1968 Plymouth Barracuda Tires

A 1968 Plymouth Barracuda can use 695-14, D70-14, or E70-14 depending on the exact sub-model and setup. Base and disc-brake cars use 695-14 or D70-14, while the Formula S uses E70-14. All three are bias-ply fitments built for 14-inch rims, so the right answer starts with identifying the specific Barracuda configuration rather than choosing by appearance alone.

Once the sub-model is confirmed, the next step is matching the tire to the wheel already on the car. A Barracuda that has been restored, modified, or converted to a different wheel package may no longer reflect its original-type setup, so checking the rim diameter and current size on the vehicle helps avoid ordering the wrong tire format.

The tire fitments used on the 1968 Plymouth Barracuda are all built around a 14-inch rim diameter. That applies to 695-14, D70-14, and E70-14, even though the tires use different vintage sizing systems. Rim width can still vary by tire size and product, so 14 inches is only the starting point when confirming wheel compatibility.

A 14-inch wheel does not automatically make every Barracuda tire size interchangeable. Width, profile family, and the actual wheel on the car still matter, especially if the car has aftermarket wheels or a different sub-model wheel package. Checking the stamped wheel size or measuring the wheel before ordering is a sensible step on any car with an uncertain history.

The 1968 Plymouth Barracuda has more than one tire size because fitment varies by sub-model and configuration. Base and disc-brake cars use either 695-14 or D70-14, while the Formula S uses E70-14. Even though all of them fit 14-inch rims and use bias-ply construction, they represent different tire formats and visual character within the Barracuda range.

That variation means the buyer should not assume one Barracuda size applies to every car from the same model year. The safest approach is to confirm the exact sub-model first, then verify the current wheel setup on the vehicle. That matters even more on older cars that may have seen wheel changes, brake upgrades, or previous restoration work over the years.

For a 1968 Plymouth Barracuda, 695-14 is a primary bias-ply tire size. It uses the older numeric sizing system and is offered in classic bias-ply form across several period-style product lines and sidewall treatments. Radial alternatives exist for buyers comparing constructions, but the original primary fitment itself remains a bias-ply size on a 14-inch rim.

That distinction matters because a radial equivalent and a bias-ply tire do not present the same sizing format or appearance. A buyer keeping a restoration-oriented look may stay with 695-14 bias-ply, while a driver considering radial behavior should compare wheel width, overall dimensions, and clearance before making the change rather than assuming every 14-inch radial alternative will suit the car.

For the 1968 Plymouth Barracuda, radial equivalents for 695-14 include 175R14, P185/75R14, and P195/70R14. Radial equivalents for E70-14 include 185R14, P195/75R14, and P205/70R14. In each group, the first option is an 80-series metric radial, the second is a 75-series P-metric radial, and the third is a 70-series P-metric radial.

Those equivalent sizes give the buyer several ways to compare a vintage bias-ply fitment with more modern radial sizing conventions. The recommended rim-width range shown for both primary sizes is 4 to 6 inches, but wheel diameter alone is not the whole story. Clearance, wheel width, and the actual stance of the car should still be checked before moving away from the original bias-ply format.

A 1968 Plymouth Barracuda owner considering a bias-ply-to-radial change should start by confirming the original primary size on the car, then comparing the intended radial equivalent against the wheel diameter and width. For 695-14 and E70-14, radial equivalents are available, but they remain alternative sizes rather than automatic one-for-one replacements for every Barracuda setup.

The practical checks are wheel width, overall tire dimensions, steering clearance, fender clearance, and the condition of the suspension and alignment. A car that has been lowered, fitted with aftermarket wheels, or altered during restoration deserves extra attention before a construction change. That way, the tire choice supports both the intended appearance and the way the car will actually be driven.

Start with the correct Barracuda size for the exact sub-model, because 1968 fitment spans 695-14, D70-14, and E70-14. From there, the main considerations are bias-ply construction, 14-inch rim compatibility, and the kind of presentation the car should have once mounted. For some sizes, the decision may also include whether to stay with the original-style bias-ply format or compare a radial equivalent.

After size and construction are settled, the finer points become sidewall treatment, tire series, and wheel-width suitability. A stock-looking driver may call for a very different tire than a Formula S with a muscle-era visual theme. Matching the tire to the car's intended use, current wheel setup, and overall restoration direction usually leads to a better result than choosing by looks alone.

1968 Plymouth Barracuda tires are available with several period-style sidewall treatments, including blackwall, narrow whitewall, dual-redline, redline, pin white stripe, and raised white letter styles. Availability depends on the tire size. The 695-14 selection is especially broad, while D70-14 and E70-14 focus more on performance-oriented looks such as redlines, stripes, and raised white letters.

That variety lets the tire do more than simply fit the car; it also influences how the Barracuda reads visually. A narrow whitewall leans toward a more traditional presentation, while redline or raised white letter tires push the look in a sportier direction. The best choice depends on the exact sub-model, wheel design, and whether the goal is understated restoration style or a stronger muscle-era statement.

Tires for the 1968 Plymouth Barracuda are available from BFGoodrich, US Royal, Firestone, and Goodyear, depending on the size. Brand availability changes across 695-14, D70-14, and E70-14, so the selection for one Barracuda setup may not match another. Each brand appears within specific vintage-style series rather than as a generic tire offering.

That means the brand decision is tied closely to size, series, and sidewall style rather than name alone. A buyer looking at 695-14 can compare a broader mix of manufacturers, while D70-14 centers on Firestone and E70-14 includes Firestone and Goodyear. It makes sense to narrow the search by the car's correct size first, then compare appearance and specifications within that size.

A period-style 1968 Plymouth Barracuda tire starts with the correct primary size for the exact configuration: 695-14 or D70-14 for Base and disc-brake cars, and E70-14 for the Formula S. From there, the most appropriate choice depends on whether the car should present as a traditional compact Plymouth, a sportier late-1960s muscle-era build, or a careful restoration-oriented driver.

Sidewall treatment and tire series do much of the visual work once the size is correct. Narrow whitewalls create a more conservative look, while redlines, pin white stripes, and raised white letters move the Barracuda toward a stronger performance-era appearance. If exact originality matters, it is wise to compare the tire choice against marque literature, period photos, or other vehicle-specific historical references.

On a restored 1968 Plymouth Barracuda, tire construction changes the visual character as much as the driving feel. A bias-ply tire preserves the vintage proportions and sidewall presentation associated with the car's original-era fitments, especially in sizes like 695-14, D70-14, and E70-14. That traditional construction tends to complement steel wheels, factory-style wheel covers, and muscle-era wheel designs naturally.

A radial alternative can still suit the car, but it often shifts the look because the sizing format and profile family differ from the original bias-ply convention. For owners building a road car, that may be acceptable or even desirable. For restoration-oriented work, construction should be considered part of the car's finished appearance, not just a mechanical replacement decision.

Yes, modifications can affect tire fitment on a 1968 Plymouth Barracuda even when the tire size itself is correct for the model. Aftermarket wheels, brake changes, altered ride height, and suspension updates can all change the space available around the tire. That matters with any of the Barracuda's 14-inch bias-ply sizes because wheel width and clearance are just as important as the sidewall marking.

A Barracuda that has been lowered or fitted with non-original wheels deserves a careful check before tires are chosen. Verifying wheel diameter, wheel width, steering clearance, and fender clearance helps prevent surprises once the tire is mounted. On an older car, it is also smart to confirm that alignment and suspension condition are good enough to support the intended tire setup.

Before driving a 1968 Plymouth Barracuda on new tires, inspect the wheels for correct diameter and condition, confirm proper mounting, and check inflation pressure. It is also worth looking over the suspension, steering components, and alignment, especially on a car that has spent long periods in storage. A fresh set of tires works best when the rest of the rolling chassis is ready for road use.

A short, careful initial drive is a good way to confirm that nothing rubs and that the car tracks properly. Listen for contact at full steering lock and look again for clearance around the fenders and inner wheelhouses afterward. That extra step is especially worthwhile on older Barracudas that may have changed wheels, springs, or brake components over time.

Collector-car tires on a 1968 Plymouth Barracuda should be checked regularly for air loss, tread wear, sidewall cracking, cuts, and bulges, even if the car is driven only occasionally. Low annual mileage does not stop tires from aging, and bias-ply tires deserve the same careful inspection as any other vintage vehicle component. Proper inflation also helps preserve shape and road manners between drives.

Storage conditions matter almost as much as mileage on a collector Barracuda. Keeping the car away from prolonged sunlight, excessive heat, moisture, and ozone sources can help protect the tires while it sits. Periodic inspections before each drive, along with a closer look before any longer trip, make it easier to catch age-related issues before they turn into roadside problems.
