The 2019 Acura NSX blends supercar performance with a distinctly modern approach, pairing hybrid-era engineering and all-wheel-drive capability with a shape that still reads as an Acura halo car. Tire selection on this car is unusually fitment-sensitive because the 2019 Acura NSX uses a staggered radial setup: 245/35R19 in front and 305/30R20 in the rear. That means the decision starts with position on the car, then moves to tire series, brand, and sidewall presentation. Available choices include blackwall designs as well as rear options with raised white letters or redline styling. Owners should match the tire to the correct axle, wheel diameter, and overall appearance goal before road use.
Which Tire Size Is Right for The 2019 Acura NSX
The 2019 Acura NSX uses two primary tire sizes, and they are position-specific rather than interchangeable. A 245/35R19 radial fits the front and a 305/30R20 radial fits the rear, so the first step is confirming which axle you are replacing and matching it to the correct wheel diameter before comparing tire brands, series, and sidewall style.
In 245/35R19, the 245 identifies nominal section width in millimeters, the 35 is the aspect ratio, the R marks radial construction, and the 19 is the wheel diameter in inches. On the 2019 Acura NSX, this is the front tire size, making it part of the car's staggered performance setup rather than a universal four-corner fitment. Available choices in this size come in blackwall form from BFGoodrich and Nitto, with series such as g-Force Comp 2 AS, g-Force Phenom T/A, and NT555 G2. This size should be evaluated as a front-axle fitment with attention to wheel width and matching overall setup.
In 305/30R20, the 305 identifies nominal section width in millimeters, the 30 is the aspect ratio, the R indicates radial construction, and the 20 is the wheel diameter in inches. On the 2019 Acura NSX, this is the rear tire size, so it serves a different role from the narrower 19-inch front tire. Product choices include blackwall, raised white letter, and redline presentations, with offerings from Nitto and Pro-Trac in series such as NT555 G2 and Street Pro III. This size belongs in a rear-axle decision that also considers wheel diameter, appearance preference, and the car's staggered layout.
Fitment on the 2019 Acura NSX is straightforward, but it is split by vehicle position rather than a trim change. Checking whether you are replacing the front or rear tires matters because the NSX uses different radial sizes and different wheel diameters at each end.

2019 Acura NSX Base Front
The 2019 Acura NSX Base Front uses the smaller of the two staggered radial fitments, mounted on the front axle. Tire selection here centers on choosing the correct front size first, then comparing blackwall options by brand, series, and wheel-width compatibility.
The 2019 Acura NSX Base Rear uses the wider rear radial size on a larger wheel diameter than the front. That makes rear tire selection as much about confirming axle position as choosing among available blackwall, raised white letter, or redline presentations.
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 2019 Acura NSX Tires for Sale
Available 2019 Acura NSX tire choices span both staggered sizes, with radial options from BFGoodrich, Nitto, and Pro-Trac. Buyers can compare tire series, blackwall versus rear-only RWL or redline styling, and wheel-width compatibility where it is stated.
These FAQs focus on the staggered tire setup used on the 2019 Acura NSX, including front-versus-rear sizing, wheel diameter, available brands and sidewall styles, and the fitment checks that matter before putting the car back on the road.
Tire Size & Fitment
What tire size fits a 2019 Acura NSX?
The 2019 Acura NSX uses a staggered tire setup with two different radial sizes. The front uses 245/35R19, while the rear uses 305/30R20. Those sizes are tied to different wheel diameters, so they are not simply interchangeable from one end of the car to the other.
That staggered layout means the first question is whether you need a front or rear tire. Matching the correct axle position is just as important as matching the size code, especially on a performance car where wheel diameter, tire width, and overall setup all work together.
What size rim does a 2019 Acura NSX use?
The 2019 Acura NSX uses two rim diameters as part of its staggered setup. The front tire size is built around a 19-inch wheel, and the rear tire size is built around a 20-inch wheel. That front-to-rear difference is a core part of the car's fitment.
Wheel diameter should be confirmed before ordering any replacement tire, especially if the car has changed hands or has been modified. Even when the tire sizes look familiar, the front and rear positions on the NSX require different wheel diameters and should be treated as separate fitment decisions.
Why does the 2019 Acura NSX have more than one tire size?
The 2019 Acura NSX has more than one tire size because it uses a staggered arrangement, with a narrower 245/35R19 radial in front and a wider 305/30R20 radial in the rear. The two sizes serve different positions on the car rather than representing optional versions of the same all-around fitment.
For the owner, that means tire replacement starts with axle location, not just the model name. A front tire choice should stay within the front fitment, and a rear tire choice should stay within the rear fitment, while also accounting for wheel diameter and any non-stock wheel or suspension changes.
Choosing the Right Tire
What should I consider when choosing a 245/35R19 and 305/30R20 tire for a 2019 Acura NSX?
Start with the staggered fitment itself: 245/35R19 belongs on the front and 305/30R20 belongs on the rear. From there, compare construction, brand, tire series, sidewall style, and wheel-width compatibility where it is stated. On the NSX, the right tire choice is really a matched front-and-rear decision rather than a single-size purchase.
Appearance and intended use also matter. Some owners will want a clean blackwall presentation at both ends, while others may prefer rear styling such as raised white letters or redlines. It is also worth checking the actual wheel setup on the car so the chosen tire matches both the position and the wheel it will be mounted on.
What sidewall styles are available for 2019 Acura NSX tires?
Sidewall styling for the 2019 Acura NSX includes blackwall options as well as rear tire choices with raised white letters and redline treatment. The 245/35R19 front options shown here are blackwall designs, while the 305/30R20 rear size adds more visible sidewall presentation choices.
That matters if the car's appearance is part of the goal rather than pure replacement sizing. A blackwall setup keeps a more understated modern look, while RWL or redline styling changes the rear tire's visual character. Owners replacing only one axle should think about how the sidewall treatment will look with the tires already on the car.
What brands offer tires for the 2019 Acura NSX?
Tires for the 2019 Acura NSX are available here from BFGoodrich, Nitto, and Pro-Trac, depending on the size and axle position. BFGoodrich and Nitto appear in the 245/35R19 front size, while Nitto and Pro-Trac appear in the 305/30R20 rear size across different tire series and sidewall styles.
Brand choice should be considered alongside the exact size, the intended position on the car, and the tire's overall presentation. Comparing by series can also help, since the available options are not all the same type of offering even when they share the same nominal size.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2019 Acura NSX?
Yes. Any change to wheel size, wheel width, offset, ride height, or suspension setup can affect tire fitment on a 2019 Acura NSX, even when the tire size itself appears correct. Because the car already uses a staggered front-and-rear arrangement, small setup changes can matter more than they might on a square tire package.
Owners should verify actual wheel diameter and clearance before replacing tires on a modified car. Steering lock, inner clearance, outer fender space, and suspension travel are all worth checking, especially if the NSX has aftermarket wheels or a lowered stance that differs from a standard setup.
What should I inspect before driving a 2019 Acura NSX on new tires?
Before driving a 2019 Acura NSX on new tires, inspect the wheel for damage, confirm the correct front and rear sizes were installed, and check inflation pressure carefully. It is also smart to look at valve stems, tread seating, and the tire sidewalls for any visible issues before the car goes back into regular road use.
A short initial drive should be followed by another quick inspection. Recheck pressure, look for any rubbing or uneven contact, and pay attention to how the car feels at low and moderate speed. On a staggered setup, a simple front-versus-rear mounting mistake can create problems even when every individual tire size looks correct.
How often should tires on a 2019 Acura NSX be inspected?
Tires on a 2019 Acura NSX should be inspected regularly, not just when tread looks worn. Pressure, tread condition, cuts, bulges, punctures, and sidewall damage are all worth monitoring, especially on a low-profile staggered setup where both front and rear tires have distinct roles and cannot simply be rotated front to back.
Cars that are driven less often still need routine checks because age and storage conditions matter too. A collector-owned or low-mile NSX can develop problems from long periods of sitting, so periodic inspection for air loss, cracking, and flat-spotting is just as important as watching tread depth alone.
