1986 Aston Martin Tire Fitment Guide

1986 Aston Martin vehicles use two tire sizes: 235/70R15 and 255/60R15. The 235/70R15 size fits both the 1986 Aston Martin Lagonda and the 1986 Aston Martin V-8, while 255/60R15 is used on the 1986 Aston Martin V-8 only. Both sizes mount on 15-inch wheels. Rim width recommendations vary by tire: 235/70R15 products span 6.0 to 8.5 inches, while 255/60R15 products span 7 to 9 inches depending on the specific tire.

That means year and make alone are not enough if you are shopping for a 1986 Aston Martin V-8. The Lagonda buyer can focus directly on 235/70R15, but the V-8 buyer should confirm which wheel and tire package the car is actually wearing before selecting a product. When a car has changed hands several times, it is smart to verify the size on the sidewall and compare it to the wheel width already on the car.

On a 1986 Aston Martin, 235/70R15 is a metric radial size. The 235 is the nominal section width in millimeters, 70 is the aspect ratio, meaning the sidewall height is 70 percent of the section width, R identifies radial construction, and 15 is the wheel diameter in inches. On 1986 Aston Martin vehicles, this size serves as the shared fitment used by both the Lagonda and the V-8.

For a buyer, 235/70R15 is the broadest starting point because it works across the full 1986 Aston Martin model range. It also opens the widest mix of sidewall appearances, including blackwall, redline, and raised white letter styles. If your goal is to keep the car close to a refined grand touring look, this size gives you more visual and brand variation than the wider V-8-specific option.

On a 1986 Aston Martin, 255/60R15 is also a metric radial size. The 255 is the nominal section width in millimeters, 60 is the aspect ratio, R identifies radial construction, and 15 is the wheel diameter in inches. Within the 1986 Aston Martin range, this size is not shared across all models; it applies to the V-8 only.

That model-specific role is the important part. A 1986 Aston Martin V-8 owner may encounter either the shared 235/70R15 size or the wider 255/60R15, so the choice starts with the actual wheel and fitment on the car rather than personal preference alone. Because 255/60R15 products also carry different wheel-width requirements depending on brand and series, matching the tire to the wheel already fitted is especially important.

The right answer depends first on model and wheel fitment, not on whether one tire is inherently better. The 1986 Aston Martin Lagonda uses 235/70R15, while the 1986 Aston Martin V-8 may use either 235/70R15 or 255/60R15. Both are radial 15-inch sizes, but 255/60R15 is the V-8-specific option and carries a wider, lower-profile format than 235/70R15.

A Lagonda owner should stay with 235/70R15. A V-8 owner should confirm what is on the car now, check the wheel width, and then decide whether the car calls for the shared fitment or the wider V-8 setup. Once fitment is settled, the buying choice becomes more about sidewall appearance, brand character, and the speed rating marked on the exact tire rather than about construction, since both sizes are radial.

1986 Aston Martin tires are available with several sidewall appearances depending on size. In 235/70R15, the available styles include blackwall, redline, and raised white letter. In 255/60R15, the available styles include OWL and raised white letter. That gives 1986 Aston Martin buyers a wider visual range than many collector applications, especially in the shared 235/70R15 size.

For most Aston Martin restorations and touring cars of this era, blackwall is usually the most understated and elegant look, especially on a Lagonda or a formal-spec V-8. Raised white letter and OWL treatments lean more toward an Eighties performance presentation. Redline is a more stylized specialty look. The best choice depends on whether you are preserving a refined factory-like appearance or emphasizing a period-custom visual statement.

1986 Aston Martin vehicles are covered by several tire brands across the two sizes. The 235/70R15 size is available from Cooper, Avon, BFGoodrich, and Michelin. The 255/60R15 size is available from Goodyear, Cooper, and BFGoodrich. All of these offerings are radial tires, but they differ in sidewall styling, speed ratings, and wheel-width compatibility.

That brand spread gives you room to choose by purpose instead of chasing a single answer for every car. A buyer focused on a more European grand touring presentation may gravitate toward the blackwall touring-style offerings, while a buyer who wants a stronger period-performance look may prefer raised white letter or OWL choices. Once the correct size is settled, compare the exact sidewall style and speed symbol on the tire you are considering.

Rim width depends on the exact 1986 Aston Martin tire size and, in some cases, the specific tire series. For 235/70R15, the supported wheel widths run from 6.0 to 8.5 inches depending on the tire. For 255/60R15, wheel-width support runs from 7 to 9 inches depending on the tire, with some products tied to a single 7-inch or 8-inch wheel width. Both sizes use a 15-inch wheel diameter.

That range matters because two tires with the same size code do not always share the exact same wheel-width window. Before mounting anything on a 1986 Aston Martin, measure or verify the wheel width already on the car and compare it to the requirements of the exact tire you want. That step is especially important on a V-8, where the wider 255/60R15 fitment can narrow your wheel choices.

Inner-tube requirements vary by product on 1986 Aston Martin tires rather than staying uniform across both sizes. In 235/70R15, one tire is explicitly marked TL for tubeless use, while other products do not carry the same marking in the size description. The 255/60R15 group does not show a tube-type marking in the size descriptions. That means tube status should be confirmed on the exact tire you choose, not assumed from size alone.

The practical reason to check is that wheel design and tire construction need to agree. If your 1986 Aston Martin still wears original wheels, inspect their condition carefully and confirm whether the specific tire is intended for tubeless use or whether a tube is called for. Treat the sidewall marking on the actual product as the deciding reference before mounting, especially if the car has older wheels or has been off the road for long periods.

Both 1986 Aston Martin tire sizes use a 15-inch wheel diameter, so they are compatible at the diameter level. That means a 15-inch original wheel is the correct basic starting point for either 235/70R15 or 255/60R15. Wheel width is the next question, because 235/70R15 tires span roughly 6.0 to 8.5 inches while 255/60R15 tires span 7 to 9 inches depending on the exact tire.

In practice, a 1986 Aston Martin owner should not assume every original 15-inch wheel suits both sizes equally well. The shared wheel diameter simplifies things, but the wider 255/60R15 fitment can demand a broader wheel than some 235/70R15 applications. If your car is a V-8 and you are considering switching between those sizes, confirm the actual wheel width before making the change.

A stored 1986 Aston Martin should be kept in a cool, dry, dark space away from direct sunlight, electric motors, battery chargers, furnaces, and other ozone sources that can age rubber. Keep the tires clean, maintain proper inflation, and move the car periodically so the same contact patch is not carrying the load for months at a time. Radial tires generally tolerate storage better than older bias-ply designs, but they still age when left static and underinflated.

For a collector Aston Martin that spends long stretches parked, storage habits make as much difference as mileage. If the car will sit for an extended season, many owners either roll it occasionally or support it in a way that reduces prolonged tire loading. A breathable car cover helps the body, but tire life is preserved most by stable temperatures, darkness, clean floors, and keeping the tires out of contact with solvents or petroleum products.

Tires on a 1986 Aston Martin should be judged more by age and condition than by mileage alone. A collector car may accumulate very few miles while the rubber still hardens, cracks, or loses flexibility over time. A good rule is to begin careful age-based evaluation around five to seven years and to treat about ten years as a strong replacement consideration, even if tread depth still looks acceptable. The DOT date code on the tire is the key age reference.

That approach matters especially on a low-use grand touring car, because old tires can appear presentable while behaving very differently on the road. If a 1986 Aston Martin has been in storage, has unknown tire age, or still wears tires from a prior restoration, a close inspection is worthwhile before regular driving resumes. Date code, sidewall condition, and how well the tire still holds pressure matter far more than odometer miles.

Tires on a 1986 Aston Martin should be inspected before every drive and given a more thorough check before any extended outing. Look for sidewall cracking, weathering, cuts, bulges, uneven tread wear, and any sign that the tire has been run underinflated. Pressure should be checked regularly, not guessed at by appearance. If the tire or wheel setup involves tubes, valve stems and slow leaks deserve extra attention as part of the inspection routine.

A pre-drive walkaround is simple but valuable on a hand-built car that may not be driven daily. Run your eyes around the full sidewall and tread surface, and inspect the spare as well, since a vintage spare often ages out even when never used. On a 1986 Aston Martin prepared for touring events or longer weekend drives, that quick habit can catch problems before they become roadside interruptions.

A 1986 Aston Martin Lagonda belongs to an era when radial tires were the normal factory construction, and the Lagonda uses 235/70R15 within the 1986 Aston Martin range. Blackwall radials are the most natural visual match for the formal, luxury-oriented character of the model, although sidewall appearance can vary depending on market taste and later owner changes. No original-equipment brand should be assumed without checking factory literature or marque-specific references.

For a restoration-minded owner, the safest path is to start with the correct size and radial construction, then verify market- or delivery-specific details through Aston Martin clubs, factory brochures, or long-time marque specialists. That is especially useful with low-production British cars, where regional variations and prior restoration decisions can complicate what appears original. Getting the size, construction, and overall presentation right matters more than chasing an unverified brand assumption.

Correct tire fitment does matter when a 1986 Aston Martin is judged for authenticity. Judges and knowledgeable enthusiasts often notice whether the size is appropriate to the model, whether the construction matches the era, and whether the sidewall style suits the car's original presentation. On a 1986 Aston Martin, using the V-8-only 255/60R15 on a Lagonda would stand out as incorrect model fitment, just as an overly aggressive sidewall treatment might look out of place on a formal luxury sedan.

The practical standard is to match the car's intended character as closely as possible. A blackwall radial often aligns best with a restrained, factory-like look, while raised white letters or OWL can shift the car toward a more overt performance image. If you plan to enter judged events, consult the event rules and Aston Martin marque resources ahead of time, because some clubs care deeply about sidewall presentation while others focus primarily on size and overall correctness.

For a 1986 Aston Martin in 235/70R15, the Michelin XVS and Avon Turbosteel are both blackwall radials, but they are not identical in their markings and details. The Michelin carries an H speed rating, which is rated to 130 mph, while the Avon carries a V speed rating, which is rated to 149 mph. The Michelin also shows a 6.00 to 8.50 inch wheel-width range, while the Avon is presented without a wheel-width range in the same way.

That means the choice is less about basic fitment and more about the exact character and specification you want from a blackwall touring tire. If speed-symbol preference matters to you, compare the sidewall marking carefully before making a decision. If wheel width is a question on your car, the Michelin's stated range gives you a clear mounting window to work from, while the Avon may call for an extra verification step with the exact product before installation.

1986 Aston Martin tires can be suitable for highway driving when they are the correct size, properly inflated, in sound condition, and used within the speed rating marked on the tire. In the 235/70R15 size, available speed ratings include H at 130 mph and V at 149 mph. In the 255/60R15 size, one available product carries an S rating at 112 mph. Since these are radial tires, the road manners will generally align with what buyers expect from modern reproduction or replacement radials rather than earlier bias-ply behavior.

The tire's speed symbol is only one part of the picture on a 1986 Aston Martin. Highway safety also depends on brake condition, suspension health, alignment, age of the rubber, and whether the car has been sitting unused. A grand touring Aston may feel capable at speed, but any long-stored collector car deserves a careful mechanical inspection before regular highway use resumes, even if the tread depth still looks good.

Inflation pressure for a 1986 Aston Martin should follow the vehicle manufacturer's recommendation first, with the tire maker's maximum-pressure marking used only as the tire's upper load-rating reference. Available load-and-pressure markings in this range include 1,896 pounds at 35 psi, 1,819 pounds, 1,885 pounds at 35 psi, and 1,796 pounds at 35 psi depending on the exact tire. Those figures are not interchangeable setup recommendations across all sizes or all products.

The safest approach is to use the owner's manual or factory placard as the baseline for normal driving, then make sure the tire you choose is appropriate for that application. Do not copy a pressure figure from one 1986 Aston Martin tire size to another just because both mount on 15-inch wheels. Size, load capacity, sidewall design, and the exact tire series all matter when you are setting pressures correctly.

Before a longer drive in a 1986 Aston Martin, inspect all four tires and the spare for cracking, bulges, tread damage, uneven wear, and proper inflation. Make sure the valve stems are in good condition and confirm whether your chosen tire setup is tubeless or needs any additional tube-related attention. Aged tires that have spent years parked can look acceptable at a glance while still being a poor candidate for distance driving.

Tires are only one part of the checklist on an older Aston Martin, so pair that inspection with a broader pre-drive review of brakes, fluids, cooling, and suspension. On the tire side, the most important final checks are pressure consistency and confidence that each tire matches the wheel width and model application. That gives you a much better starting point for a trouble-free touring drive than relying on appearance alone.
