The 1975 Mercury Capri sits squarely in the era of sporty compact coupes that blended European character with practical road manners, and that makes tire choice especially important to how the car looks and feels today. For this model year, the Capri uses a 185/70R13 radial on a 13-inch rim, keeping fitment straightforward for most owners. That opens the door to several different interpretations of the same size, including traditional blackwall options as well as redline and wide whitewall presentations. Whether the goal is a clean driver, a restoration-minded look, or a more period-inspired road setup, the right decision starts with preserving the Capri’s correct size and wheel compatibility.
Which Tire Size Is Right for The 1975 Mercury Capri
The 1975 Mercury Capri uses one primary tire size: 185/70R13, a radial fitment for a 13-inch rim. Since the covered sub-model shares that same size, the main choice is not between multiple fitments but between tire styles, brand character, and the kind of appearance or driving use that best suits the car.
The 185/70R13 size uses a modern metric radial format: 185 is the nominal section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 13 is the wheel diameter in inches. On a 1975 Mercury Capri, this is the primary fitment and keeps the car in the radial-tire configuration associated with its period. Available choices include blackwall, redline, and wide whitewall styles, along with tire series from BFGoodrich, Avon, Dunlop, Michelin, and Vredestein. That makes this size less about finding what fits and more about selecting the right visual character, rim-width compatibility, and intended road use.
Sub-model fitment is straightforward for the 1975 Mercury Capri covered here. The Base model uses the same 185/70R13 radial size, so the focus stays on choosing the right tire style and product rather than sorting through multiple factory fitments.

1975 Mercury Capri Base
The 1975 Mercury Capri Base uses the same 185/70R13 radial tire size on a 13-inch rim. That keeps selection simple, letting the owner concentrate on blackwall versus period-style sidewall treatments, brand preference, and wheel-width compatibility before making a final choice.
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.

Tire Size & Fitment
What tire size fits a 1975 Mercury Capri?
The 1975 Mercury Capri uses a 185/70R13 radial tire. This is a metric radial size designed for a 13-inch wheel, and it is the primary fitment for the Capri covered here. The included Base sub-model uses that same size, which makes the starting point for tire selection fairly simple.
The practical step is confirming that the car still has the correct 13-inch wheels and that the wheel width falls within the tire’s usable range. If the Capri has been modified with different wheels or suspension changes over the years, check actual rim size and clearance before choosing among the available 185/70R13 tires.
What size rim does a 1975 Mercury Capri use?
The 1975 Mercury Capri uses a 13-inch rim with its 185/70R13 tire size. The size code itself confirms that wheel diameter, since the final number in a metric radial size is the rim diameter in inches. That makes wheel diameter verification straightforward when checking the car before buying tires.
Rim diameter is only part of the fitment picture, so wheel width still matters when comparing products. Several 185/70R13 options are intended for slightly different rim-width ranges, so it is worth measuring the actual wheel before making a final decision, especially if the Capri no longer has its original wheel setup.
Does the 1975 Mercury Capri Base use the same tire size?
Yes. The 1975 Mercury Capri Base uses the same 185/70R13 radial tire size. That means there is no separate primary size to sort out for the covered sub-model, and the basic fitment question stays consistent across the vehicle shown here.
Since the size does not change, the more useful comparison becomes the type of 185/70R13 tire you want to run. Owners can focus on sidewall appearance, tire series, rim-width compatibility, and overall condition of the car’s wheels and suspension rather than trying to determine whether a different sub-model fitment applies.
Choosing the Right Tire
What should I consider when choosing a 185/70R13 tire for a 1975 Mercury Capri?
Start with the correct size and construction: 185/70R13 radial on a 13-inch rim. From there, compare the details that shape how the Capri will look and be used, including sidewall style, tire series, brand, rim-width compatibility, and any stated load figures that may matter for your intended driving.
A Capri restored with a period-style theme may call for a different presentation than a road-driven car built around blackwall radials. It also helps to confirm the actual wheel width before narrowing choices, because some tires in this size are intended for slightly different rim-width ranges than others.
What sidewall styles are available for 1975 Mercury Capri tires?
The 1975 Mercury Capri’s 185/70R13 tire options include blackwall, redline, and wide whitewall styles. Blackwall choices are the most common in this size, while redline and 2-inch whitewall versions provide a more appearance-driven alternative for owners who want the tire to play a bigger visual role.
Sidewall style does not change the basic tire size, but it can change the whole personality of the car. A blackwall tends to keep the Capri looking understated and sporty, while a redline or wide whitewall leans more toward a personalized or restoration-oriented presentation without changing the fundamental 185/70R13 fitment.
What brands offer tires for the 1975 Mercury Capri?
185/70R13 tires for the 1975 Mercury Capri are available from BFGoodrich, Avon, Dunlop, Michelin, and Vredestein. Those brands cover several different radial tire series, so the buyer is not limited to one visual style or one product approach within the Capri’s primary size.
Brand choice should be weighed alongside the specific tire series, sidewall treatment, and wheel compatibility rather than by name alone. Two tires in the same 185/70R13 size can still differ in rim-width range, stated load figure, and appearance, which is often more useful than treating brand as the only deciding factor.
Restoration & Appearance
Which tire should I choose for a period-style 1975 Mercury Capri?
A period-style 1975 Mercury Capri should begin with the correct 185/70R13 radial size. From there, the choice depends on the look you want the car to carry, since this size is available in both understated blackwall form and more expressive sidewall treatments that can change the Capri’s visual character.
For a cleaner sporty presentation, a blackwall radial usually keeps the focus on the car itself. A redline or wide whitewall can create a stronger vintage-style statement, but exact originality should be checked against vehicle-specific historical references if that level of restoration detail matters to the project.
How does tire construction affect the appearance of a restored 1975 Mercury Capri?
On a restored 1975 Mercury Capri, construction affects appearance less through size format than through the way the tire presents itself on the car. Since the Capri uses a radial fitment in 185/70R13, the visual decision is mostly about the sidewall treatment and the overall style of the tire series you choose.
That means the car can look distinctly different even while staying in the same correct size. A simple blackwall keeps the presentation restrained and sporty, while redline or wide whitewall versions add more visual emphasis. Matching that choice to the car’s finish, wheels, and restoration goals usually matters more than chasing novelty.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1975 Mercury Capri?
Yes. Even though the 1975 Mercury Capri’s primary tire size is 185/70R13, modifications can change whether that size still works the same way on the car. Aftermarket wheels, different wheel widths, suspension lowering, altered ride height, or body changes can all affect clearance and overall tire selection.
A modified Capri should be checked at the wheel, not just by model year. Measure actual rim diameter and width, then inspect steering travel and fender clearance before committing to a tire. That is especially important if the car’s stance or wheel package has changed from the setup normally associated with 185/70R13.
What should I inspect before driving a 1975 Mercury Capri on new tires?
Before driving a 1975 Mercury Capri on new tires, inspect the wheels for correct diameter and sound condition, then check suspension and steering components for looseness or wear. Tire pressure should be set appropriately, and the car should be examined for any obvious clearance concerns at the fenders and during steering movement.
Collector cars often spend long periods parked, so it also helps to look for unrelated issues that can affect how new tires perform, such as uneven alignment, sticking brakes, or wheel damage. A careful first road test is worthwhile, especially after mounting fresh 185/70R13 radials on a car that has seen infrequent use.
How should 185/70R13 tires on a collector 1975 Mercury Capri be maintained?
185/70R13 tires on a collector 1975 Mercury Capri should be inspected regularly for pressure loss, sidewall cracking, cuts, bulges, uneven wear, and signs of age. Cars that are driven occasionally can still develop tire issues while sitting, so visual checks matter just as much as monitoring tread depth.
Proper storage also makes a difference. Keeping the Capri away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve tire condition over time. During the driving season, recheck pressures and general condition before longer trips so the car is not relying on tires that look acceptable but have aged poorly.
