Finding the right upgrade means choosing from trusted brands like Heritage Wheel, Petrol, American Racing, and Asanti Black, all available in sizes that suit your Terrain.

2020 GMC Terrain SL Wheel Fitment Guide — What Works & What to Avoid
Your 2020 GMC Terrain SL uses a 5x115 bolt pattern. Factory wheels are 17x6.5 with a 35mm offset. You can step up to 17, 18, or 19-inch diameters, with widths ranging from 6.5 to 8.5 inches depending on diameter. Since this vehicle runs the same setup front and rear, any compatible size works as a four-wheel set.
The Terrain only accepts 5x115 bolts—no other pattern fits. Your wheels must hub-centric to our 70.3mm bore; if a wheel's center bore exceeds that diameter, use hub-centric rings to ensure proper centering. Choosing widths or offsets significantly beyond stock can cause rubbing against fenders and suspension components, so aggressive fitments demand careful verification.
Every wheel we offer for your Terrain is guaranteed to bolt on and ships free across the lower 48 states. Browse Heritage Wheel, Petrol, American Racing, and Asanti Black among the eight quality brands we stock that fit your vehicle.
