1968 Mercury Montego Tires

A 1968 Mercury Montego can use 735-14, 775-14, or F70-14 depending on the specific sub-model. All three are 14-inch bias-ply fitments, but they are not used across the lineup in the same way. The 6 Cyl. Hardtop uses 735-14 or 775-14, the Wagon uses 775-14, the GT & 427 V8 Eng. uses F70-14, and All Other Models use 775-14 or F70-14.

The practical first step is identifying the exact Montego configuration and then confirming the wheels actually on the car today. Many surviving cars have had wheels, suspension parts, or even complete driveline packages changed over the years, so the safest buying approach is to match the tire size to the sub-model and then verify wheel width and clearance before making a final selection.

The covered tire fitments for the 1968 Mercury Montego all use a 14-inch rim diameter. That applies to 735-14, 775-14, and F70-14, so the rim diameter stays consistent even though the tire size itself changes between sub-models. The main difference is not wheel diameter, but the tire’s width class and the rim-width range associated with the specific tire being considered.

Rim diameter is only one part of proper fitment, especially on a vintage intermediate car with several original size paths. A 14-inch wheel still needs the right width for the selected tire, and that matters more once moving from 735-14 to 775-14 or F70-14. Checking the stamped wheel size or measuring the wheel before purchase helps avoid mismatching the tire to the rim.

The 1968 Mercury Montego uses more than one tire size because fitment changes across sub-models and configurations. A six-cylinder hardtop, a wagon, and a GT or 427 V8 car were not all set up the same way, so Mercury’s tire sizing ranged from numeric bias-ply sizes like 735-14 and 775-14 to the alphanumeric F70-14. Even within some sub-model groupings, more than one accepted size appears.

That means the tire decision starts with the exact version of the car rather than the Montego name alone. It also helps to confirm whether the car still carries its original wheel type or has been changed at some point in its life. Once the correct size family is established, the remaining choices become sidewall style, brand, series, and whether to stay with bias-ply construction or consider a radial equivalent.

F70-14 is a bias-ply tire size on the 1968 Mercury Montego. It is a vintage alphanumeric bias-ply designation used on 14-inch rims, and it appears on the GT & 427 V8 Eng. sub-model as well as some All Other Models fitments. In the available tire choices for this Montego, F70-14 remains rooted in period-style bias-ply construction rather than as a primary radial fitment.

That matters because an owner choosing F70-14 is often deciding between maintaining a muscle-era tire look or evaluating a radial alternative separately. The wheel width associated with available F70-14 products is broader than the narrower numeric sizes, so the wheel itself should be confirmed before purchase. Sidewall style also plays a major role here, since redline, pin-white-stripe, and raised white letter versions are all available.

Radial equivalents for 775-14 on a 1968 Mercury Montego include 195R14 as an 80-series metric radial, P205/75R14 as a 75-series P-metric radial, P215/70R14 as a 70-series P-metric radial, and 750R14 as a bias-look radial. These are alternative sizing paths built around the original 775-14 fitment rather than additional primary factory-style Montego tire sizes.

The difference between those options is mainly the sizing convention and visual character, especially with 750R14 carrying a more traditional bias-look appearance. A recommended rim-width range of 4-6 inches is associated with these equivalents, but that should still be checked against the actual wheel on the car. Clearance at the fender and suspension should also be reviewed before changing construction or profile family.

That choice depends on what matters most for the car’s intended use and presentation. The 1968 Mercury Montego’s primary fitments are bias-ply in 735-14, 775-14, and F70-14, so staying with bias-ply preserves the original sizing language and period-style appearance. Radial equivalents are available for each primary size, giving owners another path without changing the Montego to a different rim diameter.

A restoration-focused car often stays with bias-ply because sidewall shape, tread style, and available stripe treatments all support a late-1960s look. A road-driven car may lead an owner to evaluate radial equivalents, but the decision should include wheel width, physical clearance, and the vehicle’s present setup rather than tire size alone. Matching all four tires and keeping construction consistent side to side is also important.

Start by confirming that 775-14 is the correct primary size for the specific 1968 Mercury Montego sub-model, since this car also uses 735-14 and F70-14 in other configurations. Once the size is confirmed, the main choices in 775-14 involve brand, sidewall appearance, and rim-width compatibility. Available options include BFGoodrich, Firestone, and US Royal, with blackwall, narrow whitewall, redline, goldline, and blueline treatments.

The right pick depends on whether the Montego is being restored with a subtle stock-style look or a more distinctive period visual treatment. Product details such as rim-width range and max load capacity at the stated pressure also become more useful at this stage, especially if the car sees regular road use. Comparing those details within the same size is more productive than jumping between sizes that belong to different sub-models.

Sidewall choices for 1968 Mercury Montego tires vary by size, but the range is broad. Depending on whether the car uses 735-14, 775-14, or F70-14, available styles include blackwall, narrow whitewall, redline, goldline, blueline, pin-white-stripe, and RWL, which is the traditional raised white letter look. Those choices give the Montego owner room to move from understated touring presentation to more aggressive late-1960s muscle styling.

The most appropriate style usually depends on the sub-model and the overall look of the car rather than on fitment alone. A wagon or six-cylinder hardtop may suit a different visual treatment than a GT & 427 V8 Eng. car, even when both remain within proper period-style sizing. Sidewall style should be chosen after the correct tire size is established, not as a substitute for confirming fitment.

Tires for the 1968 Mercury Montego are available from BFGoodrich, Firestone, Goodyear, and US Royal, depending on the size. BFGoodrich appears in 735-14 and 775-14, Firestone and US Royal both appear in 775-14, and Firestone plus Goodyear are available in F70-14. The mix changes with the fitment, so brand choice is tied directly to the specific tire size the Montego uses.

That means the first filter should always be size, followed by construction and wheel compatibility, and only then brand or styling preference. Once the right size is pinned down, brand choice becomes a way to compare tire series and sidewall treatments rather than a separate fitment decision. For many Montego owners, the final brand choice is as much about visual character as about matching the correct size family.

A period-style 1968 Mercury Montego should begin with the correct primary size for the exact sub-model: 735-14, 775-14, or F70-14, all in bias-ply construction. That keeps the car within the size families associated with its covered late-1960s fitments. From there, the choice becomes more visual, with some sizes emphasizing understated classic sedan or wagon presentation and others offering a stronger muscle-era look.

For a restoration-oriented car, the tire should support the vehicle’s overall personality without forcing a style from a different configuration. Sidewall treatments such as narrow whitewall, redline, goldline, pin-white-stripe, or raised white letter can all shift the car’s appearance significantly. When exact originality matters beyond period style, marque-specific research and historical references should guide the final finishing details.

Tire construction has a visible effect on a restored 1968 Mercury Montego because the car’s primary fitments are all bias-ply sizes. A bias-ply tire preserves the vintage sizing language and generally keeps the car within the look expected of a late-1960s Montego. Radial equivalents remain available, but they present the car through modern metric or P-metric sizing conventions unless a bias-look radial is chosen where one exists.

That appearance difference matters most on cars where stance, wheel opening fill, and sidewall detailing are central to the finished restoration. F70-14, for example, also opens the door to highly era-specific stripe and letter treatments that shape the Montego’s visual tone. Owners chasing a road-friendly alternative can still consider radial equivalents, but should compare the tire’s look as carefully as its fitment.

Yes, modifications can affect tire fitment on a 1968 Mercury Montego even when the tire size itself is correct for the sub-model. Aftermarket wheels, wheel-width changes, altered ride height, suspension work, or brake conversions can all change how a 735-14, 775-14, or F70-14 tire sits in the car. That matters even more when a radial equivalent is being considered instead of the original bias-ply construction.

The practical check is to measure the wheels actually on the car and inspect clearance at the fenders, steering components, and suspension before ordering. A Montego that has been lowered or fitted with non-original wheels may need closer review than a stock car. Size alone does not account for every variable, so the current physical setup should always guide the final fitment decision.

Before driving a 1968 Mercury Montego on new tires, inspect the wheels for correct diameter and condition, confirm the lug hardware seats properly, and make sure the tires are inflated appropriately for the chosen product. It is also wise to check for rubbing at full steering lock and during suspension movement, especially if the car uses F70-14 or has had wheel or suspension changes over time.

A collector car that has spent long periods parked also deserves a broader look before road use. Brake condition, wheel bearings, alignment, and suspension wear can all affect how a fresh set of tires behaves on the road. After the first few drives, recheck air pressure and look for any signs of uneven contact, sidewall scuffing, or interference that would suggest the setup needs adjustment.

Collector-car tires on a 1968 Mercury Montego should be checked regularly for air loss, tread wear, cracking, bulges, cuts, and any sign that the car has been sitting too long in one position. That advice applies whether the Montego is running a bias-ply primary fitment or a radial equivalent. Low annual mileage does not stop tires from aging, and a car that looks road-ready can still be riding on compromised rubber.

Storage conditions matter almost as much as mileage on a vintage Montego. Keeping the car away from prolonged heat, direct sunlight, moisture, and ozone sources helps preserve the tires’ condition over time. It also helps to move the car periodically or store it in a way that reduces flat-spotting pressure. A close inspection before each driving season is a sensible routine for any low-use collector vehicle.
