Avanti Avanti Tires

Avanti Avanti uses five tire sizes across the 2005 to 2007 model range. The listed sizes are 255/45R17 and 255/50R17 for 2005, 235/55R17 for 2006, and 245/40R18 plus 275/40R18 for 2007. The 2005 and 2006 applications use 17-inch rims, while the 2007 applications use 18-inch rims. All of the available products for these sizes are radial tires.

That means year alone is only part of the answer, especially for 2005 and 2007 where more than one size appears. Start by confirming the model year, then read the size molded on the tire sidewall and verify the wheel diameter on the car. If the car has been modified, the actual wheel and tire combination matters more than assumptions tied to the model year.

A 2005 Avanti Avanti can use either 255/45R17 or 255/50R17, and a 2007 Avanti Avanti can use either 245/40R18 or 275/40R18. In both years, the multiple listings reflect configuration differences rather than a single universal tire size for every car built that year. The 2007 pair also indicates different widths on the 18-inch setup, which is common when front and rear fitments are not identical.

The practical step is to identify the exact size currently fitted to the car and compare it with the wheel diameter before replacing anything. A buyer working from registration paperwork or memory alone can easily choose the wrong section width or sidewall profile. Checking both the wheel and the mounted tire is the safest way to match what the car actually uses.

Avanti Avanti uses two rim diameters across this model group: 17 inches and 18 inches. The 17-inch sizes are used in 2005 and 2006, while the 18-inch sizes appear in 2007. That year marks the wheel-diameter change within the production span covered here. Every listed tire size includes the rim diameter in the final number of the metric code.

Wheel diameter is the first fitment point to confirm because a 17-inch tire cannot be mounted on an 18-inch wheel, and the reverse is equally true. Once the wheel diameter is established, the remaining fitment decision comes down to the exact width and aspect ratio used on that specific car. This one check quickly narrows the options from five sizes to the correct group.

The correct way to confirm Avanti Avanti tire size is to match three things: the model year, the wheel diameter, and the size currently fitted to the car. A 2006 Avanti Avanti is straightforward because it uses 235/55R17, but 2005 and 2007 each have two listed sizes. On a metric radial, the last number gives wheel diameter, while the first two numbers define width and sidewall profile.

Read the sidewall on each tire and compare it to the wheel setup on the car rather than relying on a general year-based assumption. If the car has staggered or upgraded wheels, front and rear may not match in width. Original paperwork, prior service records, or a knowledgeable Avanti specialist can help if the car’s current fitment is in question.

Avanti Avanti tires are available in several sidewall styles across the listed sizes, including blackwall, redline, RWL, goldline, and wide whitewall. Blackwall appears across every size group, while redline and RWL are available on several of the 17-inch and 18-inch performance sizes. Goldline and wide whitewall choices appear in 235/55R17, giving the 2006 fitment a broader visual range than a typical modern-only performance application.

That sidewall variety lets an owner tune the car’s appearance toward a more understated modern performance look or toward a more nostalgic custom presentation. The key is to choose the sidewall style only after the actual size is settled, because appearance does not override fitment. On a low-production specialty car like Avanti Avanti, visual authenticity often depends on the owner’s restoration intent as much as model year.

Six brands appear in the available Avanti Avanti tire offerings: BFGoodrich, Nitto, Pro-Trac, American Classic, Coker Classic, and M&H Racemaster. BFGoodrich and Nitto cover several of the blackwall performance radial sizes, while Pro-Trac adds redline and RWL variations in multiple applications. American Classic and Coker Classic appear in the 235/55R17 fitment, and M&H Racemaster appears in 245/40R18.

Brand choice should follow the intended use of the car rather than brand recognition alone. A driver-oriented car may point toward one type of tread or sidewall, while a show-focused car may place more value on a specific visual treatment such as redline or whitewall. Once the correct size is established, the best brand choice is usually the one that matches how the Avanti Avanti will actually be used.

Avanti Avanti tire options include several series, among them g-Force Sport Comp 2, Nitto NT555 G2, Street Pro III, g-Force Comp 2 AS, g-Force Phenom T/A, Asymmetrical Tread, Star Series, and Drag Radial. These series represent different approaches within modern radial construction, from performance street applications to appearance-focused collector radials and a drag-oriented radial offering in one 18-inch size. The distinctions are tied more to tread design, intended use, and sidewall presentation than to basic fitment.

That means the right series depends on whether the Avanti Avanti is a road-driven specialty coupe, a custom-styled cruiser, or a car aimed at more focused straight-line use. Size remains the first filter, because not every series is offered in every fitment. Once size is confirmed, compare sidewall style, intended use, and wheel-width compatibility to narrow the most appropriate choice.

An Avanti Avanti should be stored in a cool, dry, dark space with the tires kept away from direct sunlight, ozone sources, and prolonged exposure to heat. Inflate the tires to an appropriate storage pressure for the fitted size and keep the car on a clean surface rather than bare earth. If the car will sit for long periods, rolling it periodically or supporting it properly can help reduce flat-spotting on modern radial tires.

Collector cars often spend more time parked than driven, and tire condition can deteriorate from age and storage stress even when tread still looks fresh. Checking pressure during storage matters because an underinflated parked car places unnecessary strain on the casing. A brief inspection before and after storage seasons helps catch sidewall cracking, pressure loss, or shape changes early.

Tires on an Avanti Avanti should be inspected before any meaningful road use and at regular intervals even when the car is driven only occasionally. Look for pressure loss, uneven wear, weather checking, sidewall cuts, punctures, and any signs that the tire is contacting suspension or bodywork. On staggered or multi-size setups, inspect each axle carefully because front and rear tires may age or wear differently.

A low-mile collector car can hide tire problems because time, storage, and heat cycles continue to affect the rubber even when the odometer barely changes. Frequent visual checks are especially important after seasonal storage or after the car has been parked for several weeks. Any vibration, pull, or sudden change in ride quality should prompt a closer inspection before further driving.

Avanti Avanti tires should be replaced when age, cracking, hardening, impact damage, repeated air loss, or structural irregularities appear, even if the tread depth still looks usable. Collector cars often reach the age-related replacement point long before they wear out the tread. A tire can look presentable from a few feet away and still be unsuitable for dependable road use once the casing and rubber have aged.

The practical rule is to treat calendar age and condition as seriously as tread depth, especially on a specialty car that sees intermittent use. If the tires have an uncertain service history, a thorough inspection by a tire professional familiar with older and performance applications is wise. Replacing aged tires proactively protects the wheels, the car, and the driving experience.

Avanti Avanti uses modern metric radial sizes in this 2005 to 2007 range, with 255/45R17 and 255/50R17 listed for 2005, 235/55R17 for 2006, and 245/40R18 plus 275/40R18 for 2007. Several radial series are available within those sizes, including performance street designs and collector-oriented sidewall treatments. Because more than one size appears in some years, there is not a single universal answer that applies to every Avanti Avanti in the range.

For an authenticity-minded owner, the most reliable path is to verify the car’s original wheel and tire package through surviving paperwork, period photos, or marque expertise. That matters most in 2005 and 2007, where multiple fitments appear within the same model year. Once the exact size is confirmed, the sidewall style can be chosen to match the intended period look of the individual car.

Correct tire fitment can affect both presentation and perceived authenticity on an Avanti Avanti, especially because wheel diameter, sidewall profile, and sidewall style noticeably shape the car’s stance. A car fitted with the wrong diameter, the wrong aspect ratio, or a visual treatment that clashes with the build can look out of character even if the tire physically mounts. On specialty collector cars, those details are often noticed quickly by experienced enthusiasts.

Owners who care about judging, resale presentation, or faithful restoration should match the tire size and appearance to the exact configuration of the car rather than choosing by general preference alone. Marque clubs, prior owner records, and period images are often the best references for how a specific Avanti Avanti was equipped. Small differences in sidewall treatment can change the overall impression more than many buyers expect.

Avanti Avanti tire offerings include blackwall, redline, RWL, goldline, and wide whitewall sidewall styles, but the most correct choice depends on the specific look being restored. Blackwall is the broadest and most consistently available style across the listed sizes, while redline and RWL introduce a stronger performance or custom appearance. Goldline and wide whitewall are available in 235/55R17, making that 2006 fitment especially flexible for a period-inspired visual approach.

A restoration aimed at factory-like presentation should prioritize the sidewall treatment that matches the car’s original delivery or long-established period character. A custom or personalized Avanti Avanti may reasonably lean toward redline, goldline, or whitewall if that supports the overall build theme. The key is to settle the correct tire size first, then choose the sidewall style that suits the restoration goal.

The available Avanti Avanti tires are modern radial products in the listed sizes, so they are suitable for public-road use when the size, wheel diameter, and overall condition are correct for the car. Safety depends on matching the tire to the actual rim size and intended application, then maintaining proper inflation and condition. A modern radial in good shape is a very different proposition from an aged or incorrectly fitted tire, even if both share the same basic dimensions.

Before regular road use, verify that all four tires are the correct sizes for their wheel positions and that there is no rubbing, impact damage, or age-related deterioration. Cars that have been stored, modified, or infrequently driven deserve an especially careful inspection. Public-road safety comes from the whole setup working together, not simply from having new tread.

Before driving an Avanti Avanti, check tire pressure, visible sidewall condition, tread condition, wheel security, and basic clearance around the tires. Confirm that the car is wearing the correct 17-inch or 18-inch tire group for its wheels and that multi-size setups are mounted in their proper positions. Also pay attention to any flat spotting, vibration, or steering pull if the car has been parked for a long time.

A specialty collector car can look ready to go while still hiding tire-related issues from storage or prior modifications. A short, low-speed shakedown drive after inspection is a sensible way to detect problems before committing to longer road use. If anything feels unusual, stop and inspect again rather than assuming the issue will clear up on its own.

An Avanti Avanti fitted with the correct modern radial size and a sound, properly maintained tire can be driven in a manner appropriate to current road conditions, but speed should always respect the tire’s condition, the car’s mechanical state, and the way the specific setup is intended to be used. Not every available series serves the same purpose, and a drag-oriented radial should not be treated exactly like an all-around street tire. The condition of the individual tire matters as much as the category.

For a collector-driven Avanti Avanti, smooth driving and conservative judgment are usually more important than exploring the upper edge of performance. A car that has sat for months, has uncertain alignment, or wears older tires should be driven more cautiously until everything is fully evaluated. Stability, steering feel, and temperature conditions should all inform how hard the car is used on the road.
