The 1998 Mazda Trucks B4000 sits in the compact pickup era when buyers wanted everyday truck usefulness without stepping into a full-size platform. As Mazda’s version of a proven light-truck formula, the B4000 could serve as a practical driver, a clean survivor, or a period pickup with just the right late-1990s stance. Tire fitment is not one-size-fits-all here, because this model uses 225/70R14, 225/70R15, or 265/75R15 radial tires depending on configuration. That creates meaningful choice in rim diameter, sidewall style, and tire series, especially in the 225 sizes. The right selection starts with confirming the exact sub-model and wheel setup before narrowing appearance and road-use priorities.
Which Tire Size Is Right for The 1998 Mazda Trucks B4000
The 1998 Mazda Trucks B4000 uses three primary tire sizes, and the right one depends on the exact sub-model and wheel diameter. Two sizes are used on the SE 4x2, while the SE 4x4 uses a larger 265/75R15. Before comparing tire styles or brands, confirm whether the truck has 14-inch or 15-inch wheels and make sure the current wheel setup still matches the intended fitment.
225/70R14 is a metric radial size where 225 identifies the nominal section width in millimeters, 70 is the aspect ratio, R indicates radial construction, and 14 is the rim diameter in inches. On the 1998 Mazda Trucks B4000, this size suits a 14-inch wheel setup and keeps the truck in a modern radial format rather than an older bias-ply convention. Available choices include RWL, wide whitewall, and redline sidewall treatments from Cooper and BFGoodrich across series such as Cobra Radial G/T, Radial T/A, and Silvertown Radial. It is the right size to evaluate only after confirming a 14-inch wheel on the appropriate B4000 configuration.
225/70R15 follows the same metric radial sizing convention, with 225 millimeters of nominal section width, a 70-series profile, radial construction, and a 15-inch rim diameter. For the 1998 Mazda Trucks B4000, this size opens up the broadest product selection, including blackwall, RWL, narrow whitewall, wide whitewall, pin-white-stripe, and redline presentations. Brands in this size include Goodyear, Cooper, Michelin, Maxxis, and BFGoodrich, with series such as Polysteel, Cobra Radial G/T, Michelin XWX, Classic Whitewall MA-1, Silvertown Radial, and Radial T/A. This size makes sense for owners who have confirmed a 15-inch wheel on the correct truck setup and want the widest appearance and brand variety.
265/75R15 is a larger metric radial size that uses a 265-millimeter nominal section width, a 75-series profile, radial construction, and a 15-inch rim. On the 1998 Mazda Trucks B4000, this size is associated with the SE 4x4 and represents a distinctly different fitment direction from the narrower 225-series tires used on the 4x2 version. Its larger dimensions make sub-model identification especially important before purchase, since the same 15-inch rim diameter does not mean every 15-inch size belongs on every B4000. Owners should confirm the truck’s 4x4 configuration, wheel width, and clearance before treating this as the correct fitment path.
Sub-model fitment matters on the 1998 Mazda Trucks B4000 because the covered configurations do not all use the same tire size. The first step is confirming whether the truck is an SE 4x2 or an SE 4x4, then matching that truck to the correct wheel diameter and tire size.

1998 Mazda Trucks B4000 SE 4x2
The 1998 Mazda Trucks B4000 SE 4x2 uses either 225/70R14 or 225/70R15 radial tires, so wheel diameter is the key detail to verify on this sub-model. Once the rim size is confirmed, the decision shifts toward brand, tire series, and sidewall appearance rather than basic construction type.
The 1998 Mazda Trucks B4000 SE 4x4 uses the larger 265/75R15 radial size, separating it clearly from the 225-series fitments used on the 4x2 version. That makes it important to confirm the actual 4x4 wheel and overall truck setup before selecting a replacement tire.
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.
Best 1998 Mazda Trucks B4000 Tires for Sale
Available 1998 Mazda Trucks B4000 tires vary most in the 225/70R14 and 225/70R15 sizes, where Cooper, BFGoodrich, Goodyear, Michelin, and Maxxis offer multiple series and sidewall treatments including blackwall, RWL, whitewall, pin-white-stripe, and redline.
Owners usually need to sort out three things on a 1998 Mazda Trucks B4000: the correct size for the exact sub-model, the wheel diameter already on the truck, and how available radial tires differ in brand, series, and sidewall style.
Tire Size & Fitment
What tire size fits a 1998 Mazda Trucks B4000?
The 1998 Mazda Trucks B4000 uses 225/70R14, 225/70R15, or 265/75R15 radial tires. The SE 4x2 uses either 225/70R14 or 225/70R15, while the SE 4x4 uses 265/75R15. Those are distinct primary fitments, not interchangeable choices for every B4000.
The practical first step is confirming the exact sub-model and the wheel diameter currently on the truck. A 15-inch wheel does not automatically mean either 225/70R15 or 265/75R15 is correct, because overall tire dimensions differ significantly. If the truck has been modified or fitted with different wheels over time, verify the actual setup before selecting a replacement tire.
What size rim does a 1998 Mazda Trucks B4000 use?
The 1998 Mazda Trucks B4000 uses either a 14-inch or 15-inch rim, depending on tire size and sub-model. The 225/70R14 fits a 14-inch rim, while both 225/70R15 and 265/75R15 fit 15-inch rims. Rim diameter is one of the most important details to confirm before ordering tires.
Checking the wheel itself matters because a B4000 may no longer be on its original wheel package. Once rim diameter is confirmed, compare wheel width with the tire being considered and make sure the tire size matches the truck’s actual configuration. That step helps avoid confusion between the two different 15-inch fitments used across the covered B4000 sub-models.
Do all 1998 Mazda Trucks B4000 sub-models use the same tire size?
No. The 1998 Mazda Trucks B4000 SE 4x2 uses 225/70R14 or 225/70R15 radial tires, while the SE 4x4 uses 265/75R15. Fitment changes by sub-model, so the correct tire is tied to the truck’s specific configuration rather than to the B4000 name alone.
That difference affects more than just the numbers on the sidewall. It also changes rim diameter in some cases and changes the overall tire dimensions being used on the truck. A buyer should confirm the sub-model, current wheel size, and whether any wheel or suspension changes have been made before treating another B4000 tire size as a suitable alternative.
Choosing the Right Tire
What should I consider when choosing a tire for a 1998 Mazda Trucks B4000?
Start with the correct primary size for the truck: 225/70R14, 225/70R15, or 265/75R15 depending on sub-model and wheel diameter. From there, compare construction, rim-width compatibility, load figures where stated, and the type of driving and appearance you want from the finished setup.
The 225-series sizes offer the most variety, so choices may come down to sidewall treatment, brand, or tire series rather than basic fitment alone. A truck kept close to a late-1990s street appearance may point one way, while a more restoration-oriented or personalized look may point another. Verifying wheel width and the truck’s present configuration keeps those style decisions grounded in proper fitment.
What sidewall styles are available for 1998 Mazda Trucks B4000 tires?
Sidewall choices for the 1998 Mazda Trucks B4000 include blackwall, RWL, narrow whitewall, wide whitewall, pin-white-stripe, and redline, depending on the tire size selected. Most of that variety appears in the 225/70R14 and especially the 225/70R15 sizes, where the product range is much broader.
That means sidewall styling can become a real part of the decision once the correct tire size is confirmed. RWL gives a sporty late-20th-century look, whitewall variations create a more custom or classic presentation, and blackwall keeps the appearance understated. The important thing is to choose the sidewall style only after the truck’s sub-model and wheel diameter are settled.
What brands offer tires for the 1998 Mazda Trucks B4000?
Available brands for the 1998 Mazda Trucks B4000 include Cooper, BFGoodrich, Goodyear, Michelin, and Maxxis, depending on tire size. The strongest brand variety appears in 225/70R15, while 225/70R14 also includes multiple brand options. Those choices span several tire series and more than one sidewall presentation.
Brand selection should come after confirming the right size, because not every brand appears in every B4000 fitment. Once the size is settled, compare the visual style, stated load figures where available, and wheel-width compatibility for the exact tire being considered. That approach keeps the purchase centered on fitment first and personal preference second.
Restoration & Appearance
Which tire should I choose for a period-style 1998 Mazda Trucks B4000?
A period-style 1998 Mazda Trucks B4000 starts with using the correct primary size for the truck’s exact configuration, then choosing a radial tire whose sidewall look suits the era you want to capture. On the 225 sizes, options such as RWL, blackwall, redline, and whitewall treatments create very different visual results.
Late-1990s compact pickups often look most natural when wheel diameter, tire profile, and sidewall style stay in balance with the truck’s original character. That does not make one treatment universally correct for every B4000, especially if the truck has custom influences. Owners pursuing strict originality should compare tire appearance against period photos, brochures, or marque-specific references before deciding.
Does correct tire fitment matter for a 1998 Mazda Trucks B4000 restoration?
Yes, correct tire fitment matters because it affects both appearance and the truck’s overall stance. A 1998 Mazda Trucks B4000 can use more than one primary size across its covered sub-models, so using the wrong size can change the visual proportion of the wheel opening and the way the truck sits.
Fitment accuracy also helps keep a restoration from mixing details that belong to different configurations. The right approach is to confirm the exact sub-model, verify whether the truck is on 14-inch or 15-inch wheels, and then choose the tire style that best supports the intended presentation. That is especially important when the truck is being returned from years of owner modifications.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1998 Mazda Trucks B4000?
Yes. Modifications such as aftermarket wheels, suspension changes, ride-height adjustments, or body alterations can change what works on a 1998 Mazda Trucks B4000 even when the tire size is otherwise associated with that model. This matters most where the truck already has multiple valid factory-type sizes across different sub-models and wheel diameters.
A changed wheel width or offset can alter clearance at the fender, steering components, or suspension. Lowering or lifting can create similar issues. Before choosing replacement tires, inspect the truck as it sits now rather than assuming it still matches its original configuration. That is the safest way to sort out whether the intended size still suits the actual truck.
What should I inspect before driving a 1998 Mazda Trucks B4000 on new tires?
Inspect the wheel diameter and wheel condition first, then confirm the new tire size matches the truck’s sub-model and current setup. Check for adequate clearance at full steering lock, proper inflation, secure valve stems, and any signs that suspension or alignment issues could affect tire wear once the truck is back on the road.
A B4000 that has sat for long periods also deserves a close look at brakes, shocks, bushings, and steering components. New tires cannot correct worn chassis parts, and those issues can quickly affect how the truck tracks and how the tires wear. A short, careful road test after installation helps confirm the setup before committing to regular driving.
How should tires on a collector 1998 Mazda Trucks B4000 be maintained?
Tires on a lightly used 1998 Mazda Trucks B4000 should be checked regularly for air loss, uneven tread wear, sidewall cracking, bulges, cuts, and changes in ride feel. Even a truck that sees only occasional use needs routine inspection, because age and storage conditions can affect tires long before tread depth becomes the issue.
Good collector-vehicle habits include keeping inflation consistent, moving the truck periodically, and storing it away from prolonged sunlight, excess heat, moisture, and ozone sources. A quick inspection before each drive is a smart routine, especially on a truck that is not driven weekly. That simple habit helps catch fitment or tire-condition problems before they become road-use problems.
