Isuzu D-Max 2nd gen (RT) wheel fitment

RT D-Max touring builds commonly use sixteen- or seventeen-inch wheels with all-terrain tyres. Moderate widths and positive offsets keep the fitment closer to the original wheels than deep-dish off-road sets.

6x139.7 bolt pattern · Centre bore not confirmed · Stock wheels: 16 × 6.5, 16 × 7, 17 × 7, 18 × 7 inch · Stock tyres: 245/70 R16, 255/65 R17, 255/60 R18

Starting points for a build. Read the notes with each setup, especially if your car is lowered or has different brakes.

17-inch touring

Front and rear: 17 × 8 inch, ET20 · 265/65 R17

Reported by an RT owner after the dealer checked clearance. Verify tyre coverage and full-lock clearance on your body style.

Wider aftermarket road / touring wheel

CalOffroad lists this D-Max wheel fitment with a 1,675 kg wheel rating. Tyre size is omitted because its guide does not confirm a complete tyre package; check coverage and suspension travel.

Width and offset guidance

Offset range

Check the exact setup

There is no confirmed range for this car yet. Compare a known wheel with your proposed size and measure both sides.

Common width limit

Measure before ordering

A maximum width has not been confirmed. Tyre shape, ride height and alignment all change the available space.

These figures belong to the setups described here. Combining the widest wheel with either end of the offset range does not guarantee a safe fit. For how ET moves the wheel in and out, read wheel offset explained; for how far the tyre can sit out, see flush, poke and tucked fitment.

Clearance notes

Centre bore is omitted: the consulted fitment tables disagree between 100.1 and 100.5 mm, while other guides quote still larger bores. Confirm the hub and the wheel's centring arrangement before ordering.
Isuzu's 2012–2017 and 2017 handbooks specify 120 Nm. A third-party torque guide claims 130 Nm and M14 threads; the handbook torque and M12x1.5 parts/fitment listings take precedence here.
Trim names and wheel packages vary by market and year; the stock rows describe common RT packages, not every low-ride or special edition.
CalOffroad lists lower-offset 17x8.5 ET5 wheels with a possible flare requirement. That is not evidence for a universal safe offset range.
Check full steering lock and suspension travel with the car loaded. Match wheel load rating, tyre load and speed ratings, fastener seats and brake clearance.
