The 2006 Subaru Impreza sits in a sweet spot for buyers who want compact all-wheel-drive practicality with distinct performance branches inside the same model line. In this model year, the range stretches from everyday 2.5i and Outback Sport trims to turbocharged WRX variants and the more aggressive WRX STI, so tire fitment starts with identifying the exact sub-model. Tire sizes span 205/55R16, 215/45R17, and 225/45R17, all in radial construction. Available choices then branch into different tire series, blackwall styles, and, in one fitment, specialty sidewall treatments such as raised white letter, redline, and wide whitewall. The right selection comes down to matching size, wheel diameter, intended appearance, and how the car is actually driven.
Which Tire Size Is Right for The 2006 Subaru Impreza
The 2006 Subaru Impreza uses three primary tire sizes, and they are tied directly to sub-model and wheel diameter. Two sizes use 17-inch rims while one uses a 16-inch rim, so the first step is confirming the exact sub-model and checking the wheel size currently on the car before comparing tire series, sidewall style, or other product details.
205/55R16 is a metric radial size in which 205 is the section width in millimeters, 55 is the aspect ratio, R designates radial construction, and 16 is the rim diameter in inches. On the 2006 Subaru Impreza, this size supports the more everyday side of the range and keeps the fitment centered on a 16-inch wheel. Product choices include BFGoodrich, Michelin, and American Classic options, with blackwall and wide whitewall sidewall treatments available. This size is the one to evaluate when maintaining stock wheel diameter on the sub-models that use it while still choosing between modern performance character and a more distinctive appearance.
215/45R17 is a metric radial size with a 215-millimeter nominal section width, a 45-series profile, and a 17-inch rim diameter. For the 2006 Subaru Impreza sub-models that use it, this fitment moves to a lower-profile 17-inch setup, making wheel confirmation more important before ordering. Available tires in this size come from BFGoodrich across the g-Force Comp 2 AS, g-Force Sport Comp 2, and g-Force Phenom T/A series, all in blackwall form. This is the size to focus on when the car is one of the WRX-family trims that carries the 17-inch configuration rather than the 16-inch setup.
225/45R17 is a metric radial size where 225 indicates nominal section width in millimeters, 45 is the aspect ratio, and 17 is the wheel diameter in inches. On the 2006 Subaru Impreza, this is the widest of the primary fitments shown here and it remains tied to a 17-inch wheel. Product selection is broader in this size, including BFGoodrich, Nitto, and Pro-Trac choices, with blackwall, raised white letter, and redline sidewall presentations. This size deserves a close look when the goal is to stay with the correct primary fitment for the sub-model that uses it while also comparing appearance and tire-series differences.
Sub-model fitment matters on the 2006 Subaru Impreza because tire size changes across the range. The 2.5i and Outback Sport share one size, the WRX family uses another, and the WRX STI moves to a different 17-inch fitment, so identifying the exact trim is the first step before comparing tire choices.

2006 Subaru Impreza 2.5i
The 2006 Subaru Impreza 2.5i uses the 205/55R16 radial size. That makes tire selection less about sorting through multiple primary fitments and more about choosing the right 16-inch product based on brand, intended use, and whether a traditional blackwall or a more distinctive sidewall style suits the car.
The 2006 Subaru Impreza Outback Sport also uses the 205/55R16 radial size. With fitment shared with the 2.5i, the main decision becomes selecting among the available 16-inch tire series and sidewall treatments while making sure the car still wears the correct wheel diameter.
The 2006 Subaru Impreza WRX uses the 215/45R17 radial size. Tire selection here starts with confirming the 17-inch wheel setup, then comparing the available BFGoodrich performance-oriented series within that exact fitment.
The 2006 Subaru Impreza WRX Limited uses the same 215/45R17 radial fitment as the standard WRX. That keeps the search focused on 17-inch tires in the correct size, with the choice coming down to tire series and the kind of driving the car sees.
The 2006 Subaru Impreza WRX STI uses 225/45R17 radial tires. This sub-model calls for checking the 17-inch wheel setup first, then comparing the broader mix of available brands and sidewall presentations offered in that size.
The 2006 Subaru Impreza WRX TR uses the 215/45R17 radial size. That places it with the same basic fitment family as other WRX variants, so the key decision is choosing the right 17-inch tire series rather than sorting through multiple primary sizes.
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 questions for a 2006 Subaru Impreza usually come down to exact sub-model fitment, 16-inch versus 17-inch wheels, and how to compare the available radial tire choices by series, sidewall style, and intended use.
Tire Size & Fitment
What tire size fits a 2006 Subaru Impreza?
A 2006 Subaru Impreza uses one of three primary tire sizes: 205/55R16, 215/45R17, or 225/45R17. The 2.5i and Outback Sport use 205/55R16, the WRX, WRX Limited, and WRX TR use 215/45R17, and the WRX STI uses 225/45R17.
That means there is no single tire size for every 2006 Impreza. Start by confirming the exact sub-model, then verify whether the car currently has 16-inch or 17-inch wheels, especially if it has seen wheel or suspension changes over the years.
What size rim does a 2006 Subaru Impreza use?
A 2006 Subaru Impreza uses either a 16-inch or 17-inch rim, depending on sub-model. The 205/55R16 fitment uses a 16-inch rim, while both 215/45R17 and 225/45R17 use 17-inch rims.
Wheel diameter is the first thing to verify before choosing a tire, because a 16-inch tire and a 17-inch tire are not interchangeable. If the car has aftermarket wheels, confirm the actual wheel diameter and width on the vehicle rather than relying only on model name.
Do all 2006 Subaru Impreza sub-models use the same tire size?
No, 2006 Subaru Impreza sub-models do not all use the same tire size. The 2.5i and Outback Sport share 205/55R16, the WRX family uses 215/45R17, and the WRX STI moves to 225/45R17.
That size split matters because it changes both tire dimensions and wheel diameter across the model range. A buyer who starts with the correct sub-model can compare tires confidently, while starting with the wrong trim can lead to looking at the wrong size and wheel setup.
Choosing the Right Tire
What should I consider when choosing a tire for a 2006 Subaru Impreza?
Start with the correct primary size for the exact 2006 Subaru Impreza sub-model, since this model line uses 205/55R16, 215/45R17, and 225/45R17 depending on trim. After size is confirmed, compare construction details, rim-width compatibility, tire series, load figures where stated, and the type of use the car sees.
A 2.5i or Outback Sport owner may focus on 16-inch versatility and appearance choices, while WRX and WRX STI owners may be comparing 17-inch performance-oriented options. Matching the tire to the wheel setup and the car’s real use is more important than choosing by brand name alone.
What sidewall styles are available for 2006 Subaru Impreza tires?
Sidewall styles for 2006 Subaru Impreza tires include blackwall, wide whitewall, raised white letter, and redline, depending on the tire size. Blackwall appears across all three primary sizes, wide whitewall appears in 205/55R16, and raised white letter and redline appear in 225/45R17.
The practical choice depends on whether the goal is a modern understated look or a more distinctive presentation. Sidewall style should always come after confirming the correct size, since not every appearance option is offered across every Impreza fitment.
What brands offer tires for the 2006 Subaru Impreza?
Tires for the 2006 Subaru Impreza are available from BFGoodrich, Michelin, American Classic, Nitto, and Pro-Trac. BFGoodrich appears across all three primary sizes, while the other brands show up in specific fitments rather than across the entire model range.
Brand is only one part of the decision. It still helps to compare tire series, sidewall treatment, and rim-width specifications within the correct size, because the available options differ noticeably between the 16-inch and 17-inch Impreza fitments.
Restoration & Appearance
Which tire should I choose for a period-style 2006 Subaru Impreza?
A period-style 2006 Subaru Impreza starts with the correct original fitment family for the exact sub-model, whether that is 205/55R16, 215/45R17, or 225/45R17. From there, the appearance decision depends on whether the car should present with a straightforward blackwall look or a more distinctive sidewall treatment where available.
For a stock-appearing driver, matching the proper size and wheel diameter usually matters more than chasing novelty. Owners who want a highly exact restoration standard should also compare surviving reference photos, original literature, or marque-specific guidance before settling on a particular sidewall presentation.
How does tire construction affect the appearance of a restored 2006 Subaru Impreza?
On a 2006 Subaru Impreza, construction does not create a bias-ply-versus-radial decision because the primary fitments are already radial. Appearance is shaped more by sidewall treatment and tire series than by switching between fundamentally different construction types.
That makes size accuracy and visual presentation the real priorities for a restoration-minded owner. A blackwall tire keeps the look closer to mainstream late-model practice, while wide whitewall, redline, or raised white letter options create a more customized impression in the sizes that offer them.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Subaru Impreza?
Yes, modifications can affect tire fitment on a 2006 Subaru Impreza even when the tire size itself is correct for the sub-model. Aftermarket wheels, different wheel widths, suspension changes, and ride-height changes can all alter clearance at the fender, strut, and steering range.
A car that no longer has its original wheel setup should be measured at the vehicle before choosing tires. Confirm wheel diameter first, then verify width and available clearance so the selected 205/55R16, 215/45R17, or 225/45R17 tire matches the car as it sits today.
What should I inspect before driving a 2006 Subaru Impreza on new tires?
Before driving a 2006 Subaru Impreza on new tires, inspect wheel condition, valve stems, tire pressure, and the general state of the suspension and alignment-related wear points. The tire should also match the correct wheel diameter and the intended sub-model fitment before the car goes back into normal use.
After installation, turn the steering from lock to lock and look for any contact issues, especially if the car has non-stock wheels or ride height. It also helps to recheck pressure and lug torque after initial driving so the new tires begin service on a stable setup.
How often should tires on a 2006 Subaru Impreza be inspected?
Tires on a 2006 Subaru Impreza should be inspected regularly for air loss, uneven tread wear, cuts, cracking, and bulges. Cars that see seasonal use or sit for long periods deserve extra attention, since age and storage conditions can matter almost as much as mileage.
A quick visual check before routine driving is smart, and a closer inspection before longer trips is even better. Owners should also keep an eye on wear patterns that may point to alignment, wheel, or suspension issues, especially on performance-oriented WRX and WRX STI setups.
