Check a different size against this vehicle
Type any tire size below; we'll compute its overall-diameter delta against the OEM 225/50R18 and verdict using the ETRTO ±3% rule.
Common upgrade paths
- Plus-1: 225/45R19; one rim size up, 0.43% OD change. Sharper steering, mild ride penalty, modest cost premium.
- Plus-2: 195/45R20; two rim sizes up, 0.19% 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 2017 acura TLX
The 2017 Acura TLX ships from the factory on 225/50R18 tires mounted on R18 wheels. 5 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 Acura TLX 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 2017 Acura TLX 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 2017 Acura TLX, 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.

In owners' own words
Verbatim excerpts from complaints filed with NHTSA about Acura TLX. Reports are published by NHTSA as filed and are lightly cleaned here only to remove intake codes.
I currently have Kumho Ecsta PS91 tires on my 2021 Acura TLX that was purchased brand new and 3 out of 4 tires have cracks/splits all the way around the inside and outside sidewall. My vehicle currently has 30k miles and still has plenty of tread left on them as they are rated for 45k miles. Car has always had its routine maintenance done at Acura and tires are always checked and rotation is done also. Please look into this immediately 🙏 I was traveling on an Interstate at 70 mph and this could have been a tragedy for myself and others traveling. Also have pictures to show if needed
Tire size 225/55R17. - Sidewall separation on the inside portion of two tires (unable to identify from looking at tires on vehicle, this could go unnoticed by the driver). No tires were removed from Acura. I do have photos of this safety hazard. - Tires could have blown out while driving and a crash occurring injuring driver or other vehicles on the road. After seeing the tire separation they technicians advised not to drive car vehicle safety hazard. - Unknown if problem was able to be reproduced. - Tire was not inspected by any representative only Acura dealership technicians. - Yes, there were symptoms, when driving at low speeds under 20 mph a squeaky noise was heard, as speed increased the noise was more frequent.
