The 1972 Mercury Montego sat in the middle of Mercury’s early-1970s lineup, bridging family-car comfort, personal-luxury styling, and muscle-era carryover in GT and big-engine forms. That variety matters at tire time, because the 1972 Mercury Montego does not rely on one universal fitment across every configuration. Its primary tire sizes range from E78-14 through H78-14, with H70-14 also used on certain 429-equipped versions, all in bias-ply construction on 14-inch rims. Available choices include traditional whitewall treatments, blackwall truck-style options in some sizes, and modern radial equivalents for several primary sizes. The right selection starts with the exact sub-model, then balances appearance, wheel compatibility, and intended road use.
Which Tire Size Is Right for The 1972 Mercury Montego
The 1972 Mercury Montego uses five primary tire sizes, and the correct one depends on the exact sub-model and engine combination. All of these fitments are bias-ply sizes built for 14-inch rims, so the first step is confirming the specific Montego configuration rather than assuming every hardtop, GT, MX, Brougham, or wagon used the same tire. Once the right size is identified, the decision shifts to sidewall style, tire series, and whether a radial equivalent is worth considering.
H70-14 is a vintage alphanumeric bias-ply size, but the 70-series designation distinguishes it from the 78-series Montego fitments by placing it in a different profile family. On the 1972 Mercury Montego, it is used specifically on certain 429-equipped versions, making it a fitment that depends heavily on the exact sub-model. Product choices are not shown here, so the key value of this size is fitment accuracy rather than broad comparison among sidewall treatments or series. It should be evaluated as a distinct primary size, not grouped casually with H78-14 simply because both mount on 14-inch wheels.
Sub-model fitment varies throughout the 1972 Mercury Montego range, so tire selection starts with the exact body and engine combination. Several versions share overlapping size ranges, but others move into larger bias-ply fitments or a distinct H70-14 application, making sub-model confirmation essential before comparing products or radial equivalents.

1972 Mercury Montego 2 Dr. Hardtop w/250 Eng.
The 1972 Mercury Montego 2 Dr. Hardtop w/250 Eng. uses the smaller end of the Montego tire range, with E78-14 and F78-14 bias-ply fitments. That makes this sub-model a good example of why exact configuration matters before choosing between a traditional whitewall presentation, a blackwall alternative, or a radial-equivalent path.
The 1972 Mercury Montego GT w/250 & 302 Eng. moves into F78-14 and G78-14 bias-ply sizing on 14-inch rims. Tire selection here comes down to confirming which of those two primary sizes belongs on the car, then deciding how much emphasis to place on sidewall appearance and restoration-oriented style.
The 1972 Mercury Montego GT w/351 & 400 Eng. uses G78-14 and H78-14 bias-ply fitments, placing it in the larger part of the Montego size range. That opens the door to wider-looking traditional whitewall choices while making exact size verification important before considering any radial equivalent.
The 1972 Mercury Montego GT w/429 Eng. stands apart with a single H70-14 bias-ply fitment rather than the more common 78-series sizes. This makes size accuracy especially important, since the tire choice should reflect that distinct profile family before any construction change or appearance decision is made.
The 1972 Mercury Montego MX Brougham w/250 & 302 Eng. uses F78-14 and G78-14 bias-ply tires. Buyers looking at this sub-model should first narrow the car to the correct primary size, then compare sidewall treatment and overall presentation to suit a more formal Montego appearance.
The 1972 Mercury Montego MX Brougham w/351 & 400 Eng. uses G78-14 and H78-14 bias-ply tires on 14-inch wheels. Choosing between available tires here is less about rim diameter and more about confirming the exact size, then selecting a sidewall style that fits the car’s intended look and use.
The 1972 Mercury Montego MX Brougham w/429 Eng. uses H70-14 as its primary bias-ply size. Since this fitment differs from the H78-14 used elsewhere in the Montego family, owners should verify the wheel and vehicle setup carefully before treating the larger Montego sizes as interchangeable.
The 1972 Mercury Montego MX Hardtop w/429 Eng. uses H78-14 bias-ply tires. That keeps tire selection straightforward once the sub-model is confirmed, with the main decision shifting toward a traditional wide whitewall look or a radial-equivalent route checked against the existing wheel package.
The 1972 Mercury Montego MX w/250 & 302 Eng. uses F78-14 and G78-14 bias-ply sizes. Because both sizes appear within this sub-model grouping, the buyer should confirm the exact application first and only then compare available sidewall and series differences.
The 1972 Mercury Montego MX w/351/400/429 Eng. uses G78-14 and H78-14 bias-ply tires. That makes this sub-model more about sorting out the correct primary size than choosing construction, since all original-type fitments remain 14-inch bias-ply applications.
The 1972 Mercury Montego Wagon uses H78-14 bias-ply tires. With one primary size in play, the focus turns to keeping the correct 14-inch fitment, comparing the available traditional sidewall presentation, and checking wheel condition before putting a collector-era wagon back on the road.
The 1972 Mercury Montego w/250 & 302 Eng. uses F78-14 and G78-14 bias-ply sizes. Tire selection starts with confirming which of those two sizes belongs on the car, then choosing the look and product style that best matches the intended restoration or driving use.
The 1972 Mercury Montego w/351/400/429 Eng. uses G78-14 and H78-14 bias-ply sizes. The practical takeaway is to verify the exact fitment first, since both sizes share the same 14-inch rim diameter but represent different primary applications within the Montego range.
Bias-Ply to Radial Tire Conversion for the 1972 Mercury Montego
Radial equivalents are available for four of the primary 1972 Mercury Montego tire sizes. E78-14 can be compared with 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, with a 4-6 inch recommended rim-width range. F78-14 adds 750R14 as a bias-look radial alongside 195R14, P205/75R14, and P215/70R14, also on a 4-6 inch rim-width range. G78-14 and H78-14 follow the same pattern with 205R14, P215/75R14, P225/70R14, and 800R14 for G78-14, plus 215R14, P225/75R14, and P235/70R14 for H78-14, each requiring wheel and clearance checks before conversion.

Owners researching 1972 Mercury Montego tires usually need to sort out sub-model size differences first, then compare bias-ply fitment, radial equivalents, sidewall styles, and practical road-use checks. These FAQs focus on the exact size, wheel, and construction questions that matter most.
Tire Size & Fitment
What tire size fits a 1972 Mercury Montego?
The 1972 Mercury Montego uses five primary bias-ply tire sizes: E78-14, F78-14, G78-14, H78-14, and H70-14. The correct size depends on the exact Montego sub-model and engine combination, so there is not one universal tire size for every 1972 Montego.
The practical step is to identify the exact version of the car before comparing tires. Several Montego models share overlapping size ranges, while certain 429-equipped versions use H70-14 instead of the more common 78-series sizes, so matching the tire to the correct configuration matters before choosing sidewall style or considering a radial alternative.
What size rim does a 1972 Mercury Montego use?
The primary Montego tire sizes for 1972 all mount on 14-inch rims. That includes E78-14, F78-14, G78-14, H78-14, and H70-14, so wheel diameter stays consistent across the range even though the tire sizes themselves vary by sub-model.
That shared 14-inch diameter makes wheel confirmation simpler, but it does not mean every 14-inch Montego tire is interchangeable. Width class and profile still differ from one size to another, so the next step is checking the exact tire size called for by the car and confirming the actual wheel setup if aftermarket rims have been added.
Why does the 1972 Mercury Montego have more than one tire size?
The 1972 Mercury Montego was offered in several sub-model and engine combinations, and those combinations used different primary bias-ply tire sizes. Smaller-displacement versions could use E78-14 or F78-14, while larger-engine, GT, MX, Brougham, wagon, and 429-equipped variants moved into G78-14, H78-14, or H70-14 fitments.
That range means tire choice starts with vehicle identity, not just year and model name. A Montego owner should confirm the exact sub-model and current wheel setup before selecting a tire, especially since H70-14 and H78-14 may look related at a glance but represent different primary fitment paths.
Bias-Ply & Radial Options
Is E78-14, F78-14, G78-14, H78-14, or H70-14 a bias-ply or radial tire for the 1972 Mercury Montego?
All five primary 1972 Mercury Montego tire sizes are bias-ply fitments. E78-14, F78-14, G78-14, H78-14, and H70-14 all belong to vintage alphanumeric bias-ply sizing rather than modern radial sizing, even though radial equivalents are available for several of the 78-series applications.
Keeping the Montego on bias-ply tires preserves the original-style construction and appearance of the period sizing system. Anyone considering a radial alternative should treat that as a separate fitment decision, since wheel width, overall dimensions, and vehicle clearance still need to be checked rather than assumed from the matching 14-inch rim diameter.
What radial tire sizes are equivalent to Montego bias-ply sizes like E78-14, F78-14, G78-14, and H78-14?
E78-14 corresponds to 185R14, P195/75R14, and P205/70R14. F78-14 corresponds to 195R14, P205/75R14, P215/70R14, and 750R14 as a bias-look radial. G78-14 corresponds to 205R14, P215/75R14, P225/70R14, and 800R14 as a bias-look radial, while H78-14 corresponds to 215R14, P225/75R14, and P235/70R14.
Those equivalents give Montego owners several radial sizing formats to compare, from Euro-metric 80-series styles to P-metric 75- and 70-series alternatives, plus bias-look radial options where offered. The next step is checking the vehicle’s wheel width, overall tire dimensions, and body or steering clearance before choosing one as an alternative to the primary bias-ply size.
What should I check before converting my 1972 Mercury Montego from bias-ply to radial tires?
Start by confirming the Montego’s exact primary tire size, then compare only the radial equivalent sizes associated with that fitment. Wheel diameter must remain correct at 14 inches, and wheel width should be checked against the recommended radial-equivalent rim-width range for the size being considered.
Construction changes can affect how the tire sits on the wheel and how much space it uses in the wheel opening, so the car should be checked for steering clearance, suspension clearance, and fender room. A Montego with replacement wheels, altered ride height, or other chassis changes deserves extra attention before moving away from the original bias-ply fitment.
Choosing the Right Tire
What should I consider when choosing a Montego tire for a 1972 Mercury Montego?
The starting point is the exact primary size for the car, since the 1972 Mercury Montego used E78-14, F78-14, G78-14, H78-14, or H70-14 depending on sub-model and engine combination. After size is confirmed, the next considerations are construction, sidewall style, tire series, and whether a radial equivalent is being evaluated instead of a bias-ply tire.
Appearance and intended use matter a great deal on a Montego. A restoration-oriented car may lean toward a traditional whitewall bias-ply presentation, while a driver may focus more on equivalent radial options and wheel compatibility, so the best choice comes from matching the tire to both the exact fitment and the car’s planned role.
What sidewall styles are available for 1972 Mercury Montego tires?
Sidewall choices for 1972 Mercury Montego tires include wide whitewall, narrow whitewall, dual white stripe, and blackwall, depending on the size. G78-14 shows the broadest appearance range, while some other Montego sizes are more limited and may center on a single wide whitewall offering or, in E78-14, selected blackwall options.
That variety makes sidewall style one of the biggest visual decisions once the correct size is established. A wide whitewall creates a more formal early-1970s presentation, dual white stripe and narrow whitewall can change the car’s visual balance, and blackwall choices can suit a more understated or utility-oriented look in sizes where they are available.
What brands offer tires for the 1972 Mercury Montego?
Available brands for 1972 Mercury Montego tire sizes include Coker Classic, BFGoodrich, and STA. The brand mix changes by size, with some fitments showing only one brand choice and others, especially G78-14 and E78-14, offering broader comparison across different tire series and sidewall treatments.
Brand selection should be treated as one part of the decision rather than the whole decision. The buyer still needs to compare the exact size, construction, sidewall presentation, rim-width suitability, and overall vehicle goals, since a Montego being restored for period style may call for a different visual approach than one being prepared for regular road use.
Restoration & Appearance
Which tire should I choose for a period-style 1972 Mercury Montego?
A period-style 1972 Mercury Montego starts with the correct primary bias-ply size for the exact sub-model, then narrows the choice by sidewall treatment and tire series. Wide whitewall options appear across several Montego sizes, while G78-14 also opens the door to narrow whitewall and dual white stripe choices for a different early-1970s presentation.
The right look depends on how the car is being finished rather than on one universal answer for every Montego. Owners aiming for a highly exact restoration should compare the tire choice against marque references, photos, and vehicle-specific historical material, while buyers pursuing a strong period feel can use the proper size and a traditional bias-ply sidewall as the foundation.
How does tire construction affect the appearance of a restored 1972 Mercury Montego?
Construction has a visible effect on a restored 1972 Mercury Montego because the original primary fitments are bias-ply sizes with vintage alphanumeric sizing. Staying with bias-ply maintains the classic sidewall and overall visual character associated with the Montego’s era, while radial alternatives can change that presentation even when they serve as size equivalents.
That difference matters most on a car where stance and period impression are part of the build goal. A bias-look radial can help narrow the visual gap where one is offered, but it should still be treated as an alternative construction choice and checked carefully against the wheel, size, and clearance requirements of the specific Montego.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1972 Mercury Montego?
Yes, modifications can affect tire fitment on a 1972 Mercury Montego even when the tire size itself is correct for the original application. Aftermarket wheels, changes in wheel width, altered offset, suspension work, ride-height changes, or body modifications can all influence how much room the tire has at the fender and steering components.
That is especially important when the car is being moved from bias-ply tires to a radial equivalent. A Montego with non-stock wheels or chassis changes should have its wheel dimensions and clearances checked directly on the car, since the original fitment chart only establishes the primary tire size, not the suitability of every modified setup.
What should I inspect before driving a 1972 Mercury Montego on new tires?
Before driving a 1972 Mercury Montego on new tires, inspect the wheels for damage or excessive rust, confirm the tires match the correct size for the car, and make sure they are mounted and inflated properly. It is also wise to check lug hardware, valve stems, and visible clearance at the suspension, steering, and fender edges.
A collector-era car benefits from a broader once-over before regular road use. Brake condition, alignment, wheel-bearing health, and suspension wear can all affect how a Montego behaves on fresh tires, so a careful inspection helps the new set perform as intended and reduces the chance of discovering unrelated chassis problems on the first drive.
How should 1972 Mercury Montego tires be maintained on a collector car?
Tires on a collector 1972 Mercury Montego should be checked regularly for air loss, uneven wear, sidewall cracking, cuts, bulges, and signs of age-related hardening. Cars that spend long periods parked deserve extra attention because low annual mileage can hide deterioration that is easy to miss during casual visual checks.
Storage conditions matter as much as mileage on an older Montego. Keeping the car away from prolonged sunlight, moisture, and ozone sources helps preserve the tires, while periodic pressure checks and occasional movement can reduce flat-spotting and help reveal developing issues before a longer drive or show-season return to the road.
