Ford Mercury Tires

Ford Mercury uses three listed tire sizes across 1939 through 1942. The 1939 Ford Mercury uses 600-16 on a 16-inch rim, the 1940 Ford Mercury is listed with either 600-16 or 650-16 on 16-inch rims, the 1941 Ford Mercury uses 650-16 on a 16-inch rim, and the 1942 Ford Mercury uses 6.50-15 on a 15-inch rim. All available products in these applications are bias-ply tires.

That means the correct choice starts with the car’s exact year and wheel diameter, then narrows to the listed size for that combination. A 1940 Ford Mercury needs extra attention because both 600-16 and 650-16 appear in the fitment range, so the actual wheel and the car’s configuration should be checked before selecting a tire.

On a Ford Mercury, 600-16 is a numeric bias-ply size. The 600 portion indicates a nominal 6.00-inch section width, while the 16 indicates a 16-inch rim diameter. Products in this size are built around 16-inch wheels, with many examples suited to 4.00 to 4.50 inch rim widths.

That size is associated with 1939 Ford Mercury and also appears on some 1940 applications, so it should not be chosen by year alone when a 1940 car is involved. If the car still has its original-style wheels, confirm the wheel diameter and compare the existing tire or wheel markings before moving to sidewall style or brand preference.

The 1940 Ford Mercury is listed with both 600-16 and 650-16, and both are 16-inch rim applications. Because the rim diameter stays the same, the split is not a 15-inch versus 16-inch issue; it is a within-year fitment difference tied to configuration rather than wheel diameter. The larger size adds section width while remaining on the same basic rim diameter family.

That makes 1940 the year that deserves the most careful checking before a tire is chosen. Compare the tire size currently on the car, inspect the wheel itself, and verify against original paperwork or a Mercury marque specialist if the car has been restored, modified, or fitted with replacement wheels at some point in its life.

Ford Mercury uses 16-inch rims in 1939, 1940, and 1941, then shifts to 15-inch rims in 1942. The 600-16 and 650-16 sizes are both 16-inch applications, while 6.50-15 is a 15-inch application. That year break is the clearest fitment change in the whole range.

A restorer should confirm the actual wheel on the car before matching a tire to the year. Cars that have been swapped, upgraded, or assembled from mixed parts can easily carry a different wheel than expected, and selecting a tire by year alone can create an immediate mismatch even when the size looks generally correct at first glance.

A 1940 Ford Mercury is the one year in this range with two listed sizes: 600-16 and 650-16. Both fit 16-inch rims, so the question is not wheel diameter alone but which specific setup the car carries. The safest approach is to identify the existing wheel and compare the car’s present tire size, wheel markings, and restoration records.

Once the correct size family is confirmed, then it makes sense to choose among blackwall, wide whitewall, or double-whitewall options according to the car’s intended appearance. That sequence matters, because sidewall style is a cosmetic decision, while selecting between 600-16 and 650-16 is a fitment decision that affects the car’s stance and proper installation.

Ford Mercury tires in the listed sizes are available in blackwall, wide whitewall, and double-whitewall forms. The broadest variety appears in 600-16, where all three sidewall styles are represented, while 650-16 includes blackwall and wide whitewall choices. Those options give restorers room to match factory-style appearance or a period custom look.

For a more restrained original presentation, blackwall is usually the simplest visual choice, while wide whitewalls suit many prewar and early postwar restoration themes. Double-whitewall offerings are more specialized and should be chosen with the car’s overall style in mind, especially if the goal is authenticity rather than a later personalized presentation.

The listed Ford Mercury tire brands include BFGoodrich, Coker Classic, Avon, Firestone, Ford Script, Excelsior, Lester, Goodyear, STA, Garfield, Camac, and Tornel. Not every brand appears in every size, and some brands focus more on passenger-style bias-ply offerings while others appear in military or truck-oriented tread families. The broadest brand spread is found in the 16-inch sizes.

That variety lets a buyer choose not only the correct size, but also the visual character and tread style that best fits the car’s purpose. A concours-oriented restoration may lean toward a period-style passenger tire and sidewall treatment, while a utility or specialty build based on similar wheel sizing may point toward a more rugged tread family.

Ford Mercury fitments appear across a wide range of tire series, including Silvertown Classic Bias Ply, Coker Classic Bias Ply, Firestone Classic Bias Ply, Ford Script, Excelsior Bias Ply, Lester Classic Bias Ply, Deluxe All-Weather, Tourist Crossply, Turbospeed Mk4, Military NDT, Firestone Classic Military, NATO CJ110, Transport, Super Traxion, Transport Highway, Tornel Classic Truck, and Firestone Classic Truck. Some are passenger-car bias-ply designs, while others are military, commercial, or truck-oriented patterns built around the same rim diameter.

The practical difference is in appearance and intended use rather than basic year fitment alone. A restored passenger Ford Mercury usually calls for a passenger-style bias-ply series with an era-correct sidewall, while NDT, knobby, highway, or transport series are better understood as specialized tread options that suit utility-focused applications rather than a standard passenger-car presentation.

A Ford Mercury stored on fitted tires should be kept in a cool, dry, dark space away from direct sunlight, ozone sources, and large temperature swings. Clean floors, proper inflation, and protection from petroleum products all help preserve the casing and sidewalls of collector tires. Bias-ply tires especially benefit from stable conditions because they often spend long periods carrying weight without regular heat cycles from driving.

If the car will sit for extended periods, move it occasionally to avoid creating prolonged flat spotting in one position. Many owners also reduce stress by using jack stands correctly placed under the chassis or suspension while keeping the tires lightly loaded, but the support method should suit the vehicle’s frame design and restoration condition.

Tires on a Ford Mercury should be visually inspected before every drive and given a more thorough examination several times each season, even if the car sees limited mileage. Check inflation, tread surface, sidewall condition, valve stems, tube-related air retention, and any signs of cracking, bulging, impact damage, or irregular wear. On an older collector car, tire condition can change from age and storage as much as from road miles.

A practical routine is to inspect the tires whenever the car is washed, rotated, or prepared for an event. Pair that inspection with a look at wheel fasteners, brake condition, and steering play, since many tire complaints on antique and classic cars are actually the first visible sign of a broader chassis or alignment issue.

Ford Mercury tires should be replaced when age, cracking, casing fatigue, impact damage, repeated air loss, or visible structural issues appear, even if the tread still looks usable. Collector-car tires often age out before they wear out because the car is driven infrequently and spends more time parked than in service. Bias-ply tires can look presentable long after the rubber and internal structure have begun to decline.

That is why replacement decisions should be made by condition, age, and intended use rather than tread depth alone. A show-only car may tolerate older tires differently than a car expected to cover road miles, but once deterioration becomes visible, the prudent move is to retire the tire and have the wheel, tube, and flap arrangement inspected at the same time.

Ford Mercury original-type sizing in this range centers on 600-16 for 1939, 600-16 or 650-16 for 1940, 650-16 for 1941, and 6.50-15 for 1942. The available tire families include several passenger-car bias-ply series as well as more specialized tread lines. That means the correct original-style choice depends on the specific year and the way the individual car was equipped.

For restoration work, size should be established first and cosmetic details second. Once the car’s correct size is confirmed, sidewall treatment and series can be chosen to match the restoration goal, and original literature or Mercury club guidance can help narrow whether a plain blackwall or whitewall presentation better suits that particular car.

Correct tire fitment can absolutely affect how a Ford Mercury is judged and how convincingly it presents as a restoration. Size, rim diameter, sidewall style, and overall period appearance all contribute to whether the car looks properly sorted for its year. Even a well-restored car can appear off if the tire width, whitewall treatment, or wheel diameter does not align with the intended era and configuration.

That matters both for formal judging and for buyer confidence when the car is offered for sale. Owners pursuing authenticity usually benefit from comparing their choice against marque club references, period photographs, and restoration standards so the final selection supports the car’s historical character rather than merely filling the wheel openings.

Ford Mercury restoration tires are available in blackwall, wide whitewall, and in some 600-16 offerings, double-whitewall form. Blackwall gives the most restrained period look, while wide whitewall is strongly associated with upscale late-1930s and early-1940s American passenger-car presentation. Double-whitewall is a more specialized visual choice and should be matched carefully to the car’s intended style.

The right answer depends on whether the goal is factory-style restoration, a dealer-era accessory look, or a later customized presentation. Once the correct size is established, the sidewall treatment should be chosen to match the standard of restoration being pursued, because whitewall width and overall visual proportion make a noticeable difference on a Mercury’s stance and character.

A properly selected and properly maintained tire can be suitable for public-road use on a Ford Mercury, but the tire has to be matched to the correct rim diameter and year-specific size first. These fitments are bias-ply applications, so they deliver a period driving feel rather than the behavior of a modern radial touring tire. Condition, age, inflation, wheel integrity, and the car’s mechanical state matter just as much as the tire size itself.

Road use should be approached with the expectations appropriate to an early-1940s automobile. Even with fresh tires, the driver should allow for longer stopping distances, more steering correction, and a slower pace than in a modern car, while making sure the brake system, steering components, and suspension have been inspected to the same standard as the tires.

Before driving a Ford Mercury, check tire inflation, visible sidewall condition, tread condition, valve stems, wheel fasteners, and any sign that a tube-type assembly has lost air. Also inspect for rubbing, uneven wear, or a mismatch between the tire size and the wheel fitted to the car. On a collector vehicle, those quick checks can catch problems that develop slowly in storage.

A short pre-drive routine should also include brakes, steering play, fluid leaks, and the general condition of the wheels themselves. Because the Mercury range here includes both 16-inch and 15-inch applications, verifying that the mounted tire size actually matches the wheel on the car is one of the most important checks before putting any road miles on it.

A Ford Mercury running original-type bias-ply tires should be driven at moderate speeds that suit the tire design, the car’s mechanical condition, and the realities of prewar chassis behavior. These tires are built to preserve period-correct driving character, not to duplicate the tracking, heat tolerance, and emergency-response behavior of a modern performance radial. Safe speed is therefore determined by the entire vehicle system, not by tread depth alone.

In practice, owners usually get the best results by driving smoothly, avoiding sustained high-speed use, and leaving extra room for braking and lane changes. If the car is freshly restored or has sat for a long period, begin with short local drives and recheck tire pressure and temperature afterward so the whole chassis can be evaluated under real operating conditions.
