Check a different size against this vehicle
Type any tire size below; we'll compute its overall-diameter delta against the OEM 225/55R17 and verdict using the ETRTO ±3% rule.
Common upgrade paths
- Plus-1: 245/45R18; one rim size up, -0.24% OD change. Sharper steering, mild ride penalty, modest cost premium.
- Plus-2: 245/40R19; two rim sizes up, -0.10% 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 2010 buick regal
The 2010 Buick Regal ships from the factory on 225/55R17 tires mounted on 7x17 wheels. 2 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 Buick Regal 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 2010 Buick Regal 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 2010 Buick Regal, 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.

I AM AN AUTO MECHANIC AND LATER AUTOMOTIVE ENGINEER AND I ALWAYS KEEP MY TIRES PROPERLY INFLATED WITH ROUTINE BALANCING, ROTATION AND ALIGNMENTS. IN OVER 30 YEARS OF DRIVING I HAD NEVER HAD A TIRE ISSUE BEYOND THE OCCASIONAL FLAT UNTIL I BOUGHT A SET OF GOODYEAR VIVA 2 TIRES FROM WALMART ON MAY 31, 2011. P225/60R16 97S DOT MDX0 H6HP 1911 TIRES FOR MY 2001 BUICK REGAL. AFTER ALMOST A YEAR I NOTICED THE CAR WAS NOT RIDING SMOOTHLY SO I TOOK IT IN TO GET THE TIRES BALANCED. THE TIRE MAN SHOWED ME THAT THERE WAS A TREAD ISSUE ON A TIRE, SO ON MAY 9, 2012 I BOUGHT A REPLACEMENT VIVA 2 TIRE. THE FAILED TIRE HAD LESS THAN A YEAR AND 17,601 MILES ON IT. RECENTLY WHILE DRIVING ON THE FREEWAY ANOTHER OF THE INITIAL VIVA 2 TIRES BLEW OUT (SAME DOT CODE). THIS TIRE WAS ABOUT 26 MONTHS OLD WITH 31,440 MILES ON IT. I STILL HAVE THIS TIRE IF YOU WANT TO INSPECT IT.

Also, later the front passenger's side tire developed bubbles and had to be replaced. Within the first 200 miles of driving the vehicle, a dealer employee experienced a blowout of the front passenger's side tire. The contact stated that the vehicle was equipped with the tires when it was purchased new. The contact stated that three of the four tires had experienced a failure. The contact was informed that the tire size was not included in the NHTSA Campaign Number: 21T001000 (Tires). The failure mileage was 200.
