The 1989 Aston Martin V-8 sits in a distinctive late hand-built grand touring era, when Aston Martin combined traditional craftsmanship with increasingly modern performance and road manners. By this point, the V-8 line covered more than one personality, and tire fitment follows that split. The 1989 Aston Martin V-8 uses radial tires, but the exact size depends on the sub-model, with 235/70R15 on the Base and 255/50R16 on Vantage and Volante models. That creates very different buying choices, from touring-oriented 15-inch fitments with multiple sidewall styles to lower-profile 16-inch performance radials. The key is confirming the exact sub-model and wheel diameter before comparing tire character, appearance, and road-use priorities.
Which Tire Size Is Right for The 1989 Aston Martin V-8
Two tire sizes apply to the 1989 Aston Martin V-8, and the right one depends first on the exact sub-model and wheel diameter. The Base uses a 15-inch radial fitment, while Vantage and Volante models use a 16-inch radial fitment. Before comparing brands, sidewall treatments, or tire series, confirm whether the car is running its correct 15-inch or 16-inch wheel setup.
235/70R15 is a modern metric radial size in which 235 denotes nominal section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 15 is the wheel diameter in inches. On the 1989 Aston Martin V-8, this size belongs to the Base model and delivers a more traditional 15-inch fitment. Available choices include Cooper, Avon, BFGoodrich, and Michelin, with blackwall, narrow whitewall, wide whitewall, redline, and raised white letter styles across series such as Silvertown Radial, Michelin XVS, Turbosteel, Cobra Radial G/T, and Radial T/A. It is the size to evaluate when preserving the Base model's intended wheel diameter and overall tire profile.
255/50R16 is a metric radial size where 255 indicates nominal section width in millimeters, 50 identifies a lower-profile sidewall relationship, R means radial construction, and 16 is the wheel diameter in inches. On the 1989 Aston Martin V-8, this size is used on Vantage and Volante models rather than the Base. The available choices here center on blackwall performance-oriented radials from BFGoodrich and Michelin, including g-Force Sport Comp 2 and Michelin Pilot Sport. This is the fitment to confirm when the car carries the 16-inch wheel package and the goal is maintaining the proper sub-model-specific tire format.
Sub-model identification matters on the 1989 Aston Martin V-8 because tire fitment is not shared across the range. The Base uses a different size and wheel diameter than the Vantage and Volante, so the first step is matching the tire to the exact version of the car.

1989 Aston Martin V-8 Base
The 1989 Aston Martin V-8 Base uses the 235/70R15 radial fitment on a 15-inch wheel. That opens up a broad mix of touring and period-style presentation choices, so selection often comes down to sidewall appearance, tire series, and wheel-width compatibility.
The 1989 Aston Martin V-8 Vantage uses the 255/50R16 radial fitment on a 16-inch wheel. Tire choice here is more focused, making it especially important to confirm wheel diameter and compare the available performance-oriented blackwall radial options carefully.
The 1989 Aston Martin V-8 Volante also uses the 255/50R16 radial fitment on a 16-inch wheel. Because this size differs from the Base model, owners should verify the actual wheel setup on the car before selecting between the available blackwall radial products.
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.
Best 1989 Aston Martin V-8 Tires for Sale
Available 1989 Aston Martin V-8 tires vary meaningfully by size. The 235/70R15 fitment includes Cooper, Avon, BFGoodrich, and Michelin options across several series and sidewall styles, while 255/50R16 choices are narrower and focus on blackwall performance radials from BFGoodrich and Michelin.
Common 1989 Aston Martin V-8 tire questions usually come down to sub-model fitment, 15-inch versus 16-inch wheels, product selection, appearance choices, and the checks worth making before putting a collector car back on the road.
Tire Size & Fitment
What tire size fits a 1989 Aston Martin V-8?
The 1989 Aston Martin V-8 uses two different radial tire sizes depending on sub-model. The Base uses 235/70R15, while the Vantage and Volante use 255/50R16. Those are not interchangeable descriptions of the same fitment, because they pair with different wheel diameters and reflect different tire profiles.
The practical first step is confirming whether the car is a Base, Vantage, or Volante and then verifying the actual wheel diameter on the vehicle. Many collector cars have had wheel changes over time, so selecting by model name alone is not enough if the current wheel setup no longer matches the original sub-model fitment.
What size rim does a 1989 Aston Martin V-8 use?
Rim diameter depends on the sub-model. A 1989 Aston Martin V-8 Base uses a 15-inch wheel with its 235/70R15 radial tire, while Vantage and Volante models use a 16-inch wheel with the 255/50R16 radial size. The tire size itself confirms the wheel diameter because the final number in each size is the rim size in inches.
That makes wheel verification especially important before ordering tires. A 15-inch tire cannot be mounted on a 16-inch wheel, and a 16-inch tire cannot be mounted on a 15-inch wheel. Measuring the wheel, checking existing sidewall markings, and confirming the car's exact sub-model helps avoid choosing the right size for the wrong wheel.
Do all 1989 Aston Martin V-8 sub-models use the same tire size?
No. The 1989 Aston Martin V-8 Base uses 235/70R15, while both the Vantage and Volante use 255/50R16. All three are radial fitments, but the Base runs a different wheel diameter and a different tire profile from the other two sub-models.
That difference affects more than just the number on the sidewall. It changes which products are available, what sidewall styles can be considered, and which wheel dimensions must be matched. Anyone replacing tires on one of these cars should start with the exact sub-model and then confirm that the wheels currently on the car still correspond to that sub-model's intended fitment.
Choosing the Right Tire
What should I consider when choosing a 1989 Aston Martin V-8 tire?
Start with the correct size for the exact sub-model: 235/70R15 for the Base or 255/50R16 for the Vantage and Volante. From there, compare radial tire series, brand, sidewall presentation, rim-width compatibility, and useful specification details such as load figures or tire weight where those differences matter to how the car is used.
A Base model owner may be balancing traditional appearance against touring use, while a Vantage or Volante owner is choosing within a smaller group of 16-inch performance-oriented radials. It also helps to look at the wheels already on the car, since aftermarket changes can alter what makes sense visually and dimensionally even when the sub-model fitment is known.
What sidewall styles are available for 1989 Aston Martin V-8 tires?
Sidewall choice depends heavily on tire size. In 235/70R15 for the 1989 Aston Martin V-8 Base, available styles include blackwall, narrow whitewall, wide whitewall, redline, and raised white letter. In 255/50R16 for the Vantage and Volante, the available products are blackwall radials.
That means appearance selection is much broader on the 15-inch Base fitment than on the 16-inch fitment. Buyers seeking a more restoration-oriented or period-style presentation will usually spend more time comparing sidewall treatments in 235/70R15, while 255/50R16 selection is more about tire series and wheel compatibility than decorative sidewall variety.
What brands offer tires for the 1989 Aston Martin V-8?
Tire brand availability varies by size. The 235/70R15 fitment is available from Cooper, Avon, BFGoodrich, and Michelin, while the 255/50R16 fitment is available from BFGoodrich and Michelin. Those brands appear across different series, which gives the Base fitment a broader range of choices than the larger 16-inch setup.
Brand comparison should come after size and wheel confirmation, not before. Once the correct fitment is established, it becomes easier to compare each brand's sidewall style, series character, rim-width range, and other visible product differences. That approach keeps the decision centered on the actual car rather than forcing a favorite brand into the wrong fitment.
Restoration & Appearance
Which tire should I choose for a period-style 1989 Aston Martin V-8?
A period-style choice starts with the correct sub-model size and wheel diameter. The Base uses 235/70R15, which offers the broadest range of appearance-oriented choices, including blackwall, whitewall, redline, and raised white letter variations. Vantage and Volante models use 255/50R16, where the available options are blackwall radials with a more modern performance presentation.
That makes the Base easier to tailor toward a traditional visual character, while the 16-inch cars remain more constrained by their fitment. When exact originality matters, it is wise to compare the tire's look against marque references, period photos, or restoration documentation so the chosen sidewall treatment supports the car's intended presentation.
How does tire construction affect the appearance of a restored 1989 Aston Martin V-8?
On the 1989 Aston Martin V-8, the primary fitments are already radial, so the appearance question is less about bias-ply versus radial and more about profile, wheel diameter, and sidewall treatment. A 235/70R15 Base tire presents differently from a 255/50R16 Vantage or Volante tire because the overall visual proportion and sidewall depth are not the same.
Sidewall styling then shapes the final impression. Redline, whitewall, or raised white letter treatments create a different look from a plain blackwall, even when the size is correct. Restored cars often look most coherent when the tire's profile and sidewall character suit the wheel design and the car's intended era-specific appearance rather than following current trends.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1989 Aston Martin V-8?
Yes. Wheel changes, altered wheel width, offset differences, suspension modifications, or body clearance changes can all affect tire fitment on a 1989 Aston Martin V-8. That matters even when the tire size matches the usual sub-model specification, because the car may no longer be running the same wheel and suspension relationship it had originally.
A careful check should include actual wheel diameter and width, steering clearance, fender clearance, and whether the car sits at the intended ride height. Collector cars often change hands with aftermarket parts already installed, so it is smart to inspect the full setup before choosing between 235/70R15 and 255/50R16 replacement tires.
What should I inspect before driving a 1989 Aston Martin V-8 on new tires?
Before driving, inspect the wheels, valve stems, and general suspension condition, then confirm the tires are mounted in the correct size for the car's sub-model and wheel diameter. It also helps to check for adequate clearance at full steering lock and under normal suspension movement, especially if the car has been modified or stored for long periods.
A collector car benefits from a broader road-use check as well. Look for fluid leaks, brake condition, old alignment issues, and any sign that the previous tires wore unevenly. New tires perform best when the vehicle itself is ready for use, so the first drive should be a controlled shakedown rather than an immediate long-distance outing.
How should tires on a collector 1989 Aston Martin V-8 be maintained?
Collector-car tire maintenance starts with regular pressure checks, visual inspections, and attention to age-related deterioration. Tires on a 1989 Aston Martin V-8 should be examined for cracking, bulges, cuts, tread wear, and slow air loss, even if the car is driven infrequently. Low annual mileage does not prevent rubber from aging.
Storage conditions matter almost as much as road use. Keeping the car away from prolonged sunlight, moisture, high heat, and ozone sources helps preserve tire condition over time. It is also useful to move the car periodically or store it in a way that reduces long-term flat spotting, then recheck pressures and sidewalls before returning it to regular road use.
