Check a different size against this vehicle
Type any tire size below; we'll compute its overall-diameter delta against the OEM 225/50R17 and verdict using the ETRTO ±3% rule.
Common upgrade paths
- Plus-1: 225/45R18; one rim size up, 0.44% OD change. Sharper steering, mild ride penalty, modest cost premium.
- Plus-2: 195/45R19; two rim sizes up, 0.20% 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 2009 acura TSX base-model
The 2009 Acura TSX Base-Model ships from the factory on 225/50R17 tires mounted on R17 wheels. Only one approved fitment is documented for this model year, so replacement options should match the original size exactly unless a plus-size upgrade is being considered. The Compatible alternative sizes table above lists every safe substitution within the ETRTO ±3% overall-diameter tolerance.
Tire choice on the Acura TSX 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 2009 Acura TSX Base-Model 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 2009 Acura TSX Base-Model, 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.

THE TIRE PRESSURE MONITORING SYSTEM (TPMS) GOES OFF 2-10 TIMES A MONTH SAYING "SYSTEM FUNCTION ERROR" AND ALL WHEELS ON THE VEHICLE SHOW A PRESSURE OF "--" VERSUS THE NORMAL DISPLAY OF THE PSI IN THE TIRES. DEALERS TELL ME NOTHING IS WRONG AND PROBLEM ISN'T REPRODUCIBLE.
The contact owns a 2013 Acura TSX equipped with Continental Tires, Tire Line: Pure Contact, Tire Size: 225/50/R17, DOT Number: VY40WD4A2320. The contact stated that while his wife was driving at an undisclosed speed, the front driver's side tire exploded. The vehicle was taken to the dealer; however, the dealer was unable to determine the cause of the failure. The manufacturer was made aware of the failure. The tires were replacement tires. The failure mileage was approximately 126,500.
I first reported this on July 7, 2023 under NHTSA ID#11530893. My wife was driving when the Continental tire size 225/50/R17 suddenly blew out at approximately 70 MPH. Immediately pulled to shoulder of highway. This was a very tense moment at speed running on the rim to get immediately off the road. Fortunately there was no vehicles in neighboring lanes as we swerved and got out of harms way. Continental Tire dealer was contacted and shown the 2 pieces of separated tire. We were informed an open recall for tread separating from side wall of Continental Tires exists. Also informed that my DOT Tire identifier was not listed under the recall. No recourse was taken/offered by Continental dealer.
