The 1984 Mazda Trucks B2000 comes from the era when compact Japanese pickups had become everyday work trucks with a loyal following for their simple construction, manageable size, and honest utility. Buyers today often keep these trucks on the road as light-duty drivers, preserved survivors, or restoration-minded projects that still need to look right. This B2000 uses a 6.00-14 bias-ply tire on a 14-inch rim, giving the page a very focused fitment story. The real choice is less about multiple primary sizes and more about selecting the right period-style tire presentation for the truck and its intended use. That makes wheel condition, appearance goals, and overall setup worth checking before choosing a replacement.
Which Tire Size Is Right for The 1984 Mazda Trucks B2000
The 1984 Mazda Trucks B2000 uses one primary tire size: 6.00-14, a bias-ply fitment for a 14-inch rim. That same size is used across the covered Sundowner sub-models, so the main decision is not between multiple factory-style sizes, but between available tire designs and whether the truck still has the wheel and suspension setup that matches this traditional fitment.
Fit(s): Sundowner (Base), Sundowner SE-5, and Sundowner Sport
Construction: Bias Ply|Rim: 14 in
A 6.00-14 tire uses the older numeric bias-ply sizing system, where 6.00 refers to the nominal section width in inches and 14 identifies the rim diameter. On the 1984 Mazda Trucks B2000, this is a traditional bias-ply fitment that suits the truck's original-era tire format and visual character. Buyers familiar only with modern metric sizes should recognize that this code does not follow today's radial naming pattern. It is the size to evaluate when keeping the truck in a period-style configuration, provided the wheels, stance, and overall clearance remain consistent with the vehicle's intended setup.
Tire fitment is straightforward across the covered 1984 Mazda Trucks B2000 sub-models because each one uses the same primary size. Checking the exact sub-model still helps confirm that the truck remains on the expected 14-inch wheel setup before choosing a replacement tire.

1984 Mazda Trucks B2000 Sundowner (Base)
The 1984 Mazda Trucks B2000 Sundowner (Base) uses the same 6.00-14 bias-ply tire size as the other covered B2000 sub-models. That keeps selection focused on period-style replacement choices and on confirming that the truck still carries the correct 14-inch wheel arrangement.
The 1984 Mazda Trucks B2000 Sundowner SE-5 also uses the 6.00-14 bias-ply fitment. For this sub-model, tire selection comes down to choosing a tire that matches the truck's intended appearance and use while verifying wheel condition and overall fitment before road service.
The 1984 Mazda Trucks B2000 Sundowner Sport shares the 6.00-14 bias-ply tire size with the other covered versions of the B2000. That makes the practical task simple: confirm the existing wheels and choose a replacement tire that suits either a preservation-minded look or regular light-duty driving.
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)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Frequently Asked Questions
These FAQs focus on 1984 Mazda Trucks B2000 tire size, 14-inch rim fitment, bias-ply construction, period-style tire selection, and the wheel, suspension, and maintenance checks that matter before putting a compact vintage pickup back on the road.
Tire Size & Fitment
What tire size fits a 1984 Mazda Trucks B2000?
The 1984 Mazda Trucks B2000 uses a 6.00-14 tire. This is a numeric bias-ply size, and it is the primary fitment across the covered Sundowner, Sundowner SE-5, and Sundowner Sport sub-models.
That makes size selection relatively simple, but it is still important to confirm that the truck remains on 14-inch wheels and has not been changed to a different wheel or tire package over the years. Many older compact pickups have seen aftermarket wheel swaps, so matching the tire size to the actual wheel on the truck is the first step.
What size rim does a 1984 Mazda Trucks B2000 use?
The primary tire fitment for the 1984 Mazda Trucks B2000 uses a 14-inch rim. That rim diameter corresponds to the 6.00-14 tire size, where the final number in the size code identifies the wheel diameter.
Rim diameter should be confirmed before ordering tires, especially on an older pickup that may have changed hands several times. A truck can still look stock while wearing replacement wheels, and a tire sized for a 14-inch rim cannot be mounted on a different diameter wheel. Checking the wheel itself prevents an avoidable fitment mistake.
Do all 1984 Mazda Trucks B2000 sub-models use the same tire size?
Yes. The covered 1984 Mazda Trucks B2000 sub-models all use the same primary tire size: 6.00-14 in bias-ply construction. That includes the Sundowner (Base), Sundowner SE-5, and Sundowner Sport.
Shared fitment across these sub-models means the buying decision shifts away from trim-level size differences and toward the truck's current condition and intended presentation. Even with consistent listed fitment, it is still smart to inspect the wheels on the vehicle, because older light trucks are often modified with different rims, suspension changes, or non-original tire packages.
Choosing the Right Tire
What should I consider when choosing a 6.00-14 tire for a 1984 Mazda Trucks B2000?
Start with the correct primary size, which is 6.00-14, and make sure the tire matches the truck's bias-ply fitment and 14-inch rim diameter. On a compact pickup like the 1984 Mazda Trucks B2000, the right choice often depends on whether the goal is a preservation-minded look, a restoration-oriented appearance, or light-duty road use.
Wheel condition matters just as much as tire size. A replacement tire should be matched to the actual wheel on the truck, and the owner should also consider how the vehicle sits, whether the suspension has been altered, and how much originality matters. Choosing carefully helps keep both the look and the fitment in line with the truck's setup.
How do I choose between the available 6.00-14 tires for a 1984 Mazda Trucks B2000?
The most useful way to compare 6.00-14 tires for a 1984 Mazda Trucks B2000 is by construction style, visual presentation, and how closely the tire suits the truck's intended role. Since the fitment centers on one primary size, the differences usually come down to appearance and how traditional you want the truck to feel.
A B2000 kept as a survivor or restoration project may call for a more period-style tire presentation, while a truck used more regularly still needs the same size and wheel compatibility checked first. It also helps to inspect the wheels for age, damage, or prior changes so the selected tire works with the truck's actual hardware rather than its assumed original setup.
What rim-fitment details should I compare when choosing 1984 Mazda Trucks B2000 tires?
The key rim-fitment detail for the 1984 Mazda Trucks B2000 is the 14-inch wheel diameter required by the 6.00-14 tire size. Diameter comes first, because even a correctly styled tire will not work if it does not match the wheel's actual diameter.
Beyond diameter, inspect the wheels for condition, prior repairs, and any signs that the truck has been altered from its original-style setup. A small pickup can be especially sensitive to wheel changes that affect clearance at the fender or steering components. Confirming the real wheel on the truck helps prevent choosing a tire that looks right on paper but not on the vehicle.
Restoration & Appearance
Which tire should I choose for a period-style 1984 Mazda Trucks B2000?
For a period-style 1984 Mazda Trucks B2000, the starting point is the correct primary size and construction: 6.00-14 in bias-ply form. That keeps the truck within the traditional tire format associated with its original-era fitment and preserves the visual character of a compact pickup from the mid-1980s.
Appearance-focused buyers should also consider how the truck will be presented, whether as a preserved driver, a light restoration, or a more formal show-oriented project. Exact originality can depend on vehicle-specific history, so owners pursuing a highly exact restoration should compare tire choices against marque references, period photos, or other trusted vehicle-specific documentation before making a final selection.
Does correct tire fitment matter for a 1984 Mazda Trucks B2000 restoration?
Yes, correct tire fitment matters because tire size and construction have a strong effect on how a restored 1984 Mazda Trucks B2000 looks and sits. Using the proper 6.00-14 bias-ply format helps maintain the truck's traditional stance and keeps the overall presentation aligned with its era.
Fitment matters beyond appearance as well. The wrong diameter or an altered wheel setup can affect clearance and change the way the truck presents itself visually. Even on a driver-quality restoration, checking the wheel diameter and confirming that the truck still matches its intended tire format helps avoid a result that looks out of place or creates avoidable fitment issues.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1984 Mazda Trucks B2000?
Yes. Modifications can change what works on a 1984 Mazda Trucks B2000, even when the original-style fitment is 6.00-14 on a 14-inch rim. Aftermarket wheels, suspension lowering, spring changes, or body alterations can all influence clearance and the practical tire options available on the truck.
That is why the truck should be inspected as it sits today rather than assumed to be unchanged. A wheel of the same diameter can still differ in width or overall placement, and suspension changes can reduce room during turning or compression. Confirming the current setup helps keep the replacement tire aligned with the vehicle's real-world fitment needs.
What should I inspect before driving a 1984 Mazda Trucks B2000 on new tires?
Before driving a 1984 Mazda Trucks B2000 on new tires, inspect the wheels, lug hardware, valve stems, and the general condition of the suspension and steering components. On an older compact pickup, it is also wise to check for rubbing points, uneven ride height, and any signs that prior wheel or tire changes may have altered clearance.
Tire condition and vehicle condition work together. Even with fresh tires, cracked wheels, worn steering parts, poor alignment, or neglected brakes can affect how safely and smoothly the truck goes down the road. A quick inspection of pressure, mounting, and visible clearance at full steering lock makes the first road test much more informative.
How should 6.00-14 tires on a collector 1984 Mazda Trucks B2000 be maintained?
Collector-use 6.00-14 tires on a 1984 Mazda Trucks B2000 should be inspected regularly for air loss, cracking, cuts, bulges, and uneven wear. A truck that spends long periods parked still needs routine pressure checks, because aging and storage conditions can affect tire condition even when mileage stays low.
Storage habits matter on a vintage pickup. Keeping the truck away from prolonged sunlight, excess moisture, and ozone sources helps protect the tires, and occasional movement can help avoid flat spotting during long idle periods. Before road use, check pressure again and give the tires a close visual inspection, especially if the truck has been sitting for weeks or months.
