The 1974 Dodge Ramcharger arrived at a time when full-size sport utility vehicles were still closely tied to pickup-truck hardware and genuine work-duty use. That gives this early Ramcharger a tire story that is less about modern crossover convenience and more about matching the truck’s GVWR and intended character. Depending on configuration, the 1974 Dodge Ramcharger uses 700-15, E78-15, G78-15, H78-15, or L78-15 bias-ply tires on 15-inch rims. That opens the door to traditional blackwall and whitewall choices, truck-oriented tread series, and several radial-equivalent paths for some sizes. The right selection starts with the exact sub-model, then balances appearance, load-minded fitment, and how the truck will actually be driven.
Which Tire Size Is Right for The 1974 Dodge Ramcharger
The 1974 Dodge Ramcharger uses five primary tire sizes, and all of them are bias-ply fitments on 15-inch rims. The key step is identifying the exact GVWR-based sub-model or special package first, because tire size changes across the Ramcharger lineup. Once that is confirmed, the decision becomes choosing the right type of bias-ply tire for the truck’s look and use, or evaluating a radial equivalent where one is available.
A 700-15 size uses the older numeric bias-ply system, where the leading number refers to nominal section width in inches and the final number identifies a 15-inch rim. On the 1974 Dodge Ramcharger, this is a bias-ply truck fitment that appears across several sub-models, including the Sno Filter Package versions. Available choices include Firestone, BFGoodrich, and STA tires in series such as Firestone Classic Bias Ply, Silvertown Classic Bias Ply, Traxion, Super Transport, and Transport Highway, with blackwall and wide whitewall styles. This size deserves close attention when maintaining a more utility-oriented or truck-style presentation.
E78-15 uses the vintage alphanumeric bias-ply system, where the letter marks the size class, the 78 identifies the profile family, and the 15 is the rim diameter. For the 1974 Dodge Ramcharger, it is one of the smaller GVWR-related bias-ply fitments rather than a universal size across every version. Radial-equivalent options exist for buyers considering a modern sizing convention, even though the primary fitment remains bias-ply. This size should be matched carefully to the exact Ramcharger configuration before comparing replacement choices or moving toward a radial alternative.
G78-15 follows the same vintage alphanumeric bias-ply format, with the letter and series designating the tire family and the final number calling for a 15-inch rim. On the 1974 Dodge Ramcharger, this size appears on certain GVWR-based versions and keeps the truck within a period-style bias-ply fitment. Choices include Coker Classic and STA offerings, with wide whitewall and blackwall sidewall treatments in both passenger-style and truck-oriented series. It is a useful size to evaluate when appearance matters, but the truck’s specific setup still determines whether G78-15 is the correct primary fitment.
L78-15 is a larger vintage alphanumeric bias-ply size, with the 15 again denoting rim diameter and the letter-series combination defining the tire class. For the 1974 Dodge Ramcharger, this size is used on heavier GVWR-related configurations and remains a primary bias-ply fitment. Product choices span Coker Classic, BFGoodrich, and STA, with blackwall, wide whitewall, narrow whitewall, and dual-white-stripe options across both classic bias-ply and truck-oriented series. This size is especially relevant when the goal is to match a heavier-duty Ramcharger setup with the right visual style and load-minded tire category.
H78-15 is another vintage alphanumeric bias-ply size, combining a traditional size class with a 15-inch rim requirement. On the 1974 Dodge Ramcharger, it is tied to higher-GVWR applications rather than every sub-model, so it should be selected only after confirming the truck’s exact configuration. Available products include Coker Classic whitewall options and an STA Traxion blackwall truck tire, giving buyers a choice between a more restoration-oriented look and a more utilitarian presentation. This size also has radial-equivalent alternatives worth comparing if the truck’s wheel width and overall clearance need to be reviewed.
Tire fitment on the 1974 Dodge Ramcharger varies by GVWR classification and special-package application, so the sub-model matters immediately. Several versions share 700-15, but the companion size changes depending on the truck, making exact configuration confirmation the first step before choosing a replacement tire.

1974 Dodge Ramcharger (GVWR 4900)
The 1974 Dodge Ramcharger (GVWR 4900) uses a mix of 700-15, E78-15, and G78-15 bias-ply sizes on 15-inch rims. That means the tire decision is not just about rim diameter, but about matching the truck’s actual setup before comparing whitewall, blackwall, or radial-equivalent alternatives.
The 1974 Dodge Ramcharger (GVWR 5200) uses 700-15, G78-15, and L78-15 bias-ply fitments. Selection starts with verifying which of those sizes is on the truck now, then deciding whether the goal is a passenger-style vintage look or a more truck-oriented tire series.
The 1974 Dodge Ramcharger (GVWR 5600 & 6100) uses 700-15, H78-15, and L78-15 bias-ply tires on 15-inch rims. Buyers working with these heavier-rated versions should confirm the wheel and size already in service before choosing among classic sidewall treatments or truck-duty tread patterns.
The 1974 Dodge Ramcharger 4x4 w/Sno Filter Pkg. uses 700-15 bias-ply tires. With only one primary size attached to this package, the choice shifts toward selecting the right tire series, sidewall style, and truck-use character within that size.
The 1974 Dodge Ramcharger 4x4 w/Sno Filter Pkg. (Carrying Blade) also uses 700-15 bias-ply tires. That keeps size selection straightforward, but the owner should still compare wheel width, intended use, and whether a vintage whitewall or a more work-oriented blackwall tire better suits the truck.
Bias-Ply to Radial Tire Conversion for the 1974 Dodge Ramcharger
Several 1974 Dodge Ramcharger bias-ply sizes also have radial-equivalent options. E78-15 can be compared with 185R15 as an 80-series metric radial, P195/75R15 as a 75-series P-metric radial, and P205/70R15 as a 70-series P-metric radial, with a recommended rim-width range of 5 to 6 inches. G78-15, H78-15, and L78-15 each add metric, P-metric, and bias-look radial choices as well. Those alternatives keep the 15-inch rim format, but wheel width, overall dimensions, and vehicle clearance still need to be checked before changing construction or profile.

Best 1974 Dodge Ramcharger Tires for Sale
Available 1974 Dodge Ramcharger tires span Firestone, BFGoodrich, Coker Classic, and STA, with choices that range from classic bias-ply whitewalls to blackwall truck series such as Traxion, Super Traxion, Super Transport, and Transport Highway. The main comparisons are size, sidewall style, tire series, and rim-width compatibility.
Ramcharger tire questions usually come down to exact size by GVWR or package, what the older bias-ply sizing codes mean, whether a radial equivalent exists, and how to choose between whitewall, blackwall, and truck-oriented tire series on a 15-inch wheel.
Tire Size & Fitment
What tire size fits a 1974 Dodge Ramcharger?
A 1974 Dodge Ramcharger can use 700-15, E78-15, G78-15, H78-15, or L78-15 tires, depending on the specific sub-model. All of these are primary bias-ply fitments on 15-inch rims, and the exact size changes with GVWR classification or special-package application rather than applying across the full Ramcharger lineup.
The important next step is confirming the truck’s exact version before ordering tires. A Ramcharger with a different GVWR grouping or a Sno Filter Package application may not use the same companion size, so checking the wheel setup already on the vehicle is just as important as reading the sidewall code.
What size rim does a 1974 Dodge Ramcharger use?
The 1974 Dodge Ramcharger uses 15-inch rims with its primary tire fitments. That 15-inch rim diameter is shared across 700-15, E78-15, G78-15, H78-15, and L78-15, so the wheel diameter stays consistent even though the tire sizes vary by sub-model.
Rim diameter is only part of the fitment picture, especially on an older truck that may have seen wheel changes over the years. It is smart to verify the wheel width as well, since different Ramcharger tire options and radial equivalents can call for different width ranges even when the rim diameter remains 15 inches.
Why does the 1974 Dodge Ramcharger have more than one tire size?
The 1974 Dodge Ramcharger has more than one tire size because fitment varies by GVWR-rated sub-model and package application. Some versions use E78-15 or G78-15, others use H78-15 or L78-15, and several also share 700-15 as part of their fitment range.
That variation means tire selection should start with the exact truck, not just the year and model name. Two Ramchargers from the same year can both wear 15-inch tires but still require different primary sizes, so matching the vehicle’s specific configuration helps avoid choosing a tire that belongs to another version.
Bias-Ply & Radial Options
Is E78-15 a bias-ply or radial tire for the 1974 Dodge Ramcharger?
E78-15 is a primary bias-ply tire size for certain 1974 Dodge Ramcharger applications. It uses the older alphanumeric sizing format, where the letter and series designate the vintage tire family and the final 15 identifies the rim diameter.
That matters because a true E78-15 preserves the truck’s original-era construction style, while modern radial equivalents use different sizing conventions. Anyone comparing alternatives should confirm wheel width and overall clearance first, especially if the truck has different wheels than it left the factory with or has seen suspension changes over time.
What radial tire sizes are equivalent to G78-15 on a 1974 Dodge Ramcharger?
Radial equivalents for G78-15 include 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. The recommended rim-width range attached to those equivalents is 6 to 8 inches.
Each of those sizes offers a different modern sizing approach while staying within the 15-inch rim format. The metric and P-metric options reflect different profile conventions, while the bias-look radial is aimed at a more traditional visual presentation, so wheel width, truck stance, and clearance should all be reviewed before switching.
What should I check before converting my 1974 Dodge Ramcharger from bias-ply to radial tires?
Start by matching the radial equivalent to the Ramcharger’s exact primary tire size, since E78-15, G78-15, H78-15, and L78-15 do not share the same radial alternatives. The 15-inch rim diameter may stay the same, but the equivalent size, profile style, and recommended rim-width range can differ from one original bias-ply size to another.
A careful conversion also includes checking the actual wheel width on the truck, along with steering clearance, fender clearance, and overall tire space at full suspension movement. Older Ramchargers are often modified, so any aftermarket wheels, ride-height changes, or heavy-duty use plans should be considered before moving away from the original construction type.
Choosing the Right Tire
What should I consider when choosing a 700-15 tire for a 1974 Dodge Ramcharger?
A 700-15 tire for a 1974 Dodge Ramcharger should first be matched to the truck’s actual fitment, then compared by intended use and appearance. Available choices include classic bias-ply passenger-style options from Firestone and BFGoodrich, along with more truck-oriented STA series such as Traxion, Super Transport, and Transport Highway.
That makes 700-15 less about finding a single version of the size and more about picking the right character within it. Whitewall styles suit a more restoration-minded presentation, while blackwall truck tires may better match a utility look, and wheel-width compatibility should still be checked before settling on a specific product.
What sidewall styles are available for 1974 Dodge Ramcharger tires?
Sidewall choices for 1974 Dodge Ramcharger tires include blackwall, wide whitewall, narrow whitewall, and dual-white-stripe styles, depending on the tire size. Those treatments vary across 700-15, G78-15, H78-15, and L78-15, so sidewall selection is tied to the exact fitment rather than the model as a whole.
The practical effect is that appearance can change substantially even when the tire size stays correct. A whitewall or dual-stripe tire gives the Ramcharger a more styled vintage look, while a blackwall truck tire leans toward a work-duty presentation, so buyers should choose the sidewall after confirming the proper size for their sub-model.
What brands offer tires for the 1974 Dodge Ramcharger?
Tires for the 1974 Dodge Ramcharger are available from Firestone, BFGoodrich, Coker Classic, and STA, depending on size. Brand choice also overlaps with tire character, since some offerings are classic bias-ply whitewalls while others are more truck-oriented blackwall designs in utility-focused series.
Brand should be considered alongside size, sidewall style, and series rather than treated as the only decision point. A Ramcharger being restored for a traditional look may call for a different presentation than one meant to emphasize truck use, and those differences show up clearly once the correct tire size has been confirmed.
Restoration & Appearance
Which tire should I choose for a period-style 1974 Dodge Ramcharger?
A period-style 1974 Dodge Ramcharger build usually starts by staying with the truck’s correct primary bias-ply size, then choosing a tire whose sidewall and series match the intended look. Depending on size, that can mean a blackwall truck-style tire, a wide whitewall, a narrow whitewall, or a dual-white-stripe presentation.
The best visual match depends on whether the Ramcharger is being presented as a utility 4x4, a dressed-up sport utility, or a general vintage truck restoration. Exact originality should be checked against marque references or vehicle-specific documentation, but getting the size and construction right is the strongest foundation for an authentic-looking result.
How does tire construction affect the appearance of a restored 1974 Dodge Ramcharger?
Tire construction changes the visual character of a restored 1974 Dodge Ramcharger as much as the sidewall treatment does. The truck’s primary fitments are bias-ply sizes, so a bias-ply tire keeps the older sizing language and traditional presentation that many restorers expect to see on a full-size 1970s utility vehicle.
A radial equivalent can still be considered on sizes where one exists, but it shifts the look into a more modern sizing format unless a bias-look radial is available for that specific fitment. For appearance-focused builds, construction choice should be weighed alongside ride intent, wheel dimensions, and the overall style of the restoration.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1974 Dodge Ramcharger?
Yes, modifications can affect tire fitment on a 1974 Dodge Ramcharger even when the tire size itself is correct for the sub-model. Aftermarket wheels, different wheel widths, suspension lifts or lowering changes, and body or steering alterations can all change how much room is available for a vintage bias-ply tire or a radial equivalent.
That is especially important on a truck that may have been used hard or updated over the years. Checking actual wheel dimensions, front-end clearance at full lock, and tire space through suspension travel helps prevent choosing a size that matches the model range but conflicts with the truck’s current configuration.
What should I inspect before driving a 1974 Dodge Ramcharger on new tires?
Before driving a 1974 Dodge Ramcharger on new tires, inspect the wheels for correct diameter and sound condition, verify that the tire size matches the truck’s sub-model, and confirm adequate clearance around the fenders and steering components. It is also wise to look over valve stems, lug hardware, and any wheel damage or distortion.
A broader safety check makes sense on an older utility vehicle. Tire pressure, alignment condition, brake operation, and suspension wear all influence how a newly fitted set of tires will behave, and any truck that has sat for long periods deserves a slower, more deliberate road test before regular driving resumes.
How should 700-15 tires on a collector 1974 Dodge Ramcharger be maintained?
700-15 tires on a collector 1974 Dodge Ramcharger should be kept properly inflated, inspected regularly for sidewall cracking, cuts, bulges, and uneven tread wear, and monitored for air loss during storage. Because many older trucks are driven infrequently, condition matters just as much as tread depth, especially on bias-ply tires.
Storage habits have a big effect on long-term service life. Keeping the Ramcharger away from prolonged sunlight, excess heat, moisture, and ozone sources helps preserve the tires, while periodic inspection before each outing helps catch age-related issues early rather than discovering them once the truck is already back on the road.
