The 1984 Dodge Trucks Ram 50 sits in the compact pickup era when light-duty trucks were expected to handle everyday work while still being easy to maneuver and economical to run. Buyers today often approach one as a practical survivor, a restoration project, or a clean period mini-truck. Tire fitment on this model is not one-size-fits-all, because the Ram 50 appears with both a 6.00-14 bias-ply option and a 185R14 radial depending on sub-model. That creates a real choice between preserving an earlier-style tire presentation or staying with the radial setup used on other trims. The first step is matching the exact sub-model before comparing sidewall style, brand, and road-use priorities.
Which Tire Size Is Right for The 1984 Dodge Trucks Ram 50
The 1984 Dodge Trucks Ram 50 uses two different tire sizes, and the correct one depends on the specific sub-model. Both sizes mount on a 14-inch rim, but one is a bias-ply 6.00-14 and the other is a radial 185R14. The key decision is identifying whether the truck is a Custom, Royal, or Sport before choosing a tire style, sidewall treatment, or brand.
A 6.00-14 numeric bias-ply size uses the leading number to indicate nominal section width in inches, with the final number showing a 14-inch rim diameter. On the 1984 Dodge Trucks Ram 50, this size represents the bias-ply fitment and gives the truck a more traditional light-truck presentation than a later radial format. Its relevance is centered on maintaining the correct construction style for the sub-model that uses it rather than comparing among many modern product variations. This size should be selected only after confirming the truck is the sub-model equipped for 6.00-14 bias-ply tires.
A 185R14 Euro-metric radial uses 185 to indicate nominal section width in millimeters, R for radial construction, and 14 for the wheel diameter in inches. On the 1984 Dodge Trucks Ram 50, this is the radial fitment used on specific sub-models and it opens the door to several product choices in blackwall and narrow whitewall form. Available options include Michelin, Phoenix, and Vredestein, with series such as Michelin MXV and Sprint Classic. This size is the one to evaluate when the truck has the radial-equipped trim and the goal is balancing appearance, road use, and wheel compatibility.
Sub-model identification matters on the 1984 Dodge Trucks Ram 50 because tire fitment changes by trim. The Custom uses a different size and construction from the Royal and Sport, so choosing tires starts with confirming the exact version of the truck.

1984 Dodge Trucks Ram 50 Custom
The 1984 Dodge Trucks Ram 50 Custom uses the 6.00-14 bias-ply tire size. That makes this trim the one for buyers focused on retaining a traditional bias-ply fitment and checking that the existing 14-inch wheels still match the truck's original-style setup.
The 1984 Dodge Trucks Ram 50 Royal uses the 185R14 radial tire size. That gives this sub-model access to multiple radial tire choices, including blackwall and narrow whitewall options, while keeping the buyer focused on 14-inch wheel compatibility and intended use.
The 1984 Dodge Trucks Ram 50 Sport also uses the 185R14 radial tire size. Tire selection here is less about choosing between sizes and more about deciding among available radial products, sidewall appearance, and wheel-width compatibility for the truck's actual setup.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)

Tire Size & Fitment
What tire size fits a 1984 Dodge Trucks Ram 50?
The 1984 Dodge Trucks Ram 50 uses either a 6.00-14 bias-ply tire or a 185R14 radial, depending on sub-model. The Custom uses 6.00-14, while the Royal and Sport use 185R14. Both sizes are built around a 14-inch rim, but they are different sizing systems and different tire constructions.
That means the first step is confirming the exact trim level and checking the wheels actually on the truck today. A Ram 50 with replacement wheels, an older restoration, or mini-truck-style modifications may no longer match its original setup, so size, construction, and wheel dimensions should all be verified before choosing a tire.
What size rim does a 1984 Dodge Trucks Ram 50 use?
The 1984 Dodge Trucks Ram 50 uses a 14-inch rim with both of its primary tire sizes. The 6.00-14 bias-ply and the 185R14 radial are both built for a 14-inch wheel diameter, so the rim diameter itself stays consistent even though the tire sizing format changes by sub-model.
Rim diameter is only part of the fitment picture, especially on older compact trucks that may have been changed over the years. It still helps to inspect actual wheel width, confirm there are no aftermarket wheel swaps, and make sure the tire choice matches the truck's sub-model, construction type, and available clearance.
Do all 1984 Dodge Trucks Ram 50 sub-models use the same tire size?
No. The 1984 Dodge Trucks Ram 50 has sub-model variation in tire fitment. The Custom uses a 6.00-14 bias-ply tire, while the Royal and Sport use a 185R14 radial. Even though all three trims use a 14-inch rim, the tire sizes and constructions are not the same across the lineup.
That difference matters because a buyer cannot choose by wheel diameter alone. A truck badged as Royal or Sport should be evaluated around 185R14 radial options, while a Custom should be checked for its bias-ply setup. Looking at the sidewall of the current tires and confirming trim details helps avoid ordering the wrong size format.
Choosing the Right Tire
What should I consider when choosing a 185R14 tire for a 1984 Dodge Trucks Ram 50?
Start by confirming that the truck is a Royal or Sport, since those are the Ram 50 sub-models that use 185R14 radial tires. From there, compare the available brands, sidewall appearance, and wheel-width compatibility. In this size, choices include blackwall and narrow whitewall options from Michelin, Phoenix, and Vredestein.
The best choice depends on how the truck is being presented and driven. A blackwall generally suits a more understated driver look, while a narrow whitewall leans more vintage in appearance. It also helps to compare the wheel width against the tire's approved range and review load and general construction details before settling on one product.
What sidewall styles are available for 1984 Dodge Trucks Ram 50 tires?
For the 185R14 radial fitment used on the 1984 Dodge Trucks Ram 50 Royal and Sport, available sidewall styles include blackwall and narrow whitewall. Those choices appear across multiple products, giving the truck a noticeably different visual character even when the tire size stays the same.
Sidewall style should be chosen with the truck's intended presentation in mind rather than treated as a universal original-style answer. A narrow whitewall can give a more restoration-oriented or period-style look, while a blackwall keeps the appearance simpler. Matching sidewall treatment to the truck's trim, finish, and use usually leads to a more cohesive result.
What brands offer tires for the 1984 Dodge Trucks Ram 50?
The 185R14 radial size used on the 1984 Dodge Trucks Ram 50 Royal and Sport is available from Michelin, Phoenix, and Vredestein. Michelin appears in the MXV series, and Vredestein offers the Sprint Classic. Those brand choices give buyers more than one approach to a period-appropriate radial fitment.
Brand alone should not be the only deciding factor. It still makes sense to compare sidewall style, tire series, wheel-width compatibility, and the overall look you want on the truck. Once the correct sub-model and size are confirmed, the better comparison is how each tire fits the truck's appearance and driving intentions.
Restoration & Appearance
Which tire should I choose for a period-style 1984 Dodge Trucks Ram 50?
A period-style choice starts with the sub-model's actual fitment. The Custom uses a 6.00-14 bias-ply tire, while the Royal and Sport use a 185R14 radial. Keeping that original-style size and construction approach is usually the best starting point when the goal is to preserve the truck's era-appropriate look.
Appearance details can then be narrowed by sidewall style and series where choices exist, especially on the 185R14 radial fitment. Buyers seeking a highly accurate restoration should also compare against model-specific photos, literature, or marque knowledge before selecting a brand or sidewall treatment, since period-style and exact originality are not always the same thing.
How does tire construction affect the appearance of a restored 1984 Dodge Trucks Ram 50?
Tire construction changes more than road feel on a restored 1984 Dodge Trucks Ram 50; it also changes the truck's visual character. The Custom's 6.00-14 bias-ply fitment carries a more traditional look, while the 185R14 radial used on Royal and Sport trims presents the truck in a more modernized 1980s style.
That is why construction should be matched to the trim and restoration goal rather than chosen only by convenience. A truck restored for authentic period flavor may look more convincing with its proper size and construction format, while a driver-focused project may place more value on the available radial choices within the correct sub-model fitment.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1984 Dodge Trucks Ram 50?
Yes. Modifications can affect tire fitment on a 1984 Dodge Trucks Ram 50 even when the original tire size is known. Aftermarket wheels, changes in wheel width, altered offset, lowered suspension, or body and fender modifications can all change how a 6.00-14 or 185R14 tire sits on the truck.
That is especially important on compact pickups that were often personalized. A truck that started life as a Custom, Royal, or Sport may now have a different wheel and suspension package than it originally carried. Checking wheel dimensions, steering clearance, and fender space before choosing tires helps prevent fitment surprises.
What should I inspect before driving a 1984 Dodge Trucks Ram 50 on new tires?
Before putting a 1984 Dodge Trucks Ram 50 back into regular use on new tires, inspect the wheels, valve stems, lug hardware, and overall suspension condition. It also helps to verify inflation, look for any rubbing at full steering lock, and make sure the tires seat properly on the 14-inch rims being used.
Collector and low-use trucks deserve an extra look beyond the tires themselves. Brake condition, wheel bearings, alignment, and aged rubber parts in the front end can all affect how the truck behaves once new tires are installed. A short local road test is a smart way to confirm tracking, clearance, and air retention.
How should tires on a collector 1984 Dodge Trucks Ram 50 be maintained?
Tires on a collector 1984 Dodge Trucks Ram 50 should be inspected regularly for pressure loss, tread wear, cracking, cuts, bulges, and signs of uneven wear. Trucks that are driven infrequently can age their tires out before they wear them out, so condition matters just as much as remaining tread depth.
Storage habits also make a difference. Keeping the truck away from prolonged sun, moisture, excess heat, and ozone sources helps preserve the tires, whether it uses 6.00-14 bias-ply or 185R14 radial fitment. Rolling the truck periodically and checking pressure before every drive can reduce flat-spotting and catch small issues early.
