The 2006 Acura RSX sits at the end of Acura’s sporty front-wheel-drive hatchback coupe era, blending compact dimensions, sharp styling, and a driver-focused personality that still makes it a favorite with import enthusiasts. Tire fitment matters because the RSX uses three distinct radial sizes across Base and Type-S configurations: 205/55R16, 215/45R17, and 225/45R17. That means the first step is confirming both sub-model and wheel diameter before choosing a tire. From straightforward blackwall performance options to more appearance-driven selections such as wide whitewall, raised white letter, or redline treatments, the right choice depends on whether the goal is stock-type sizing, modified style, or road-use priorities.
Which Tire Size Is Right for The 2006 Acura RSX
The 2006 Acura RSX uses three primary tire sizes, and the correct one depends on the exact sub-model and wheel diameter. The Base model uses a 16-inch setup, while Type-S fitment moves to 17-inch tires in two different widths. Before choosing a tire, confirm whether the car is a Base or Type-S and verify the wheels actually on the car, especially if it has been modified over the years.
205/55R16 is a modern metric radial size in which 205 is the section width in millimeters, 55 is the aspect ratio, R identifies radial construction, and 16 is the rim diameter in inches. On the 2006 Acura RSX, this size belongs to the 16-inch wheel setup used on the Base model. Available choices include BFGoodrich, Michelin, and American Classic, with blackwall and wide whitewall sidewall treatments and several tire series. This size suits buyers who want to stay with the Base-model fitment while comparing appearance and product character within the correct dimensions.
215/45R17 is a metric radial size that uses a 215-millimeter section width, a 45-series profile, and a 17-inch rim diameter. For the 2006 Acura RSX, this size is part of the Type-S fitment and places the decision squarely around the correct 17-inch configuration. BFGoodrich offers this size across g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A lines, all in blackwall form. It is the right size to evaluate when the car is a Type-S running the narrower of the two 17-inch primary fitments.
225/45R17 is a metric radial size with a 225-millimeter section width, a 45-series profile, and a 17-inch wheel diameter. On the 2006 Acura RSX, this is also tied to Type-S fitment, so it should not be treated as a universal RSX size. Product choice is broader here, with BFGoodrich, Nitto, and Pro-Trac options plus blackwall, raised white letter, and redline sidewall treatments across several series. This size deserves a closer look when the car has the wider 17-inch setup and the owner wants either a more traditional performance look or a custom appearance.
Sub-model fitment is not the same across the 2006 Acura RSX range. The Base model stays with one 16-inch tire size, while the Type-S uses 17-inch fitments, so confirming the exact sub-model is the key first step before comparing products.

2006 Acura RSX Base
The 2006 Acura RSX Base uses the 205/55R16 radial size on a 16-inch wheel setup. Tire selection is more about choosing among available brands, series, and sidewall presentation than sorting through multiple primary fitments.
The 2006 Acura RSX Type-S uses two 17-inch radial sizes, 215/45R17 and 225/45R17, so wheel confirmation matters before making a selection. That opens the door to comparing width, tire series, and appearance options within the Type-S fitment range rather than assuming every 17-inch RSX setup is the same.
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.

Buyers can compare blackwall, wide whitewall, raised white letter, and redline presentations across several radial tire series, with rim-width compatibility varying by size.
Common 2006 Acura RSX tire questions usually come down to sub-model fitment, 16-inch versus 17-inch wheels, and choosing the right radial tire within the correct size. Appearance, product variety, and checking a modified car before installation also matter.
Tire Size & Fitment
What tire size fits a 2006 Acura RSX?
A 2006 Acura RSX uses one of three radial tire sizes: 205/55R16, 215/45R17, or 225/45R17. The Base model uses 205/55R16, while the Type-S uses 215/45R17 or 225/45R17 depending on the exact wheel setup.
The practical step is to confirm both the sub-model and the wheel diameter on the car before choosing a tire. Many RSX cars have been changed over time, so the tire sidewall and the wheel itself should match the intended fitment rather than relying only on model name or appearance.
What size rim does a 2006 Acura RSX use?
The 2006 Acura RSX uses either a 16-inch or 17-inch rim, depending on configuration. The Base model pairs with 205/55R16, while Type-S fitment uses 17-inch sizes: 215/45R17 and 225/45R17.
Rim diameter is the first detail to verify because a 16-inch tire and a 17-inch tire are not interchangeable. Wheel width also matters once the diameter is confirmed, especially on the 17-inch Type-S sizes where product rim-width recommendations can vary from one tire line to another.
Why does the 2006 Acura RSX have more than one tire size?
The 2006 Acura RSX has more than one tire size because fitment differs between the Base and Type-S sub-models, and the Type-S itself uses two 17-inch primary sizes. That creates three correct radial sizes across the full model range.
This means tire selection starts with identifying the exact RSX configuration rather than picking by year and model alone. On a car that has seen wheel swaps or suspension changes, the safest approach is to confirm the current wheel diameter and installed size before comparing brands, series, or sidewall styles.
Choosing the Right Tire
What should I consider when choosing a 2006 Acura RSX tire?
Start with the correct primary size for the exact car: 205/55R16 for the Base model, or 215/45R17 or 225/45R17 for a Type-S. From there, compare radial construction details such as rim-width suitability, tire series, load figures where stated, and the type of driving the car actually sees.
Appearance can matter just as much as specifications on an RSX. Some owners want a straightforward blackwall performance look, while others may prefer a more custom presentation such as wide whitewall, raised white letter, or redline, provided that style is available in the correct size.
What sidewall styles are available for 2006 Acura RSX tires?
Sidewall choices for the 2006 Acura RSX include blackwall across all three primary sizes, a wide whitewall option in 205/55R16, and raised white letter and redline treatments in 225/45R17. Those appearance differences are tied to specific sizes and product lines rather than the full RSX range.
That makes sidewall style a secondary decision after fitment is confirmed. A Base model owner looking at 205/55R16 has different appearance options than a Type-S owner using 225/45R17, so the visual goal should be matched to the correct size before comparing the rest of the tire specifications.
What brands offer tires for the 2006 Acura RSX?
Tires for the 2006 Acura RSX are available from BFGoodrich, Michelin, American Classic, Nitto, and Pro-Trac. Brand coverage depends on size, with BFGoodrich appearing across all three primary fitments and other brands showing up in more size-specific roles.
Brand choice should be weighed alongside the exact tire series, sidewall style, and wheel setup rather than treated as a stand-alone answer. A buyer comparing 205/55R16 has a different product mix than someone shopping 225/45R17, so size confirmation still comes first before narrowing the field.
Restoration & Appearance
Which tire should I choose for a period-style 2006 Acura RSX?
A period-style 2006 Acura RSX tire choice starts with the correct size for the sub-model and wheel diameter already on the car. Blackwall radial tires keep the most familiar early-2000s sport-compact presentation, while 205/55R16 and 225/45R17 also open the door to more appearance-driven alternatives.
The right direction depends on whether the goal is an OEM-inspired look, a clean custom build, or a tuner-era visual style. Keeping the correct overall fitment matters more than chasing a theme, especially on a car where aftermarket wheels, ride height changes, or previous modifications may already affect the stance.
How does tire construction affect the appearance of a restored 2006 Acura RSX?
All primary 2006 Acura RSX fitments here are radial, so the appearance differences come less from construction type and more from the specific tire line and sidewall treatment. Blackwall is the mainstream look, while wide whitewall, raised white letter, and redline choices create a more custom visual statement in certain sizes.
That means appearance planning should focus on the exact size and the style that suits the build. A restoration-minded owner may want a restrained, era-appropriate presentation, while a custom RSX can lean harder into sidewall detail, provided the tire still matches the car’s wheel diameter and intended setup.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Acura RSX?
Yes, modifications can affect tire fitment on a 2006 Acura RSX. Aftermarket wheels, suspension changes, lowering, alignment changes, and body modifications can all alter the space available for a 205/55R16, 215/45R17, or 225/45R17 tire.
A modified RSX should be checked for actual wheel diameter, wheel width, and clearance at the fender, strut, and steering range before a new tire is chosen. Even when the size is correct for the model on paper, the car’s current setup determines whether that tire remains a sensible match.
What should I inspect before driving a 2006 Acura RSX on new tires?
Before driving a 2006 Acura RSX on new tires, inspect wheel condition, valve stems, inflation pressure, and lug torque, and make sure the installed size matches the wheel diameter. It is also worth checking for uneven wear patterns that could point to alignment or suspension issues.
A short initial road test can reveal rubbing, vibration, or steering pull that needs attention before regular use. Tire choice alone does not solve worn suspension parts or wheel damage, so confirming the overall condition of the car helps the new tires deliver the fitment and road manners expected.
How often should tires on a 2006 Acura RSX be inspected?
Tires on a 2006 Acura RSX should be inspected regularly, especially if the car is driven seasonally, stored for long periods, or used enthusiastically. Pressure loss, irregular tread wear, sidewall cracking, cuts, and bulges are all signs that deserve attention before normal road use.
Frequent inspection matters on cars that may have older wheels, modified suspension, or staggered replacement history. Looking over the tires before longer drives and during routine maintenance helps catch problems early, and it also confirms that the tire still suits the car’s present alignment, wheel setup, and clearance.
