The 2003 Acura NSX sits in the final stretch of Honda’s aluminum-bodied supercar era, blending exotic proportions with the precision and usability that made the NSX such a standout among modern performance cars. By this point, the car’s tire fitment was firmly part of its handling balance, with a staggered radial setup using 215/40R17 up front and 255/40R17 at the rear on 17-inch wheels. That makes the real decision less about finding a random 17-inch tire and more about matching the front and rear sizes correctly while comparing available brands and tire series. For an NSX, tire choice needs to respect both the car’s appearance and the sharp road manners it was designed to deliver.
Which Tire Size Is Right for The 2003 Acura NSX
The 2003 Acura NSX uses two primary tire sizes, both in radial construction and both built for 17-inch wheels. The key is recognizing that this is a staggered setup, with one size assigned to the front and a larger size assigned to the rear, so the first step is confirming wheel position before selecting a tire.
215/40R17 is a metric radial size in which 215 indicates nominal section width in millimeters, 40 is the aspect ratio, R identifies radial construction, and 17 is the wheel diameter in inches. On the 2003 Acura NSX, this size serves the front position and plays a direct role in steering response and overall balance. It uses a lower-profile modern performance format rather than an older bias-ply or alphanumeric system. Selecting this size means staying with the correct front fitment and then verifying that the exact tire chosen matches the wheel and intended use of the car.
255/40R17 is a metric radial size with a 255-millimeter nominal section width, a 40-series aspect ratio, radial construction, and a 17-inch rim diameter. On the 2003 Acura NSX, this is the rear tire size, giving the car the wider rear footprint expected from a staggered performance setup. Available choices in this size include BFGoodrich, Nitto, and Vredestein, all in blackwall form and spread across several performance-oriented tire series. Choosing among them comes down to keeping the correct rear size while comparing rim-width compatibility, load figures where stated, and the character of each tire line.
Tire fitment on the 2003 Acura NSX is straightforward once wheel position is clear, because the covered NSX-T setup uses one dedicated front size and one dedicated rear size. Checking the exact front-versus-rear application matters more than choosing among multiple trim-specific combinations.

2003 Acura NSX T Front
The 2003 Acura NSX T Front uses a 215/40R17 radial tire on a 17-inch wheel. That makes the front tire decision one of maintaining the proper staggered fitment and selecting a tire that suits the car’s steering feel and intended road use.
The 2003 Acura NSX T Rear uses a 255/40R17 radial tire on a 17-inch wheel. Tire selection at the rear centers on preserving the correct staggered setup while comparing available blackwall performance tires by brand, series, and wheel-width compatibility.
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 2003 Acura NSX Tires for Sale
Available 255/40R17 options for the 2003 Acura NSX include BFGoodrich, Nitto, and Vredestein choices, all in blackwall radial construction. The main differences in the product grid come from tire series, stated load figures where given, and rim-width compatibility within the 17-inch rear fitment.
Owners researching 2003 Acura NSX tires usually need to confirm the staggered front and rear sizes first, then compare radial fitment, wheel compatibility, and available performance-oriented product choices. The questions below focus on those exact decisions.
Tire Size & Fitment
What tire size fits a 2003 Acura NSX?
The 2003 Acura NSX uses a staggered radial tire setup with 215/40R17 at the front and 255/40R17 at the rear. Both sizes mount on 17-inch wheels, but they are not the same size at all four corners, so front and rear position matters from the start.
That means the first check is not just wheel diameter, but also whether the tire is intended for the front or rear of the car. If the NSX has aftermarket wheels or a changed suspension setup, compare the actual wheel dimensions and available clearance before choosing replacements.
What size rim does a 2003 Acura NSX use?
The primary tire fitment for the 2003 Acura NSX uses 17-inch rims at both the front and rear. The front tire size is 215/40R17 and the rear tire size is 255/40R17, so the wheel diameter is shared even though the tire widths differ.
Matching the 17-inch diameter is only part of the process, because wheel width still affects which tires are suitable. A replacement tire should be checked against the actual wheel on the car, especially if the NSX no longer has its original wheel setup or has been modified over time.
What does 215/40R17 mean on a 2003 Acura NSX?
On a 2003 Acura NSX, 215/40R17 is the front tire size in a modern metric radial format. The 215 refers to nominal section width in millimeters, 40 is the aspect ratio, R means radial construction, and 17 identifies the wheel diameter in inches.
Understanding the code helps separate correct fitment from any random 17-inch tire. A tire with the same wheel diameter but a different width or profile can change how the car sits and clears the body, so the full size designation matters, not just the final number.
Choosing the Right Tire
What should I consider when choosing a 255/40R17 tire for a 2003 Acura NSX?
Start with the fact that 255/40R17 is the rear tire size for the 2003 Acura NSX, so the tire needs to suit the rear position in a staggered setup. Available choices include blackwall radial tires from BFGoodrich, Nitto, and Vredestein across several different performance-oriented tire series.
The useful comparisons are rim-width compatibility, load figures where they are stated, and the overall character of the tire line rather than brand ranking. A rear tire should also be matched sensibly to the front fitment so the NSX keeps the balanced look and handling expected from its original sizing layout.
What sidewall styles are available for 2003 Acura NSX tires?
The available 255/40R17 products for the 2003 Acura NSX use a blackwall sidewall style. That keeps the presentation clean and modern, which suits the NSX’s later-model performance appearance more naturally than a vintage-style whitewall or striped treatment.
Sidewall appearance does not replace the need to confirm the correct size and wheel fitment, but it does shape how the car looks once mounted. For an NSX owner comparing rear tire options, the bigger visual differences come from tire profile and tread design rather than decorative sidewall treatments.
What brands offer tires for the 2003 Acura NSX?
The 255/40R17 rear fitment for the 2003 Acura NSX is available from BFGoodrich, Nitto, and Vredestein. Those brands cover several distinct tire series, including g-Force Sport Comp 2, g-Force Comp 2 AS, Nitto NT555 G2, and Sprint Plus.
Brand alone should not drive the decision on a staggered performance car. It is smarter to compare the exact tire series, check the wheel-width specification, and make sure the chosen rear tire works cleanly with the NSX’s front-and-rear sizing relationship and the way the car is actually used.
Restoration & Appearance
Does correct tire fitment matter for a 2003 Acura NSX restoration?
Correct tire fitment matters on a 2003 Acura NSX restoration because the car uses a specific staggered arrangement rather than one universal size. Keeping the proper 215/40R17 front and 255/40R17 rear relationship preserves the visual stance and supports the handling balance associated with the model.
Appearance and function work together on a car like the NSX, so wheel position and tire proportion should be treated carefully. If exact historical presentation is part of the goal, it also helps to compare the finished look of the tire on the car rather than choosing only by brand name.
How does tire construction affect the appearance of a restored 2003 Acura NSX?
The 2003 Acura NSX uses radial tire fitment, so the restored appearance should still center on a modern low-profile radial look rather than a vintage bias-ply presentation. The 215/40R17 front and 255/40R17 rear sizes contribute to the car’s later-era supercar stance and should remain part of the visual plan.
Because the available rear products are blackwall tires, the appearance differences come more from tire shape and series character than from decorative sidewall styling. A restoration-minded owner should make sure the front and rear tires complement each other visually and maintain the correct staggered proportions on the car.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2003 Acura NSX?
Yes, modifications can affect tire fitment on a 2003 Acura NSX even when the original tire sizes are known. Changes such as aftermarket wheels, altered wheel width, suspension lowering, or alignment adjustments can influence how a 215/40R17 front or 255/40R17 rear tire sits in the car.
The safest approach is to confirm the actual wheel dimensions and inspect steering, fender, and suspension clearance before replacing tires. A staggered car can be especially sensitive to setup changes, so the front and rear positions should each be checked rather than assuming the stock-size label tells the whole story.
What should I inspect before driving a 2003 Acura NSX on new tires?
Before driving a 2003 Acura NSX on new tires, inspect the wheel condition, confirm that the front and rear tires are mounted in the correct positions, and check inflation pressure carefully. It also helps to look over the suspension and alignment condition so the new tires start with a sound mechanical foundation.
A short road test should be used to watch for rubbing, vibration, or any sign that the tire is not seating or clearing as expected. On a low-profile staggered setup, even small issues can be noticeable, so catching them early helps protect both the tire and the car.
What should I check before a longer drive in a 2003 Acura NSX?
Before a longer drive in a 2003 Acura NSX, check tire pressure, tread condition, sidewall condition, and any sign of cuts, bulges, or air loss. It is also worth confirming that the 215/40R17 front and 255/40R17 rear sizes remain correctly installed, especially if the tires have recently been serviced or rotated side to side.
Collector and low-use cars can develop issues even when they do not see many miles, so age and storage condition matter as much as tread depth. A quick clearance and visual inspection around the wheel wells can also help catch problems before they become more serious on the road.
