The 1991 Mercury Capri arrived as a small front-drive convertible aimed at buyers who wanted open-air fun in a compact, modern package. Its combination of tidy proportions and early-1990s styling gives it a very different feel from larger domestic convertibles of the same period, and tire fitment plays a big role in preserving that balance. The 1991 Mercury Capri uses two primary radial tire sizes, with 185/60R14 for the Base and 195/50R15 for the XR2. That makes the key decision less about vintage-style construction and more about matching the correct sub-model, wheel diameter, and performance character. A careful selection keeps the car's stance, handling feel, and clearance aligned with the setup actually on the vehicle.
Which Tire Size Is Right for The 1991 Mercury Capri
The 1991 Mercury Capri uses two different primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. The Base uses a 14-inch radial setup, while the XR2 uses a 15-inch radial setup, so confirming the model and the wheels on the car is the first step before comparing tire choices.
185/60R14 is a metric radial size in which 185 identifies the nominal section width in millimeters, 60 is the aspect ratio, R indicates radial construction, and 14 is the rim diameter in inches. On the 1991 Mercury Capri, this size belongs with the Base model's 14-inch wheel fitment and keeps the car in its intended modern radial format. Available choices in this size center on Michelin and a blackwall presentation rather than multiple sidewall treatments. It is the size to evaluate when maintaining Base-model wheel compatibility and preserving the smaller-diameter Capri setup.
195/50R15 is a metric radial size with a 195-millimeter nominal section width, a 50-series profile, radial construction, and a 15-inch rim diameter. For the 1991 Mercury Capri, this size is used on the XR2 and reflects a different wheel and tire package than the Base model. Product choices here include BFGoodrich and Michelin, both in blackwall form, with differences in tire series, rim-width range, weight, and related specifications. This is the size to review when the car carries the XR2 setup or any 15-inch wheel arrangement that matches the original configuration.
Sub-model fitment matters on the 1991 Mercury Capri because the covered versions do not share the same tire size or wheel diameter. Identifying whether the car is a Base or an XR2 is the first step before choosing a replacement tire.

1991 Mercury Capri Base
The 1991 Mercury Capri Base uses a 185/60R14 radial tire on a 14-inch wheel setup. That makes tire selection fairly straightforward once the original wheel diameter is confirmed, with the focus shifting to matching the correct modern radial size and intended road use.
The 1991 Mercury Capri XR2 uses a 195/50R15 radial tire and a different wheel diameter than the Base model. Tire selection therefore starts with confirming the 15-inch XR2 arrangement, then comparing available radial options by brand, tire series, and wheel-width compatibility.
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 1991 Mercury Capri Tires for Sale
Available 1991 Mercury Capri tires are all radial blackwall designs, with Michelin covering both Capri sizes and BFGoodrich adding another 195/50R15 option for the XR2. The main points of comparison are sub-model fitment, tire series, rim-width range, weight, and related performance-oriented specifications.
Common 1991 Mercury Capri tire questions usually come down to confirming the correct size for the Base or XR2, understanding the 14-inch versus 15-inch wheel difference, and comparing available radial tire choices for appearance, fitment, and regular road use.
Tire Size & Fitment
What tire size fits a 1991 Mercury Capri?
A 1991 Mercury Capri uses one of two radial tire sizes depending on sub-model. The Base uses 185/60R14, while the XR2 uses 195/50R15. Those sizes are tied to different wheel diameters, so the correct answer depends on which version of the car is being fitted.
The safest starting point is to confirm whether the car is a Base or an XR2 and then verify the actual wheel diameter already on the vehicle. On older cars, wheel changes are common, so checking the tire sidewall and the wheel itself helps prevent choosing a 14-inch tire for a 15-inch setup or the reverse.
What size rim does a 1991 Mercury Capri use?
The 1991 Mercury Capri uses two rim diameters depending on sub-model. The Base is paired with a 14-inch wheel and 185/60R14 tires, while the XR2 uses a 15-inch wheel with 195/50R15 tires. The tire size and rim diameter work together and should be matched correctly.
Wheel diameter is the first thing to confirm before ordering tires because a 14-inch tire cannot be mounted on a 15-inch wheel, and a 15-inch tire cannot be mounted on a 14-inch wheel. It also helps to check wheel width, especially if the car has aftermarket wheels or if the original setup has been changed over time.
Do all 1991 Mercury Capri sub-models use the same tire size?
No, the 1991 Mercury Capri sub-models covered here do not use the same tire size. The Base uses 185/60R14, and the XR2 uses 195/50R15. Both are radial tires, but they are built for different rim diameters and represent two distinct fitment paths.
That difference means the buyer should identify the exact sub-model before comparing brands or tire series. It is also wise to confirm the actual wheels on the car, since a Capri that has been modified or repaired over the years may no longer carry its original wheel package, even if the trim badge suggests otherwise.
Choosing the Right Tire
What should I consider when choosing a tire for a 1991 Mercury Capri?
Start with the correct primary size for the car's sub-model: 185/60R14 for the Base or 195/50R15 for the XR2. From there, compare radial construction details such as rim-width compatibility, tire series, weight, and any load information that appears with the product. Those details help separate one suitable option from another.
A good choice depends on how the Capri is actually used. A stock car on original wheels may call for a straightforward size match, while a car with replacement wheels should have both diameter and width checked before a decision is made. That keeps the tire choice aligned with clearance, handling balance, and everyday drivability.
What brands offer tires for the 1991 Mercury Capri?
Michelin and BFGoodrich both offer tires for the 1991 Mercury Capri, depending on size. Michelin covers both Capri fitments with the Pilot Exalto PE2, while BFGoodrich appears in 195/50R15 with the g-Force Sport Comp 2. The available brand mix is broader for the XR2 than for the Base size.
Brand choice should still begin with the right sub-model size rather than with the label on the sidewall. Once the correct size is confirmed, compare the tire series and supporting specifications that matter to the way the car will be driven. That approach is more useful than assuming one brand automatically suits every Capri the same way.
How do I choose between the available 195/50R15 tires for a 1991 Mercury Capri?
The 195/50R15 fitment for the 1991 Mercury Capri XR2 includes options from BFGoodrich and Michelin, both as blackwall radial tires. The main differences are the tire series, rim-width range, weight, and related product details rather than a major change in overall fitment category.
An XR2 owner should confirm that the wheel falls within the stated rim-width range before comparing the finer points of the available tires. It also helps to think about whether the goal is routine road use, a sharper performance-oriented character, or a more familiar touring feel, since tire-series differences can shape the overall selection.
Restoration & Appearance
Which tire should I choose for a period-style 1991 Mercury Capri?
A period-style 1991 Mercury Capri usually starts with keeping the original fitment path intact for the correct sub-model. That means 185/60R14 radial tires for the Base or 195/50R15 radial tires for the XR2. Staying with the proper size and wheel diameter does more for the car's visual balance than chasing an unrelated alternative.
Since the available products here are blackwall radials, the appearance decision is more about preserving the Capri's clean early-1990s look than about choosing between dramatic sidewall treatments. Owners pursuing exact restoration standards may still want to compare old photographs, brochures, or marque-specific references before settling on a particular brand or tire series.
Does correct tire fitment matter for a 1991 Mercury Capri restoration?
Correct tire fitment matters on a 1991 Mercury Capri restoration because the car uses different sizes for the Base and XR2, along with different wheel diameters. Using the proper 185/60R14 or 195/50R15 setup helps keep the car's stance, wheel-to-tire proportion, and intended character closer to the original layout.
Fitment accuracy also affects how convincing the finished restoration looks when viewed from the side, especially on a compact convertible where wheel and tire proportions are easy to notice. Even when the goal is a driver rather than a show car, matching the right size to the right sub-model avoids a visually awkward result and simplifies future tire replacement.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1991 Mercury Capri?
Yes, modifications can affect tire fitment on a 1991 Mercury Capri. Changes to wheel diameter, wheel width, offset, ride height, or suspension components can alter how a 185/60R14 or 195/50R15 tire sits in the wheel opening and how much clearance it has during steering and suspension movement.
A Capri with aftermarket wheels should have the wheel size checked before a tire is chosen by sub-model alone. It is also smart to inspect clearance at the fender, inner wheelhouse, and steering range, especially if the car has been lowered or repaired. Those checks help avoid rubbing issues that a stock-spec tire size alone cannot rule out.
What should I inspect before driving a 1991 Mercury Capri on new tires?
Before driving a 1991 Mercury Capri on new tires, inspect the wheels for the correct diameter and condition, confirm that the tire size matches the Base or XR2 setup, and check that the tires are seated properly and inflated evenly. A quick look at valve stems, lug hardware, and visible clearance is also worthwhile.
Older convertibles can sit for long periods, so it helps to look beyond the tires themselves. Check for suspension wear, alignment-related tire scrub, and any interference while turning lock to lock. A short, careful road test can reveal vibration, pulling, or rubbing early, before the car is taken on regular drives or longer highway use.
How often should tires on a 1991 Mercury Capri be inspected?
Tires on a 1991 Mercury Capri should be inspected regularly, especially if the car is driven infrequently or stored for long stretches. Routine checks should include pressure, tread condition, cuts, bulges, uneven wear, and signs of sidewall aging. A quick inspection before each drive is a sensible habit on an older convertible.
Cars that spend much of their time parked can develop problems that are easy to miss until the next outing. Looking for slow air loss and storage-related deterioration helps catch issues early. It also pays to recheck the tires after the first few drives on a newly fitted set, since seating, pressure stability, and clearance can reveal themselves over time.
