The 2009 Acura TSX sits in a sweet spot for sport sedan buyers who want crisp handling, clean styling, and everyday drivability without losing a distinctly driver-focused feel. It belongs to an era when Acura balanced comfort and precision in a way that still makes the TSX appealing as a modern enthusiast car. This exact model uses a 225/50R17 radial tire on a 17-inch rim, so the fitment question is straightforward. The real choice comes down to comparing radial performance options from BFGoodrich and Nitto within the correct size and blackwall presentation. For the best result, match the tire to the car's current wheel setup, driving use, and overall condition.
Which Tire Size Is Right for The 2009 Acura TSX
The 2009 Acura TSX uses one primary tire size: 225/50R17, a radial fitment for a 17-inch rim. The 2009 Acura TSX Base uses that same size, so the main decision is not which primary size fits, but which tire within that size best suits the car's wheel setup, handling expectations, and intended road use.
A 225/50R17 size uses modern metric radial sizing: 225 is the nominal section width in millimeters, 50 is the aspect ratio, R identifies radial construction, and 17 is the wheel diameter in inches. On the 2009 Acura TSX, that means a contemporary sport sedan fitment built around a 17-inch rim and radial-road manners. Available choices in this size include BFGoodrich and Nitto blackwall tires across g-Force Comp 2 AS, g-Force Sport Comp 2, and NT555 G2 series. This size is the right place to focus if the car retains its original wheel diameter and you want to compare road-use character within the proper fitment.
Tire fitment is simple across the covered 2009 Acura TSX sub-models. The Base model uses the same primary size, so checking the sub-model mainly confirms that you can concentrate on product choice rather than sorting through multiple factory fitments.

2009 Acura TSX Base
The 2009 Acura TSX Base uses the same 225/50R17 radial tire fitment as the model core. That keeps selection focused on comparing available blackwall radial options, confirming the 17-inch wheel setup, and making sure any wheel or suspension changes have not altered the car's current tire requirements.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Tire Size & Fitment
What tire size fits a 2009 Acura TSX?
The 2009 Acura TSX uses a 225/50R17 radial tire. That is the primary fitment for this model and it is the same size used on the 2009 Acura TSX Base, keeping the factory-style sizing straightforward for most owners.
Using the correct size is only the first step. It is still worth confirming that the car has 17-inch wheels and has not been changed with aftermarket rims, suspension modifications, or clearance-affecting body changes. Once the wheel setup is confirmed, the decision becomes which 225/50R17 tire best matches your driving priorities.
What size rim does a 2009 Acura TSX use?
The 2009 Acura TSX tire fitment is built around a 17-inch rim. The primary tire size, 225/50R17, is a 17-inch radial size, and the available products in this fitment are also matched to 17-inch wheel diameter.
Wheel diameter should never be assumed from appearance alone, especially on a car that may have changed hands or been modified. Check the actual wheel size stamped on the rim or verify it from the current setup before ordering tires. Diameter must match exactly, and rim width should also fall within the usable range for the specific tire you choose.
Does the 2009 Acura TSX Base use the same tire size?
Yes. The 2009 Acura TSX Base uses the same 225/50R17 radial tire size as the core 2009 Acura TSX fitment. That means there is no separate primary factory-style tire size to sort through for the Base sub-model.
Even with shared fitment, the smartest next check is the car itself rather than the badge. A TSX Base with replacement wheels, altered ride height, or prior owner changes may need closer measurement before a new set is selected. On an unmodified 17-inch setup, you can focus on comparing tire series, load-related specs, and intended road use.
Choosing the Right Tire
What should I consider when choosing a 225/50R17 tire for a 2009 Acura TSX?
Start with the correct fitment: 225/50R17 on a 17-inch wheel. From there, compare construction details within the available radial options, including rim-width compatibility, load-related specifications, tire weight, and the kind of road feel or usage character suggested by each tire series.
The 2009 Acura TSX responds best when the tire matches the car's actual setup and intended use. A daily-driven sedan, a sharper-handling weekend car, and a TSX with upgraded wheels may point you toward different choices within the same size. Checking wheel width and reviewing the product specs side by side helps narrow the selection intelligently.
What brands offer tires for the 2009 Acura TSX?
BFGoodrich and Nitto offer tires in the 225/50R17 fitment used by the 2009 Acura TSX. In this size, BFGoodrich appears in more than one g-Force series, while Nitto offers the NT555 G2, giving TSX owners a few distinct radial performance-oriented choices.
Brand alone should not decide the purchase. It makes more sense to compare each tire's series, load-related specs, weight, and approved rim-width range against the way the TSX is actually used. That approach is especially helpful if the car sees a mix of commuting, spirited driving, or non-original wheel configurations.
What tire series are available for the 2009 Acura TSX?
The 2009 Acura TSX fitment includes BFGoodrich g-Force Comp 2 AS, BFGoodrich g-Force Sport Comp 2, and Nitto NT555 G2 in the correct 225/50R17 size. All are radial blackwall tires for a 17-inch wheel, but they are presented as distinct series rather than one interchangeable product type.
Comparing series is useful because it helps separate appearance from actual spec differences. Two tires can share the same size yet vary in weight, load-related rating details, and wheel-width suitability. For a TSX owner, the best next step is to compare the product specifications closely and match them to the car's current wheels and expected driving style.
Restoration & Appearance
Which tire should I choose for a period-style 2009 Acura TSX?
A period-style 2009 Acura TSX still starts with the correct 225/50R17 radial size on a 17-inch wheel. Since the available choices are modern blackwall radials, the visual decision is fairly clean and understated, which suits the TSX's original-era sport sedan character better than trying to force a vintage-looking presentation.
For a car being kept close to its original-era appearance, avoid drifting away from the proper size just to chase a different look. Focus instead on maintaining the right proportions, confirming the wheel diameter, and selecting a tire series that matches the car's intended use. That keeps the TSX visually balanced without introducing an obviously off-size tire.
Does correct tire fitment matter for a 2009 Acura TSX restoration?
Yes, correct tire fitment matters on a 2009 Acura TSX restoration because tire size strongly affects stance, wheel-to-tire proportion, and overall presentation. Keeping the car in its proper 225/50R17 radial fitment helps preserve the look and functional balance expected from this generation of TSX.
Appearance is only part of the equation. The right fitment also supports sensible clearance, proper wheel matching, and predictable road manners for a restored street-driven car. If originality matters at a finer level, verify wheel and trim details on the car itself before choosing among the available 225/50R17 product options.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2009 Acura TSX?
Yes. A 2009 Acura TSX may have started with a 225/50R17 fitment, but aftermarket wheels, different wheel offsets, lowered suspension, spring changes, or body modifications can all change the space available for the tire and alter what works on the car now.
That makes it important to inspect the actual setup before replacing tires, especially on a used TSX with unknown changes. Confirm wheel diameter and width, then check for clearance at the fender, suspension, and steering range. Even when staying with 225/50R17, a modified car should be evaluated as it sits rather than assumed to match stock.
What should I inspect before driving a 2009 Acura TSX on new tires?
Before regular road use, inspect the wheel condition, verify that the tire size matches the car's 17-inch setup, and make sure the tires are properly installed and inflated. It is also smart to check for suspension wear, alignment issues, and any rubbing marks that suggest existing clearance problems.
A quick visual once-over is not enough on a sport sedan like the TSX. Look for uneven old-tire wear that could point to alignment or bushing issues, and confirm that the new tires clear through full steering travel. Taking care of those checks early helps the 225/50R17 fitment perform as intended instead of masking another chassis problem.
How often should tires on a 2009 Acura TSX be inspected?
Tires on a 2009 Acura TSX should be inspected regularly, not just when tread looks low. Frequent checks for air pressure, uneven wear, cuts, bulges, and sidewall damage are especially worthwhile on a car that may see spirited driving, long commutes, or periods of sitting between uses.
Monthly visual checks are a sensible baseline, with closer inspection before longer trips or after any noticeable change in ride, steering, or vibration. Pay extra attention if the TSX has been parked for extended periods, since age and storage conditions matter as much as mileage. Catching problems early protects both tire life and overall drivability.
