Acura NSX Tires

Acura NSX uses staggered front and rear tire sizes, and those pairings changed over time. For 1991-1993, the front size is 205/50R15 on a 15-inch rim and the rear size is 225/50R16 on a 16-inch rim. For 1994-2001, the front size is 215/45R16 on a 16-inch rim and the rear size is 245/40R17 on a 17-inch rim. For 2002-2005, the front size is 215/40R17 and the rear size is 255/40R17, both on 17-inch rims. For 2017-2022, the front size is 245/35R19 and the rear size is 305/30R20.

The key point is that Acura NSX never uses a single same-size setup across the years shown here. Confirm the exact model year first, then verify the actual front and rear wheel diameters on the car, especially if the car has been modified or restored with non-original wheels. Matching only one axle correctly is not enough on an NSX, because the front and rear sizes work as a pair.

Acura NSX uses several front and rear rim diameter combinations across the production years in this listing. Early 1991-1993 cars use 15-inch front and 16-inch rear wheels. From 1994-2001, Acura NSX moves to 16-inch front and 17-inch rear wheels. From 2002-2005, both front and rear use 17-inch wheels, though the tire widths remain staggered. The later 2017-2022 Acura NSX uses 19-inch front and 20-inch rear wheels.

That progression matters because a tire with the correct width and profile still will not fit if the rim diameter is wrong. Check both axles individually rather than assuming the whole car uses one wheel size. This is especially important on Acura NSX cars that may have changed wheels during ownership, because the later combinations are visually similar in profile but not interchangeable at the rim.

On an Acura NSX, 245/35R19 identifies a metric radial front tire size used on 2017-2022 models. The 245 is the section width in millimeters, the 35 is the aspect ratio, meaning the sidewall height is 35 percent of the section width, and the R means radial construction. The 19 at the end is the required rim diameter in inches, so this tire mounts only on a 19-inch wheel.

That code tells you both the tire's dimensions and the wheel size it must match, but it does not tell you whether it belongs on the front or rear axle. Acura NSX uses a staggered setup, so 245/35R19 belongs with the later front fitment only. If you are replacing one tire, compare the sidewall marking to the wheel position before choosing a replacement.

Acura NSX sizes in this listing are all metric radial fitments, and the available products are radial tires rather than tube-type bias-ply applications. One listed Michelin 225/50ZR16 product is marked TL, which indicates a tubeless construction, and the rest of the modern radial sizing follows the same general fitment approach. Nothing in the listed Acura NSX sizes points toward brass-era or tube-required tire construction.

That means Acura NSX owners should focus first on correct size, correct axle position, and correct rim diameter rather than planning around tube-type service. Wheel condition still matters, especially on older first-generation cars, so inspect the rim and valve area carefully during mounting. If the car has aftermarket wheels or unusual hardware, have the assembly checked by a shop familiar with performance fitments.

A 1994 Acura NSX uses a staggered pair that differs from the 1991-1993 cars before it and the 2002-2005 cars after it. The correct front size is 215/45R16 and the correct rear size is 245/40R17. That means a 1994 Acura NSX should have 16-inch front wheels and 17-inch rear wheels if it remains in the listed configuration. The size pairing is specific to that production period and should be treated as a matched front-rear set.

Start by reading the sidewall on the existing tires and then verify the wheel diameters directly, because older performance cars are often changed during ownership. If the current setup does not match the year-based pairing, inspect for wheel swaps before choosing replacements. Acura NSX responds to tire sizing changes more noticeably than many ordinary cars, so accuracy matters on both appearance and drivability.

Acura NSX tire products in this listing are available primarily in blackwall form, with additional RWL and redline sidewall choices in 305/30R20. The RWL and redline options appear in the later rear size used on 2017-2022 Acura NSX models. Earlier listed Acura NSX products in 16-inch, 17-inch, and 19-inch fitments are blackwall only. Sidewall style therefore depends on both the size and the production period of the car.

Blackwall remains the most consistent visual choice if you are trying to preserve a clean, factory-like performance look across most Acura NSX years shown here. The RWL and redline options offer a more customized appearance and are relevant only where that 20-inch rear size applies. Always match sidewall style with the intended presentation of the car rather than assuming every style is available in every Acura NSX fitment.

Acura NSX tires in the listed available sizes come from BFGoodrich, Michelin, Nitto, Vredestein, and Pro-Trac. BFGoodrich appears across several of the 16-inch, 17-inch, and 19-inch fitments, while Michelin is listed in 225/50R16. Nitto appears in 255/40R17, 245/35R19, and 305/30R20, Vredestein is listed in 255/40R17, and Pro-Trac appears in 305/30R20. Brand availability depends on the exact front or rear size rather than the Acura NSX name alone.

The practical takeaway is to identify the exact axle size first and then compare the brands offered in that size. Front and rear choices may not come from the same maker across every year range, especially on later staggered applications. If consistent appearance or matching performance family matters to you, review both axle sizes together before deciding on a replacement set.

Acura NSX products here span several modern radial series, including g-Force Sport Comp 2, g-Force Comp 2 AS, Michelin Pilot Sport, g-Force Phenom T/A, Nitto NT555 G2, Sprint Plus, and Street Pro III. Those series represent different modern performance-tire families rather than period bias-ply or antique construction categories. Some are clearly performance-oriented summer-style offerings, while others, such as the all-season g-Force Comp 2 AS, indicate a broader-use approach within the available Acura NSX fitments.

Series choice matters after size and rim diameter are settled. Acura NSX owners who prioritize a closer-to-original visual presentation will usually focus on size correctness and blackwall appearance first, while drivers who actually use the car may compare series based on intended road use and seasonal flexibility. The important part is to keep the correct staggered dimensions for the specific Acura NSX generation.

An Acura NSX should be stored on clean, properly inflated tires in a cool, dry, dark environment away from direct sunlight, electric motors, welders, and ozone-producing equipment. Keep the car off contaminated concrete if possible, and avoid long exposure to petroleum products, solvents, or standing moisture around the tire sidewalls and tread. If the Acura NSX will sit for long periods, rolling the car occasionally helps prevent flat-spotting on performance radials.

Storage habits matter on an Acura NSX because the car uses low-profile staggered tires that can show age and flat-spotting more quickly than taller touring tires. If the car will be inactive for an extended season, inspect pressures regularly rather than leaving it untouched. Owners who keep multiple wheel sets should label front and rear positions clearly, since Acura NSX fitments are axle-specific and not interchangeable.

Tires on an Acura NSX should be inspected before regular driving and again after long storage, paying close attention to air pressure, sidewall cracking, punctures, uneven wear, and any impact damage. Because Acura NSX uses staggered high-performance sizes, inspect both axles individually rather than assuming wear patterns will match. Wheels and valve stems also deserve a close look, especially on first-generation cars that may see intermittent collector use.

Frequent inspection helps catch problems that do not always appear as simple tread wear. A front tire issue on an Acura NSX may not mirror the rear, and low-profile rear tires can hide damage until the car is moved or loaded. If the car has been parked for months, perform the inspection before the first drive instead of discovering a problem once the car is already on the road.

An Acura NSX tire should be replaced when age, cracking, hardening, impact damage, repeated air loss, or structural concerns appear, even if the tread still looks usable. Collector cars often accumulate less mileage than ordinary transportation, so tread depth alone is not a reliable measure of service life. Low-use performance tires can age out long before they wear out, and sidewall condition is especially important on Acura NSX fitments with short sidewalls.

The practical rule is to treat visible aging and driveability changes as replacement triggers, not just worn tread bars. If the car feels harsh, tramlines unusually, or has sat for extended periods, inspect the tires carefully before continued use. Replacing aged tires in matching front and rear pairs for the correct Acura NSX generation is usually the safest way to preserve predictable handling.

The Acura NSX uses distinct size pairings by production period rather than one single tire specification across all years covered here. Early 1991-1993 cars use 205/50R15 front and 225/50R16 rear, 1994-2001 cars use 215/45R16 front and 245/40R17 rear, 2002-2005 cars use 215/40R17 front and 255/40R17 rear, and 2017-2022 cars use 245/35R19 front and 305/30R20 rear. Available replacement products are modern radial offerings from several brands and performance series.

For restoration work, the key is to match the tire size pairing to the exact Acura NSX production period first. If the goal is concours-level accuracy, compare the car against factory literature, original photographs, and marque-specific records in addition to using the size information here. Wheel diameter, sidewall profile, and overall stance all influence whether an Acura NSX looks right when completed.

Correct tire fitment can affect both presentation and judging on an Acura NSX because wheel diameter, sidewall proportion, and staggered front-rear sizing are part of the car's visual and functional identity. A first-generation Acura NSX with the wrong front or rear diameter will usually look off to an informed judge or enthusiast, even before the car is driven. Later Acura NSX cars are equally dependent on proper stagger and profile to preserve the intended appearance.

For owners concerned with value, proper size selection helps the car present as coherent and era-appropriate rather than modified by accident. Judging standards vary, so marque clubs and model specialists remain the best reference for final authenticity decisions. Even on a driver-quality Acura NSX, the right tire dimensions help preserve the car's proportions and keep the restoration from being undermined by an obviously incorrect stance.

Blackwall is the sidewall style most consistently available across Acura NSX tire products in the listed sizes, and it is the style present in the 16-inch, 17-inch, and 19-inch fitments shown here. The 305/30R20 rear size also includes RWL and redline options, but those are limited to that later application. For most Acura NSX restorations or factory-looking refurbishments, blackwall is the straightforward period-appropriate direction within the sizes covered here.

Sidewall choice should follow the intended presentation of the car rather than novelty alone. A clean blackwall usually suits the restrained, technical appearance associated with Acura NSX, while RWL or redline choices create a more custom visual statement on later cars. If originality matters, compare your wheel and tire presentation to marque references and period photography before finalizing the look.

The available Acura NSX products are modern radial tires in the listed sizes, which makes them fundamentally more suitable for real road use than antique or display-only construction would be. Safety still depends on using the exact front and rear sizes required for the correct year range, mounting them on the proper rim diameters, and ensuring the tires are in sound condition. A modern radial in the wrong Acura NSX size is still the wrong tire.

Public-road use begins with fitment accuracy and condition, not just brand name or tread pattern. Check inflation, age, sidewall condition, and any signs of prior damage before driving. Because Acura NSX is a high-performance platform with staggered sizing, a mismatch between front and rear tires can affect steering response and stability more noticeably than it would on an ordinary passenger car.

Before driving an Acura NSX, inspect tire pressure, visible tread and sidewall condition, wheel integrity, and the exact front-rear size pairing on the car. Confirm that the front and rear tires match the correct Acura NSX year group and that the wheel diameters correspond to those tire sizes. Also look for cuts, bulges, embedded debris, uneven wear, or signs that the car has been sitting long enough to develop flat spots.

That pre-drive check matters because Acura NSX fitment changed several times across the years and because staggered performance tires can hide problems until the car is underway. If the steering feels nervous, the rear feels unsettled, or the car tracks oddly, stop and inspect rather than assuming it is normal behavior. A short garage check is much easier than diagnosing a size or condition problem on the road.

A safe speed for an Acura NSX always depends on the exact tire fitted, its condition, inflation, and whether the size matches the proper front and rear application for that year. Several listed Acura NSX products include modern ZR-designated sizing and performance-oriented series, but the presence of a high-performance size marking does not override age, damage, or incorrect fitment. Tire condition remains the first limiter, especially on collector-driven first-generation cars.

The practical approach is to drive only within the limits of the tires actually mounted on the car, not the theoretical capability of the Acura NSX itself. If the tires are older, recently mounted after long storage, or unfamiliar in brand and series, begin with moderate speeds and reassess after inspection and break-in use. Predictable handling and condition verification matter more than chasing the car's headline performance.
