The 2005 Acura RSX sits in the final chapter of Acura’s compact sport coupe line, combining front-wheel-drive practicality with a distinctly tuner-era personality that still appeals to drivers who value sharp handling and clean styling. Tire choice matters more here than it does on many older collector cars because the RSX’s stance, steering response, and ride balance are closely tied to its wheel-and-tire package. The 2005 Acura RSX uses two primary radial tire sizes, with 205/55R16 for the Base and 215/45R17 for the Type-S. Available choices range from performance-focused blackwall radials to a wide whitewall option in 205/55R16. The right selection starts with confirming the sub-model and wheel diameter, then matching the tire’s character to the car’s intended use.
Which Tire Size Is Right for The 2005 Acura RSX
The 2005 Acura RSX uses two primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. The Base uses a 16-inch radial fitment, while the Type-S uses a 17-inch radial fitment, so identifying the car first and confirming the wheel size should happen before comparing brands, series, or sidewall style.
205/55R16 is a modern metric radial size in which 205 identifies the nominal section width in millimeters, 55 is the aspect ratio, R indicates radial construction, and 16 is the rim diameter in inches. On the 2005 Acura RSX, this size belongs to the Base model and keeps the fitment centered around a 16-inch wheel. Product choices include BFGoodrich, Michelin, and American Classic, with blackwall and wide whitewall sidewall treatments available across several tire series. This size is the right place to focus if the car carries the Base-model wheel package or if appearance and ride character need to stay aligned with that setup.
215/45R17 is a modern metric radial size with a 215-millimeter nominal section width, a 45-series aspect ratio, radial construction, and a 17-inch rim diameter. On the 2005 Acura RSX, this size is used on the Type-S and reflects a lower-profile wheel-and-tire package than the Base model. Available options in this size center on BFGoodrich performance-oriented series, all in blackwall form. This is the size to evaluate when the car is a Type-S or when the wheel setup is already confirmed as the factory-style 17-inch configuration.
Sub-model fitment matters on the 2005 Acura RSX because the Base and Type-S do not use the same tire size or the same rim diameter. Selecting tires starts with identifying which version of the RSX is in the garage and confirming whether it still has the correct wheel setup.

2005 Acura RSX Base
The 2005 Acura RSX Base uses a 205/55R16 radial tire on a 16-inch wheel package. That makes tire selection more about choosing among available brands, series, and sidewall treatments than sorting through multiple fitment sizes.
The 2005 Acura RSX Type-S uses a 215/45R17 radial tire on a 17-inch wheel package. Tire selection here should begin with confirming the 17-inch setup, then comparing the available performance-oriented options within that exact size.
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 2005 Acura RSX?
The 2005 Acura RSX uses two tire sizes, depending on sub-model. The Base uses 205/55R16, while the Type-S uses 215/45R17. Both are radial fitments, but they are tied to different wheel diameters, so they are not just alternate sizes for the same setup.
The first step is identifying whether the car is a Base or a Type-S, then confirming the wheel diameter currently on the vehicle. A used RSX may have aftermarket wheels or a mixed set from a previous owner, so the safest path is matching the tire size to the actual wheel and the correct sub-model.
What size rim does a 2005 Acura RSX use?
A 2005 Acura RSX uses either a 16-inch or 17-inch rim, depending on sub-model. The Base pairs with a 16-inch wheel and 205/55R16 tires, while the Type-S pairs with a 17-inch wheel and 215/45R17 tires. Both fitments use radial construction.
Rim diameter should be confirmed before any tire purchase because the two RSX sizes are built around different wheels. It is also smart to check wheel width if the car has been changed from stock, since available tires in these sizes carry their own approved rim-width ranges that affect proper mounting and tire shape.
Do all 2005 Acura RSX sub-models use the same tire size?
No. The 2005 Acura RSX Base uses 205/55R16, and the 2005 Acura RSX Type-S uses 215/45R17. Both are modern radial sizes, but they belong to different sub-models and different wheel diameters, so the fitment is not shared across the full RSX range.
That difference matters because the wrong size can create an immediate mismatch with the wheel even before clearance or handling are considered. Anyone replacing tires on an RSX with unknown history should verify the sub-model, measure the wheel diameter, and make sure the car has not been converted to a different wheel-and-tire package over time.
Choosing the Right Tire
What should I consider when choosing a 2005 Acura RSX tire?
Start with the correct size for the sub-model: 205/55R16 for the Base or 215/45R17 for the Type-S. From there, compare construction, approved rim-width range, sidewall style, tire series, and any load information that matters for the way the car is driven and maintained.
A Base owner may be deciding between a performance blackwall radial and a more appearance-driven wide whitewall option, while a Type-S owner will be comparing blackwall performance-oriented choices within 215/45R17. Matching the tire’s character to the car’s use, while keeping wheel compatibility in view, usually leads to a better result than focusing on brand name alone.
What sidewall styles are available for 2005 Acura RSX tires?
Sidewall style depends on size. In 205/55R16, the 2005 Acura RSX has blackwall options along with a wide whitewall radial. In 215/45R17, the available choices are blackwall only. That means appearance flexibility is greater on the Base-model tire size than on the Type-S size.
Sidewall treatment changes the visual impression of the car even when the fitment stays correct. A blackwall keeps the look closer to a contemporary sport compact presentation, while a wide whitewall creates a more customized appearance. The best choice comes down to whether the goal is performance-oriented styling, a distinct visual statement, or a more unusual personalized finish.
What brands offer tires for the 2005 Acura RSX?
The 2005 Acura RSX is covered by BFGoodrich in both primary sizes, while Michelin and American Classic appear in 205/55R16. Within BFGoodrich, the available series include g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A, giving the RSX several radial options in the correct fitments.
Brand choice should still be filtered through the exact size and wheel package first. A Base owner has a broader mix of brands and appearance choices to compare, while a Type-S owner is really comparing BFGoodrich series within 215/45R17. Looking at series character, sidewall style, and rim-width compatibility usually tells more than the brand name by itself.
Restoration & Appearance
Which tire should I choose for a period-style 2005 Acura RSX?
A period-style 2005 Acura RSX starts with the correct sub-model fitment: 205/55R16 for the Base or 215/45R17 for the Type-S. Since this car comes from the modern sport-compact era, a blackwall radial usually preserves the cleanest time-appropriate look, especially on a car kept close to its original wheel presentation.
Appearance goals still vary. A Base owner can also consider the 205/55R16 wide whitewall option for a more customized interpretation, but that is a styling decision rather than a restoration-driven one. For buyers chasing exact historical authenticity, wheel design, ride height, and period photos of the specific car can matter just as much as the tire itself.
How does tire construction affect the appearance of a restored 2005 Acura RSX?
On a 2005 Acura RSX, construction does not create a bias-ply-versus-radial decision because the primary fitments are already radial. The visual difference comes more from the tire’s sidewall treatment, tread presentation, and overall profile within the correct size than from switching between two fundamentally different vintage constructions.
That makes size discipline especially important on an RSX restoration or cleanup project. Staying with 205/55R16 on the Base or 215/45R17 on the Type-S keeps the car closer to its intended stance, while the sidewall choice fine-tunes the look. A wide whitewall can dramatically change the Base model’s personality, whereas blackwalls keep the presentation more restrained and era-consistent.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2005 Acura RSX?
Yes. A 2005 Acura RSX may have aftermarket wheels, lowered suspension, altered alignment settings, or body changes that affect tire clearance and wheel compatibility. Those changes matter even when the tire size looks close on paper, because the Base and Type-S already start from different wheel diameters and fitment packages.
Checking the actual wheel diameter and width is the first step, followed by inspection of inner clearance, fender space, and steering travel. Cars with suspension changes deserve extra attention because a tire that suits one RSX setup may not suit another. That is especially important when replacing only two tires on a car with an unknown modification history.
What should I inspect before driving a 2005 Acura RSX on new tires?
Before driving a 2005 Acura RSX on new tires, inspect wheel condition, valve stems, lug hardware, and inflation pressure, then make sure the installed size matches the car’s Base or Type-S wheel package. A quick look at alignment wear points, brake clearance, and any rubbing marks is also worthwhile before regular road use begins.
The same inspection should include the suspension and steering basics, especially on a car that has seen hard use or modifications. Uneven ride height, loose components, or existing fender contact can shorten tire life quickly. After the first miles, rechecking pressure and watching for vibration or pull helps confirm that the installation and vehicle condition are working together properly.
How often should tires on a 2005 Acura RSX be inspected?
Tires on a 2005 Acura RSX should be inspected regularly, not just when tread looks low. Pressure, tread wear pattern, sidewall condition, and signs of puncture or impact damage deserve routine attention because compact sport coupes can be sensitive to tire condition, especially when running lower-profile fitments such as the Type-S 215/45R17 size.
Monthly visual checks are a sensible habit, with a closer inspection before longer trips or spirited seasonal use. Cars that sit for extended periods should also be checked for flat spotting, air loss, and age-related cracking. Any RSX with aftermarket wheels, lowered suspension, or aggressive alignment settings benefits from more frequent inspection because those changes can speed up wear.
