The 2020 Acura NSX blends supercar performance with a distinctly modern take on Acura engineering, making tire fitment more than a cosmetic choice. Its staggered setup is central to the car’s balance, with 245/35R19 up front and 305/30R20 at the rear, both in radial construction. That means the first decision is not simply size, but confirming front versus rear placement and preserving the intended wheel-and-tire relationship. Available choices also introduce different brand, series, and sidewall directions, especially at the rear. For owners focused on spirited road use, appearance, or maintaining the NSX’s designed stance, exact fitment matters from the start.
Which Tire Size Is Right for The 2020 Acura NSX
The 2020 Acura NSX uses two primary tire sizes, and they serve different positions on the car rather than different trim levels. The front uses a 19-inch radial and the rear uses a 20-inch radial, so the first step is confirming whether you are replacing the front pair, the rear pair, or the complete staggered set before comparing brands, sidewall styles, and tire series.
245/35R19 is a metric radial size in which 245 identifies the nominal section width in millimeters, 35 is the aspect ratio, R indicates radial construction, and 19 is the rim diameter in inches. On the 2020 Acura NSX, this size is used at the front, where preserving the intended staggered relationship with the rear tire is important. Available choices include BFGoodrich and Nitto options in blackwall form, with series such as g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. This is the size to evaluate when front-end response, wheel compatibility, and replacement of the front axle tires are the immediate priority.
305/30R20 is a metric radial size with a 305-millimeter nominal section width, a 30-series profile, radial construction, and a 20-inch rim diameter. On the 2020 Acura NSX, this is the rear tire size, so it plays a major role in maintaining the car’s staggered performance setup and visual stance. Choices in this size include Nitto and Pro-Trac offerings, with blackwall, raised white letter, and redline sidewall treatments available through series such as NT555 G2 and Street Pro III. This is the size to focus on when replacing rear tires and checking that wheel diameter and overall setup remain correct.
Fitment on the 2020 Acura NSX is straightforward in the sense that the same Base configuration is represented, but tire size still varies by position. Checking whether the tire is for the front or rear matters because the NSX uses a staggered arrangement with different sizes and rim diameters.

2020 Acura NSX Base Front
The 2020 Acura NSX Base Front uses the 245/35R19 radial size on a 19-inch wheel position. Tire selection here centers on choosing the right front fitment within that size while keeping the overall staggered relationship with the rear of the car intact.
The 2020 Acura NSX Base Rear uses the wider 305/30R20 radial size on a 20-inch wheel position. Rear tire choice is where sidewall style becomes more visible, so buyers often compare construction details and appearance while still confirming wheel compatibility and clearance.
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.
Best 2020 Acura NSX Tires for Sale

Common 2020 Acura NSX tire questions usually center on the staggered front and rear sizes, wheel diameters, brand and sidewall choices, and what to inspect before road use. The details below focus on exact fitment rather than general sports-car tire advice.
Tire Size & Fitment
What tire size fits a 2020 Acura NSX?
The 2020 Acura NSX uses a staggered tire setup with 245/35R19 at the front and 305/30R20 at the rear. Both are radial sizes, and they are tied to different wheel diameters, so they are not interchangeable from one end of the car to the other.
That means replacement starts with identifying axle position, not just year and model. A front tire must match the 19-inch front wheel, while a rear tire must match the 20-inch rear wheel. If the car has aftermarket wheels or previous tire changes, confirm the actual wheel setup before selecting a replacement.
What size rim does a 2020 Acura NSX use?
The 2020 Acura NSX uses two rim diameters as part of its factory-style staggered layout: 19 inches at the front and 20 inches at the rear. The 245/35R19 tire belongs on the front position, and the 305/30R20 tire belongs on the rear position.
Rim diameter is the first hard fitment check because a 19-inch tire cannot mount on a 20-inch wheel, and a 20-inch tire cannot mount on a 19-inch wheel. It is also worth verifying wheel width and the actual wheel installed on the car, especially if the NSX has been modified or purchased used.
Why does the 2020 Acura NSX have more than one tire size?
The 2020 Acura NSX has more than one tire size because it uses a staggered setup, with a narrower front tire and a wider rear tire. In this application, 245/35R19 serves the front and 305/30R20 serves the rear, each on its own rim diameter.
That layout means tire choice should preserve the intended front-to-rear relationship unless the entire wheel-and-tire package has been deliberately redesigned. Mixing up the positions or trying to treat the car like a square setup can create avoidable fitment problems, so check axle position, wheel size, and clearance before replacing tires.
Choosing the Right Tire
What should I consider when choosing a 2020 Acura NSX tire?
Start with the correct axle position and size, since the 2020 Acura NSX uses 245/35R19 in front and 305/30R20 in the rear. After that, compare radial construction details, brand, tire series, sidewall style, and any available rim-width or load specifications that apply to the size you are replacing.
The right choice depends on whether the goal is maintaining the car’s intended staggered performance setup, emphasizing a cleaner modern look, or adding a more distinctive sidewall treatment at the rear. It also helps to compare the actual wheel on the car, especially if there have been previous changes to wheels, alignment, or suspension height.
What sidewall styles are available for 2020 Acura NSX tires?
Sidewall style varies by size on the 2020 Acura NSX. Blackwall options are available in the front 245/35R19 size, while the rear 305/30R20 size is available in blackwall as well as raised white letter and redline form.
That makes sidewall choice partly an appearance decision and partly a size-specific availability issue. A buyer replacing rear tires has more visible style variation to compare, while front replacement stays more conventional. Sidewall style does not change the need to confirm the proper size, wheel diameter, and overall compatibility with the car’s existing setup.
What brands offer tires for the 2020 Acura NSX?
BFGoodrich, Nitto, and Pro-Trac all offer tires for the 2020 Acura NSX across its two primary sizes. BFGoodrich appears in the 245/35R19 front size, Nitto appears in both front and rear sizes, and Pro-Trac is available in the 305/30R20 rear size.
Brand comparison is most useful when paired with tire series and sidewall treatment rather than viewed in isolation. For example, the front size centers on blackwall performance-oriented radial choices, while the rear size adds visual alternatives such as raised white letter and redline. Matching the tire to the correct axle position remains the first priority.
Restoration & Appearance
Which tire should I choose for a period-style 2020 Acura NSX?
A period-style approach on a 2020 Acura NSX still starts with the original staggered sizing theme: 245/35R19 in front and 305/30R20 in the rear. Since this is a modern performance car rather than an earlier restoration-era vehicle, the appearance decision usually centers more on sidewall treatment and tire series than on bias-ply versus radial construction.
Blackwall tires keep the presentation clean and contemporary, while rear redline or raised white letter options create a more customized look. Owners aiming for the car’s original visual character often stay restrained with sidewall styling, but exact authenticity questions are best settled with marque-specific references and the car’s own delivery configuration.
How does tire construction affect the appearance of a restored 2020 Acura NSX?
Tire construction is less of an appearance divide on a 2020 Acura NSX because the covered fitments are radial throughout. The bigger visual differences come from sidewall presentation, with blackwall offering the most understated look and rear options such as redline or raised white letter adding a more assertive style.
For an owner preserving a low-mile or collector-focused NSX, keeping the correct staggered size relationship usually matters more visually than chasing novelty. A mismatched front-to-rear profile or incorrect wheel diameter can change the car’s stance quickly, so appearance decisions should be made only after size, wheel, and overall fitment have been confirmed.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2020 Acura NSX?
Yes, modifications can affect tire fitment on a 2020 Acura NSX even when the tire sizes themselves look correct. Aftermarket wheels, offset changes, suspension lowering, alignment changes, or body modifications can all influence how 245/35R19 front and 305/30R20 rear tires sit and clear under real driving conditions.
That is why the actual wheel and suspension setup should be checked before assuming a replacement tire will work the same way as the previous one. Steering clearance, inner suspension clearance, and fender clearance all matter on a staggered performance car, particularly when wider rear tires and low-profile sidewalls are involved.
What should I inspect before driving a 2020 Acura NSX on new tires?
Before driving a 2020 Acura NSX on new tires, inspect the wheel size, confirm front and rear tires are mounted in the correct positions, and check tire pressure carefully. It is also wise to look for any mounting damage, visible bead issues, air loss, or contact points that could suggest a clearance problem.
A short initial drive should be followed by another inspection to make sure everything remains stable. Pay attention to steering feel, unusual vibration, and any rubbing noises during turns or suspension movement. On a low-profile staggered setup, small fitment issues can become obvious quickly, so early rechecking is a practical habit.
How often should tires on a 2020 Acura NSX be inspected?
Tires on a 2020 Acura NSX should be inspected regularly, not only by mileage but also by time and storage conditions. Low-use performance cars can still develop pressure loss, sidewall cracking, flat spotting, or age-related deterioration even when tread depth appears to remain strong.
A good routine is to check pressure and visible condition before drives, then carry out a closer inspection at regular intervals for tread wear, cuts, bulges, and uneven wear patterns. Any car that sits for extended periods benefits from extra attention, since storage environment and inactivity can affect tire condition just as much as road use.
