1968 Ford Mustang Tires

A 1968 Ford Mustang can use 695-14, 735-14, E70-14, FR70-14, or F70-14, depending on the exact sub-model. The 6 Cyl. & 302 V8 uses 695-14 or 735-14, the 390 V8 uses 735-14 or E70-14, the 427 V8 uses FR70-14, and the GT uses F70-14.

That means tire selection starts with identifying the exact version of the car, not simply the model year. All of these fitments use a 14-inch rim, but the size code and construction can still differ significantly. Checking the current wheel setup and the size already on the car helps narrow the right replacement path before comparing brands or sidewall styles.

The tire fitments used across this 1968 Ford Mustang range are built around a 14-inch rim diameter. That applies to the numeric bias-ply sizes, the alphanumeric bias-ply sizes, and the FR70-14 radial application tied to the covered sub-models.

Rim diameter is only part of the fitment picture, because wheel width still varies by tire size and product. A 695-14 tire does not call for the same wheel-width range as an E70-14 or F70-14 tire, even though all of them fit a 14-inch wheel. Verifying both wheel diameter and wheel width is a smart step before changing size, construction, or sidewall style.

The 1968 Ford Mustang has more than one tire size because tire fitment changes across the covered sub-models. Six-cylinder and 302 V8 cars use different sizes than the GT, the 390 V8 has its own bias-ply choices, and the 427 V8 uses the FR70-14 radial format.

That variation reflects how the Mustang range could be configured differently even within one model year. A buyer should confirm the exact sub-model first, then compare the wheel setup already on the car. Restored cars, long-ago wheel changes, and older replacement tires can all blur what belongs there, so the current setup deserves a close look before ordering.

F70-14 is a bias-ply tire size for the 1968 Ford Mustang GT. It is part of the vintage alphanumeric bias-ply sizing system and appears in period-style series such as Firestone Wide Oval and Goodyear Custom Wide Tread or Speedway Wide Tread.

That matters because F70-14 is the primary fitment, while any radial alternative should be treated as an equivalent rather than the same tire. If the goal is to preserve a traditional late-1960s look, staying with F70-14 bias-ply keeps the original sizing convention and available sidewall treatments. Wheel width and overall vehicle setup still need to be checked before trying a radial alternative.

Radial equivalents for F70-14 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 equivalent. These alternatives keep the same 14-inch rim diameter while using different radial sizing conventions.

Each option gives the buyer a slightly different path, whether the goal is a more traditional radial format or a bias-look presentation. The recommended rim-width range is 4-6 inches, which makes wheel measurement important before changing from the original bias-ply size. Clearance, suspension condition, and the car's existing wheel setup should all be reviewed before making the switch.

Start by confirming the Mustang's actual original tire size, wheel diameter, and wheel width, then compare those against the radial equivalent being considered. On a 1968 Ford Mustang, the relevant radial equivalents vary by primary size, so the conversion path for a 695-14 car is different from an F70-14 or E70-14 car.

A careful conversion also means checking steering clearance, fender clearance, suspension condition, and the car's current ride height. Radial equivalents share the same basic fitment intent but are not automatic replacements. If the Mustang has aftermarket wheels or past suspension changes, those details become just as important as the tire size itself before moving away from bias-ply construction.

Start with the exact sub-model and tire size, because a 1968 Ford Mustang does not use one universal fitment. The covered applications span 695-14, 735-14, E70-14, FR70-14, and F70-14, with both bias-ply and radial construction represented in the range.

Once the correct size is confirmed, compare wheel-width compatibility, sidewall style, tire series, and the visual character you want from the car. A narrow whitewall 695-14 creates a very different look than an F70-14 raised white letter tire. Buyers also benefit from checking load figures and intended road use so the selected tire matches both the vehicle setup and the finished appearance.

1968 Ford Mustang tire choices include blackwall, narrow whitewall, redline, pin-white-stripe, raised white letter, dual redline, and a raised-white-letter Blue Streak style depending on the tire size. Sidewall selection varies by fitment, so the available look for 695-14 is not the same as the options offered in E70-14 or F70-14.

That makes appearance an important secondary decision after the correct size is established. A small-block car on narrow whitewalls presents very differently from a GT on redlines or raised white letters. The best approach is to match sidewall treatment to the car's actual size, wheel setup, and restoration direction rather than choosing only by style preference.

Tires for the 1968 Ford Mustang are available from BFGoodrich, Firestone, Goodyear, and US Royal across the covered fitments. Brand availability depends on size, with some sizes leaning toward traditional passenger-car styling and others offering more muscle-era series such as Wide Oval, Blue Streak, or Custom Wide Tread.

Choosing among brands works best after narrowing the exact tire size and the appearance the car needs. A buyer may be comparing whitewall versus blackwall in 695-14, or redline versus raised white letter in E70-14 or F70-14. Tire series, sidewall treatment, and wheel-width compatibility usually shape the decision more than the brand name by itself.

A period-style 1968 Ford Mustang tire starts with the size used by the car's exact sub-model, then moves to the construction and sidewall treatment that best suit the finished look. Bias-ply sizes such as 695-14, 735-14, E70-14, and F70-14 all support a traditional presentation, while FR70-14 serves the radial application within this range.

After the correct size is established, the visual direction becomes clearer. Narrow whitewalls tend to suit a more restrained street presentation, while redlines, pin-white-stripes, and raised white letters lean toward a stronger late-1960s performance look. When exact originality matters, vehicle-specific restoration references and marque expertise are worth consulting before choosing a sidewall style.

Tire construction changes the visual character of a restored 1968 Ford Mustang as much as the size code does. A bias-ply tire usually supports the earlier period-style shape and stance many restorers want, while the FR70-14 radial application and radial equivalents can shift the car toward a more modern-looking presentation.

That difference becomes even more noticeable once sidewall treatment enters the picture. A redline or raised white letter bias-ply tire gives a very different impression than a blackwall or narrow whitewall passenger-style tire in a smaller numeric size. Matching construction to the car's intended era, trim theme, and wheel setup usually leads to a more coherent finished appearance.

Yes, modifications can affect tire fitment on a 1968 Ford Mustang even when the tire size matches a correct year-specific application. Aftermarket wheels, different wheel widths, suspension changes, altered ride height, or brake upgrades can all change the space available around a 14-inch tire.

That is especially important on a Mustang with multiple possible sizes across the model range. A car that originally used 695-14 or 735-14 may have been changed over the years, and a GT or big-block car may no longer wear its original wheel setup. Measuring the current wheel and checking clearance at full steering lock helps avoid surprises before installation.

Before driving a 1968 Ford Mustang on new tires, inspect the wheels for correct diameter and width, confirm that the tire beads seat properly, and check inflation pressure carefully. It is also wise to look over steering and suspension components, especially on a collector car that may have sat for long periods.

A road-ready inspection should include tread and sidewall condition on any other tires still in service, plus a look for rubbing marks, bulges, cuts, and signs of air loss. On an older Mustang, dried bushings, weak springs, or prior bodywork can influence clearance more than expected. A short, cautious initial drive is a sensible way to confirm everything behaves normally.

Collector-car tires on a 1968 Ford Mustang should be checked regularly for pressure, cracking, flat spotting, tread wear, and any sign of sidewall damage, even if the car is driven sparingly. Low annual mileage does not prevent aging, and older bias-ply or radial tires can deteriorate long before the tread looks used up.

Storage conditions matter just as much as road use. Keeping the car away from prolonged sunlight, moisture, and ozone sources helps preserve the tires, and moving the vehicle occasionally can reduce long-term flat spotting. Before any longer drive, give the tires and wheels a fresh inspection so the Mustang is not relying on age-hidden problems.
