1998 Mazda Trucks carried the compact pickup formula into the late 1990s with B-Series models that balanced everyday utility, manageable size, and strong ties to the broader small-truck market of the era. Buyers could choose from the work-minded B2500, the mid-range B3000, and the more powerful B4000, each with its own tire-size considerations. Across these three models, six radial sizes appear, with 225/70R14 and 225/70R15 shared across the full range while several other sizes are model-specific. The first step with 1998 Mazda Trucks is confirming your exact model and wheel diameter, then narrowing the choice to the size and sidewall style that best suits your truck.
Which Tire Size Is Right for Your 1998 Mazda Trucks
Six tire sizes are used across 1998 Mazda Trucks, and they do not all apply to every model. The main decision starts with confirming whether your truck uses a 14-inch or 15-inch wheel, then matching the exact radial size tied to your B2500, B3000, or B4000. Understanding that distinction before choosing a product saves time and helps you land on the right fit.
Year(s): 1998|Fit(s): B2500, B3000, B4000|Construction: Radial|Rim: 14 in
225/70R14 is a metric radial size with a 225-millimeter section width, a 70-series profile, and a 14-inch rim diameter. This shared size is available from Cooper and BFGoodrich in RWL, wide whitewall, and redline sidewall styles, with an S speed rating appearing on some products and load ratings reaching 1,675 pounds at 35 psi. It fits all 1998 Mazda Trucks models that use 14-inch wheels, so the choice here is mostly about appearance and intended use rather than construction type.
Year(s): 1998|Fit(s): B2500, B3000, B4000|Construction: Radial|Rim: 15 in
225/70R15 is a metric radial size that denotes a 225-millimeter section width, a 70-series profile, and a 15-inch rim diameter. This shared size is available from Goodyear, Cooper, and Michelin in RWL and blackwall form, and tube status and speed rating vary by product, with a W-rated tubeless Michelin XWX reaching a 168 mph ceiling while other offerings do not carry the same marking. It works across all 1998 Mazda Trucks models that use 15-inch wheels and suits buyers who want a common cross-model size with room to choose between factory-style lettering and a more understated blackwall look.
Year(s): 1998|Fit(s): B2500|Construction: Radial|Rim: 14 in
205/70R14 is a metric radial size with a 205-millimeter section width, a 70-series profile, and a 14-inch rim diameter. This size is specific to the B2500 rather than universal across 1998 Mazda Trucks, and it is available from Maxxis and BFGoodrich in narrow whitewall, RWL, dual-redline, and redline styles, with an S speed rating appearing on some products and load ratings reaching 1,433 pounds at 35 psi. It is the right choice for a B2500 owner who needs the narrower 14-inch fitment and wants flexibility in period-style sidewall appearance.
Year(s): 1998|Fit(s): B3000|Construction: Radial|Rim: 15 in
235/75R15 is a metric radial size with a 235-millimeter section width, a 75-series profile, and a 15-inch rim diameter. This size is specific to the B3000 and is available from BFGoodrich, American Classic, Maxxis, and Coker Classic in RWL, wide whitewall, and narrow whitewall styles, with an S speed rating appearing on some products and load ratings running as high as 2,271 pounds at 32 psi. It is a strong fit for B3000 owners who need a taller 15-inch truck size and want to choose between utility-oriented tread character and more restoration-inspired whitewall styling.
Year(s): 1998|Fit(s): B3000|Construction: Radial|Rim: 15 in
215/75R15 is a metric radial size that uses a 215-millimeter section width, a 75-series profile, and a 15-inch rim diameter. This size is specific to the B3000 and is available from BFGoodrich, Coker Classic, and Tornel in RBL, narrow whitewall, and wide whitewall styles, with an S speed rating appearing on some products and load capacities reaching 1,874 pounds at 32 psi. It suits B3000 owners who need a narrower 15-inch fitment and want a choice that ranges from truck-oriented sidewall treatment to more classic whitewall styling.
Year(s): 1998|Fit(s): B4000|Construction: Radial|Rim: 15-in rim
265/75R15 is a metric radial size with a 265-millimeter section width, a 75-series profile, and a 15-inch rim diameter. It is specific to the B4000 within the 1998 Mazda Trucks range, and the available product details here center on the size's role as the larger model-specific 15-inch option. Buyers considering this fitment should confirm the exact wheel and overall tire stance they want before moving deeper into product selection for a B4000.
Three Mazda truck models are covered for 1998. They share some overlap in common 14-inch and 15-inch radial sizes, but several fitments are tied to only one model, so identifying whether you have a B2500, B3000, or B4000 matters before choosing a tire size. Select your model below to narrow the fitment history and see the sizes that apply to your truck.
1998 Mazda Trucks B2500
The B2500 was the practical four-cylinder entry in Mazda's late-1990s pickup lineup, aimed at owners who wanted compact-truck utility without stepping up to the larger V6 models. Its tires mount on either 14-inch or 15-inch wheels depending on configuration, and it is the only model in the range that also uses the narrower 205/70R14 option.
The B3000 sat in the middle of the B-Series lineup and gave buyers V6 power with the same compact-pickup footprint that made these trucks popular for daily use and light-duty hauling. It spans both 14-inch and 15-inch wheel fitments, and it carries two of the year's model-specific 15-inch sizes in addition to the shared cross-range options.
The B4000 was the strongest regular-production B-Series offering for 1998, giving the compact Mazda pickup line its most robust V6 personality. Its tires mount on 14-inch or 15-inch wheels, and it alone uses the larger 265/75R15 size alongside the shared 225-series fitments.
Twenty-three products are available across six tire sizes for 1998 Mazda Trucks. 225/70R14 has four radial choices from Cooper and BFGoodrich in RWL, wide whitewall, and redline styles; 225/70R15 has four from Goodyear, Cooper, and Michelin in RWL and blackwall; 205/70R14 has four from Maxxis and BFGoodrich in narrow whitewall, RWL, dual-redline, and redline; 235/75R15 has four from BFGoodrich, American Classic, Maxxis, and Coker Classic in RWL, wide whitewall, and narrow whitewall; 215/75R15 has four from BFGoodrich, Coker Classic, and Tornel in RBL, narrow whitewall, and wide whitewall. Confirm your exact size first, since speed ratings can vary between products within the same size.
These answers focus on how 1998 Mazda Trucks split tire sizes across the B2500, B3000, and B4000, what the metric codes mean, which sidewall styles and brands are available, and what to check when a late-1990s pickup spends part of its life in collector-style use.
Size Basics & Fitment
What tire sizes fit 1998 Mazda Trucks vehicles?
1998 Mazda Trucks use six radial sizes across the B2500, B3000, and B4000: 225/70R14, 225/70R15, 205/70R14, 235/75R15, 215/75R15, and 265/75R15. The shared sizes are 225/70R14 and 225/70R15, which appear across all three models. The B2500 also uses 205/70R14, the B3000 also uses 235/75R15 and 215/75R15, and the B4000 also uses 265/75R15. Rim diameters are either 14 or 15 inches, and published rim-width ranges run from 5.00 to 8.50 inches depending on the exact size and tire.
That means year and make alone are not enough for a confident tire choice on 1998 Mazda Trucks. Start by confirming your model, then verify whether your truck is wearing 14-inch or 15-inch wheels before narrowing down to the exact size. If your truck uses one of the shared 225-series sizes, sidewall style and brand preference become the next decisions. If it uses a model-specific size, staying with the correct fitment avoids clearance, stance, and load-range surprises.
What does 225/70R15 mean on a 1998 Mazda Trucks tire?
On a 1998 Mazda Trucks tire, 225/70R15 is a metric radial size. The 225 is the nominal section width in millimeters, 70 is the aspect ratio, R identifies radial construction, and 15 is the wheel diameter in inches. On this year and make, 225/70R15 appears across the B2500, B3000, and B4000, making it one of the broadest shared fitments in the lineup.
Understanding that code helps separate actual fitment from appearance. A 225/70R15 tire is built for a 15-inch wheel, so it is not interchangeable with a 14-inch fitment even if the sidewall looks similar at a glance. Once the wheel diameter is confirmed, you can compare available choices by sidewall style, brand heritage, and speed-rating details such as the W-rated Michelin XWX versus more traditional truck and muscle-era lettered sidewalls in the same size.
Do all 1998 Mazda Trucks models use the same tire size?
No, not all 1998 Mazda Trucks models use the same tire size. Every model shares 225/70R14 and 225/70R15, but the B2500 also uses 205/70R14, the B3000 adds 235/75R15 and 215/75R15, and the B4000 uses 265/75R15. That split reflects the fact that the B-Series range covered more than one wheel and tire package even within a single model year.
The practical takeaway is simple: confirm the model first, then confirm the wheel diameter on the truck you actually own. A B3000 and B4000 may look similar at a glance, but they can require very different 15-inch sizes. If the truck has been restored, modified, or fitted with replacement wheels over the years, checking the current wheel and sidewall stamping before selecting a tire is the safest way to avoid choosing by assumption.
Buying the Right Tire
What sidewall styles are available for 1998 Mazda Trucks tires?
1998 Mazda Trucks tires come in a wide mix of sidewall styles depending on size. Across the range you can find blackwall, RWL, RBL, narrow whitewall, wide whitewall, redline, and dual-redline offerings. The shared sizes lean toward RWL and specialty passenger-style sidewalls, while the B3000's 235/75R15 and 215/75R15 open up more whitewall choices alongside truck-oriented sidewall treatments.
For a late-1990s Mazda pickup, plain blackwall or raised-letter styles usually feel closest to the truck's original era and market position, especially on everyday-driver builds. Whitewalls and redlines can still make sense when the owner wants a custom look, a throwback appearance, or a distinctive show presentation. The key is to choose a sidewall style that matches both the truck's wheel package and the overall direction of the build rather than treating every 1998 Mazda Trucks model the same.
What brands make tires for 1998 Mazda Trucks vehicles?
1998 Mazda Trucks are covered by several brands across the available sizes, including Cooper, BFGoodrich, Goodyear, Michelin, Maxxis, American Classic, Coker Classic, and Tornel. Brand availability changes by size: 225/70R14 comes from Cooper and BFGoodrich, 225/70R15 from Goodyear, Cooper, and Michelin, 205/70R14 from Maxxis and BFGoodrich, 235/75R15 from BFGoodrich, American Classic, Maxxis, and Coker Classic, and 215/75R15 from BFGoodrich, Coker Classic, and Tornel.
That variety gives 1998 Mazda Trucks owners room to match the tire to the truck's personality. Some choices lean toward raised-letter performance styling, some toward classic whitewall appearance, and others toward truck-duty tread character. It is usually smarter to choose the right size and sidewall look first, then compare brands within that size, because the available brand mix changes significantly between the shared 225-series fitments and the model-specific B3000 sizes.
What is the difference between BFGoodrich All-Terrain T/A KO2 and Coker Classic Star Series for 1998 Mazda Trucks?
For 1998 Mazda Trucks in 235/75R15 or 215/75R15, the BFGoodrich All-Terrain T/A KO2 and Coker Classic Star Series serve very different roles. In 235/75R15, the KO2 carries a 104S speed/service marking, supports 1,985 pounds at 50 psi, uses an RWL sidewall, and fits 6.0- to 7.0-inch rims, while the Star Series supports 2,271 pounds at 32 psi, uses a wide whitewall, and fits 6- to 8-inch rims. In 215/75R15, the KO2 carries a 100S marking with 1,765 pounds at 50 psi and an RBL sidewall, while the Star Series supports 1,874 pounds at 32 psi with a narrow whitewall and a 5.5- to 7-inch rim range.
The buyer choice comes down to style and intended character, not just dimensions. KO2 products speak more clearly to a truck-oriented look and service profile, while Star Series tires lean toward a classic visual treatment with whitewall presentation. On 1998 Mazda Trucks, that difference matters most on B3000 fitments, where the same nominal size can send the truck in either a utility-focused or a more nostalgic direction.
Fitting & Setup
What rim width do 1998 Mazda Trucks tires require?
Rim-width requirements for 1998 Mazda Trucks depend on the exact tire size and product. In 14-inch sizes, 225/70R14 tires fit widths from 6.0 to 8.0 inches, while 205/70R14 tires fit widths from 5.00 to 7.50 inches depending on the tire. In 15-inch sizes, 225/70R15 fits from 6.0 to 8.0 inches, 235/75R15 from 6.0 to 8.50 inches, and 215/75R15 from 5.5 to 7.5 inches. Those ranges are broad enough that two tires with the same sidewall size can still prefer slightly different wheel widths.
That is why wheel verification matters before mounting anything on 1998 Mazda Trucks, especially if the truck has aftermarket wheels or a replacement wheel from another Ranger- or B-Series-era application. The safest approach is to match the tire you want to the actual wheel width on the truck, not just the wheel diameter. Staying inside the manufacturer's approved width range helps preserve the intended tread shape, steering feel, and sidewall support.
Do 1998 Mazda Trucks tires require inner tubes?
Most 1998 Mazda Trucks tire products in these sizes are presented without a tube-type marking, and one 225/70R15 option is explicitly marked TL for tubeless use. That makes tubeless construction the normal expectation across these late-1990s radial truck and passenger sizes. No conflicting tube-type marking appears among the products where a tube designation is visible.
Even so, wheel condition still matters on an older truck. If your 1998 Mazda Trucks wheels are rusty, damaged, or have questionable bead seats, correct sealing can become a wheel issue rather than a tire issue. A clean, sound wheel and a fresh valve stem are part of the setup, and any owner working with older original wheels should inspect them closely before mounting new tires.
Maintenance, Storage & Longevity
How should I store a 1998 Mazda Trucks when the tires are fitted?
A stored 1998 Mazda Trucks should be kept away from direct sunlight, electric motors, welders, battery chargers, and other ozone-producing equipment that can age sidewalls prematurely. Clean, dry concrete is better than damp ground, and stable inflation pressure helps the tire carry the truck's weight correctly during storage. Because these are radial tires, they generally resist flat-spotting better than older bias-ply designs, but long static periods can still leave a temporary thump on the first few miles.
If the truck sits for months at a time, move it periodically or support it in a way that reduces continuous load on one tire contact patch. A breathable cover and a dark, cool garage go a long way toward preserving both rubber and sidewall cosmetics. On a collector-minded 1998 Mazda Trucks build, storage habits often matter as much as miles driven when you are trying to keep tires looking fresh and driving smoothly.
How long do tires on a 1998 Mazda Trucks typically last?
Tires on a 1998 Mazda Trucks should be judged more by age and condition than by mileage alone, especially on a truck that sees occasional use. A good rule is to begin careful annual evaluation once tires reach about five to seven years old, then treat the ten-year mark as a serious replacement point regardless of remaining tread. The DOT date code on the sidewall is the reference for tire age.
A lightly driven truck can still have old rubber that looks acceptable from a distance but has hardened compounds, sidewall cracking, or weakened internal structure. That matters on 1998 Mazda Trucks because many surviving examples are weekend trucks, hobby trucks, or low-mileage second vehicles. If age and condition point in different directions, age should carry real weight in the decision.
How often should tires on a 1998 Mazda Trucks be inspected?
Tires on a 1998 Mazda Trucks deserve a quick inspection before every drive and a more thorough look before any highway trip or longer outing. Check for sidewall cracking, cuts, bulges, punctures, irregular wear, and pressure loss. Pay attention to valve stems as well, because an aging stem can create the same kind of roadside problem as a damaged tire.
A truck that sits often needs this routine even more than a daily driver. Air loss can go unnoticed in storage, and a tire that looked fine a month ago may show new cracking once it is washed or moved into better light. On 1998 Mazda Trucks, consistent inspection is one of the simplest ways to catch age-related issues before they affect ride quality, handling, or trip confidence.
Restoration & Authenticity
What tires were originally fitted to the 1998 Mazda Trucks B2500?
A 1998 Mazda Trucks B2500 was originally part of an era when radial construction was standard, and the fitments associated with the model here are all radial sizes: 225/70R14, 225/70R15, and 205/70R14. That puts originality more in the realm of choosing the correct size, wheel diameter, and era-appropriate sidewall treatment than deciding between bias-ply and radial construction. Blackwall and raised-letter styles are generally the most natural visual match for a late-1990s compact pickup.
Factory tire choice could still vary by trim, package, market, or wheel option, so a serious restoration should compare the truck's door-jamb information, original literature, and surviving wheel setup. If the goal is show-level accuracy, confirm the exact size your truck carried when new before settling on a replacement. Marque clubs and original brochure material are still the best references when authenticity matters more than flexibility.
Does correct tire fitment matter for showing a 1998 Mazda Trucks?
Correct tire fitment matters on a shown 1998 Mazda Trucks because judges and knowledgeable enthusiasts notice whether the size, sidewall treatment, and overall stance suit the truck's year and trim level. A late-1990s pickup usually looks most authentic with a radial tire in the proper 14-inch or 15-inch fitment and a sidewall style that reflects how these trucks were commonly delivered, rather than a dramatic whitewall or specialty stripe unless the build intentionally follows a custom theme.
What counts as correct depends on the event. Some shows reward factory-authentic appearance, while others are more open to dealer-style accessories, period personalization, or regional custom trends. For 1998 Mazda Trucks, the safest path is matching the right size to the right model and choosing a sidewall style that does not fight the truck's era. If the truck will be judged, event rules and marque-specific guidance should drive the final call.
What is the difference between BFGoodrich Radial T/A and BFGoodrich Silvertown Radial for the 1998 Mazda Trucks?
For 1998 Mazda Trucks in 225/70R14 or 205/70R14, BFGoodrich Radial T/A and BFGoodrich Silvertown Radial mainly differ in sidewall presentation and some wheel-width details. In 225/70R14, the Radial T/A uses an RWL sidewall, carries a 98S marking, supports 1,675 pounds at 35 psi, and fits 6.00- to 7.50-inch rims, while Silvertown Radial versions use wide whitewall or redline styling, support the same 1,675 pounds at 35 psi, and fit 6.00- to 8.00-inch rims. In 205/70R14, the Radial T/A uses RWL with a 93S marking and a 5.00- to 7.00-inch rim range, while Silvertown Radial versions use redline or dual-redline sidewalls with a 5.50- to 7.50-inch range.
That makes the choice less about basic fit and more about visual direction. Radial T/A gives 1998 Mazda Trucks a sportier raised-letter look that suits late-20th-century wheels, while Silvertown Radial versions push the truck toward a more customized or nostalgia-inspired appearance. Owners should also pay attention to the slight rim-width differences, especially when working with factory steel wheels on one truck and aftermarket alloys on another.
Safety & Road Use
Are 1998 Mazda Trucks tires safe for highway driving?
1998 Mazda Trucks use modern radial sizes, and several products carry clear highway-capable speed markings. Examples include S-rated tires, which are rated to 112 mph, and a W-rated 225/70R15 Michelin XWX, which carries a 168 mph ceiling. Those ratings are far above normal legal highway use, so in ordinary driving the truck's brakes, suspension condition, alignment, and overall mechanical state are usually more important than the tire's ultimate speed ceiling.
Safe highway use still depends on choosing the correct size, maintaining proper inflation, and making sure the tires are not aged out or damaged. On 1998 Mazda Trucks, a fresh correctly sized radial is entirely suitable for regular road use when the rest of the vehicle is in good condition. The smartest approach is to treat the tire as one part of the whole system rather than assuming a speed symbol alone answers the question.
What inflation pressure should I use for 1998 Mazda Trucks tires?
Inflation pressure on 1998 Mazda Trucks depends on the exact tire size and the specific tire chosen. Examples include 225/70R14 products rated at 1,675 pounds at 35 psi, 225/70R15 products rated at 1,753 pounds at 35 psi, 205/70R14 products rated at 1,433 pounds at 35 psi, 235/75R15 products ranging from 1,985 pounds at 50 psi to 2,271 pounds at 32 psi, and 215/75R15 products ranging from 1,742 pounds at 35 psi to 1,874 pounds at 32 psi.
Those numbers are load-at-pressure ratings, not universal vehicle settings. The right place to start is the truck's original placard or owner's manual for the factory recommendation, then compare that with the tire maker's own load and pressure guidance for the exact tire you are using. On 1998 Mazda Trucks, avoid copying a pressure figure from one size to another, especially when moving between passenger-style 225-series tires and taller truck-style 75-series fitments.
What should I check before taking a 1998 Mazda Trucks on a longer drive?
Before a longer drive in a 1998 Mazda Trucks, inspect every tire for cracking, cuts, bulges, punctures, uneven wear, and correct cold inflation pressure. Check the spare as well, because a neglected spare on an older truck is often unusable when it is finally needed. A close look at valve stems, wheel condition, and tread depth belongs on the same checklist.
Tires are only one part of a proper pre-drive routine on a truck of this age. It also makes sense to confirm alignment feel, steering response, brakes, and suspension condition before committing to highway miles. If your 1998 Mazda Trucks has spent long periods parked, give the tires a short local drive first and recheck them afterward so you can catch vibration, pressure loss, or age-related issues before heading farther from home.
