1966 Ford Falcon Tires

The 1966 Ford Falcon uses four primary tire sizes: 650-13, 695-14, 735-14, and 775-14. All four are vintage numeric bias-ply sizes, and the correct one depends on the exact sub-model rather than the Falcon name alone. A 6 Cyl. Sedan uses 650-13, while other Falcon configurations move into 14-inch fitments.

The practical step is identifying the exact Falcon body style or engine grouping and then confirming the wheel diameter already on the car. A 13-inch wheel limits you to 650-13 fitment, while the 14-inch cars still need closer checking because several sub-models can use more than one primary size.

A 1966 Ford Falcon uses either a 13-inch or 14-inch rim, depending on the sub-model and tire size. The 650-13 fitment is built around a 13-inch wheel, while 695-14, 735-14, and 775-14 are all 14-inch tire sizes. Rim diameter is one of the first things to verify before selecting tires.

Looking at the wheel itself is important because many Falcons have been changed over the years. If the car has replacement wheels, mixed spare-and-road wheel sets, or later components, the tire size that belongs on paper may not match the hardware on the vehicle today.

No, 1966 Ford Falcon sub-models do not all use the same tire size. The 6 Cyl. Sedan uses 650-13, the Wagon uses 775-14, and the 8 Cyl. Sedan, 8 Cyl. Sport Coupe, and Ranchero can use different 14-inch sizes depending on the configuration. That variation is a normal part of Falcon fitment for this year.

Sub-model identification matters because two Falcons from the same year can require different wheel diameters and different tire widths. Once the exact model is confirmed, tire choice becomes much simpler and you can focus on period-style appearance, brand preference, or whether a radial equivalent is worth considering.

On the 1966 Ford Falcon, 650-13 is a primary bias-ply tire size. It uses the older numeric sizing system, where the first number represents nominal section width in inches and the last number identifies the 13-inch rim. For the Falcon applications that use this size, bias-ply is the original fitment type represented here.

A radial alternative can still be considered, but it should be treated as an equivalent option rather than the same construction in a different name. The wheel width, the actual wheel on the car, and available clearance around the suspension and fenders should all be checked before changing construction.

Radial equivalents for 775-14 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. Those choices give a range of modern radial sizing formats while staying tied to the original 14-inch wheel diameter.

Each of those options needs to be checked against the Falcon’s actual wheel and the space available in the car or truck body style involved. The recommended rim-width range is 4-6 inches, but that does not replace checking the vehicle’s wheel width, steering clearance, and overall setup.

Start with the Falcon’s original bias-ply size and choose only from the radial equivalents tied to that specific size. Then confirm wheel diameter, wheel width, and the type of radial being considered, whether that is an 80-series metric radial, a 75-series P-metric, a 70-series P-metric, or a bias-look radial where available.

The next step is checking the car as it sits today, especially if it has replacement wheels, altered ride height, or suspension work. Clearance at full steering lock, fender space, and the overall visual proportion of the tire all matter when changing construction on a vintage Falcon.

A 695-14 tire for a 1966 Ford Falcon should first match the sub-model and the existing 14-inch wheel setup. After that, the main differences come from brand, tire series, sidewall style, and rim-width specification. In this size, choices include BFGoodrich, US Royal, and Goodyear offerings with blackwall, narrow whitewall, dual-redline, and raised white letter treatments.

Selection usually comes down to how the Falcon is being used and how period-oriented you want it to look. A simple blackwall gives a clean traditional appearance, while redline, whitewall, or Blue Streak styles create a more distinct visual character, so the right choice depends on the car’s intended presentation.

Sidewall choices for 1966 Ford Falcon tires vary by size, but the overall selection includes blackwall, narrow whitewall, wide whitewall, dual-redline, redline, goldline, blueline, raised white letter, and raised white letter with Blue Streak styling. Not every Falcon size gets every sidewall treatment, so the look available depends on the exact tire size being used.

That means sidewall style should be chosen only after the correct fitment is confirmed. A 650-13 setup leans toward whitewall choices, while 695-14 and 775-14 open the door to more appearance-driven options. Matching the tire’s look to the car’s restoration theme usually matters as much as the basic size.

Tires for the 1966 Ford Falcon are available from Coker Classic, US Royal, BFGoodrich, Firestone, and Goodyear, depending on the size involved. Brand availability changes across the four primary fitments, so a Falcon using 650-13 sees a different mix than one using 775-14. Some sizes also include multiple tire series within the same brand family.

The smartest way to compare brands is within the exact size your Falcon requires. Once that is settled, look at sidewall style, rim-width specification, and the overall presentation each series offers. Brand choice is most useful when it helps narrow the appearance and fitment details that actually matter for the vehicle.

A period-style 1966 Ford Falcon tire starts with the correct primary size for the exact sub-model, then moves to the sidewall treatment that best matches the car’s intended presentation. Since all primary Falcon fitments here are bias-ply, staying with a bias-ply tire is the most natural path when the goal is a traditional vintage look.

Whitewall, blackwall, redline, goldline, and blueline choices can all change the personality of the car even when the fitment is correct. If exact originality matters, compare the tire choice against marque references, photos, or restoration records for that specific Falcon configuration rather than relying on appearance alone.

Tire construction has a visible effect on a restored 1966 Ford Falcon because the car’s primary fitments are bias-ply, and that construction carries the older shape and stance most buyers associate with mid-1960s presentation. A modern radial equivalent can change the visual character even when it remains tied to the same general size category.

That does not automatically make one approach right and the other wrong. A restoration focused on period-style appearance often stays bias-ply, while a road-use-focused build may consider a radial equivalent. The important part is choosing with both the Falcon’s look and the actual wheel setup in mind.

Yes, modifications can affect tire fitment on a 1966 Ford Falcon even when the tire size itself is correct for the original application. Aftermarket wheels, changes in wheel width, suspension lowering, spring replacement, brake conversions, or body alterations can all change the space available for a vintage-size tire or radial equivalent.

That is why an owner should check the car as it sits today instead of assuming every Falcon still matches factory wheel and suspension dimensions. Turning clearance, fender clearance, and the relationship between the tire and the wheel are the most important areas to review before mounting a new set.

Before driving a 1966 Ford Falcon on new tires, inspect the wheels for the correct diameter and condition, confirm lug hardware is secure, and make sure the tires are inflated properly for their intended use. It is also worth checking for rubbing at the front suspension, steering stops, and fender openings once the tires are mounted.

A short test drive should be followed by another look at clearance and air pressure, especially on a Falcon that has sat for long periods or has older suspension parts. Uneven ride height, worn bushings, or alignment issues can show up quickly with fresh tires and should be addressed early.

Collector-car tires on a 1966 Ford Falcon should be inspected regularly for air loss, tread wear, sidewall cracking, cuts, and bulges even if the car is driven only occasionally. Low annual mileage does not prevent age-related deterioration, so condition matters as much as tread depth on a vintage vehicle.

Storage also plays a major role in tire life. Keeping the Falcon away from prolonged sunlight, moisture, heat sources, and ozone-producing equipment helps preserve the rubber, and periodic pressure checks are important because a parked collector car can lose air gradually without obvious warning.
