The 1975 Ford E-100 Club Wagon came from an era when full-size vans were doing family-hauler, shuttle, and light-duty utility work all at once. That matters when choosing tires today, because this Club Wagon uses 15-inch fitments that span both traditional bias-ply sizing and a period radial option, depending on the exact configuration. Primary sizes include G78-15, H78-15, and HR78-15, so the first step is confirming the sub-model and construction you want to run. Available choices range from wide whitewall bias-ply tires to blackwall truck-style designs, with radial equivalents also available for the bias-ply sizes. For restoration-minded owners and drivers alike, appearance, wheel compatibility, and intended road use all deserve a careful look.
Which Tire Size Is Right for The 1975 Ford E-100 Club Wagon
Three primary tire sizes apply to the 1975 Ford E-100 Club Wagon, and the right one depends on the exact sub-model and whether the van is running a bias-ply or radial fitment. All three sizes use a 15-inch rim, so the key step is identifying the correct Club Wagon configuration first. From there, the decision shifts to construction, sidewall style, and whether a period-style bias-ply tire or a radial-format option better matches the van’s use and appearance.
G78-15 is a vintage alphanumeric bias-ply size in which the letter and series designation indicate the tire’s size class and profile family, while the 15 identifies the wheel diameter. On the 1975 Ford E-100 Club Wagon, it represents a traditional bias-ply fitment with the upright look and period sizing language many vintage van owners expect. Available choices include Coker Classic wide whitewall versions and an STA Super Traxion blackwall with a more truck-oriented character. This size is worth evaluating when the van’s exact sub-model calls for it and the goal is to stay close to a traditional 1970s tire presentation.
H78-15 is also a vintage alphanumeric bias-ply size, with the H designation placing it in a larger size class than G78 and the 15 marking a 15-inch rim. For the 1975 Ford E-100 Club Wagon, this is a core bias-ply fitment across several sub-models and gives buyers a broad period-style selection. Choices include Coker Classic wide whitewall tires in different whitewall widths as well as an STA Traxion blackwall with a more utilitarian truck look. This size makes sense when the van’s configuration uses H78-15 and the owner wants to compare traditional appearance against work-oriented styling.
HR78-15 is an alphanumeric radial size, where the R identifies radial construction within the vintage sizing system and the 15 refers to the wheel diameter. On the 1975 Ford E-100 Club Wagon, it serves buyers who want a primary radial-format fitment rather than converting from a bias-ply size to a modern equivalent. Its role is especially important on sub-models where both H78-15 and HR78-15 are associated with the van, making construction choice part of the decision. Before choosing it, confirm the wheel setup and overall tire plan so the radial selection matches the van’s intended use.
Sub-model fitment is not identical across the 1975 Ford E-100 Club Wagon range, even though every covered configuration uses a 15-inch rim. Checking the exact passenger and GVWR configuration matters first, because one sub-model includes G78-15 while the others center on H78-15 or HR78-15.

1975 Ford E-100 Club Wagon 6 Cyl. (5 Passenger)
The 6-cylinder 5-passenger Club Wagon has the widest fitment range here, with G78-15 and H78-15 bias-ply options as well as HR78-15 radial. That makes this sub-model especially important to verify carefully, since both size and construction can affect the direction of the tire search.
The 6-cylinder 8-passenger Club Wagon uses H78-15 in bias-ply form or HR78-15 in radial form on a 15-inch wheel. Tire selection here is more straightforward, with the main decision centered on preserving a traditional bias-ply look or choosing the radial-format alternative.
1975 Ford E-100 Club Wagon 8 Cyl. (5 Passenger) (GVWR 5500 & 5600)
This 8-cylinder 5-passenger Club Wagon with 5500 and 5600 GVWR uses H78-15 bias-ply or HR78-15 radial sizing. The practical choice is less about multiple wheel diameters and more about matching the van’s use, appearance goals, and wheel setup to the construction being considered.
1975 Ford E-100 Club Wagon 8 Cyl. (5 Passenger) (GVWR 5700 & 5900)
This higher-GVWR 8-cylinder 5-passenger Club Wagon also uses H78-15 bias-ply or HR78-15 radial sizing on a 15-inch rim. Buyers in this group should focus on confirming the existing wheel arrangement and then comparing construction, sidewall style, and product character within the correct fitment.
Bias-Ply to Radial Tire Conversion for the 1975 Ford E-100 Club Wagon
G78-15 and H78-15 each have four radial-equivalent paths to consider. For G78-15, the equivalents are 205R15 as an 80-series metric radial, P215/75R15 as a 75-series P-metric radial, P225/70R15 as a 70-series P-metric radial, and 710R15 as a bias-look radial. For H78-15, the equivalents are 215R15, P225/75R15, P235/70R15, and 760R15 in those same categories. These options vary by sizing convention and profile style, with the bias-look radial aimed at a more traditional presentation. A 6-8 inch rim-width range is associated with both groups, and wheel compatibility, overall dimensions, and clearance should still be checked before changing sizes.

Best 1975 Ford E-100 Club Wagon Tires for Sale
Available 15-inch choices for the 1975 Ford E-100 Club Wagon include Coker Classic and STA tires in G78-15 and H78-15. Buyers can compare wide whitewall and blackwall styles, traditional Coker Classic Bias Ply designs, and truck-oriented Super Traxion or Traxion series options.
Owners usually need to sort out the correct 15-inch size first, then decide between bias-ply and radial-style fitment. The questions below focus on sub-model differences, equivalent sizes, sidewall choices, restoration appearance, and practical road-use checks.
Tire Size & Fitment
What tire size fits a 1975 Ford E-100 Club Wagon?
The 1975 Ford E-100 Club Wagon uses G78-15, H78-15, or HR78-15, depending on the exact sub-model. G78-15 and H78-15 are bias-ply sizes, while HR78-15 is an alphanumeric radial. All of these fitments are built around a 15-inch rim, but the right size is tied to the van’s passenger and GVWR configuration rather than the model name alone.
That means the first job is identifying the exact Club Wagon version before choosing a tire. A 6-cylinder 5-passenger van has a broader fitment range than the other covered configurations, while the 8-passenger and V8 versions center on H78-15 or HR78-15. If the van has replacement wheels or past suspension work, confirm the actual wheel setup before selecting a tire.
What size rim does a 1975 Ford E-100 Club Wagon use?
The covered tire fitments for the 1975 Ford E-100 Club Wagon all use a 15-inch rim diameter. That includes G78-15, H78-15, and HR78-15. Even though the tire sizes differ by sub-model and construction, the rim diameter itself stays consistent across the fitments shown here.
Rim diameter is only part of the fitment picture, so it should not be the only thing checked. Wheel width still matters, especially when comparing bias-ply tires with radial equivalents or when the van no longer has its original wheels. Measuring the wheel and verifying clearance at the fenders and steering components is a smart step before mounting a new set.
Why does the 1975 Ford E-100 Club Wagon have more than one tire size?
More than one tire size appears because the 1975 Ford E-100 Club Wagon was offered in different passenger and GVWR configurations, and those variations do not all share the same fitment path. Some use H78-15 or HR78-15, while the 6-cylinder 5-passenger version also includes G78-15 as part of its fitment range.
For a buyer, that means the van’s exact sub-model matters more than the badge on the nose. Choosing by year, make, and model alone can leave too much room for error when multiple sizes and constructions are associated with the same vehicle family. Confirm the exact configuration first, then compare sidewall style, construction, and product type within that correct size.
Bias-Ply & Radial Options
Is H78-15 a bias-ply or radial tire for the 1975 Ford E-100 Club Wagon?
H78-15 is a bias-ply tire size on the 1975 Ford E-100 Club Wagon. It uses the vintage alphanumeric bias-ply format, while HR78-15 is the radial-format counterpart that appears on several Club Wagon sub-models. That distinction matters because the letter-and-series format looks similar, but the added R in HR78-15 changes the construction type.
Construction choice affects more than the label on the sidewall. A buyer keeping a traditional period-style presentation may stay with H78-15 bias-ply, while someone seeking a primary radial-format fitment may look at HR78-15 where it applies. Wheel condition, wheel width, and overall clearance should still be confirmed before changing construction on a vintage van.
What radial tire sizes are equivalent to H78-15?
Radial equivalents for H78-15 include 215R15 as an 80-series metric radial, P225/75R15 as a 75-series P-metric radial, P235/70R15 as a 70-series P-metric radial, and 760R15 as a bias-look radial. These are alternative radial-format sizes associated with the H78-15 bias-ply fitment rather than additional primary OE-style sizes for the van.
Each of those equivalents uses a different sizing convention, so the choice is not just about finding any radial with a 15-inch rim. The recommended rim-width range tied to these equivalents is 6-8 inches, and the final decision should also account for actual wheel width, tire dimensions, and clearance around the van’s fenders and suspension before a conversion is made.
What should I check before converting my 1975 Ford E-100 Club Wagon from bias-ply to radial tires?
Start by confirming which primary bias-ply size the van uses, because the radial equivalents differ between G78-15 and H78-15. G78-15 maps to 205R15, P215/75R15, P225/70R15, and 710R15, while H78-15 maps to 215R15, P225/75R15, P235/70R15, and 760R15. Those options give the Club Wagon owner several radial directions to evaluate rather than a single one-size answer.
After choosing the correct equivalent family, inspect the wheels closely and verify actual rim width, wheel condition, and vehicle clearance. A van with changed wheels, altered ride height, or previous brake and suspension work deserves extra attention before any construction change. The goal is to match the radial choice to the wheel and vehicle setup, not to assume every equivalent behaves the same.
Choosing the Right Tire
What should I consider when choosing a G78-15 or H78-15 tire for a 1975 Ford E-100 Club Wagon?
Begin with the exact size the sub-model uses, then compare the tire’s construction, sidewall style, and intended character. On the 1975 Ford E-100 Club Wagon, G78-15 and H78-15 are bias-ply fitments, and the available products range from Coker Classic wide whitewall designs to STA blackwall truck-style tires. Those choices give the van a noticeably different visual tone.
Once the correct size is confirmed, pay attention to wheel compatibility and the way the van will actually be used. A restoration-oriented Club Wagon may call for a more traditional whitewall presentation, while a utility-minded build may lean toward a blackwall truck-style look. Comparing rim-width specs, load figures where given, and overall appearance helps narrow the right tire within the proper size.
What sidewall styles are available for 1975 Ford E-100 Club Wagon tires?
The available sidewall styles for the 1975 Ford E-100 Club Wagon include wide whitewall and blackwall, depending on the tire size and product line. Coker Classic offerings in G78-15 and H78-15 use wide whitewall styling, while STA options in those same sizes are available as blackwall truck-oriented designs. That creates a clear appearance split within the correct fitments.
Sidewall choice should match the van’s overall goal rather than be treated as a cosmetic afterthought. A whitewall can suit a restoration-minded or family-cruiser presentation, while a blackwall often fits a more utilitarian or period truck-inspired look. Since sidewall style does not change the need for proper fitment, always confirm the exact size and wheel compatibility before deciding mainly on appearance.
What brands offer tires for the 1975 Ford E-100 Club Wagon?
Coker Classic and STA both offer tires in the 15-inch fitments used on the 1975 Ford E-100 Club Wagon. Coker Classic covers G78-15 and H78-15 with wide whitewall bias-ply designs in the Coker Classic Bias Ply series, while STA supplies blackwall options through its Super Traxion and Traxion series. The brand mix gives buyers both passenger-style and truck-style visual directions.
Brand choice still comes after fitment confirmation, not before it. Once the correct size is established, compare the series character, sidewall treatment, rim-width specification, and any load information that applies to the tire being considered. That approach keeps the decision grounded in how the Club Wagon is equipped and used, rather than choosing a tire by brand name alone.
Restoration & Appearance
Which tire should I choose for a period-style 1975 Ford E-100 Club Wagon?
A period-style 1975 Ford E-100 Club Wagon usually starts with the correct primary size for the van’s exact sub-model, then stays within the traditional bias-ply look if appearance is the priority. That could mean G78-15 or H78-15, depending on configuration. Within those sizes, the available choices include wide whitewall passenger-style tires and blackwall truck-style tires, each giving the van a different 1970s character.
The right choice depends on whether the Club Wagon is being presented as a family cruiser, a utility van, or a restoration project with a specific visual direction. For owners pursuing exact originality, the final appearance decision should be checked against marque-club guidance, original photos, or vehicle-specific historical documentation. Size, construction, and sidewall style all shape how authentic the finished van will look.
How does tire construction affect the appearance of a restored 1975 Ford E-100 Club Wagon?
Tire construction changes both the look and the stance of a restored 1975 Ford E-100 Club Wagon. Bias-ply sizes such as G78-15 and H78-15 preserve the vintage sizing language and traditional presentation many restoration-minded owners want, while HR78-15 introduces a radial format within the period alphanumeric system. A bias-look radial can also retain more of an old-style visual impression than a modern P-metric radial.
That visual difference is one reason construction should be chosen early in the project rather than at the end. Sidewall shape, tread character, and the overall impression of the van can shift when construction changes, even if the wheel diameter stays the same. Buyers balancing appearance with road use often compare a traditional bias-ply setup against a radial alternative before settling on the final direction.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1975 Ford E-100 Club Wagon?
Yes, modifications can affect tire fitment on a 1975 Ford E-100 Club Wagon even when the tire size itself is correct for the sub-model. Aftermarket wheels, different wheel widths, altered offsets, suspension changes, brake conversions, or body modifications can all change the space available for the tire. That matters with both the primary bias-ply sizes and any radial equivalent being considered.
A van that has been lowered, lifted, or fitted with replacement wheels should be measured rather than judged by catalog size alone. Steering clearance, fender clearance, and the actual wheel dimensions deserve attention before mounting new tires. On an older van, even small changes in wheel setup can alter how comfortably a tire fits during turns, loading, and normal road use.
What should I inspect before driving a 1975 Ford E-100 Club Wagon on new tires?
Before driving a 1975 Ford E-100 Club Wagon on new tires, inspect the wheels, lug hardware, valve stems, and general wheel condition, then confirm that tire size and construction match the van’s actual setup. It is also smart to look over the steering and suspension for looseness or worn parts that could affect how the van tracks once fresh tires are installed.
After mounting, keep an eye on inflation, clearance, and any signs of rubbing during the first miles of use. A collector-era van may also have old alignment issues or wheel damage that only become obvious after new tires go on. Rechecking pressure, fastener torque where appropriate, and visible sidewall condition helps catch problems before a longer drive.
How should G78-15, H78-15, or HR78-15 tires on a collector 1975 Ford E-100 Club Wagon be maintained?
Collector-use tires on a 1975 Ford E-100 Club Wagon should be maintained with regular pressure checks, visual inspections, and careful storage habits. Whether the van is running G78-15, H78-15, or HR78-15, low annual mileage does not stop tires from aging. Sidewall cracking, bulges, cuts, uneven wear, or repeated air loss all deserve attention before the van is put back on the road.
Storage conditions matter almost as much as driving conditions on a vintage Club Wagon. Keeping the van away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the tires between outings. It is also wise to inspect them before every road trip, since collector vehicles often sit longer than daily drivers and can develop condition issues that are easy to miss.
