The 1985 Aston Martin V-8 sits in the final chapter of Aston Martin’s hand-built Newport Pagnell grand touring era, where traditional British coachwork and strong V-8 performance came together in a distinctly low-volume luxury car. Tire choice matters here because the covered 1985 V-8 range uses two different 15-inch radial sizes depending on sub-model: 235/70R15 or 255/60R15. That creates a real difference in stance, profile, and product selection, especially between the standard V-8 and the Vantage. Available choices include blackwall, whitewall, wide whitewall, redline, RWL, and OWL treatments across several recognizable radial series. The right decision starts with confirming the exact sub-model, then matching the tire’s look and fitment to the car’s intended use.
Which Tire Size Is Right for The 1985 Aston Martin V-8
Two tire sizes apply to the 1985 Aston Martin V-8, and the right one depends on the specific sub-model rather than a wheel-diameter change, since both use 15-inch radial tires. The first step is confirming whether the car is a Base, Vantage, or Volante, because that determines whether you should be looking at 235/70R15 or 255/60R15 before comparing brands, sidewall styles, and rim-width requirements.
In 235/70R15, the 235 is the section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 15 is the wheel diameter in inches. On the 1985 Aston Martin V-8, this size suits the Base and Volante sub-models and keeps the selection focused on a traditional grand-touring radial format. Available choices include blackwall, narrow whitewall, wide whitewall, redline, and RWL sidewalls from Avon, BFGoodrich, Cooper, and Michelin across series such as Turbosteel, XVS, Silvertown Radial, Cobra Radial G/T, and Radial T/A. It is the size to evaluate when the car’s original-style profile and 15-inch wheel setup point toward the standard V-8 fitment.
In 255/60R15, the 255 denotes section width in millimeters, the 60 is the aspect ratio, R marks radial construction, and 15 indicates a 15-inch rim. This size is associated with the 1985 Aston Martin V-8 Vantage and represents a lower-profile metric radial than the 235/70R15 used on other sub-models. Product choices center on Goodyear, Cooper, and BFGoodrich, with OWL and RWL sidewall treatments in series such as Customgard Flexten, Eagle GT, Cobra Radial G/T, and Radial T/A. It deserves a careful look when the car is a Vantage and the wheel width and overall setup need to match this wider tire format.
Sub-model identification matters on the 1985 Aston Martin V-8 because tire fitment is not the same across the full range. The Base and Volante share one size, while the Vantage uses a different radial on the same 15-inch wheel diameter.

1985 Aston Martin V-8 Base
The 1985 Aston Martin V-8 Base uses the 235/70R15 radial size. Tire selection here is less about sorting through multiple fitments and more about choosing the right brand, sidewall treatment, and rim-width compatibility for the car’s appearance and intended road use.
The 1985 Aston Martin V-8 Vantage uses the wider 255/60R15 radial size rather than the 235/70R15 fitted to other covered sub-models. That makes wheel-width confirmation especially important before comparing OWL and RWL options or choosing among the available performance-oriented radial series.
The 1985 Aston Martin V-8 Volante uses the same 235/70R15 radial size as the Base model. That keeps fitment straightforward, allowing the decision to center on sidewall appearance, brand preference, and whether the car is being kept in a more understated touring style or a more restoration-minded presentation.
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 1985 Aston Martin V-8 Tires for Sale
Available 15-inch radial choices for the 1985 Aston Martin V-8 vary by sub-model and include Cooper, Avon, BFGoodrich, Michelin, and Goodyear offerings. Buyers can compare series, sidewall styles such as blackwall, whitewall, redline, RWL, and OWL, plus rim-width and load-capacity details within each size.
These FAQs focus on the two tire sizes used on the 1985 Aston Martin V-8, how fitment changes by sub-model, and what to compare when choosing between available radial tires for restoration, touring, and road use.
Tire Size & Fitment
What tire size fits a 1985 Aston Martin V-8?
The 1985 Aston Martin V-8 uses two different radial tire sizes depending on sub-model. The Base and Volante use 235/70R15, while the Vantage uses 255/60R15. Both sizes are built for 15-inch wheels, but they are not the same profile or width, so the sub-model matters before any product comparison begins.
The practical first step is confirming exactly which version of the car is in the garage, then checking the actual wheel setup on the vehicle. A car that has had wheel changes, replacement rims, or suspension modifications may no longer match the original sub-model fitment, so wheel width and clearance should be verified before choosing a tire.
What size rim does a 1985 Aston Martin V-8 use?
The covered tire sizes for the 1985 Aston Martin V-8 both use a 15-inch rim diameter. That applies whether the car takes 235/70R15 or 255/60R15, so the key difference across the range is the tire size itself rather than a change in wheel diameter.
Rim diameter is only part of the picture. Width also matters, especially when moving from the 235-section tire used on the Base and Volante to the wider 255-section tire used on the Vantage. Before ordering tires, confirm the wheel’s actual width and inspect for any aftermarket wheel changes that could affect fitment, sidewall shape, or clearance.
Do all 1985 Aston Martin V-8 sub-models use the same tire size?
No. The 1985 Aston Martin V-8 Base and Volante share the 235/70R15 radial size, while the Vantage uses 255/60R15. All three covered sub-models stay on 15-inch rims, but the Vantage fitment is wider and lower in profile than the size used on the other versions.
That difference means a buyer should not assume one size applies across the whole V-8 range. The easiest mistake is choosing by year and model name alone without checking the exact sub-model or the wheels currently on the car. Confirming both before selecting a tire helps avoid mismatched proportions and possible clearance or compatibility issues.
Choosing the Right Tire
What should I consider when choosing a 235/70R15 tire for a 1985 Aston Martin V-8?
Start with the intended character of the car. On a 1985 Aston Martin V-8 Base or Volante, 235/70R15 choices include blackwall, narrow whitewall, wide whitewall, redline, and RWL designs from Avon, BFGoodrich, Cooper, and Michelin, so the decision often comes down to whether the car is being kept understated, more sporting, or more restoration-oriented in appearance.
Beyond appearance, compare the tire series, rim-width specifications, and load figures attached to each product. A Michelin XVS presents a different type of offering than a BFGoodrich Silvertown Radial or Cooper Cobra Radial G/T, even within the same size. Matching the tire to the car’s wheel width and how the car is actually driven is more useful than choosing by sidewall style alone.
What sidewall styles are available for 1985 Aston Martin V-8 tires?
Sidewall choice varies by size. In 235/70R15, available styles include blackwall, narrow whitewall, wide whitewall, redline, and RWL. In 255/60R15, the available products center on RWL and OWL sidewalls. That gives the standard V-8 and Volante a broader appearance range, while the Vantage selection leans more toward performance-era styling.
The best sidewall treatment depends on how the car is being presented. A blackwall or subtle whitewall can suit a refined grand-touring look, while redline, RWL, or OWL can shift the visual character noticeably. The important point is to choose within the correct size for the sub-model first, then use the sidewall as the finishing detail rather than the starting point.
What brands offer tires for the 1985 Aston Martin V-8?
The available brands for the 1985 Aston Martin V-8 include Cooper, Avon, BFGoodrich, Michelin, and Goodyear. Brand availability depends on tire size, with 235/70R15 carrying the broadest assortment and 255/60R15 focusing on Goodyear, Cooper, and BFGoodrich options.
Brand alone should not drive the decision. It is better to compare which series each brand offers in the correct size, what sidewall styles are available, and whether the wheel width matches the tire’s intended rim range. That approach keeps the choice tied to the car’s actual fitment and appearance instead of treating every 15-inch radial as the same.
Restoration & Appearance
Which tire should I choose for a period-style 1985 Aston Martin V-8?
A period-style choice starts with the correct sub-model size. That means 235/70R15 for the Base and Volante, or 255/60R15 for the Vantage. Once the fitment is right, the visual direction comes from the available tire series and sidewall treatments, which range from understated blackwalls to whitewall, redline, RWL, and OWL presentations.
A restoration-minded owner should decide whether the goal is a restrained grand-touring look or a stronger performance-era statement. Tire series such as Michelin XVS, Avon Turbosteel, BFGoodrich Silvertown Radial, Radial T/A, and Cooper Cobra Radial G/T each create a different impression. For exact originality, marque-club references and vehicle-specific historical documentation remain the best final check.
How does tire construction affect the appearance of a restored 1985 Aston Martin V-8?
On the 1985 Aston Martin V-8, the primary fitments covered here are radial tires, so the appearance discussion centers less on bias-ply versus radial shape and more on sidewall treatment, profile, and tire series. The Base and Volante use a taller-profile 235/70R15, while the Vantage uses a wider, lower-profile 255/60R15 that changes the car’s visual stance.
That means a restored car can look noticeably different even when both tires are technically correct for the model range. Choosing the wrong size for the sub-model can alter the proportions more than choosing between two radial brands in the same size. Begin with correct fitment, then refine the presentation through blackwall, whitewall, redline, RWL, or OWL styling.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1985 Aston Martin V-8?
Yes. Even though the covered 1985 Aston Martin V-8 fitments are 235/70R15 and 255/60R15 on 15-inch rims, modifications can change what works on the car. Aftermarket wheels, altered wheel width, suspension changes, ride-height adjustments, or bodywork differences can all affect how a tire sits and whether it clears properly.
A car that has been changed from stock should be measured rather than assumed. Check wheel diameter and width first, then inspect inner and outer clearances at full steering lock and through suspension travel. That matters especially when a Vantage-size 255/60R15 is involved, since a wider section calls for closer attention to the complete wheel and chassis setup.
What should I inspect before driving a 1985 Aston Martin V-8 on new tires?
Before road use, inspect the wheels, valve stems, and the overall condition of the suspension and steering components. The tire should match the correct sub-model size, seat properly on the wheel, hold air consistently, and show no sign of interference. It is also worth confirming that the car’s alignment and brake condition are in good order before putting miles on fresh rubber.
A short, careful test drive is the next sensible step. Listen for rubbing, feel for vibration, and recheck air pressure after the tires have settled in. On a collector car that may sit for long periods, a close visual inspection remains important even with new tires, because wheel condition, stored age-related issues, and suspension wear can still affect road behavior.
How should tires on a collector 1985 Aston Martin V-8 be maintained?
Collector-car tires should be checked regularly for air pressure, uneven wear, cuts, bulges, and sidewall cracking, even when mileage is low. On a 1985 Aston Martin V-8, that means watching the actual fitted size closely, whether the car uses 235/70R15 or 255/60R15, and making sure the tires remain appropriate for the wheel and the way the car is stored.
Storage conditions matter as much as mileage on a low-use grand tourer. Keep the car away from prolonged sunlight, excess heat, moisture, and ozone sources such as electric motors when possible. Moving the car periodically, maintaining correct inflation, and inspecting the tread and sidewalls before any longer drive will do more for safe road use than appearance checks alone.
