20. Knowing what type of tires You have and how much pressure to add to them is very crucial to keep the life of Your tires. I recommend checking Your tires before going on a long road so that You avoid any accidents. An underinflated tire can overheat and bulge therefore causing a blowout on the road.
