The 1967 Mercury Cougar arrived as Mercury’s more upscale take on the compact pony car formula, blending long-hood styling with a more refined personality than many of its contemporaries. That mix of sporty presence and showroom polish still shapes how owners approach restoration and road use today. Tire fitment centers on two 14-inch bias-ply sizes, 735-14 and F70-14, with the exact choice tied to configuration. Within those sizes, period-style options include blackwall, narrow whitewall, redline, pin white stripe, and raised white letter presentations across familiar vintage series. The right choice comes down to matching the car’s sub-model, wheel setup, and the look you want the Cougar to carry.
Which Tire Size Is Right for The 1967 Mercury Cougar
The 1967 Mercury Cougar uses two primary tire sizes, and the first step is confirming the exact sub-model before choosing a tire. Both fitments are bias-ply designs for 14-inch rims, but they serve different applications and open up different product choices, sidewall treatments, and radial-equivalent considerations.
A 735-14 uses the older numeric bias-ply sizing system, with the leading number indicating nominal section width in inches and the final number indicating a 14-inch rim. On the 1967 Mercury Cougar, this is a traditional bias-ply fitment that suits owners keeping a more stock-style driving feel and vintage tire presentation. Available choices include BFGoodrich Silvertown Classic Bias Ply versions in blackwall or narrow whitewall form. This size is worth evaluating when the car uses the corresponding wheel setup and the goal is a restrained, restoration-oriented appearance.
F70-14 uses the vintage alphanumeric bias-ply system, where the letter identifies the tire’s size class, the series number reflects its profile family, and the 14 designates rim diameter. For the 1967 Mercury Cougar, this size is also a 14-inch bias-ply fitment, but it carries a broader range of period-style choices. Firestone and Goodyear offer it in series such as Wide Oval, Custom Wide Tread, and Speedway Wide Tread, with redline, pin-white-stripe, and raised white letter sidewalls. It is the size to examine closely when sub-model fitment points to F70-14 and appearance detail matters.
Sub-model fitment matters on the 1967 Mercury Cougar because tire size is not identical across the covered versions. The Base model can use either primary size, while the High Performance Big Eng. configuration centers on F70-14, so identifying the car correctly comes before comparing tire styles.

1967 Mercury Cougar Base
The 1967 Mercury Cougar Base can use either of the two 14-inch bias-ply primary tire sizes, making wheel setup and existing configuration especially important to confirm. That gives owners a choice between a more restrained 735-14 presentation and the broader styling range available in F70-14, including redline, stripe, and raised white letter looks.
The 1967 Mercury Cougar High Performance Big Eng. uses the F70-14 bias-ply size on a 14-inch rim. That keeps tire selection focused on choosing the right vintage series and sidewall treatment, while also making radial-equivalent comparison more relevant for owners considering a different construction approach.
Bias-Ply to Radial Tire Conversion for the 1967 Mercury Cougar
The 1967 Mercury Cougar has radial-equivalent options for both primary bias-ply sizes. For 735-14, the alternatives are 185R14 as an 80-series metric radial, P195/75R14 as a 75-series P-metric radial, and P205/70R14 as a 70-series P-metric radial. For F70-14, the equivalents are 195R14, P205/75R14, P215/70R14, and 750R14 as a bias-look radial. These options span conventional metric, P-metric, and bias-look formats, with a recommended rim-width range of 4 to 6 inches, and they should be checked against wheel width, overall dimensions, and vehicle clearance before changing construction.

Tire Size & Fitment
What tire size fits a 1967 Mercury Cougar?
A 1967 Mercury Cougar uses either 735-14 or F70-14, both in bias-ply construction on 14-inch rims. The exact size depends on the sub-model and the car’s wheel setup, with the Base model using either size and the High Performance Big Eng. application using F70-14.
That means the first job is confirming which configuration the car actually has before choosing a tire. On a restored or modified Cougar, it is also smart to verify the wheel diameter and width already on the car so the selected tire matches both the intended fitment and the available product range.
What size rim does a 1967 Mercury Cougar use?
The primary tire fitments for the 1967 Mercury Cougar use a 14-inch rim. Both 735-14 and F70-14 are 14-inch bias-ply sizes, so rim diameter stays consistent even though the tire size itself can vary by application.
Rim diameter is only part of the fitment picture, especially on a car that may have changed wheels over time. A 735-14 product can call for a different wheel-width range than an F70-14 product, so measuring the wheels on the car helps narrow the correct choices before comparing brands, series, or sidewall styles.
Do all 1967 Mercury Cougar sub-models use the same tire size?
No. The 1967 Mercury Cougar Base can use either 735-14 or F70-14, while the 1967 Mercury Cougar High Performance Big Eng. uses F70-14. Both are bias-ply 14-inch fitments, but they are not interchangeable as a blanket rule across every covered configuration.
That difference matters because tire selection starts with identifying the exact sub-model and then confirming the wheel setup on the car today. Once that is settled, the choice becomes more specific: whether to stay with a period-style bias-ply tire, consider a radial equivalent, and select the sidewall look that suits the Cougar’s intended appearance.
Bias-Ply & Radial Options
Is F70-14 a bias-ply or radial tire for the 1967 Mercury Cougar?
F70-14 is a bias-ply primary tire size for the 1967 Mercury Cougar. It uses the vintage alphanumeric sizing system rather than a modern radial format, and it appears in period-style bias-ply offerings from Firestone and Goodyear across several series and sidewall treatments.
Owners who want to preserve the original type of construction often stay with an F70-14 bias-ply, especially when appearance is part of the goal. Anyone considering a radial alternative should treat it as an equivalent-size option, then verify wheel width, tire dimensions, and clearance instead of assuming every 14-inch radial choice will suit the car.
What radial tire sizes are equivalent to F70-14?
Radial equivalents for F70-14 include 195R14 as an 80-series metric radial, P205/75R14 as a 75-series P-metric radial, P215/70R14 as a 70-series P-metric radial, and 750R14 as a bias-look radial. These give the 1967 Mercury Cougar owner several ways to compare modern radial sizing to the original bias-ply fitment.
The practical difference is that these options use different sizing conventions and can present the car differently, especially the bias-look radial versus a more modern metric radial. A recommended rim-width range of 4 to 6 inches is associated with these equivalents, and clearance, wheel width, and overall fit should be checked before making the change.
Can I use a bias-look radial on a 1967 Mercury Cougar?
A bias-look radial equivalent is available for the 1967 Mercury Cougar when the primary size is F70-14, and that equivalent is 750R14. It gives owners an option that visually leans toward a traditional tire presentation while still being categorized as a radial rather than a bias-ply tire.
That makes it worth considering when the car’s appearance matters but a radial-format alternative is still on the table. The key is to confirm that the wheel and vehicle setup suit the equivalent size, including rim width and body or steering clearance, because a bias-look radial should be evaluated as an alternative, not assumed to match automatically.
Choosing the Right Tire
What should I consider when choosing a 1967 Mercury Cougar tire?
Start with the exact tire size the car uses, since a 1967 Mercury Cougar may require either 735-14 or F70-14 depending on sub-model and wheel setup. From there, compare construction, rim-width compatibility, sidewall style, brand, tire series, and any load specification tied to the product you are considering.
The right choice depends on how the Cougar will be used and how you want it to look. A restoration-oriented car may lean toward a traditional bias-ply presentation, while a driver may also compare radial equivalents, but either route still calls for matching the tire to the actual wheel dimensions and the car’s present configuration.
What sidewall styles are available for 1967 Mercury Cougar tires?
Sidewall choices for the 1967 Mercury Cougar include blackwall and narrow whitewall in 735-14, plus redline, pin-white-stripe, and RWL in F70-14. That gives the car a wide range of vintage visual treatments, from understated touring style to a more assertive muscle-era presentation.
Sidewall appearance should be matched to the tire size the car actually uses before deciding purely on looks. It is also worth considering the overall restoration theme, since a subtle whitewall creates a very different impression than redline or raised white letters even when the wheel diameter and basic fitment remain the same.
What brands offer tires for the 1967 Mercury Cougar?
BFGoodrich, Firestone, and Goodyear all offer tires for the 1967 Mercury Cougar within its primary fitment sizes. BFGoodrich appears in 735-14 through the Silvertown Classic Bias Ply line, while Firestone and Goodyear cover F70-14 in series such as Wide Oval, Custom Wide Tread, and Speedway Wide Tread.
Brand choice is really part of a larger selection process rather than a ranking exercise. Once the correct size is confirmed, compare which brand offers the sidewall treatment, tire series, rim-width specification, and period-style character that best suits the Cougar’s intended appearance and road use.
Restoration & Appearance
Which tire should I choose for a period-style 1967 Mercury Cougar?
A period-style 1967 Mercury Cougar tire starts with the correct primary size for the car, either 735-14 or F70-14, and then stays within the available bias-ply offerings. That keeps the sizing format and construction aligned with the kind of tire presentation associated with the Cougar’s late-1960s character.
From there, the decision becomes one of visual emphasis. A 735-14 blackwall or narrow whitewall gives a more restrained look, while F70-14 opens the door to redline, pin-white-stripe, or raised white letter treatments. For exact originality, it is wise to compare the car against marque references and restoration documentation before settling on details.
How does tire construction affect the appearance of a restored 1967 Mercury Cougar?
Construction changes the visual character of a restored 1967 Mercury Cougar as much as it changes the technical format of the tire. Bias-ply tires preserve the original-style sizing language and traditional stance associated with the car’s era, while radial equivalents introduce modern sizing conventions and, in some cases, a different overall look.
That is why owners often decide on appearance before they decide on construction. A restoration-oriented Cougar may benefit from staying with a bias-ply tire, while a bias-look radial can be part of the conversation on F70-14 applications. Either way, the final choice should still respect the car’s wheel dimensions and fitment needs.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1967 Mercury Cougar?
Yes. Modifications can affect tire fitment on a 1967 Mercury Cougar even when the nominal tire size sounds correct. Aftermarket wheels, altered wheel width, suspension changes, lowering, or bodywork differences can all change how a 735-14, F70-14, or a radial equivalent sits in the wheel opening.
That is why a modified Cougar should be measured rather than judged by catalog size alone. Checking wheel diameter, wheel width, steering clearance, and fender clearance helps prevent surprises, especially when moving from bias-ply to radial construction or when the car has been restored with components that differ from its earlier setup.
What should I inspect before driving a 1967 Mercury Cougar on new tires?
Before driving a 1967 Mercury Cougar on new tires, inspect the wheels for the correct diameter and usable width, then confirm that each tire is mounted in the proper size for the car’s configuration. It is also smart to check inflation, lug torque, valve stems, and general clearance around suspension, steering, and fender areas.
A collector car deserves a broader once-over before road use, especially if it has been parked for long periods. Look for worn steering components, tired suspension parts, brake issues, and any signs that the previous tires rubbed or lost air, since those clues can point to a fitment or maintenance issue beyond the tire itself.
How should tires on a collector 1967 Mercury Cougar be maintained?
Tires on a collector 1967 Mercury Cougar should be inspected regularly for pressure loss, cracking, bulges, cuts, uneven wear, and any changes in ride feel. Low-mileage storage does not eliminate aging, so even a car that is driven sparingly still benefits from routine condition checks before short trips and longer drives.
Storage conditions matter as much as mileage on an older vehicle. Keeping the Cougar away from prolonged sunlight, excess heat, moisture, and ozone sources helps protect the tires, while periodic movement of the car and prompt attention to air loss or visible damage can prevent a small issue from becoming a road-use problem.
