The 2018 Acura NSX brought the nameplate back as a modern hybrid supercar, blending sharp response, advanced chassis technology, and everyday drivability in a way that set it apart from more traditional exotic machinery. Its staggered tire fitment is a central part of that character. The 2018 Acura NSX uses a 245/35R19 radial up front and a 305/30R20 radial at the rear, so tire selection starts with keeping the front and rear positions straight. Available choices include blackwall performance radials, along with rear options in raised white letter or redline form. For any NSX, the right decision balances correct staggered sizing, wheel compatibility, appearance, and intended road use.
Which Tire Size Is Right for The 2018 Acura NSX
The 2018 Acura NSX uses two primary tire sizes, with one size assigned to the front and another to the rear. Those sizes also use different rim diameters, so the first step is confirming wheel position and wheel diameter before choosing a tire. Once that is settled, the decision shifts to comparing the available radial options by brand, series, and sidewall style.
245/35R19 is a modern metric radial size in which 245 identifies nominal section width in millimeters, 35 is the aspect ratio, R indicates radial construction, and 19 is the rim diameter in inches. On the 2018 Acura NSX, this size is used at the front, where maintaining the correct front fitment is important to the car's staggered setup. Available choices in this size include BFGoodrich and Nitto blackwall performance radials across the g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2 series. This is the size to evaluate when replacing worn front tires while keeping the proper front wheel diameter and overall sizing relationship intact.
305/30R20 is a modern metric radial size in which 305 identifies nominal section width in millimeters, 30 is the aspect ratio, R marks radial construction, and 20 is the rim diameter in inches. On the 2018 Acura NSX, this size is used at the rear, matching the car's wider rear-tire requirement and larger rear wheel diameter. Available rear tire choices include Nitto and Pro-Trac products, with blackwall, raised white letter, and redline sidewall treatments represented in the current assortment. This is the size to focus on when replacing rear tires and preserving the NSX's correct staggered front-to-rear fitment layout.
Fitment on the 2018 Acura NSX is straightforward, but it is split by position rather than by trim variation. Checking whether you are selecting for the front or rear matters because the NSX uses different sizes and different rim diameters at each end.

2018 Acura NSX Base Front
The 2018 Acura NSX Base Front uses the front-specific radial fitment for the car's staggered setup. Tire selection here centers on preserving the correct front sizing while comparing available blackwall performance options by brand and tire series.
The 2018 Acura NSX Base Rear uses the wider rear radial fitment and a larger wheel diameter than the front. That makes rear tire choice partly a fitment question and partly an appearance decision, since blackwall, raised white letter, and redline options are available.
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 2018 Acura NSX?
The 2018 Acura NSX uses a staggered tire setup with 245/35R19 at the front and 305/30R20 at the rear. Both are radial sizes, and each one belongs to a specific end of the car rather than serving as a universal all-around fitment.
That means the first step is confirming whether you are replacing front tires, rear tires, or a full set. Since the NSX also uses different wheel diameters front and rear, the correct size choice depends on wheel position, actual wheel dimensions, and whether the car still has its intended staggered layout.
What size rim does a 2018 Acura NSX use?
The 2018 Acura NSX uses two rim diameters as part of its staggered setup: 19-inch rims at the front and 20-inch rims at the rear. Those diameters match the primary tire sizes 245/35R19 and 305/30R20.
Wheel diameter needs to be confirmed before selecting tires, especially on a car that may have seen aftermarket wheel changes. Once the front 19-inch and rear 20-inch fitment is verified, it becomes much easier to compare the available radial choices in the correct size for each position.
Why does the 2018 Acura NSX have more than one tire size?
The 2018 Acura NSX has more than one tire size because it uses a staggered front-and-rear fitment. The front uses 245/35R19, while the rear uses the wider 305/30R20, and each size is paired with its own wheel diameter.
For the buyer, that means tire selection is tied to axle position rather than trim confusion. Mixing up the front and rear sizes can create an obvious fitment problem, so it is important to match the tire to the correct wheel, confirm the actual wheel setup on the car, and maintain proper clearance at both ends.
Choosing the Right Tire
What should I consider when choosing a tire for a 2018 Acura NSX?
Start with the correct staggered fitment: 245/35R19 for the front and 305/30R20 for the rear. From there, compare the available radial tires by brand, tire series, sidewall treatment, and wheel compatibility so the replacement matches both the car's setup and your intended use.
A full-set replacement may call for a balanced approach between front and rear choices, while single-axle replacement still needs close attention to matching size and wheel position. It also helps to verify the actual wheels on the car, since an NSX with non-stock wheels may need additional checking for rim width, clearance, and overall setup.
What sidewall styles are available for 2018 Acura NSX tires?
Sidewall style depends on size. The available 245/35R19 front tires are blackwall performance radials, while the 305/30R20 rear assortment includes blackwall, RWL, and redline options, giving the rear fitment more appearance variation than the front.
That matters if you want the tires to support a particular visual theme as well as the correct fitment. A blackwall setup keeps the look understated, while raised white letter or redline rear tires add a more expressive presentation. Matching sidewall style to the car's overall appearance is worth considering before choosing by brand or series alone.
What brands offer tires for the 2018 Acura NSX?
The current 2018 Acura NSX tire selection includes BFGoodrich, Nitto, and Pro-Trac. BFGoodrich and Nitto appear in the front 245/35R19 size, while Nitto and Pro-Trac are available in the rear 305/30R20 size.
Brand choice is only one part of the decision, since the available products also differ by tire series and, at the rear, by sidewall style. It helps to narrow the selection by position first, then compare the products that match that specific front or rear requirement rather than treating the full NSX assortment as one interchangeable group.
Restoration & Appearance
How does tire construction affect the appearance of a 2018 Acura NSX?
On the 2018 Acura NSX, construction is straightforward because the primary fitment is radial front and rear. The appearance difference comes less from bias-ply-versus-radial concerns and more from the visual details of the available radial tires, especially sidewall treatment on the rear size.
That means a buyer focused on presentation should look closely at blackwall, raised white letter, or redline choices rather than trying to recreate an earlier vintage-tire look. The best visual match depends on whether the goal is a clean modern supercar appearance or a more customized style that still respects the NSX's staggered fitment.
Does correct tire fitment matter for a 2018 Acura NSX restoration or presentation build?
Correct tire fitment matters on a 2018 Acura NSX because the car's visual stance is closely tied to its staggered front-and-rear sizing. Using the proper 245/35R19 front and 305/30R20 rear sizes helps preserve the intended relationship between wheel diameter, tire profile, and overall proportion.
Appearance-driven builds should also consider sidewall style, since the rear fitment offers more visual variety than the front. If exact originality is important, vehicle-specific documentation and marque expertise are worthwhile references, but even for a presentation-oriented NSX, staying with the correct front and rear size architecture is the right starting point.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2018 Acura NSX?
Yes. Wheel changes, suspension alterations, alignment changes, or body modifications can affect tire fitment on a 2018 Acura NSX, even when the tire sizes remain 245/35R19 front and 305/30R20 rear. A staggered layout leaves less room for assumptions than a same-size setup.
An NSX with aftermarket wheels should be checked carefully for actual wheel diameter, wheel width, and clearance at both steering lock and suspension travel. Lowering or other chassis changes can also alter fender and inner clearance, so the right approach is to verify the full front and rear setup before choosing replacement tires.
What should I inspect before driving a 2018 Acura NSX on new tires?
Before driving a 2018 Acura NSX on new tires, inspect wheel condition, confirm that the front and rear sizes were mounted in the correct positions, and check inflation pressure. It is also smart to look for any interference issues, bead seating concerns, or visible damage that could affect early road use.
A careful walkaround should include tread and sidewall inspection, valve stem condition, and a quick check for uneven ride height or unusual clearance at the front and rear. After the first short drive, recheck pressure and look again for rubbing or irregular wear signs, especially if the car has non-standard wheels or suspension changes.
How often should tires on a 2018 Acura NSX be inspected?
Tires on a 2018 Acura NSX should be inspected regularly, especially before spirited driving, longer trips, or after the car has been parked for extended periods. A visual check for cuts, bulges, cracking, uneven wear, and low pressure is a sensible routine on a staggered high-performance setup.
Low-use performance cars can age tires even when tread still looks acceptable, so condition matters as much as remaining depth. It helps to monitor air loss, look for changes in wear pattern between front and rear, and keep storage conditions as stable as possible to reduce exposure to heat, sunlight, and moisture.
