The 2017 Acura ILX sits in the compact luxury sport-sedan category, blending Acura’s everyday usability with sharper styling and a more athletic road feel than many entry-level rivals. Tire fitment on this model is straightforward once the exact trim is confirmed, because the ILX uses one of two radial sizes: 215/45R17 or 225/40R18. That makes wheel diameter the first thing to verify, especially between the Base model and the w/A-Spec Pkg. setup. Available choices lean toward modern blackwall performance-oriented radials from BFGoodrich and Nitto, with several series offered in each size. The right pick comes down to matching the correct wheel, preserving the intended stance, and choosing the tire character that suits how the car is driven.
Which Tire Size Is Right for The 2017 Acura ILX
The 2017 Acura ILX uses two primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. The Base model uses a 17-inch setup, while the w/A-Spec Pkg. uses an 18-inch setup, so confirming the car’s wheel size is the first step before comparing tire options. Once that is settled, the decision shifts to choosing among the available radial tire series and product characteristics within the proper size.
215/45R17 is a metric radial size in which 215 identifies nominal section width in millimeters, 45 is the aspect ratio, R indicates radial construction, and 17 is the wheel diameter in inches. On the 2017 Acura ILX, this size belongs to the 17-inch fitment used on the Base model and keeps the tire choice in a modern low-profile radial format. Available options are centered on BFGoodrich blackwall tires across the g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A series. This size is the right place to focus when the car retains its original 17-inch wheel setup and the goal is to stay with the intended fitment profile.
225/40R18 is a metric radial size that uses a 225-millimeter nominal section width, a 40-series aspect ratio, radial construction, and an 18-inch wheel diameter. For the 2017 Acura ILX, this size applies to the w/A-Spec Pkg. configuration, making it distinct from the 17-inch Base model fitment. Product choices include blackwall tires from BFGoodrich and Nitto, with series such as g-Force Sport Comp 2, g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. This is the size to evaluate when the car has the 18-inch wheel package and the buyer wants to compare tire character within that lower-profile setup.
Sub-model fitment matters on the 2017 Acura ILX because tire size changes with the wheel package. The Base model and the w/A-Spec Pkg. do not share the same setup, so identifying the exact trim is essential before selecting a tire.

2017 Acura ILX Base
The 2017 Acura ILX Base uses the 215/45R17 radial fitment on a 17-inch wheel. Tire selection for this version centers on staying with the proper 17-inch size while comparing available blackwall performance-oriented radial series within that specification.
The 2017 Acura ILX w/A-Spec Pkg. uses the 225/40R18 radial fitment on an 18-inch wheel. Choosing for this sub-model starts with confirming that 18-inch setup, then comparing the available blackwall radial options from BFGoodrich and Nitto in the correct size.
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.

Owners shopping tires for a 2017 Acura ILX usually need to confirm the correct size by sub-model, then compare 17-inch versus 18-inch fitment, tire series, and wheel compatibility. The questions below focus on those practical decisions, along with inspection and road-use checks.
Tire Size & Fitment
What tire size fits a 2017 Acura ILX?
The 2017 Acura ILX uses two tire sizes depending on sub-model. The Base model uses 215/45R17, while the w/A-Spec Pkg. uses 225/40R18. Both are radial tire fitments, but they are tied to different wheel diameters, so they are not simply alternate sizes for the same setup.
The practical first step is confirming which wheels are actually on the car. A used ILX may have been fitted with different factory-style wheels or aftermarket replacements, so checking the current rim diameter before choosing tires helps avoid ordering the right type in the wrong size.
What size rim does a 2017 Acura ILX use?
A 2017 Acura ILX uses either a 17-inch or 18-inch rim, depending on the sub-model. The Base model is paired with 215/45R17 tires on a 17-inch wheel, and the w/A-Spec Pkg. uses 225/40R18 tires on an 18-inch wheel. The tire size itself tells you the intended rim diameter in the final number.
That rim diameter needs to match exactly before a tire can be mounted. Wheel width also matters, especially on low-profile radial sizes like these, so the tire choice should be checked against the actual wheel dimensions on the car rather than relying only on trim name or appearance.
Do all 2017 Acura ILX sub-models use the same tire size?
No. The 2017 Acura ILX Base and the 2017 Acura ILX w/A-Spec Pkg. use different tire sizes. The Base model uses 215/45R17, while the w/A-Spec Pkg. uses 225/40R18. Both are radial fitments, but they belong to different wheel packages and should be treated as distinct applications.
That difference affects more than just the tire label. It changes the wheel diameter, the tire profile, and the set of available product choices, so the correct approach is to identify the exact sub-model and confirm the wheels on the car before narrowing down brand or series preferences.
Choosing the Right Tire
What should I consider when choosing a tire for a 2017 Acura ILX?
Start with the correct size for the exact sub-model: 215/45R17 for the Base model or 225/40R18 for the w/A-Spec Pkg. After size is confirmed, compare construction, rim-width compatibility, load figures where stated, and the character of the available tire series. On this ILX, the choices are all radial blackwall tires.
From there, the decision becomes more about how the car is used. A daily-driven ILX may call for one balance of characteristics, while a car used more selectively may lead the owner toward a different series within the same size. Matching the tire to the actual wheel is still the most important checkpoint.
What brands offer tires for the 2017 Acura ILX?
The available tires for the 2017 Acura ILX come from BFGoodrich and Nitto. BFGoodrich covers both ILX sizes with several g-Force series, while Nitto appears in the 225/40R18 fitment with the NT555 G2. That gives the 18-inch application a broader brand comparison than the 17-inch setup.
Brand choice should still come after fitment confirmation. Once the car’s wheel diameter and tire size are verified, comparing brand offerings makes more sense because you can focus on the series, load details, and rim-width suitability that actually apply to your specific ILX configuration.
What tire series are available for the 2017 Acura ILX?
The 2017 Acura ILX is offered with several tire series depending on size. BFGoodrich options include g-Force Sport Comp 2, g-Force Comp 2 AS, and g-Force Phenom T/A, while the 225/40R18 fitment also includes the Nitto NT555 G2. All of these are radial blackwall tires in modern low-profile sizes.
Series selection matters because it is one of the main ways to compare the tires once the size is settled. A useful approach is to narrow the choice by sub-model first, then compare the available series within that size alongside wheel-width compatibility and any load information that is relevant to the car.
Restoration & Appearance
Which tire should I choose for a period-style 2017 Acura ILX?
A period-style approach on a 2017 Acura ILX starts with keeping the correct factory-era sizing format for the exact sub-model. That means 215/45R17 on the Base model or 225/40R18 on the w/A-Spec Pkg., both in radial construction. The available choices are all blackwall tires, which suit the ILX’s modern sport-sedan presentation.
Appearance on a newer collector car often comes down to preserving the proper wheel-and-tire proportion rather than chasing vintage-style sidewall treatments. Keeping the correct wheel diameter and profile has the biggest visual effect, especially if the car is being maintained close to its original trim configuration.
Does correct tire fitment matter for a 2017 Acura ILX restoration?
Yes, correct tire fitment matters because the 2017 Acura ILX uses two distinct size-and-wheel combinations. Staying with the proper 215/45R17 or 225/40R18 setup helps preserve the car’s intended stance and keeps the proportions in line with the sub-model’s original design. Even on a newer vehicle, fitment affects appearance immediately.
A restoration-oriented owner should verify the current wheels before ordering tires, since wheel swaps are common on later-model cars. Keeping the proper rim diameter, tire size, and overall presentation usually does more for an ILX’s authentic look than making a decision based only on brand preference.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2017 Acura ILX?
Yes. Modifications such as aftermarket wheels, suspension changes, lowering, or body alterations can affect tire fitment on a 2017 Acura ILX even when the tire size matches a factory application. This matters because the ILX already uses relatively low-profile 17-inch and 18-inch radial sizes that depend on proper wheel dimensions and clearance.
Checking the actual wheel diameter and width is the first step, followed by a look at steering lock, inner clearance, and fender room. Any change from the original wheel package can alter how a 215/45R17 or 225/40R18 tire sits on the car, so visual confirmation before mounting is worthwhile.
What should I inspect before driving a 2017 Acura ILX on new tires?
Before driving a 2017 Acura ILX on new tires, inspect the wheels for the correct diameter and condition, confirm that all four tires match the intended fitment, and check for proper inflation. It is also smart to look over the suspension and alignment condition, since uneven wear or poor tracking can shorten tire life quickly.
A short, careful test drive should include listening for rubbing, feeling for vibration, and checking that the steering returns normally. After that first drive, recheck air pressure and inspect the sidewalls and tread surfaces again so any mounting or clearance issue can be caught early.
How often should tires on a 2017 Acura ILX be inspected?
Tires on a 2017 Acura ILX should be inspected regularly, not just when tread looks low. Low-profile radial tires can show the effects of potholes, curb contact, air loss, or alignment problems quickly, so it is worth checking pressure, tread condition, and sidewalls on a routine basis rather than waiting for a problem.
A practical habit is to inspect before longer drives and anytime the car feels different on the road. Watch for cracking, bulges, cuts, or uneven wear, and pay extra attention if the ILX sits for long periods or uses larger aftermarket wheels that may change the margin for clearance or ride harshness.
