1967 Mercury Tire Fitment Guide

1967 Mercury vehicles use five sizes across four model groups: 735-14 for Comet and Cougar, 775-14 for Comet, F70-14 for Comet and Cougar, 8.25-15 for full-size Mercury models, and 855-15 for full-size Mercury models and Mercury Wagons. The 14-inch sizes mount on 14-inch wheels, while the 15-inch sizes mount on 15-inch wheels. Rim-width guidance appears for 735-14 at 5.00 to 5.50 inches, for 775-14 at 5.00 to 6.00 or 5.50 to 6.00 inches depending on the tire, for F70-14 at 6.00 to 7.00 inches, and for 855-15 at 6.00 to 6.50 inches.

That spread means a 1967 Mercury owner should identify the model first, then the wheel diameter, and only then choose the tire. Comet and Cougar buyers stay within the 14-inch family, while full-size Mercury and wagon owners move into 15-inch territory. Once the basic size is confirmed, sidewall styling becomes the next meaningful choice, especially on cars where narrow whitewalls, redlines, or raised white letters can change the visual character of the finished restoration.

On a 1967 Mercury, 735-14 is a numeric bias-ply tire size. The 7.35 figure is the nominal section width in inches, written without a decimal-leading convention common to the period, and the 14 identifies the wheel diameter in inches. In the 1967 Mercury range, this size appears on certain Comet and Cougar applications and fits 14-inch wheels. BFGoodrich offers it in both blackwall and narrow whitewall form, with a 5.00 to 5.50 inch rim-width range and a maximum load rating of 1,360 pounds at 32 psi.

For a buyer, that means 735-14 is less about decoding modern metric language and more about understanding a period sizing system. It is a traditional 1960s bias-ply fitment, so the choice usually turns on whether you want a plain blackwall presentation or a cleaner narrow-whitewall look. If your car already has wheels on it, confirming that they are 14-inch rims and fall within the proper width range is the most useful check before moving forward.

On a 1967 Mercury, F70-14 is an alphanumeric bias-ply size rather than a modern radial or metric one. The letter F identifies a size class in the alphanumeric system, the 70 is part of that period designation, and the 14 is the wheel diameter in inches. Within the Mercury lineup, F70-14 fits certain Comet and Cougar models and is built around a 14-inch wheel with a 6.00 to 7.00 inch rim-width range. Firestone and Goodyear both offer it, with sidewall options that include pin white stripe, redline, and raised white letters.

That matters because F70-14 often signals a more performance-oriented late-1960s visual theme than a plain numeric bias-ply size. On a Cougar or Comet with a sportier presentation, it can look more era-appropriate than a standard narrow whitewall. The key is to treat the alphanumeric code as its own fitment family rather than assuming it is interchangeable with every other 14-inch Mercury size without checking the wheel width and the exact model application.

No. 1967 Mercury models do not all use the same tire size. Comet uses 735-14, 775-14, and F70-14 depending on application; Cougar uses 735-14 and F70-14; full-size Mercury models use 8.25-15 and 855-15; and Mercury Wagons use 855-15. That split also separates the lineup by wheel diameter, with compact and pony-car models on 14-inch sizes and larger Mercury cars and wagons on 15-inch sizes.

The practical takeaway is simple: year and make are only the starting point for 1967 Mercury tire selection. If you are working with a Comet or Cougar, you should stay within the 14-inch fitments that suit those platforms. If you own a full-size Mercury or a wagon, moving to the correct 15-inch family is just as important as choosing the right sidewall treatment for the car's original character or intended presentation.

1967 Mercury tires cover several sidewall treatments depending on size. The 735-14 size comes in blackwall and narrow whitewall. The 775-14 size appears in narrow whitewall and redline. F70-14 expands the range further with pin white stripe, redline, and raised white letter styling, while 855-15 stays in the narrow whitewall family with more than one whitewall width. Those choices line up well with Mercury's mix of compact, sporty, and full-size cars during the 1967 model year.

A buyer choosing for authenticity should usually let the model's character lead the way. Full-size Mercury cars and wagons generally look most at home with narrow whitewalls, while sportier Comet and Cougar applications can justify redline or raised white letter treatments when the car is built around that late-1960s performance image. If the goal is judged originality, confirm the exact sidewall expectation through factory literature or a Mercury marque specialist before making the final call.

1967 Mercury fitments are covered by several well-known vintage tire brands. BFGoodrich appears in 735-14, 775-14, and 855-15. Firestone appears in 775-14 and F70-14. US Royal appears in 775-14, and Goodyear appears in F70-14. All of the tire sizes and products here are bias-ply, which suits the period nature of the 1967 Mercury range.

Brand choice on a collector Mercury often comes down to the look you want as much as the basic fitment. Some owners prioritize a traditional blackwall or whitewall presentation, while others want the stronger visual signature of a Firestone Wide Oval or Goodyear-style performance sidewall. Once the correct size is confirmed for your model, compare brands within that size by sidewall style, rim-width compatibility, and the overall period theme of your car.

For a 1967 Mercury using F70-14, Firestone Wide Oval and Goodyear Custom Wide Tread share the same basic bias-ply size and both fit 14-inch wheels with a 6.00 to 7.00 inch rim-width range. Firestone Wide Oval appears in pin white stripe, redline, and raised white letter versions, each carrying a 1,500-pound maximum load at 32 psi and a 24-pound tire weight. Goodyear Custom Wide Tread appears in raised white letter form, with a 1,500-pound maximum load at 32 psi and a 25-pound tire weight.

That makes the choice more about period presentation than raw fitment difference. Firestone offers broader sidewall variety if you are matching a specific visual style, while Goodyear gives a distinct raised-white-letter muscle-era look within the same overall F70-14 footprint. Either way, the wheel should be confirmed within the proper width range so the tire sits correctly and preserves the intended stance of the Mercury application.

Rim-width guidance for 1967 Mercury tires varies by size. The 735-14 uses a 5.00 to 5.50 inch rim. The 775-14 generally falls in the 5.00 to 6.00 inch or 5.50 to 6.00 inch range depending on the tire. F70-14 uses a wider 6.00 to 7.00 inch rim, and 855-15 uses a 6.00 to 6.50 inch rim. Each of those ranges reflects the tire itself, not a blanket rule for every Mercury wheel from the year.

That is why wheel verification matters before final selection, especially on cars that may have changed hands, been restored, or received replacement wheels over the decades. A 14-inch rim can still be the wrong width for a particular 14-inch tire family. Matching the tire to both the correct wheel diameter and the proper rim-width range helps preserve the tire's shape, sidewall posture, and overall visual proportion on a 1967 Mercury.

Inner-tube status is not called out uniformly across the 1967 Mercury product range, so tube requirements should be confirmed tire by tire rather than assumed for every size. That is especially important with vintage bias-ply applications, because some collector-car wheels and reproduction tires are used in tube-type arrangements while others may be paired differently depending on wheel condition and design. No size here carries a universal tube instruction that should be applied across the entire year and make.

The safest approach is to inspect the actual wheel and then check the sidewall marking and manufacturer guidance for the exact tire you are considering. Original-style steel wheels, restored wheels, and older rims can all influence whether a tube is appropriate. If your 1967 Mercury will be driven regularly, it is also wise to evaluate the valve stems, rim condition, and spare tire setup at the same time rather than treating tube choice as a separate issue.

Original 1967 Mercury wheels can only be used with the tire sizes that match their wheel diameter and width range. The 14-inch tires used on Comet and Cougar applications are not interchangeable with the 15-inch tires used on full-size Mercury cars and wagons. Even within the 14-inch family, a 735-14 calls for a narrower rim than an F70-14, so wheel width matters as much as wheel diameter.

That means an owner should avoid treating every factory Mercury wheel from 1967 as interchangeable simply because it looks era-correct. A Comet wheel may not suit an F70-14 if the rim is too narrow, and a full-size Mercury wheel moves into a different diameter family altogether. Measuring the actual wheel and matching it to the tire's approved width range is the cleanest way to avoid fitment surprises.

A 1967 Mercury should be stored in a cool, dry, dark space away from direct sunlight, electric motors, welders, battery chargers, and other ozone sources that can age rubber. Tire pressures should be kept up during storage, and the car should either be moved periodically or set in a way that reduces long-term static loading. Because every size here is bias-ply, extended sitting can encourage temporary flat-spotting more readily than many later radial designs.

For collector cars that spend weeks or months parked, a clean concrete floor, tire cradles, or periodic repositioning can all help reduce stress on the carcass. If your 1967 Mercury is a heavier full-size car or wagon, the need for proper storage habits becomes even more important. Good storage practice protects both the visual finish of the sidewall and the tire's behavior when the car goes back on the road.

On a 1967 Mercury, tire life should be judged more by age and condition than by mileage, because many collector cars are driven lightly. A sensible rule is to begin evaluating tires closely once they are around five to seven years old and to consider replacement as they approach ten years, even if tread still looks good. The DOT date code on the tire sidewall helps establish age, while cracking, hardening, separation, or persistent air loss are stronger warning signs than tread depth alone.

That approach matters because an older bias-ply tire can look presentable on a hobby car while still being past its best service life. If your 1967 Mercury is used for local cruises only, age still matters. If it sees highway travel or long-distance touring, replacing aging tires before they become visibly distressed is usually the wiser path for preserving both the car and the driving experience.

Tires on a 1967 Mercury should be checked before every drive and inspected more thoroughly before any longer outing. The key points are inflation pressure, sidewall cracking, tread wear, cuts, bulges, and any sign that the tire has begun to lose its shape after sitting. On a collector car, the spare deserves the same attention, since it may be just as old as the four tires on the ground even if it has never been used.

A more complete inspection every few months is a good routine even if the Mercury is only driven occasionally. That is also the right time to look at valve stems, wheel condition, and any vibration or pull that may have developed since the last drive. Catching age-related problems early matters on 1960s vehicles because their braking and suspension systems were designed around the standards of their time, not around neglected tires.

A 1967 Mercury Comet originally belonged to the bias-ply era, and the fitments here reflect that with 735-14, 775-14, and F70-14 all appearing as bias-ply sizes tied to Comet applications. The exact size depended on the specific Comet version and how it was equipped, but the larger point is that a period-correct Comet restoration should begin within those bias-ply families rather than jumping straight to a later radial format. No original-equipment brand should be assumed without model-specific factory references.

That makes the Comet a good example of why restoration fitment should be narrowed by model, wheel, and intended presentation. A plain trim-focused car may call for a different visual approach than a sportier Comet with stronger 1960s muscle-era cues. If authenticity matters, verify the exact sidewall style and size through factory literature, dealer material, or a Mercury marque club before finalizing the tire choice.

Correct tire fitment absolutely matters when showing a 1967 Mercury. Judges and knowledgeable enthusiasts often notice whether the size, construction type, and sidewall treatment match the character and era of the car. A full-size Mercury wearing an obviously performance-oriented raised white letter tire, or a sporty Cougar wearing the wrong whitewall treatment, can look out of step even if the tire physically fits the wheel. Construction also matters, since 1967 Mercury models were built in the bias-ply era.

The importance of that detail depends on your goal. At a casual local show, a tasteful period-style tire may be enough. At a stricter concours or marque event, subtle items such as whitewall width, redline presence, and correct size family can affect how authentic the car appears. Event-specific standards vary, so owners chasing top-tier originality should compare their choice against judging manuals, period photos, and Mercury club guidance.

For a 1967 Mercury using 855-15, BFGoodrich offers more than one narrow whitewall presentation in the same basic bias-ply size. One version uses a 1.00-inch whitewall and another uses a 5/8-inch whitewall. Both share the same 15-inch rim diameter, the same 6.00 to 6.50 inch rim-width range, and the same 1,710-pound maximum load at 32 psi. The difference is visual rather than structural, making this a style choice within the same fitment family.

That visual distinction can matter a great deal on a big 1967 Mercury or a wagon, where sidewall treatment contributes strongly to the car's stance and era feel. A slightly broader whitewall can give the car a more upscale, formal look, while a narrower stripe can read a little cleaner and later in character. For restoration work, compare the whitewall width against period photos or original sales literature so the finished look matches the car's intended presentation.

A properly chosen, properly inflated 1967 Mercury tire can be suitable for normal highway use, but the real answer depends on the exact tire, its age, and the condition of the car around it. The sizes here are all bias-ply, and no speed-rating letters are called out in the size markings for these products. Load figures include 1,360 pounds at 32 psi for 735-14, 1,500 pounds at 32 psi for F70-14, 1,580 pounds at 32 psi for many 775-14 options, and 1,710 pounds at 32 psi for 855-15.

On a 1967 Mercury, the vehicle's own era-correct brakes, steering, suspension, and overall condition are often just as important as the tire itself once you are driving at modern speeds. Bias-ply tires also have a different feel from later radials, especially in tracking and response. Before longer highway use, make sure the tires are fresh, the pressures are right, and the car is mechanically ready for sustained road speeds.

Inflation pressure on a 1967 Mercury should begin with the factory recommendation for the specific model and tire size, then be checked against the tire's own rated load-and-pressure information. Several sizes here carry maximum load ratings at 32 psi: 735-14 at 1,360 pounds, many 775-14 options at 1,580 pounds, F70-14 at 1,500 pounds, and 855-15 at 1,710 pounds. Those figures are maximum-rated load points for the tire and should not be treated automatically as the day-to-day pressure your Mercury requires.

That distinction matters because operating pressure on a classic car is part of overall ride and handling balance, not just a number printed next to maximum load. A compact Comet, a Cougar, and a full-size Mercury will not necessarily want the same pressure behavior even when they share an era and a construction type. Use the owner's manual or factory placard as your baseline, then confirm you remain within the tire maker's limits for the exact size you run.

Before a longer drive in a 1967 Mercury, inspect all four tires and the spare for cracking, cuts, bulges, uneven wear, proper inflation, and any sign of age-related hardening. Confirm that each tire matches the model's correct size family and that the wheels suit the tire's diameter and width requirements. If the car has been parked for an extended time, pay close attention to temporary flat spots, air retention, and the condition of the valve stems.

Tires are only one part of the preparation, but they are one of the most visible warning points on an older car. A Mercury that tracks well around town can still reveal problems when speeds rise and the drive gets longer. It is wise to pair the tire inspection with a broader check of brakes, steering, suspension, fluids, and lights so the car is ready as a complete system rather than just rolling on fresh-looking rubber.
