Mitsubishi Triton MQ Wheel Fitment Guide: Bolt Pattern, Sizes & Offset Explained

If you're chasing a fresh set of wheels for your Mitsubishi Triton MQ, getting the fitment right matters just as much as picking a style you like. The wrong Triton MQ wheel fitment combination can mean rubbing on the guards, uneven wear, poor handling, and even a failed roadworthy inspection. This guide walks through the bolt pattern, wheel diameters, and offset ranges that work for the 2015–2018 Triton MQ, plus where offset can and can't be pushed.

Triton MQ Bolt Pattern and PCD

The Mitsubishi Triton MQ (2015–2018) runs a 6-stud, 139.7mm PCD (bolt circle) pattern, shared with most other 6-stud Japanese and Thai-built utes. This is the number one thing to confirm before buying any aftermarket wheels — a wheel with the wrong PCD simply won't bolt up, no matter how good the size and offset look on paper.

Wheel Diameters: 16, 17 & 18 Inch Options

The Triton MQ has plenty of headroom in the wheel arch, which is why it's popular for 16", 17" and 18" wheel upgrades. All three sizes are available across our range in a mix of alloy and steel construction:

• 16 inch — great for touring and remote-area work, taller sidewall tyre options, easier to source in all-terrain and mud-terrain tread patterns
• 17 inch — the most common upgrade size, balancing looks with tyre choice
• 18 inch — a more aggressive stance, popular for street-focused builds, generally means a lower-profile tyre

The ROH Vapour is a solid 16" option, available in 6/139.7 fitment with a range of offsets to suit both standard and flared guards.

Offset: What's Ideal, What's Safe, and What's Too Aggressive

Offset is where most fitment issues actually happen, and it's worth understanding before you order. For a Triton MQ running standard guards, an offset around +18 is considered the ideal starting point — it keeps the wheel tucked in nicely without excessive poke and avoids rubbing on the coil struts or inner guard liners.

Offset can be pushed wider or tucked in further depending on other modifications:

• +12 to +38 — the general safe working range for a Triton MQ, with the actual number depending on wheel width, tyre size, and whether guard flares are fitted
• Fitted with flares — flares give extra coverage over the tyre, which allows for a lower (more aggressive) offset without the tyre sitting outside the bodywork
• +10 or lower — this is considered an aggressive offset and may push the tyre outside the guard line. Depending on your state's vehicle standards, this can mean the vehicle fails to comply with ADR width and coverage rules, so it's worth checking your local requirements or getting a professional opinion before going this low

As a rule of thumb: the wider and more negative (lower) the offset, the more poke you'll get — and the more likely you'll need flares or a widetrack kit to stay road-legal and rubbing-free.

Recommended Wheels for the Triton MQ

Here are a few options from our range that suit the MQ's 6/139.7 pattern across different sizes and offsets:

The Fuel Rebel 6 in 17x9 is available in 6/139.7 with offsets from -12 through to +1, giving a noticeably wider stance for those running flares. It's one of our best sellers for MQ owners after a bolder look.

Stepping up to 18", the Fuel Vector D579 is available in 6/139.7 with offsets around +19 to +20 — closer to the ideal +18 mark, and a good match if you're keeping factory guards or only running minimal flares.

For those wanting a more conservative, factory-plus look, the ROH Assault range also comes in 6/139.7 fitments and is a popular choice for Triton owners wanting a stronger wheel without an extreme offset.

Where to Start

If you're planning a full wheel upgrade for your Triton MQ, we'd suggest working through it in this order:

1. Confirm whether you're keeping factory guards or fitting flares — this determines your safe offset range
2. Pick your wheel diameter based on intended use (16" for touring, 17–18" for a street-focused build)
3. Choose an offset within the +12 to +38 range, sitting as close to +18 as your guard setup allows
4. Check tyre size compatibility with your chosen wheel width to avoid rubbing on struts or guard liners
5. Get a professional fitment check before heading off, especially if you're running a lower offset
