Detailed tire and wheel breakdown for the 2017 GMC Terrain
Tire geometry â 225/65R17
The 225/65R17 fitted to the 2017 GMC Terrain has a section width of 225mm and an aspect ratio of 65%, mounted on a 17-inch rim. That gives a sidewall height of 146.3mm (5.76") and an overall outside diameter of 724.3mm (28.52"). At highway speed this tire completes roughly 439 revolutions per kilometre, which is what your speedometer and odometer are calibrated against.
Plus-sizing window
If you want to upsize wheels on the 2017 GMC Terrain while keeping the speedometer accurate, target a 235/57R18 (plus-one). For a softer ride or winter setup, a 215/74R16 (minus-one) keeps the overall diameter within Âą3% of stock, which is the industry tolerance for ABS and stability control to stay calibrated.
Wheel fitment specs
The 2017 GMC Terrain uses a 5x120 bolt pattern with a 66.9mm hub bore. Safe rim width range for the OEM tire is 6.5J â 7.5J, and offsets in the ET41 â ET51 window will clear suspension and fender without rubbing on most setups.
Tire pressure guidance
Manufacturer-recommended cold tire pressure for the 2017 GMC Terrain is printed on the driver-side door jamb sticker â always defer to that value, not to the maximum pressure printed on the tire sidewall. Check pressure monthly and before long trips; under-inflation by 20% can reduce tread life by 25%.
