1964 Mercury Tire Fitment Guide

1964 Mercury vehicles use five tire sizes across three model groups: 800-14 for full-size Mercury applications and some wagons, 6.50-14 for certain Comet applications, 700-14 for Comet, 750-14 for Comet, and 850-14 for wagons. Every one of those sizes fits a 14-inch wheel, but the width and intended vehicle application change from one model family to another. Where product fitment details are available, 700-14 fits 5.00 to 5.50-inch rims, 750-14 fits 5.00 to 5.50-inch rims, 800-14 fits 5.00 to 6.00-inch rims, and 850-14 fits 5.50 to 6.00-inch rims.

That means a 1964 Mercury buyer should identify the model family before doing anything else. A Comet, a wagon, and a full-size Mercury may all use 14-inch wheels, but they are not automatically interchangeable once section width, load needs, and visual proportions are considered. If your car has been restored or modified over the years, check the size stamped on the current tire and confirm the actual wheel width before choosing among the period-correct bias-ply options.

On a 1964 Mercury, 700-14 is a numeric bias-ply tire size. The 7.00 portion is the nominal section-width designation used in period sizing, and the 14 identifies the wheel diameter in inches. For Mercury applications here, 700-14 appears on the Comet and is available in bias-ply construction only. In currently available versions, it carries a 1360-pound load rating at 32 psi and fits rims from 5.00 to 5.50 inches wide.

That older numeric format can look unusual if you are used to modern metric sizing, but it is normal for early- and mid-sixties American cars. The practical takeaway is that 700-14 is not simply another way of writing a modern radial size; it is part of the original bias-ply fitment language of the era. If your Comet wears 700-14 tires today, matching that code keeps the wheel diameter and period-style sizing approach in the right family.

No, 1964 Mercury models do not all use the same tire size. Full-size Mercury applications center on 800-14, the Comet uses 6.50-14, 700-14, or 750-14 depending on application, and wagons use either 800-14 or 850-14. All of those are bias-ply 14-inch sizes, but the section widths and model assignments differ enough that year and make alone are not a complete fitment answer.

That model-to-model variation matters because tire choice on a 1964 Mercury is tied to the body family, not just the badge on the hood. If you are shopping for a wagon, a Comet size should not be treated as a default substitute, and the reverse is equally true. Checking the exact model and verifying the wheel width helps you stay closer to the proportions, load capacity, and appearance the car was designed around.

1964 Mercury tires are available in several period-appropriate sidewall styles depending on size. 800-14 comes in blackwall, narrow whitewall, and wide whitewall form. 700-14 offers blackwall and narrow whitewall choices, while 750-14 adds the broadest styling spread with narrow whitewall, wide whitewall, and redline options. 850-14 is offered in narrow whitewall and wide whitewall form for wagon applications.

Sidewall choice changes the whole personality of a mid-sixties Mercury even when the tire size stays the same. Full-size cars and wagons often look especially natural with whitewalls, while a blackwall or redline can shift the look toward a more understated or period street-driven presentation. If your goal is authenticity for a particular car, old photos, sales literature, and marque specialists can help you narrow the sidewall style that best matches your Mercury’s original market position.

1964 Mercury tires are available from BFGoodrich, Universal Vintage Tire, US Royal, and Coker Classic, depending on size. BFGoodrich covers 700-14, 800-14, 750-14, and 850-14. Universal Vintage Tire appears in 800-14, while US Royal and Coker Classic appear in 750-14. Every available fitment in this Mercury group remains in bias-ply construction, which suits the period of the car.

Brand choice on a 1964 Mercury usually comes down to the exact size you need and the sidewall look you want rather than a basic construction decision, since these are all bias-ply offerings. The widest brand spread appears in 750-14 for Comet owners, while some other sizes are much more narrowly focused. Once you know the correct size, comparing brand-specific styling cues and load figures is the most useful next step.

For a 1964 Mercury using 750-14 tires, BFGoodrich and US Royal share the same basic bias-ply size and the same 14-inch rim diameter, but they differ in load rating, styling, and weight. BFGoodrich 750-14 examples carry a 1580-pound load rating at 32 psi and appear in narrow whitewall form at 23 pounds. US Royal 750-14 versions carry a 1500-pound load rating at 32 psi, weigh 22 pounds, and are available in narrow whitewall and redline styles. Both fit 5.00 to 5.50-inch rims.

That makes the choice less about fitment and more about the character you want from the finished car. A BFGoodrich 750-14 may appeal to owners focused on that familiar American full-line bias-ply look, while a US Royal 750-14 opens the door to redline styling that suits certain period-custom or sporty presentations. Because the wheel fit is shared, the deciding factors are usually sidewall appearance and how closely the load spec matches your intended use.

Rim-width requirements for 1964 Mercury tires vary by size even though all of them fit 14-inch wheels. 700-14 and 750-14 fit 5.00 to 5.50-inch rims. 800-14 fits 5.00 to 6.00-inch rims, and 850-14 fits 5.50 to 6.00-inch rims. Those ranges matter because a tire that matches the wheel diameter can still sit incorrectly if the wheel is too narrow or too wide for the casing.

That is especially important on cars that may have had wheels swapped at some point in their lives. Before choosing a 1964 Mercury tire, measure or verify the actual wheel width rather than assuming every factory-looking 14-inch wheel is the same. Staying within the correct rim-width range helps the tire maintain the intended profile, tread shape, and road behavior for a proper vintage fit.

1964 Mercury tire products in these sizes do not carry tube-type or tubeless markings in the size description, so tube choice should be confirmed against the specific tire’s sidewall marking and the wheel you plan to use. That matters most on original-style collector wheels, where rim condition and bead-seat design can influence whether tube use is appropriate. The sizes themselves—700-14, 750-14, 800-14, and 850-14—do not by themselves settle the question.

The practical approach is to inspect the wheel first and then match the tire setup to the wheel’s condition and intended use. Restored original wheels, older riveted wheels, or wheels with pitting sometimes call for more caution than newly refurbished rims. If you are uncertain, treat tube selection as a setup decision rather than assuming every bias-ply tire for a 1964 Mercury should be handled the same way.

Original 1964 Mercury wheels can only be shared across tire sizes when both the wheel diameter and the wheel width line up with the tire’s requirements. Every size in this Mercury range fits a 14-inch wheel, so diameter is consistent across the lineup. The limiting factor is width: a 700-14 or 750-14 wants a 5.00 to 5.50-inch rim, 800-14 works on 5.00 to 6.00 inches, and 850-14 needs 5.50 to 6.00 inches.

That means some 14-inch Mercury wheels may accept more than one size, while others may not. A wagon wheel suited to 850-14 is not automatically the same as a Comet wheel used with 700-14, even though both have the same bead-seat diameter. Measure the wheel before swapping sizes, especially if the car has mixed parts from different Mercury or Ford family vehicles.

A stored 1964 Mercury should be kept out of direct sunlight, away from electric motors or other ozone-producing equipment, and on a clean, dry surface. Bias-ply tires like the ones used across the 1964 Mercury range are more prone to temporary flat-spotting during long static storage than many modern radials, so periodic movement helps. If the car will sit for an extended period, keeping the tires properly inflated and rolling the car occasionally reduces stress on one section of the casing.

Owners who store a 1964 Mercury for a season or longer often benefit from using tire cradles or stands, especially if the car will not be driven regularly. That protects both the tire shape and the suspension from carrying the same load in the same position month after month. After storage, inspect the sidewalls and tread carefully before driving, since a collector car can age out its tires long before it wears them out.

Tires on a 1964 Mercury usually age out before they wear out, because collector cars tend to see limited annual mileage. A sensible rule is to inspect them closely once they reach five to seven years of age and to give serious replacement consideration around the ten-year mark regardless of tread depth. The DOT date code on the tire identifies age, and that date matters more than odometer mileage for a vintage Mercury that spends much of its life parked or driven occasionally.

Bias-ply tires can still look presentable while internal aging, hardening, or sidewall cracking begins to affect reliability. That is why appearance alone should not be the deciding factor on a 1964 Mercury that still wears old reproduction tires. If the car is used for tours, highway miles, or family cruising rather than static display, age-based replacement becomes even more important.

Tires on a 1964 Mercury should be inspected before every drive, and they deserve a more thorough check before any extended outing. Look for sidewall cracking, bulges, cuts, uneven tread wear, signs of pressure loss, and any change in the way the car sits after being parked. On a vintage car, inspection should include the spare as well, since a decades-old spare can be unusable even if it has never touched the road.

A quick pre-drive walkaround catches many of the problems that strand collector cars. If your 1964 Mercury has been sitting for weeks or months, the first miles after storage are when flat spots, aging rubber, or pressure issues tend to show up. Building tire inspection into your normal routine is one of the easiest ways to protect both the car and the trip.

The 1964 Mercury Comet used bias-ply tires, which was standard American practice in that period. Comet applications here fall into the 6.50-14, 700-14, and 750-14 size family, all on 14-inch wheels. That range reflects how a compact Mercury could vary by body style or equipment while still staying within period-correct bias-ply construction. No single original-equipment brand should be assumed without checking the car’s market history and supporting factory literature.

For a restoration-minded owner, the key point is to stay within the right construction type, size family, and sidewall presentation for the specific Comet being restored. A marque club, period brochure, or unrestored survivor can help narrow whether your car is best represented by a blackwall, whitewall, or another era-appropriate sidewall treatment. Once the visual target is clear, the correct Comet size becomes much easier to choose.

Correct tire fitment absolutely matters when a 1964 Mercury is judged for authenticity. Size, construction type, and sidewall style all affect whether the car looks right for its year and model family. On a mid-sixties Mercury, a tire that is visibly too wide, carries the wrong sidewall treatment, or belongs to a different model group can stand out immediately. Since all of the proper fitments here are bias-ply, staying in that construction family is usually part of preserving an accurate presentation.

Show standards can vary between local cruise nights, marque events, and concours-level judging, so the level of scrutiny depends on where the car will appear. A redline 750-14 may be exciting on the right Comet-style build, but it would not suit every 1964 Mercury equally. If the car is being restored for formal judging, event rules and Mercury specialists are the best way to confirm how strict the tire expectations will be.

For a 1964 Mercury using 800-14 tires, BFGoodrich and Universal Vintage Tire share the same basic bias-ply size and 14-inch fitment, but they differ in styling detail and available specification depth. BFGoodrich offers 800-14 in blackwall, narrow whitewall, and wide whitewall versions, with a 1620-pound load rating at 32 psi on the BFGoodrich examples and a 5.00 to 6.00-inch rim-width range. Universal Vintage Tire appears in 800-14 with a wide whitewall style and a 24-pound tire weight.

That means the choice is often driven by the exact look you want on the car. A full-size Mercury restored to a restrained factory appearance may lean toward blackwall or narrow whitewall, while a bright, upscale presentation often favors a wider whitewall. Since both live in the same 800-14 bias-ply family, wheel compatibility starts from the same 14-inch diameter and then narrows around your desired finish and rim-width match.

1964 Mercury tires in these fitments are bias-ply collector tires, and no speed-rating letters appear in the available size markings here. That means highway suitability should be judged conservatively and in the context of the car itself, not as a modern high-speed performance application. A well-sorted 1964 Mercury with fresh, correctly sized bias-ply tires can be enjoyable on normal roads, but the car’s steering feel, braking system, suspension design, and age all play a major role in how relaxed it will feel at sustained speed.

The most practical approach is to treat a 1964 Mercury like the vintage car it is. Keep speeds appropriate to the road, maintain correct inflation, and avoid assuming that modern traffic pace erases the limitations of a mid-sixties chassis. If long highway trips are part of the plan, make sure the entire car is ready for that use and not just the tires alone.

Available load figures for 1964 Mercury tires are tied to 32 psi on the product specifications shown for several sizes. 700-14 carries 1360 pounds at 32 psi, 750-14 ranges from 1500 to 1580 pounds at 32 psi, 800-14 carries 1620 pounds at 32 psi, and 850-14 carries 1740 pounds at 32 psi. Those numbers describe the tire’s rated load at that pressure, but they are not automatically the same as the factory inflation recommendation for every Mercury model.

Use the owner’s manual or factory service literature as the starting point for the vehicle’s intended operating pressure, then compare that with the tire manufacturer’s rating information for the exact size you choose. A Comet and a wagon should not be treated identically simply because both use 14-inch wheels. Keeping the pressure matched to the tire and the car helps preserve ride quality, tread shape, and safe load carrying.

Before a longer drive in a 1964 Mercury, inspect each tire for sidewall cracking, cuts, bulges, exposed cords, irregular wear, and proper inflation. Check that the spare is usable, that the valve stems are in good condition, and that each tire is the correct size for the model family on the car. On a vintage Mercury, tire readiness is only one part of the picture, but it is one of the easiest places to catch a preventable roadside problem before the trip starts.

Longer drives also put more heat and sustained load into the tires than a short neighborhood loop, so old rubber problems tend to reveal themselves more quickly. If the car has been sitting, take a short shakedown drive first and recheck pressures afterward. A 1964 Mercury that is prepared methodically is far more enjoyable than one that heads out with aged tires and unanswered setup questions.
