Check a different size against this vehicle
Type any tire size below; we'll compute its overall-diameter delta against the OEM 255/60R19 and verdict using the ETRTO ±3% rule.
Common upgrade paths
- Plus-1: 255/55R20; one rim size up, -0.01% OD change. Sharper steering, mild ride penalty, modest cost premium.
- Plus-2: 255/50R21; two rim sizes up, -0.03% OD change. Noticeable ride penalty, higher pothole risk, meaningful tire-cost premium.
Use the plus-size calculator to evaluate any rim step against the OEM size.
How to choose tires for the 2014 GMC acadia
The 2014 GMC Acadia ships from the factory on 255/60R19 tires mounted on R19 wheels. 3 approved fitments are documented for this model year, allowing some flexibility between performance, comfort, and winter compounds. The Compatible alternative sizes table above lists every safe substitution within the ETRTO ±3% overall-diameter tolerance.
Tire choice on the GMC Acadia comes down to three trade-offs that matter more than brand loyalty: load index (must equal or exceed the OEM number), speed rating (must match or exceed the placard), and UTQG treadwear (higher means longer life, lower usually means stickier rubber). Owners replacing factory tires with the same compound class, for example all-season for all-season, generally see no change in ride characteristics or fuel economy. Switching categories (performance summer to all-season touring, for example) is where the trade-offs show up at the contact patch.
For 2014 GMC Acadia owners considering a plus-size upgrade, the safer option is a Plus-1 step (one rim size up with a 10-point aspect drop and ~10 mm of additional section width). Plus-2 is technically viable on this chassis if the alternative-sizes table lists a Plus-2 candidate within tolerance, but expect a meaningful ride-harshness penalty and a tire-cost premium of 30–60% per tire relative to the OEM fitment. For winter use the recommended pattern is one width step down (e.g. from a 235 to a 225) with the aspect ratio bumped up to preserve overall diameter; narrower tires apply higher contact pressure per square inch on snow, which translates directly into shorter braking distances. The plus-size calculator evaluates any specific rim step against this OEM size.
Before purchasing, verify the tire size on the driver-door placard of your specific 2014 GMC Acadia, since trim levels and option packages can shift the original fitment from what is documented here. The placard reading is the authoritative source per FMVSS 110, and dealers will reference the placard rather than aftermarket catalogs when validating warranty claims.

WAS DRIVING AND TIRE PRESSURE SENSOR WARNING CAME ON AND WAS SHOWING I WAS LOSING PRESSURE SO SLOWED DOWN IN TIME WHERE THE TIRE WAS COMPLETELY FLAT. VALVE STEM WAS CRACKED AND BROKE OFF. TOOK IN TO GET FIXED AND HE FOUND THAT TWO OTHERS WERE CRACKED SO THEY COULD GO BAD AS WELL. LUCKILY WAS NOT ON HIGHWAY WHEN TIRE DEFLATED.
THE CONTACT OWNS A 2014 GMC ACADIA EQUIPPED WITH GOODYEAR FORTERA HL TIRES, SIZE: P255/65R18 109S. AFTER INSPECTING THE VEHICLE, THE CONTACT NOTICED THAT THE TREAD ON THE SIDEWALL OF ALL FOUR TIRES WERE CRACKED. THE VEHICLE NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND STATED THAT THE VIN WAS NOT INCLUDED IN NHTSA CAMPAIGN NUMBER: 15V044000 (TIRES). THE TIRE AND VEHICLE FAILURE MILEAGE WAS 18,537.
THE CONTACT OWNS A 2015 GMC ACADIA EQUIPPED WITH GOODYEAR FORTERA HL TIRES, SIZE: P255/65R18. WHILE THE VEHICLE WAS UNDERGOING ROUTINE MAINTENANCE AT WALLINGFORD BUICK GMC (1122 OLD NORTH COLONY RD, WALLINGFORD, CT 06492, (888) 765-9107), THE CONTACT WAS INFORMED THAT ALL FOUR TIRES HAD CRACKS AND TREAD SEPARATION FROM THE TREAD PATTERNS. THE VEHICLE WAS DEEMED UNSAFE TO DRIVE. THE CONTACT WAS REFERRED TO NHTSA. THE TIRES WERE NOT REPLACED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND DID NOT ASSIST. THE APPROXIMATE TIRE AND VEHICLE FAILURE MILEAGE WAS 30,590.
BOUGHT FIRESTONE ALL SEASON TIRES DOT V60M AL1. TIRES WORN DOWN VERY VERY QUICKLY ALL THE WAY ACROSS IN LESS THAN 5K MILES. VEHICLE ALIGNMENT HAD PREVIOUSLY BEEN DONE A FEW MONTHS PRIOR. DEALER TRIED TO CLAIM IT WAS ALIGNMENT, ALIGNMENT SHOP SAID IT WAS A TIRE ISSUE. I BELIEVE THE TIRES RUBBER HAS A PROBLEM WITH THE COMPOUND FORMULA. FIRESTONE REFUSES TO COVER THE TIRES. SAID THAT EXTREMELY FAST TREADWEAR ISN'T COVERED. IMAGINE THAT! PAID $657.00 FOR A SET OF TIRES THAT WITHIN 5 MONTHS NEED REPLACING. HAD MY WIFE GOT INTO AN ACCIDENT AND BEEN INJURED OR KILLED. I WOULD OF MADE ANOTHER EXAMPLE OUT OF FIRESTONE LIKE WHAT WAS DONE IN THE 90S WHEN FORD EXPLORERS WERE TURNING INTO CRASH DERBY CARS DUE TO DEFECTIVE TIRES MADE BY THIS COMPANY FOR ODDLY A COMPARITIVELY SIZED VEHICLE.
