The 1987 Sterling 825 reflects a brief and distinctive chapter in the U.S. luxury-import market, combining British branding with a refined front-wheel-drive sedan layout that stood apart from domestic offerings of the period. Buyers drawn to these cars today are often balancing preservation with practical road use, especially on vehicles that have spent long stretches parked. The 1987 Sterling 825 uses a 195/65R15 radial tire, giving it a straightforward modern metric fitment on a 15-inch wheel. That makes the main decision less about deciphering multiple sizes and more about choosing the right radial tire for the car’s intended appearance, use, and wheel setup.
Which Tire Size Is Right for The 1987 Sterling 825
The 1987 Sterling 825 uses one primary tire size: 195/65R15. It is a radial tire fitment on a 15-inch rim, and both the 825 S and 825 SL share that same size, so the focus shifts from identifying fitment to choosing the right tire within that specification and confirming the car still has the correct wheel setup.
A 195/65R15 tire uses a 195-millimeter nominal section width, a 65-series aspect ratio, radial construction, and a 15-inch rim diameter. On the 1987 Sterling 825, this is the primary fitment and it reflects the car’s late-1980s move into modern metric radial sizing rather than older numeric or alphanumeric bias-ply formats. Because the size itself is straightforward, the real selection process centers on making sure the wheel diameter is still correct and choosing a tire that suits the car’s intended use, whether that means regular road driving or a more preservation-oriented ownership approach.
Tire fitment is simple across the covered 1987 Sterling 825 sub-models because both use the same primary size. Checking the exact sub-model still helps confirm that the car has not been altered from its original wheel and tire configuration over time.

1987 Sterling 825 S
The 1987 Sterling 825 S uses the same 195/65R15 radial fitment as the rest of the covered model range. That keeps tire selection focused on choosing an appropriate radial tire and confirming that the car still carries the correct 15-inch wheel setup.
The 1987 Sterling 825 SL also uses the 195/65R15 radial size, so there is no separate tire-size split between the covered sub-models. The practical next step is comparing tire choices within that size while checking wheel condition, wheel diameter, and overall clearance on the specific car.
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.
Frequently Asked Questions
These FAQs focus on 1987 Sterling 825 tire size, 15-inch rim fitment, sub-model consistency, tire selection, and the checks that matter before putting a low-use late-classic sedan back on the road.
Tire Size & Fitment
What tire size fits a 1987 Sterling 825?
The 1987 Sterling 825 uses a 195/65R15 tire. This is a metric radial size, and it is the primary fitment used across the covered model range, including the 825 S and 825 SL.
That means the first step is usually not choosing between multiple factory sizes, but confirming that the car still has the correct 15-inch wheels. On a vehicle of this age, it is smart to verify the current wheel diameter and inspect for any past wheel or suspension changes before selecting a new set of tires.
What size rim does a 1987 Sterling 825 use?
The 1987 Sterling 825 uses a 15-inch rim diameter with its 195/65R15 tire size. The 15 at the end of the tire size is the wheel diameter the tire is built to mount on.
Rim diameter is the non-negotiable starting point, because a 15-inch tire must be mounted on a 15-inch wheel. It is also worth checking the actual wheel width and condition, especially on a car that may have been modified or stored for long periods, since wheel condition can matter just as much as tire size.
Do all 1987 Sterling 825 sub-models use the same tire size?
Yes. The covered 1987 Sterling 825 sub-models use the same 195/65R15 radial tire size. That includes both the 825 S and the 825 SL, so there is no tire-size split between those versions.
Even with shared fitment, it is still wise to confirm what is physically on the car before ordering replacement tires. Older imported sedans sometimes pick up aftermarket wheels over the years, and a previous owner may have changed tire sizing for availability, appearance, or ride preference.
Choosing the Right Tire
What should I consider when choosing a 195/65R15 tire for a 1987 Sterling 825?
Start with the correct size, which is 195/65R15, and confirm that the Sterling still has the proper 15-inch wheels. Since this is already a radial fitment, the main decision is choosing a tire that suits how the car is actually used, whether that is regular driving, occasional weekend use, or longer periods of storage.
A careful choice also means looking at wheel condition, overall tire age if older tires are still mounted, and any changes to suspension height or alignment history. On a late-1980s sedan like the 825, a correct-size radial that matches the car’s actual setup is more important than chasing an unusual substitute.
How do I choose between the available 195/65R15 tires for a 1987 Sterling 825?
The most useful comparison points are still the basics: correct size, proper 15-inch rim fitment, and whether the tire suits the way the car is driven. Because the 1987 Sterling 825 uses a modern metric radial size, the choice usually comes down to selecting a tire that supports dependable road use on a collector-era sedan.
It helps to inspect the car as part of the decision, not just the tire catalog. A Sterling that has sat for years may need attention to alignment, suspension wear, or wheel condition, and those factors can affect how well a new set of tires performs once the car is back in regular service.
What tire series are available for the 1987 Sterling 825?
The key fitment point for the 1987 Sterling 825 is the 195/65R15 radial size rather than a wide spread of vintage series designations. Unlike older collector vehicles that use numeric or alphanumeric bias-ply sizing, this Sterling uses a modern metric radial format that is already easy to interpret.
That makes series-style comparison less central than confirming the correct size and wheel diameter. A buyer will usually get more value from checking the actual wheel setup, tire age, and the car’s intended use than from trying to force a vintage-style selection process onto a later metric-radial fitment.
Restoration & Appearance
Which tire should I choose for a period-style 1987 Sterling 825?
A period-style starting point for a 1987 Sterling 825 is the original-size 195/65R15 radial format. Keeping the correct metric radial size preserves the car’s late-1980s fitment character far better than moving to an unrelated older bias-ply or vintage alphanumeric tire style.
For a restoration-minded car, matching the original size is usually the first visual and functional priority. Exact originality questions beyond size should be checked against marque references, period photos, or surviving vehicle history, especially if the goal is a highly faithful presentation rather than a general roadworthy refurbishment.
Does correct tire fitment matter for a 1987 Sterling 825 restoration?
Yes, correct tire fitment matters because it affects both the appearance and road manners of a restored 1987 Sterling 825. Using the proper 195/65R15 radial size helps the car retain the proportions and stance expected of a late-1980s luxury sedan.
Restoration choices are rarely just cosmetic, since an incorrect size can also create questions around wheel compatibility and clearance. Even on a driver-quality project, staying with the proper size is one of the simplest ways to keep the car visually coherent while avoiding unnecessary fitment complications.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1987 Sterling 825?
Yes. Even though the 1987 Sterling 825 uses a straightforward 195/65R15 radial fitment, modifications can change what actually works on the car. Aftermarket wheels, altered ride height, replacement suspension parts, or body repairs can all affect clearance and the wheel dimensions a tire must work with.
That is why the current setup matters as much as the original size. A Sterling that still has stock-style 15-inch wheels is one situation, while a car with different offsets or suspension changes needs a closer inspection before replacement tires are chosen and put into service.
What should I inspect before driving a 1987 Sterling 825 on new tires?
Inspect the wheels, valve stems, and the overall condition of the suspension and steering before putting a 1987 Sterling 825 back into regular road use on new tires. It also helps to look for uneven wear on the old tires, since that can point to alignment or mechanical issues that new tires will not solve.
A sound inspection should also include checking for cracked bushings, wheel damage, and any signs of rubbing inside the wheelhouse. On an older sedan that may have seen limited use, these checks can prevent the new 195/65R15 tires from being compromised by problems that were already present.
How often should tires on a 1987 Sterling 825 be inspected?
Tires on a 1987 Sterling 825 should be inspected regularly, with extra attention if the car is driven infrequently or stored for long periods. Collector-era cars often age their tires through time and storage conditions as much as through mileage, so visual inspection matters even when tread looks acceptable.
A practical routine is to check pressure, sidewall condition, tread surface, and any signs of air loss before road use and again before longer drives. Storage near heat, sunlight, or ozone sources can accelerate tire aging, which is why low-mileage cars should never be judged by tread depth alone.
