The 2006 Mazda Trucks B4000 came at the end of Mazda’s long-running compact pickup era, offering a practical midsize truck format with real day-to-day utility and a strong overlap with enthusiasts who still use these trucks for work, weekend driving, and light trail duty. Tire fitment on the 2006 Mazda Trucks B4000 depends on sub-model, with 235/75R15 on the Base and 255/70R16 on the SE, both in radial construction. That creates two distinct selection paths, from whitewall-style 15-inch options to an all-terrain raised white letter 16-inch choice. The key is matching the truck’s exact trim and wheel diameter before deciding between appearance, load capability, and intended road use.
Which Tire Size Is Right for The 2006 Mazda Trucks B4000
The 2006 Mazda Trucks B4000 uses two primary tire sizes, and the correct one depends on the truck’s sub-model and wheel diameter. The Base uses a 15-inch radial fitment, while the SE uses a 16-inch radial fitment, so the first step is confirming which trim and wheel setup the truck actually has before comparing tread style, sidewall treatment, or load-focused options.
235/75R15 is a metric radial size in which 235 identifies the nominal section width in millimeters, 75 is the aspect ratio, R denotes radial construction, and 15 is the wheel diameter in inches. On the 2006 Mazda Trucks B4000, this size is used on the Base sub-model and opens up a broad range of radial choices. Available options include BFGoodrich, American Classic, Maxxis, Coker Classic, Tornel, and Travelstar, with RWL, narrow whitewall, and wide whitewall sidewall styles. This size is the one to evaluate when the truck has 15-inch wheels and the owner wants either a traditional whitewall presentation or a more utility-oriented tire appearance.
255/70R16 is a metric radial size where 255 is the nominal section width in millimeters, 70 is the aspect ratio, R indicates radial construction, and 16 is the wheel diameter in inches. On the 2006 Mazda Trucks B4000, this size applies to the SE sub-model and centers the decision more tightly around the truck’s 16-inch wheel setup. The available product uses BFGoodrich’s All Terrain TA KO2 series with an RWL sidewall treatment. This is the size to pursue when the truck carries the SE wheel package and the goal is preserving the proper overall fitment direction for a 16-inch radial application.
Sub-model fitment matters on the 2006 Mazda Trucks B4000 because the covered trims do not share the same tire size or wheel diameter. Identifying whether the truck is a Base or an SE is the starting point before comparing sidewall style, tire series, or intended use.

2006 Mazda Trucks B4000 Base
The 2006 Mazda Trucks B4000 Base uses the 235/75R15 radial size. That gives this trim the widest range of appearance and product choices, including RWL, narrow whitewall, and wide whitewall options, so the decision becomes one of presentation, wheel compatibility, and how the truck will be used.
The 2006 Mazda Trucks B4000 SE uses the 255/70R16 radial size. Tire selection here starts with confirming the 16-inch wheel setup, then choosing within the available all-terrain style and load-focused characteristics that suit the truck’s actual driving needs.
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.

Owners of a 2006 Mazda Trucks B4000 usually need to sort out trim-specific tire size, 15-inch versus 16-inch wheel fitment, radial product choices, sidewall style, and the checks that matter before putting an older truck back into regular road use.
Tire Size & Fitment
What tire size fits a 2006 Mazda Trucks B4000?
Two tire sizes apply to the 2006 Mazda Trucks B4000, depending on sub-model. The Base uses 235/75R15, while the SE uses 255/70R16, and both are radial sizes tied to different wheel diameters.
The practical step is to confirm the truck’s exact trim and actual wheel setup before choosing a tire. A previous owner may have changed wheels, so the sidewall size on the current tires and the measured rim diameter should agree with the truck’s present configuration before moving on to tread or sidewall style.
What size rim does a 2006 Mazda Trucks B4000 use?
The 2006 Mazda Trucks B4000 uses either a 15-inch or 16-inch rim, depending on sub-model. The Base pairs with a 15-inch tire size, and the SE pairs with a 16-inch tire size.
Rim diameter is the first fitment check because a 15-inch tire cannot be mounted on a 16-inch wheel, and the reverse is equally true. Looking at the wheel itself, the current tire sidewall, and the truck’s sub-model helps prevent ordering the right tire size for the wrong wheel.
Do all 2006 Mazda Trucks B4000 sub-models use the same tire size?
No. The 2006 Mazda Trucks B4000 Base uses 235/75R15, while the 2006 Mazda Trucks B4000 SE uses 255/70R16, so tire fitment changes with the sub-model rather than staying uniform across the line.
That difference affects more than just the sidewall numbers. It also changes wheel diameter, product selection, and the type of tire presentation available, since the 15-inch size includes several whitewall choices while the 16-inch size is represented here by an all-terrain raised white letter option.
Choosing the Right Tire
What should I consider when choosing a tire for a 2006 Mazda Trucks B4000?
Start with the correct size for the truck’s sub-model and wheel diameter: 235/75R15 for the Base or 255/70R16 for the SE. From there, compare construction, rim-width compatibility, load figures, sidewall style, and whether the truck will be used mainly on pavement, for utility duty, or for a more appearance-driven build.
The 15-inch fitment offers a wider spread of choices, including classic-style whitewalls and an all-terrain option, while the 16-inch fitment is more narrowly focused. Matching the tire to how the truck is actually driven usually matters more than choosing by appearance alone, especially on a pickup that may still see regular work.
What sidewall styles are available for 2006 Mazda Trucks B4000 tires?
Sidewall choices for the 2006 Mazda Trucks B4000 include RWL, narrow whitewall, and wide whitewall, depending on tire size and product line. The 235/75R15 fitment has the broadest appearance range, while the 255/70R16 fitment is represented here by an RWL all-terrain tire.
That means the Base trim gives more flexibility for a custom, retro, or cruiser-style presentation, especially if a whitewall look is part of the build. The SE fitment stays more truck-oriented, so the visual decision is closely tied to preserving the proper wheel size and intended use of the vehicle.
What brands offer tires for the 2006 Mazda Trucks B4000?
Available brands for the 2006 Mazda Trucks B4000 include BFGoodrich, American Classic, Maxxis, Coker Classic, Tornel, and Travelstar. Most of that variety appears in the 235/75R15 size, while the 255/70R16 fitment is represented here by BFGoodrich.
Brand choice is best used as one part of a broader comparison rather than the only decision point. Once the correct size is confirmed, compare each tire’s series, sidewall treatment, rim-width specification, and load capacity to narrow the options in a way that suits the truck’s actual setup and purpose.
Restoration & Appearance
Which tire should I choose for a period-style 2006 Mazda Trucks B4000?
A period-style approach starts by keeping the correct tire size for the truck’s sub-model. On a Base model, 235/75R15 offers the broadest appearance range, including wide and narrow whitewall radials as well as a more truck-oriented RWL option, while the SE remains tied to 255/70R16.
The right choice depends on whether the goal is a stock-looking driver, a mild custom presentation, or a utility-focused truck that still respects the era. Exact originality questions should be checked against marque-specific references or surviving truck details, since correct size and a sympathetic appearance are not always the same thing.
How does tire construction affect the appearance of a restored 2006 Mazda Trucks B4000?
On the 2006 Mazda Trucks B4000, the primary fitments are radial, so construction changes are less about converting from an earlier tire type and more about the visual character of the available radial products. The main appearance differences come from sidewall treatment, tread style, and series character within the correct size.
A wide whitewall or narrow whitewall can push a Base model toward a more customized or nostalgic presentation, while an RWL all-terrain look keeps the truck visually closer to a utility or sport-truck theme. Construction should still match the intended wheel and use, but appearance is shaped most strongly by sidewall style here.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 2006 Mazda Trucks B4000?
Yes. Wheel changes, suspension alterations, lift or lowering work, and body or steering modifications can all affect tire fitment on a 2006 Mazda Trucks B4000, even when the tire size matches the truck’s original sub-model pattern.
A truck with aftermarket wheels may have different width or offset than stock, which can change sidewall clearance and steering sweep. Checking the actual wheel diameter, wheel width, and available space around the fenders and suspension is especially important before moving between tire styles or replacing a setup chosen by a previous owner.
What should I inspect before driving a 2006 Mazda Trucks B4000 on new tires?
Before road use, inspect wheel condition, valve stems, lug hardware, and general suspension and steering health along with the new tires themselves. Tire pressure, visible damage, uneven wear patterns, and proper wheel-to-tire match all deserve attention on a 2006 Mazda Trucks B4000.
An older pickup may also have alignment issues or worn front-end parts that show up quickly after a tire change. A brief check of air retention, tread seating, and clearance at full steering lock helps confirm that the new setup is working correctly before the truck is put back into normal daily or highway use.
How often should tires on a 2006 Mazda Trucks B4000 be inspected?
Tires on a 2006 Mazda Trucks B4000 should be inspected regularly, not only at service intervals. Monthly pressure checks and routine visual inspections for cracking, punctures, sidewall damage, or irregular wear are especially worthwhile on a truck that may alternate between long idle periods and heavier use.
Road-use demands can change quickly on a pickup, so tread condition and air pressure should be checked before longer trips, hauling, or rough-surface driving. Frequent inspection also helps catch alignment or suspension problems early, which protects both tire life and the truck’s stability once it is back on the road.
