A Mazda B2500 (1999–2006) uses a 6x139.7 PCD and a centre bore of 93.1 mm.
Any wheel must match the vehicle's PCD exactly: there is no tolerance, unless you use a PCD adapter.
Centre bore: the wheel must have a centre bore of 93.1 mm or more. If it is larger (as with most aftermarket wheels), add a hub centric ring wheel centre bore → 93.1 mm.
Offset: the original is ET30. Compare your future wheel with the offset calculator (your vehicle is already selected) to see how many millimetres further in or out it will sit.
Fixings: thread Ecrous - 12x1.50, tightened to 103 Nm. The nuts or bolts must have the same seat (conical, spherical or flat) as the wheel.
Vehicles with the same PCD and centre bore
Same 6x139.7 PCD and same 93.1 mm centre bore: wheels from these vehicles bolt on and centre on a Mazda B2500 without rings. Offset, width, diameter and caliper clearance still need checking.
Choose the vehicle the wheels come from: we compare the hub, then each original wheel to the millimetre.
Same PCD, different centre bore
These vehicles also use 6x139.7 but with a different centre bore: their wheels need a hub centric ring if their centre bore is larger than 93.1 mm, and will not fit if it is smaller.
A Mazda B2500 (1999–2006) has a PCD of 6x139.7: 6 studs or bolts spaced around a circle 139.7 mm in diameter.
Does a Mazda B2500 need a hub centric ring?
The centre bore (hub diameter) of a Mazda B2500 is 93.1 mm. A wheel with a larger centre bore is fitted with a hub centric ring that brings it down to the hub diameter. A wheel with a smaller centre bore cannot be fitted.
What offset (ET) for a Mazda B2500?
The recorded original offset is ET30. A lower ET pushes the wheel outwards, a higher ET pulls it inwards: check wheel well and caliper clearance before making any change.
What tightening torque for the wheels of a Mazda B2500?
The specified tightening torque is 103 Nm for Ecrous - 12x1.50 fixings. Tighten in a criss-cross pattern with a torque wrench and check the tightness again after about fifty kilometres.
Which vehicles have the same PCD as a Mazda B2500?
With the same PCD (6x139.7) and the same centre bore (93.1 mm), these include: Mazda BT50, Mazda B2600, Mazda E2000,2200, Ford Ranger. Offset, width and rim diameter still need checking for each vehicle.
