The 2005 Avanti Avanti carried the long-running Avanti name into the modern era with a low-production, specialty-car personality that stands apart from mainstream coupes and sedans. Its styling and collector appeal make tire choice part of both the car’s stance and its road manners. This model uses staggered radial fitment, with 255/45R17 on the front and 255/50R17 on the rear, both on 17-inch rims. Available choices include blackwall, redline, and raised white letter treatments across series from BFGoodrich, Nitto, and Pro-Trac. For an owner, the key is matching the front-to-rear setup correctly while choosing the appearance and tire character that best suits the car’s intended use.
Which Tire Size Is Right for The 2005 Avanti Avanti
The 2005 Avanti Avanti uses two primary tire sizes, and the difference is tied to position on the car rather than a simple one-size setup. Both are radial tires on 17-inch rims, but the front uses 255/45R17 while the rear uses 255/50R17. The first step is confirming that the car still has its proper staggered wheel and tire arrangement before comparing brands, sidewall styles, and tire series.
A 255/45R17 size uses a 255-millimeter nominal section width, a 45-series aspect ratio, radial construction, and a 17-inch rim. On the 2005 Avanti Avanti, this size serves the front position, making steering feel, appearance, and proper front-end clearance part of the selection process. Available choices include blackwall, redline, and RWL sidewall treatments, with options from BFGoodrich, Nitto, and Pro-Trac across g-Force Sport Comp 2, NT555 G2, and Street Pro III lines. This is the size to evaluate when the front of the car needs correct replacement fitment without disturbing the staggered setup.
A 255/50R17 size keeps the same 255-millimeter nominal section width and 17-inch rim diameter, but its 50-series profile is taller than the 255/45R17 used at the front. On the 2005 Avanti Avanti, this size belongs at the rear, where it helps preserve the intended front-to-rear tire relationship. Product choices include blackwall, redline, and RWL versions from Nitto and Pro-Trac, including NT555 G2 and Street Pro III offerings. This rear size should be chosen with attention to maintaining the proper staggered arrangement and confirming wheel width and overall rear clearance.
Fitment on the 2005 Avanti Avanti is straightforward once the tire position is identified, because the front and rear use different sizes. Checking whether the tire is for the front or rear matters more than comparing trim differences within the model line.

2005 Avanti Avanti Base Front
The 2005 Avanti Avanti Base Front uses a 255/45R17 radial tire on a 17-inch rim. Tire selection here centers on preserving the proper front fitment while choosing among available blackwall, redline, or RWL styles and the tire series that best suits the car’s look and use.
The 2005 Avanti Avanti Base Rear uses a 255/50R17 radial tire on a 17-inch rim. That makes rear tire selection a matter of keeping the correct staggered setup in place and then comparing sidewall treatment, tire series, and wheel-width compatibility within the available choices.
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.

Owners researching 2005 Avanti Avanti tires usually need to confirm the front and rear sizes first, then compare sidewall style, tire series, and wheel fitment. The questions below focus on staggered sizing, radial tire choices, appearance, and practical road-use checks.
Tire Size & Fitment
What tire size fits a 2005 Avanti Avanti?
The 2005 Avanti Avanti uses a staggered radial setup rather than one size at all four corners. The front uses 255/45R17, and the rear uses 255/50R17, with both sizes designed for 17-inch rims.
That means tire selection starts with position on the car. A front-to-rear mix-up can change the intended stance and fitment relationship, so it is worth confirming which wheel is being replaced and checking that the car still has the correct staggered arrangement if wheels or suspension have ever been changed.
What size rim does a 2005 Avanti Avanti use?
Both primary tire sizes for the 2005 Avanti Avanti are built around a 17-inch rim diameter. The front 255/45R17 and the rear 255/50R17 share that diameter, even though they use different aspect ratios.
Rim diameter is only one part of fitment, so it should be confirmed along with actual wheel width before choosing a tire. The available products show different wheel-width ranges by size, which matters on a staggered car because the front and rear wheels may not be identical even when the rim diameter is the same.
Why does the 2005 Avanti Avanti have more than one tire size?
The 2005 Avanti Avanti has more than one tire size because it uses a staggered setup, with 255/45R17 at the front and 255/50R17 at the rear. The two sizes share the same 17-inch rim diameter but differ in profile.
For the buyer, that means the first step is identifying whether the tire is for the front or rear axle. It also makes it important to inspect the car’s current wheel arrangement, since an aftermarket wheel package or previous replacement choice can blur the original front-to-rear distinction and affect which size should be matched.
Choosing the Right Tire
What should I consider when choosing a 255/45R17 or 255/50R17 tire for a 2005 Avanti Avanti?
Start with the correct position-specific size, since the 2005 Avanti Avanti uses 255/45R17 in front and 255/50R17 in the rear. After that, compare construction details, wheel-width compatibility, load figures where stated, and the overall presentation you want from the tire.
The available choices also vary by tire series and sidewall treatment, so the right pick depends on whether the goal is a straightforward blackwall performance look or a more distinctive redline or raised white letter appearance. Checking the actual wheel width on the car keeps the comparison practical rather than cosmetic only.
What sidewall styles are available for 2005 Avanti Avanti tires?
The available sidewall styles for the 2005 Avanti Avanti include blackwall, redline, and RWL, depending on size and product line. Blackwall options appear in both front and rear fitments, while Pro-Trac Street Pro III choices add redline and raised white letter versions.
Sidewall style changes the personality of the car even when the size stays the same. A blackwall keeps the presentation more understated and modern, while redline or RWL adds a more deliberate period-inspired accent, so the better choice often depends on whether the car leans toward custom appearance, street use, or collector-minded presentation.
What brands offer tires for the 2005 Avanti Avanti?
Tires for the 2005 Avanti Avanti are available from BFGoodrich, Nitto, and Pro-Trac in the applicable 17-inch sizes. BFGoodrich appears in the front 255/45R17 fitment, Nitto covers both front and rear sizes, and Pro-Trac offers both sizes in its Street Pro III series.
Brand choice should be considered alongside size, wheel-width compatibility, sidewall treatment, and the tire series itself. On this car, the selection process is less about choosing a brand in isolation and more about finding the combination that keeps the staggered setup correct while matching the look and road-use character you want.
Restoration & Appearance
Which tire should I choose for a period-style 2005 Avanti Avanti?
A period-style approach for a 2005 Avanti Avanti usually starts by keeping the correct staggered sizes in place: 255/45R17 front and 255/50R17 rear. From there, the strongest visual distinction comes from the sidewall treatment and tire series rather than from changing the basic fitment.
Pro-Trac Street Pro III options with redline or RWL sidewalls create a more expressive, collector-oriented look, while blackwall designs keep the presentation cleaner and more contemporary. Exact originality questions are best settled with vehicle-specific history or marque documentation, but staying with the proper front and rear sizing remains the sound starting point.
How does tire construction affect the appearance of a restored 2005 Avanti Avanti?
On the 2005 Avanti Avanti, construction is less of a visual dividing line than it would be on an older collector car because both primary fitments are radial. The appearance difference comes more from sidewall style, tread presentation, and the tire series chosen within the correct front and rear sizes.
That makes this car’s restoration-oriented tire decision more about presentation than about choosing between bias-ply and radial forms. A blackwall tire can keep the look restrained, while redline or raised white letter versions add more emphasis, all without changing the basic 17-inch staggered fitment that defines the car’s stance.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2005 Avanti Avanti?
Yes, modifications can affect tire fitment on a 2005 Avanti Avanti, especially because the car uses different front and rear sizes. Aftermarket wheels, suspension changes, lowering, or body modifications can alter clearance and may also change the wheel widths available for the original 255/45R17 and 255/50R17 setup.
A car that still wears 17-inch wheels may not automatically match the intended fitment if offset or width has changed. Measuring the actual wheels and checking steering travel, rear clearance, and tire-to-body space helps prevent choosing a tire that is correct in size code but mismatched to the car’s current configuration.
What should I inspect before driving a 2005 Avanti Avanti on new tires?
Before driving a 2005 Avanti Avanti on new tires, inspect the wheels for damage, confirm the correct front and rear sizes were mounted, and verify tire pressure once the tires are installed. It is also smart to look at valve stems, wheel fasteners, and general suspension condition before heading onto the road.
A short initial check of steering clearance and rear clearance can catch problems early on a staggered car. After the first drive, rechecking pressure and giving the tires a visual inspection for rubbing, uneven seating, or unexpected contact around the wheel openings helps confirm that the installation matches the vehicle’s actual setup.
How often should tires on a 2005 Avanti Avanti be inspected?
Tires on a 2005 Avanti Avanti should be inspected regularly, even if the car is driven only occasionally. Collector and specialty cars often spend long periods parked, which makes it important to watch for air loss, sidewall cracking, tread irregularities, cuts, bulges, and signs of age that may not show up through mileage alone.
A brief inspection before drives and a more careful check during routine maintenance is a practical habit. Because this Avanti uses a staggered setup, it also helps to verify that the front 255/45R17 and rear 255/50R17 remain in the proper positions and that storage conditions are not accelerating deterioration between outings.
