The 1985 Avanti II carried one of America’s most distinctive personal-luxury shapes into the later classic era, blending hand-built exclusivity with styling that still traces back to the original Avanti concept. By the mid-1980s, an Avanti buyer was usually looking for a car with individuality rather than mass-market sameness, and tire choice plays a big role in preserving that character. The 1985 Avanti II uses a 205/75R15 radial on a 15-inch rim. Within that size, there is real choice in whitewall widths, a goldline treatment, a redline option, and several radial series from brands such as BFGoodrich, American Classic, Coker Classic, Maxxis, Tornel, and Travelstar. The right selection depends on whether the priority is traditional appearance, road-going practicality, or a balanced restoration-oriented presentation.
Which Tire Size Is Right for The 1985 Avanti II
The 1985 Avanti II uses one primary tire size: 205/75R15, a radial fitment for a 15-inch rim. Both the Base and GT share that same size, so the main decision is not which primary size fits, but which version of 205/75R15 best suits the car’s appearance, intended road use, and wheel setup.
In 205/75R15, the 205 is the nominal section width in millimeters, 75 is the aspect ratio, R identifies radial construction, and 15 is the rim diameter in inches. For the 1985 Avanti II, this is the core fitment and it aligns with the car’s later-era radial-tire character rather than an earlier bias-ply presentation. Available choices within this size include wide whitewall, narrow whitewall, goldline, and redline styles across series such as Silvertown Radial, American Classic Radial, Coker Classic Radial, Star Series, Tornel Classic, Classic Whitewall MA-1, and UN106. That makes this size especially useful for owners who want to tune the car’s look without stepping away from the proper basic fitment.
Tire fitment is straightforward across the covered 1985 Avanti II sub-models because both use the same primary size. Checking the exact sub-model still helps confirm that the car remains on its intended 15-inch wheel setup before choosing among the available radial and sidewall options.

1985 Avanti II Base
The 1985 Avanti II Base uses the same 205/75R15 radial fitment as the rest of the model range. That keeps tire selection focused on appearance and product details, such as whitewall width or specialty sidewall treatment, rather than on navigating multiple primary sizes.
The 1985 Avanti II GT also uses 205/75R15 radial tires on a 15-inch rim. For a GT owner, the decision centers on choosing the right style within that size and confirming that any wheel or suspension changes have not altered the car’s original fitment needs.
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 1985 Avanti II?
The 1985 Avanti II uses a 205/75R15 radial tire. That is the primary fitment for the model and it applies across the covered Base and GT sub-models, both of which use the same 15-inch rim diameter.
That consistency makes size selection simple, but the next step still matters. An Avanti II owner should confirm that the car still has the correct wheel diameter and that no aftermarket wheel or suspension change has altered clearance before choosing among the available 205/75R15 radial options.
What size rim does a 1985 Avanti II use?
The 1985 Avanti II uses a 15-inch rim with its 205/75R15 tire size. The tire itself is built around that 15-inch wheel diameter, so confirming the wheel size is a basic first step before comparing whitewall, goldline, redline, or other product variations.
Rim diameter is only part of the picture. Several 205/75R15 products also carry rim-width guidance, commonly around 5 to 7 inches or 5.50 to 7.50 inches, so wheel width should be checked as well, especially if the car has replacement wheels or a modified stance.
Do all 1985 Avanti II sub-models use the same tire size?
Yes. Both the 1985 Avanti II Base and 1985 Avanti II GT use the same 205/75R15 radial tire size. There is no split in primary tire size between those covered sub-models, which simplifies fitment compared with vehicles that vary by trim or package.
Even with shared fitment, the tire decision is not automatic. Owners still need to choose the sidewall style and tire series that best suits the car, and it is wise to verify the actual wheel setup on any Avanti II that may have seen wheel swaps, suspension work, or long-term storage.
Choosing the Right Tire
What should I consider when choosing a 205/75R15 tire for a 1985 Avanti II?
Start with the correct 205/75R15 size and 15-inch rim compatibility, then look at the kind of presentation the car should have. For a 1985 Avanti II, the big decision inside this size is usually sidewall style and tire series rather than basic fitment, since all of the main options are radial.
From there, compare details such as whitewall width, goldline or redline treatment, rim-width guidance, and load figures where they are given. A car kept close to its period look may call for one appearance, while a more regularly driven Avanti II may lead the owner toward a different visual and specification balance.
What sidewall styles are available for 1985 Avanti II tires?
The 1985 Avanti II’s 205/75R15 tire choices include wide whitewall, narrow whitewall, goldline, and redline sidewall styles. Those options give the car a broad visual range, from a traditional personal-luxury look to a sportier period-style presentation.
Sidewall style changes the car’s character more than many owners expect, so it should be chosen with the overall build in mind. A restoration-oriented Avanti II may suit one whitewall width, while a car with a more customized or performance-inspired look may point toward goldline or redline instead.
What brands offer tires for the 1985 Avanti II?
The 1985 Avanti II’s 205/75R15 fitment is available from BFGoodrich, American Classic, Coker Classic, Tornel, Maxxis, and Travelstar. Those brands appear across several radial series, giving the owner more than one path to a suitable tire in the correct size.
Brand choice should be weighed alongside sidewall treatment, series character, and wheel compatibility rather than treated as a shortcut. Two tires may share the same 205/75R15 size but differ in rim-width guidance, load figures, weight, or styling details, all of which can influence the final decision.
Restoration & Appearance
Which tire should I choose for a period-style 1985 Avanti II?
A period-style 1985 Avanti II starts with the correct 205/75R15 radial size, then narrows the choice by visual character. Wide whitewall, narrow whitewall, goldline, and redline versions are all available, so the right tire depends on whether the car is being presented as elegant, sporty, or somewhere between.
For a restoration-oriented build, appearance should be weighed just as carefully as size and wheel fit. If exact originality matters, the safest approach is to compare the car against marque references, period photos, and other vehicle-specific historical material before settling on a sidewall treatment or tire series.
How does tire construction affect the appearance of a restored 1985 Avanti II?
On a 1985 Avanti II, construction is less about bias-ply versus radial debate and more about choosing the right radial presentation within the proper size. Since 205/75R15 is already a radial fitment, the visual difference comes mainly from sidewall style, whitewall width, and the tire series selected.
That means a restored car can keep its correct basic construction while still shifting its personality noticeably. A narrow whitewall may look restrained, a wide whitewall more formal, and a goldline or redline more assertive, so the tire should support the car’s trim, wheel design, and intended period impression.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1985 Avanti II?
Yes. Even though the 1985 Avanti II uses 205/75R15 on a 15-inch rim, wheel and suspension changes can affect how that size works on the car. Aftermarket wheels, altered wheel width, ride-height changes, and body or brake modifications can all change the clearance picture.
An owner should verify the actual wheel diameter and width already on the car, then check steering clearance, fender clearance, and suspension travel before installing new tires. That is especially important on a specialty car like an Avanti II, where appearance updates may have been made over time.
What should I inspect before driving a 1985 Avanti II on new tires?
Before road use, inspect the wheel condition, valve stems, lug hardware, and overall clearance around the 205/75R15 tires. It also makes sense to confirm inflation pressure, look for any interference at full steering lock, and make sure the suspension and steering components are in sound condition.
A collector-era car that has sat for long periods deserves extra attention. Check for old alignment issues, uneven wear from previous tires, and any signs that the car has settled or shifted during storage, since those details can affect how a fresh set of radials behaves once the Avanti II is back on the road.
How should 205/75R15 tires on a collector 1985 Avanti II be maintained?
Collector-car tire maintenance starts with regular pressure checks, visual inspection, and clean storage conditions. On a 1985 Avanti II, the 205/75R15 tires should be inspected for cracking, bulges, cuts, tread wear, and air loss even if the car sees only occasional mileage.
Low-use cars can age tires out long before they wear them out, so the tires should be checked before each driving season and again before any longer trip. Keeping the car away from prolonged sunlight, heat, moisture, and ozone sources helps preserve both the rubber and the sidewall appearance.
