The 1976 Ford Squire came from the era when full-size wagons were expected to carry families, luggage, and highway miles with equal ease. Woodgrain-trimmed Ford wagons of the mid-1970s blended utility with a distinctly upscale look, so tire choice affects both stance and character. This Squire uses 15-inch radial fitments in JR78-15 or LR78-15 depending on sub-model and engine configuration. Available choices center on traditional-looking radial construction, including a bias-look radial in LR78-15 with a narrow whitewall presentation. The key is matching the correct size to the wagon's exact configuration while keeping wheel fit, appearance, and intended road use in balance.
Which Tire Size Is Right for The 1976 Ford Squire
The 1976 Ford Squire uses two primary tire sizes, and the right one depends on the wagon's exact sub-model. Both fitments are radial tires for 15-inch rims, so the first step is confirming whether the vehicle uses the configuration that takes JR78-15 or the one that requires LR78-15. Once that is settled, the decision shifts to choosing the tire style and construction presentation that best matches the wagon's appearance and driving plans.
JR78-15 is a vintage alphanumeric radial size in which the letter designates the tire's size class, the R identifies radial construction, the 78 refers to its profile family, and 15 indicates rim diameter. On the 1976 Ford Squire, this format reflects a period-style radial fitment for 15-inch wheels rather than a modern metric size. The main reason to choose this size is vehicle-specific fitment, since it applies only to certain Squire configurations. Before selecting it, confirm the wagon's exact sub-model and current wheel setup so the tire matches the intended application.
LR78-15 uses the same vintage alphanumeric radial system, with the letter marking the tire's size class, R showing radial construction, the 78 identifying the profile family, and 15 denoting rim diameter. For the 1976 Ford Squire, this size is relevant to the heavier-duty wagon fitment and is available in a Firestone Steel Belted 721 with a narrow whitewall, Wide Oval Radial series styling, and a bias-look radial presentation. It is the size to evaluate when maintaining a more traditional wagon appearance while staying with the correct 15-inch radial format.
Sub-model fitment matters on the 1976 Ford Squire because tire size is not the same across the covered wagon configurations. Identifying the exact engine-based sub-model is the first step before comparing tire choices, since one version can use either size while another uses only LR78-15.

Tire Size & Fitment
What tire size fits a 1976 Ford Squire?
A 1976 Ford Squire uses either JR78-15 or LR78-15, depending on the exact wagon sub-model. Both are vintage alphanumeric radial sizes for 15-inch rims, so the correct fitment is tied to the specific configuration rather than to the model name alone.
The practical first step is confirming whether the wagon is the 400 Eng. or 460 Eng. version, then checking the wheels currently on the vehicle. Many older wagons have seen wheel or tire changes over the years, so matching the tire to both the sub-model and the actual 15-inch wheel setup helps avoid ordering the wrong size.
What size rim does a 1976 Ford Squire use?
The 1976 Ford Squire uses 15-inch rims with its primary tire fitments. Both JR78-15 and LR78-15 are built around a 15-inch wheel diameter, which is the key wheel measurement that must match the tire before any other fitment detail is considered.
Rim diameter alone does not settle the whole decision, because the wagon also needs the correct tire size for its sub-model and wheel setup. It is smart to confirm the wheel diameter stamped on the wheel or verify it directly before mounting tires, especially on a collector vehicle that may no longer have its original wheels.
Why does the 1976 Ford Squire have more than one tire size?
The 1976 Ford Squire has more than one tire size because fitment varies by sub-model. The Wagon 400 Eng. is associated with JR78-15 and LR78-15, while the Wagon 460 Eng. uses LR78-15, so the model name by itself is not enough to choose the tire.
That variation means tire selection starts with vehicle identification rather than brand or sidewall style. Once the exact sub-model is confirmed, compare the current wheel setup to the intended tire size and make sure the wagon has enough clearance and the right overall setup for the tire being considered.
Choosing the Right Tire
What should I consider when choosing a LR78-15 tire for a 1976 Ford Squire?
Start with the basics: LR78-15 must be the correct size for the wagon's sub-model, and the tire must match a 15-inch wheel. From there, the meaningful differences are construction presentation, sidewall style, and rim-width compatibility, since available LR78-15 choices can emphasize a more traditional wagon look.
A Firestone LR78-15 is offered as a bias-look radial with a narrow whitewall, which makes appearance part of the decision as much as size. Buyers should also compare the wheel width on the vehicle to the tire's approved rim-width range and think about whether the goal is a restoration-oriented look, regular road use, or both.
What sidewall styles are available for 1976 Ford Squire tires?
For the 1976 Ford Squire, the available LR78-15 product uses a narrow whitewall sidewall style. That treatment suits the character of a mid-1970s full-size wagon and gives the tire a more traditional appearance than a plain blackwall presentation would.
Sidewall style affects how the wagon reads visually from the curb, especially on a vehicle with bright trim and simulated woodgrain. The right choice depends on whether the goal is a cleaner road-going look or a more restoration-minded presentation, but the sidewall still needs to be paired with the correct size for the wagon's specific fitment.
What brands offer tires for the 1976 Ford Squire?
Firestone is represented in the available 1976 Ford Squire tire selection, specifically in LR78-15. That product appears in the Steel Belted 721 line and Wide Oval Radial series styling, giving buyers a period-style branded option within the correct vintage radial size format.
Brand is only one part of the decision on a wagon like this. It still makes sense to confirm the correct tire size first, then compare the tire's visual treatment, construction style, and wheel compatibility so the final choice suits both the vehicle's configuration and the way it will be used.
Restoration & Appearance
Which tire should I choose for a period-style 1976 Ford Squire?
A period-style 1976 Ford Squire tire choice starts with the wagon's correct primary size, either JR78-15 or LR78-15 depending on sub-model. From there, a vintage-format radial with traditional styling is the natural direction, since it keeps the full-size wagon's stance and visual character closer to its original era.
LR78-15 is available in a bias-look radial with a narrow whitewall, which is especially relevant for a restoration-oriented presentation. Buyers pursuing exact originality should still compare their wagon against model-specific historical references, since correct appearance can depend on trim, equipment, and the way the particular vehicle was originally delivered.
How does tire construction affect the appearance of a restored 1976 Ford Squire?
Tire construction affects more than ride and road feel on a restored 1976 Ford Squire; it also changes the wagon's visual character. A vintage alphanumeric radial keeps the proper era-style sizing language, and a bias-look radial can add a more traditional profile presentation than a plainly modern-looking replacement tire.
That matters on a large 1970s wagon because the tires are a visible part of the vehicle's stance, especially with bright trim and whitewall-friendly styling. Construction should still be matched to the correct size and wheel setup, but appearance-conscious owners often notice the difference between a generic replacement look and a more restoration-minded tire presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1976 Ford Squire?
Yes, modifications can affect tire fitment on a 1976 Ford Squire even when the tire size is otherwise correct. Aftermarket wheels, wheel-width changes, altered ride height, suspension work, or body repairs can all influence clearance, steering travel, and how a JR78-15 or LR78-15 tire sits on the vehicle.
A wagon from this era may have changed hands many times, so it is worth measuring what is actually on the vehicle instead of assuming it remains stock. Checking wheel diameter, wheel width, and visible clearance around the fenders and suspension helps prevent fitment surprises before mounting a new set of tires.
What should I inspect before driving a 1976 Ford Squire on new tires?
Before driving a 1976 Ford Squire on new tires, inspect the wheels, valve stems, lug hardware, and overall suspension condition. It also makes sense to look for rubbing points, uneven wear clues from the old tires, and any signs that the wagon's steering or alignment needs attention.
A fresh tire cannot compensate for loose front-end parts, damaged wheels, or poor inflation habits. After installation, recheck air pressure, listen for rubbing on turns, and confirm that the tire clears the body and suspension under normal movement so the wagon is ready for safe road use.
How should 1976 Ford Squire tires be maintained for collector use?
Collector-use tires on a 1976 Ford Squire should be maintained with regular pressure checks, visual inspections, and careful storage habits. Even if the wagon is driven only occasionally, the tires should be examined for cracking, cuts, bulges, flat spotting, and slow air loss before each outing.
Long periods of sitting can age tires differently than frequent use, especially on a heavy full-size wagon. Keeping the vehicle away from prolonged sun, moisture, and ozone sources helps preserve the tires, and occasional movement can reduce stress from sitting in one position for too long.
