The 2002 Mazda Trucks B4000 sits in the compact pickup era when buyers still expected a truck to handle daily driving, light work, and weekend use without losing a straightforward body-on-frame character. Closely associated with the Ranger-based pickup market of its time, the B4000 can present two distinct tire fitment paths depending on configuration. The 4x4 uses 245/75R16 radial tires, while the DS 4x2 uses 235/75R15 radials. That creates a meaningful choice not just in size, but in wheel diameter, load-oriented truck tire style, and available sidewall presentation. Getting the right tire starts with confirming the exact sub-model and existing wheel setup.
Which Tire Size Is Right for The 2002 Mazda Trucks B4000
The 2002 Mazda Trucks B4000 uses two primary tire sizes, and the correct one depends on the sub-model. The first step is confirming whether the truck is a 4x4 on 16-inch wheels or a DS 4x2 on 15-inch wheels, because the tire size changes with rim diameter. Once that is settled, the decision shifts to the kind of radial tire you want, from truck-oriented raised white letter styling to more appearance-focused whitewall options in the 15-inch size.
245/75R16 is a metric radial size in which 245 is the nominal section width in millimeters, 75 is the aspect ratio, R identifies radial construction, and 16 is the wheel diameter in inches. On the 2002 Mazda Trucks B4000, this size is used on a 16-inch wheel and suits the truck-oriented fitment of the 4x4 configuration. Available choices in this size lean toward all-terrain styling, including BFGoodrich's All Terrain TA KO2 with raised white letter sidewalls. This size is the one to evaluate when keeping the 4x4's original wheel diameter and a more utility-focused tire presentation.
235/75R15 is a metric radial size with a 235-millimeter nominal section width, a 75-series profile, radial construction, and a 15-inch rim diameter. On the 2002 Mazda Trucks B4000, this size belongs to the DS 4x2 configuration and opens up a much broader range of tire styles than the 16-inch fitment. Available products include raised white letter and multiple whitewall treatments across brands such as BFGoodrich, American Classic, Maxxis, Coker Classic, Tornel, and Travelstar. This is the size to focus on when maintaining the 15-inch wheel setup while choosing between a more truck-like look or a more distinctive custom appearance.
Tire fitment changes by sub-model on the 2002 Mazda Trucks B4000, so identifying the exact configuration matters before comparing tires. The two covered versions use different wheel diameters, which means size selection starts with the truck's 4x4 or DS 4x2 setup rather than brand or sidewall preference.

2002 Mazda Trucks B4000 4x4
The 2002 Mazda Trucks B4000 4x4 uses a 245/75R16 radial tire on a 16-inch wheel. That points the selection process toward truck-oriented radial options and makes wheel-diameter confirmation especially important if the truck has had wheel or suspension changes over the years.
The 2002 Mazda Trucks B4000 DS 4x2 uses a 235/75R15 radial tire on a 15-inch wheel. That fitment gives you a wider range of appearance choices, including raised white letter, narrow whitewall, and wide whitewall styles, so the decision often comes down to the look you want as much as the size itself.
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.

Common 2002 Mazda Trucks B4000 tire questions usually come down to sub-model fitment, 15-inch versus 16-inch wheel setups, and how to choose between truck-style radial tires and more appearance-driven sidewall options.
Tire Size & Fitment
What tire size fits a 2002 Mazda Trucks B4000?
A 2002 Mazda Trucks B4000 uses one of two radial tire sizes depending on sub-model. The B4000 4x4 uses 245/75R16, while the B4000 DS 4x2 uses 235/75R15. Those are different primary fitments, and they also use different wheel diameters.
The practical first step is confirming whether the truck is a 4x4 or a DS 4x2, then checking the wheel diameter currently on the vehicle. A truck that has been changed to aftermarket wheels should be measured rather than assumed, because a 15-inch tire and a 16-inch tire are not interchangeable simply because they are both used somewhere within the B4000 range.
What size rim does a 2002 Mazda Trucks B4000 use?
The 2002 Mazda Trucks B4000 uses either a 16-inch or 15-inch rim depending on configuration. The 4x4 uses a 16-inch wheel with 245/75R16 tires, and the DS 4x2 uses a 15-inch wheel with 235/75R15 tires.
That rim difference is central to tire selection, because the tire size must match the wheel diameter exactly. If the truck has replacement wheels, verify the actual wheel size before ordering tires. It also helps to compare wheel width against the tire's approved rim-width range, especially if the B4000 has custom wheels or has been repurposed for a different style of driving.
Why does the 2002 Mazda Trucks B4000 have more than one tire size?
The 2002 Mazda Trucks B4000 has more than one tire size because different sub-models use different wheel and tire combinations. The 4x4 uses 245/75R16, while the DS 4x2 uses 235/75R15, so the fitment changes with the truck's specific configuration.
That means tire selection should start with the exact sub-model rather than the model name alone. A B4000 badge is not enough by itself to choose tires accurately. Wheel diameter, current wheel setup, and any suspension or appearance modifications should all be checked before moving from the fitment question to sidewall style, tread character, or brand preference.
Choosing the Right Tire
What should I consider when choosing a tire for a 2002 Mazda Trucks B4000?
Start with the correct size for the truck's configuration: 245/75R16 for the 4x4 or 235/75R15 for the DS 4x2. From there, compare the tire's intended character, sidewall style, and rim-width compatibility rather than looking at brand name alone.
The 16-inch fitment is centered on a more truck-oriented all-terrain presentation, while the 15-inch fitment opens the door to raised white letter, narrow whitewall, and wide whitewall choices. Buyers using the truck for utility may focus on load capacity and wheel match, while appearance-driven builds may place more emphasis on sidewall treatment and the overall visual balance of the tire on the truck.
What sidewall styles are available for 2002 Mazda Trucks B4000 tires?
Sidewall choice depends on tire size. In 245/75R16, the available fitment is presented with raised white letter styling. In 235/75R15, the range is much broader and includes raised white letter, narrow whitewall, and wide whitewall options.
That makes the DS 4x2 fitment especially flexible for owners who want the truck to lean toward stock truck character, custom cruiser styling, or a more restoration-inspired look. Sidewall appearance does not change the required tire size, so choose the correct fitment first, then compare the visual effect each sidewall treatment will have with the truck's paint, wheel style, and ride height.
What brands offer tires for the 2002 Mazda Trucks B4000?
Available brands for the 2002 Mazda Trucks B4000 include BFGoodrich, American Classic, Maxxis, Coker Classic, Tornel, and Travelstar. Brand choice depends partly on tire size, since 245/75R16 centers on BFGoodrich while 235/75R15 includes a wider multi-brand selection.
The best way to use brand choice is as one part of a larger comparison. Look at the tire series, sidewall style, approved rim-width range, and load specification that matches how the truck is used. On a B4000 with 15-inch wheels, the visual style may drive the decision more strongly, while the 4x4 fitment tends to keep the focus on truck-oriented radial character.
Restoration & Appearance
Which tire should I choose for a period-style 2002 Mazda Trucks B4000?
A period-style choice for a 2002 Mazda Trucks B4000 starts with keeping the correct size for the sub-model, then choosing a sidewall and tire series that suit the truck's intended look. The DS 4x2 in 235/75R15 offers the widest appearance range, including narrow and wide whitewall options, while the 4x4's 245/75R16 fitment stays more truck-focused.
That decision usually depends on whether the truck is being kept close to its original-era pickup character or styled as a custom cruiser. A whitewall can create a stronger visual statement, but exact originality should be checked against marque-specific references and the truck's own history. Size and wheel diameter still come first, since appearance should never override proper fitment.
How does tire construction affect the appearance of a restored 2002 Mazda Trucks B4000?
On the 2002 Mazda Trucks B4000, primary fitment is radial in both sizes, so construction changes are less about bias-ply versus radial and more about how the tire is styled. The visible difference comes mainly from tread character, sidewall treatment, and overall tire presentation within the correct radial size.
For a restoration-oriented truck, the choice between raised white letter, narrow whitewall, and wide whitewall can shift the visual tone considerably. A 4x4 often looks more at home with a truck-style sidewall, while a 15-inch DS 4x2 leaves more room for custom or retro-inspired looks. Matching the tire's appearance to the wheel design helps the finished truck look intentional rather than mixed-era.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2002 Mazda Trucks B4000?
Yes, modifications can affect tire fitment on a 2002 Mazda Trucks B4000 even when the size matches one of the original fitment paths. Aftermarket wheels, altered wheel width, suspension changes, or ride-height changes can all change how a 245/75R16 or 235/75R15 sits in the wheel opening.
The safest approach is to confirm the actual wheel diameter and width on the truck, then check clearance at the fenders, steering stops, and suspension through the full range of motion. A B4000 that has been lowered, lifted, or changed to different wheels deserves a closer inspection before settling on a tire, especially when moving between stock-style and more aggressive tread presentations.
What should I inspect before driving a 2002 Mazda Trucks B4000 on new tires?
Before driving a 2002 Mazda Trucks B4000 on new tires, inspect the wheels for correct diameter and condition, make sure the tires are inflated properly, and verify that the tires clear the body and suspension at full steering lock. Lug hardware and valve stems also deserve a careful look before road use.
It also helps to check alignment condition and the truck's general suspension health, since worn components can affect how the new tires wear and feel. After the first miles, recheck inflation and look for any contact marks or uneven settling. That is especially worthwhile on older trucks that may have seen wheel changes, replacement springs, or long periods of intermittent use.
How should tires on a collector-era 2002 Mazda Trucks B4000 be maintained?
Tires on a collector-era 2002 Mazda Trucks B4000 should be maintained with regular pressure checks, routine visual inspection, and protection from long periods of heat, sunlight, and moisture. Even a truck that sees limited mileage can develop issues such as sidewall cracking, flat spotting, cuts, or gradual air loss.
Use should guide the inspection routine. A B4000 that is mostly stored still needs attention before every drive, while a truck that is driven more often benefits from regular tread and wear-pattern checks. Clean storage, periodic movement, and prompt correction of alignment or suspension issues help preserve both truck-style all-terrain tires and more appearance-focused whitewall radials.
