1972 Mercury Tire Fitment Guide

1972 Mercury vehicles use 13 different sizes across seven model lines. The Capri uses 165R13 and 185/70R13 on 13-inch rims. The Comet uses D70-14, 6.45-14, and B78-14 on 14-inch rims. The Cougar uses E78-14 and F70-14, while the Montego uses E78-14, F78-14, G78-14, H78-14, and H70-14, all on 14-inch rims. The Marquis, Monterey, and Wagons move to 15-inch sizes, with H78-15 shared by Marquis, Monterey, and Wagons, and G78-15 specific to Monterey.

The practical takeaway is that a 1972 Mercury owner needs to identify the model before choosing a tire, because the rim diameter changes across the range and several sizes are model-specific. Rim width guidance also varies by size where product coverage exists, from 4.50-6.00 inches for 165R13, 5.00-6.50 inches for 185/70R13, 4.50-7.00 inches for E78-14, 6.00-7.00 inches for F70-14, 5.00-7.00 inches for F78-14 and G78-14, 5.50-8.00 inches for H78-14, 5.00-7.00 inches for G78-15, and 5.50-7.00 inches for H78-15.

On a 1972 Mercury Capri, 165R13 is a euro-metric radial size. The 165 is the section width in millimeters, the R identifies radial construction, and the 13 is the wheel diameter in inches. Because no aspect ratio is written into the size, this format is conventionally treated as an 80-series radial. For the Capri, that makes 165R13 a distinctly European-style fitment compared with the domestic alphanumeric bias-ply sizes used elsewhere in the Mercury lineup.

That coding matters because a 165R13 does not translate directly to the 14- and 15-inch domestic sizes used on other 1972 Mercury models. It stays within the Capri's 13-inch wheel family and gives you a narrower radial profile than 185/70R13. If you are trying to match an original imported-market look or preserve the car's early-1970s touring character, this is usually the size to investigate first before moving to the wider Capri alternative.

No. The 1972 Mercury range is split by both model and wheel diameter. Capri uses two radial 13-inch sizes, Comet uses three 14-inch bias-ply sizes, Cougar uses two 14-inch bias-ply sizes, Montego uses five 14-inch bias-ply sizes, Monterey uses two 15-inch bias-ply sizes, and Marquis and Wagons use H78-15. Even where a size is shared, it is only shared by part of the lineup, such as E78-14 between Cougar and Montego or H78-15 across Marquis, Monterey, and Wagons.

That means year and make alone are not enough to select a tire for a 1972 Mercury. A Capri owner is choosing between two radial metric sizes on 13-inch wheels, while a full-size Marquis owner is in a completely different 15-inch bias-ply category. If the car's current tires do not match the wheel or the model's expected family of sizes, verify the wheel diameter and compare against the actual sidewall markings before settling on a replacement.

For a 1972 Mercury Capri, both sizes are radial 13-inch fitments, but they create a different visual and dimensional result. 165R13 is the narrower euro-metric radial with an implied 80-series profile, while 185/70R13 is wider and has a clearly stated lower profile. The 165R13 choices center on blackwall touring-style radials from Michelin and Dunlop, while 185/70R13 opens the door to blackwall, redline, and wide whitewall versions from BFGoodrich, Avon, and Dunlop.

Choose 165R13 if your priority is preserving the Capri's slimmer, more original-feeling European tire appearance. Choose 185/70R13 if you want a broader footprint, a lower-profile stance, or sidewall styling such as redline or whitewall. Both fit the Capri's 13-inch wheel family, but their approved rim-width ranges are not identical across all products, so it is worth checking the actual wheel width before deciding between the two.

1972 Mercury tire choices cover a wide range of sidewall styles depending on model and size. Capri radial sizes include blackwall on 165R13 and blackwall, redline, and wide whitewall on 185/70R13. Comet and Cougar sizes add muscle-era looks such as RWL, redline, and pin white stripe on D70-14 and F70-14. Montego, Monterey, Marquis, and Wagon fitments lean more heavily into whitewall and blackwall options, with G78-14 also available in dual white stripe and narrow whitewall.

The right sidewall is often as much about the car's character as the size itself. Sportier models such as Capri, Comet, and Cougar can look at home with blackwall, redline, or raised-white-letter presentations, while luxury-oriented Marquis, Monterey, and many Montego restorations often call for whitewall treatments. If the car is being restored for judged events, sidewall style can matter almost as much as size and construction, so compare your choice to period photos and marque-club guidance.

1972 Mercury tires are available from Michelin, Dunlop, BFGoodrich, Avon, Firestone, Goodyear, Coker Classic, and STA, depending on size. Capri radial sizes are covered by Michelin and Dunlop in 165R13, and by BFGoodrich, Avon, and Dunlop in 185/70R13. Comet and Cougar performance-flavored bias-ply sizes draw from Firestone and Goodyear, while many Montego, Marquis, Monterey, and Wagon sizes use Coker Classic, BFGoodrich, and STA.

Brand choice on a 1972 Mercury usually comes down to the look and character you want within the correct size. Some brands focus on blackwall or European-style radial presentation, while others offer period domestic sidewall treatments such as redlines, raised white letters, pin white stripes, or wider whitewalls. Once the model and size are nailed down, comparing brands is most useful as a way to narrow the right appearance and construction rather than to reinvent the fitment itself.

Rim width varies by size across the 1972 Mercury range. 165R13 fits 4.50-6.00-inch rims, and 185/70R13 fits 4.5-6.0 or 5.00-6.50-inch rims depending on the product. Among the 14-inch sizes with coverage, D70-14 uses a 6-inch rim, E78-14 spans 4.50-7.00 inches or 5.0-6.0 inches, F70-14 uses 6.00-7.00 inches, F78-14 and G78-14 use 5.00-7.00 inches, and H78-14 uses 5.50-8.00 inches. On 15-inch full-size fitments, G78-15 uses 5.00-7.00 inches and H78-15 uses 5.50-7.00 inches.

Those ranges show why matching a 1972 Mercury tire to the wheel is about more than rim diameter alone. Two tires may both fit a 14-inch wheel but still expect different rim widths for proper profile and footprint. If the car has aftermarket wheels or if the original wheels have been swapped between models, measure the wheel before choosing a tire, especially on Montego applications where several 14-inch sizes exist within one model family.

Tube requirements are not the same across every 1972 Mercury size. The 165R13 Capri radial offerings are tubeless in Michelin form, while tube status varies by product overall in that size because not every version is marked the same way. E78-14 includes an STA tubeless product, and most of the other covered sizes are not uniformly identified here as tube-type or tubeless. That makes it important to treat tube use as a product-by-product and wheel-by-wheel decision rather than a blanket rule for the whole model year.

The real-world check is the wheel as much as the tire. Even when a tire is tubeless-capable, an older wheel condition, riveted construction, or restoration goal may still influence whether a tube is appropriate. Before mounting tires on a 1972 Mercury, inspect the wheel's condition, verify whether the specific tire carries a tubeless marking, and make sure the valve stem and wheel surface are suited to the setup you plan to run.

Original 1972 Mercury wheels can only be shared among tire sizes that use the same rim diameter, and even then rim width still matters. Capri sizes stay within a 13-inch wheel family, most Comet, Cougar, and Montego sizes are 14-inch, and Marquis, Monterey, and Wagons use 15-inch sizes. A 14-inch Comet or Montego wheel cannot take a Capri 13-inch tire, and a 15-inch Marquis or Monterey wheel cannot take the 14-inch intermediate sizes.

Within the same diameter, there can be overlap, but it is not automatic. For example, several 14-inch Mercury sizes have different approved rim-width ranges, so a wheel that works for one may not be ideal for another. If your 1972 Mercury has changed hands over the years or wears mixed components, confirm both the wheel diameter and width before assuming the original wheels are suitable for every size associated with that model line.

A 1972 Mercury should be stored in a cool, dry, dark space with the tires protected from sunlight, ozone sources such as electric motors and battery chargers, and standing moisture. Keep the tires properly inflated, roll the car periodically if possible, and avoid letting one contact patch carry the same load for months at a time. Bias-ply tires, which make up most of the 1972 Mercury range, are more prone to temporary flat-spotting during long static storage than the Capri's radial sizes.

Collectors who store a 1972 Mercury for winter or between shows often use tire cradles or stands to reduce long-term stress, especially on heavier full-size cars such as Marquis, Monterey, and Wagons. Clean tires with mild soap and water rather than petroleum-based dressings, and keep the car away from welding equipment or furnaces that can accelerate rubber aging. Good storage habits preserve both appearance and drivability when the car comes back out.

For a 1972 Mercury, age is usually a more important guide than mileage. Collector vehicles often wear tires that look barely used but are many years old, and rubber compounds harden over time even when tread depth remains strong. A sensible practice is to begin evaluating tires closely at around five to seven years of age and to give serious replacement consideration by about ten years, using the DOT date code and the tire's overall condition as your reference points.

That rule applies whether your 1972 Mercury runs Capri radials or the bias-ply sizes used on the rest of the lineup. A low-mileage garage-kept car can still age out its tires, and a heavily accessorized show car may hide sidewall deterioration behind its visual presentation. If the tires are older, ride quality changes, cracking, or unexplained air loss are all signs to inspect more closely rather than relying on tread appearance alone.

Tires on a 1972 Mercury should be checked before every drive and inspected more thoroughly before any longer outing. Look for sidewall cracking, tread separation, bulges, punctures, irregular wear, and pressure loss. On any setup that uses or may use tubes, the condition of the valve stems and any sign of slow leakage deserve extra attention. Full-size models that carry more weight can also reveal aging through stance changes or shoulder wear before a failure becomes obvious.

A short pre-drive walkaround can prevent a ruined trip and, more importantly, catch trouble before it becomes unsafe. Collector cars often sit for long intervals, so inspection needs are tied to storage time as much as distance traveled. If your 1972 Mercury has been parked for weeks or months, check pressures cold, examine both sidewalls where visible, and inspect the spare as carefully as the four tires on the ground.

The 1972 Mercury Capri stands apart from the rest of the Mercury lineup because it uses radial metric sizing rather than the domestic bias-ply formats common on the other models. The Capri's sizes are 165R13 and 185/70R13, both on 13-inch wheels, which aligns with the Capri's European design roots and imported-market flavor. While bias-ply tires still dominated many American cars in 1972, the Capri belongs to the group of period vehicles where radial fitment is part of the original character rather than a later modernization.

For a restoration, the key is not just choosing a 13-inch tire but matching the Capri's correct radial type and visual stance. The narrower 165R13 is often closer to an original touring presentation, while 185/70R13 creates a wider and lower-profile look. If your car is destined for marque judging, check market-specific factory literature or a Capri specialist, since wheel and tire details can vary by trim, market, and how the car was originally delivered.

Correct tire fitment matters on a 1972 Mercury because judges and knowledgeable enthusiasts notice the relationship between the car's era, model, construction type, size family, and sidewall treatment. A Capri wearing the wrong domestic-style bias-ply format would look out of place, just as a Marquis or Monterey on an incorrect lower-profile modern-looking radial could break the period presentation. Sidewall details such as wide whitewalls, narrow whitewalls, redlines, pin white stripes, and raised white letters can also shape how authentic the finished car appears.

What counts as correct depends on the model and the standard you are building toward. A local cruise-night car may simply need the right overall visual tone, while concours judging can scrutinize size, construction, and sidewall style much more closely. If your 1972 Mercury is being restored for serious competition, compare against period photos, factory literature, and the expectations of the specific club or event rather than relying only on what looks plausible at a glance.

For a 1972 Mercury Capri using 165R13, Michelin offers both the XAS and XAS-FF. Both are blackwall radial tires marked 165HR13 82H TL, both fit 13-inch rims, and both share the same 4.50-6.00-inch rim-width range. The key distinction in the available specifications is series identity and weight, with the XAS-FF shown at 20 pounds and the XAS shown at 9 pounds.

For a Capri owner, that means the decision is less about basic fitment and more about which Michelin series best suits the restoration or driving character you want. Because the sidewall style, size marking, speed rating, and rim-width range are the same, this comparison comes down to product family preference and how closely you want to mirror a particular period look. If authenticity is the goal, period photos and marque-specific guidance can help narrow the right series choice.

1972 Mercury tires can be suitable for highway driving when they are the correct size, in sound condition, and used within their construction and speed limits. The Capri's radial sizes include H-rated products with a 130 mph ceiling and a V-rated product with a 149 mph ceiling, while many of the bias-ply domestic sizes here do not carry modern speed letters in the same way. In normal collector-car use, the tire's condition and the car's overall mechanical health are usually more important than chasing the highest theoretical speed rating.

A 1972 Mercury should be approached as an older vehicle system, not just a set of tires. Brakes, steering play, alignment, suspension bushings, and wheel condition all affect highway confidence, especially on full-size cars or on bias-ply tires that follow road grooves differently than radials. If the tires are fresh and the car is mechanically sorted, occasional highway use is realistic, but sustained high-speed driving should respect both the tire's rating and the vehicle's era.

Inflation pressure for a 1972 Mercury should start with the factory recommendation for the specific model and then be checked against the reproduction tire's own maximum load-and-pressure marking. Several sizes here include load figures such as 1,135 pounds at 35 psi for some 185/70R13 products, 1,320 pounds at 32 psi for D70-14, 1,400 pounds at 32 psi for one E78-14 whitewall, 1,500 pounds at 32 psi for F70-14 and F78-14, 1,620 pounds at 32 psi for G78-14 and G78-15, and 1,770 pounds at 32 psi for H78-14 and some H78-15 products.

Those numbers are load-capacity references, not universal operating pressures for every 1972 Mercury. They should never be transferred from one size to another or from one model line to a different wheel and tire package. Use the owner's manual or factory placard to establish the car's intended cold pressure, then confirm that the chosen tire is being used within its rated limits. If your Mercury carries passengers or cargo more often than a typical collector car, pressure checks become even more important.

Before a longer drive in a 1972 Mercury, inspect all five tires if the car carries a spare. Check for cracking, cuts, bulges, punctures, uneven wear, and cold inflation pressure, and make sure the tread is free of objects that may have worked in during storage. On any setup that may use tubes, valve-stem condition and slow-leak behavior deserve special attention. Full-size cars should also be checked for visible overloading or sag that can put extra stress on older tires.

A tire check should be part of a broader pre-drive routine on a car of this age. Confirm wheel fastener security, steering feel, brake operation, fluid levels, lighting, and the condition of belts and hoses before committing to distance. If your 1972 Mercury has been stored for an extended period, start with a shorter shake-down drive near home before heading onto faster roads or carrying passengers for an all-day trip.
