The Mitsubishi Triton is a mainstay of the Australian dual-cab ute market, and the sixth-generation model (the MV, launched here in early 2024) is sold as the GLX, GLX+, GLS and GSR, plus cab-chassis and single-cab configurations for fleet and tradie buyers. As with any ute, the “right” tyre size depends on which body and grade you have — and, crucially, on keeping the load rating your vehicle was built around. This guide sets out the Australian fitments, the wheel specs that matter, and how to choose rubber that can actually carry and tow what a Triton is rated for.

Treat every figure here as a 2026 guide. Mitsubishi varies wheel packages across grades and model years, so confirm against the tyre placard on your door jamb, your current sidewall markings and your owner’s handbook before buying.

What tyre sizes does the Mitsubishi Triton use in Australia?

Wheel diameter steps up with grade. Workhorse grades sit on 17-inch wheels with a taller, tougher tyre; the sportier GLS and GSR move to 18s; and cab-chassis and single-cab models run 16-inch steel with commercial-rated rubber.

Sizes vary by grade, body and model year. The 265/65R17 and 265/60R18 fitments are the usual dual-cab sizes; the 16-inch commercial sizes appear on cab-chassis and single-cab models. Always confirm against your placard.

The 265/65R17 and 265/60R18 are designed to a near-identical rolling diameter, so the speedo reads correctly either way. Many GLX utes leave the factory on an all-terrain tyre, which is why the ride and noise differ from a road-biased GLS — the trade-offs are covered in all-terrain vs highway-terrain vs mud-terrain. For the numbers themselves, see how to read a sidewall.

What are the Mitsubishi Triton wheel specs (PCD, bore, offset)?

Like most 4WD utes, the Triton uses a six-stud wheel. The pattern is shared across the segment, but — and this is where owners come unstuck — a shared stud pattern does not mean wheels swap freely between brands.

That 6×139.7 pattern is the same as the Ford Ranger, Toyota HiLux and Isuzu D-Max — but the centre bore and offset differ between them, so a wheel that bolts on may still sit off-centre or foul the suspension. Our guides to bolt pattern and PCD and wheel offset and backspacing explain how to check both. One important warning: the Triton shares its badge with the Mitsubishi Outlander, but not its platform or stud pattern — the Outlander is a five-stud monocoque SUV, so the two do not share wheels.

What tyre pressures should a Mitsubishi Triton run?

Set cold pressures to the placard on your door jamb. As a guide, an unladen dual-cab Triton sits around 2.2 bar (about 32 psi) front and rear, but — unlike a car — a ute’s rear pressure should climb significantly when you load the tray or hitch a trailer. Your placard (and the handbook’s laden figures) are the authority here, not a single number from a forum.

Because the rear axle carries most of the payload, running the back tyres at unladen pressure under a full load causes heat build-up and centre-of-edge wear. When you’re towing, step pressures up per the handbook — our complete guide to tyre pressures for towing a caravan walks through it, and placard vs sidewall maximum explains why you never just inflate to the number on the tyre. Off the bitumen, dropping pressure is a different discipline again — see sand pressures and corrugated dirt roads.

Does the Mitsubishi Triton have a full-size spare?

Yes. Like most dual-cab utes, the Triton carries a full-size spare slung under the rear of the tray, and the GLX includes a full-size steel spare as standard. This is a genuine advantage over the space-savers and repair kits fitted to many SUVs — a full-size spare lets you keep driving at normal speed and tackle remote travel with confidence.

Two things to watch: an underslung spare should be checked for pressure and corrosion periodically (it’s easy to forget — see spare tyre pressure), and if you fit aftermarket all-terrains, decide whether your spare should match — covered in do you need a matching spare. For remote trips, many owners carry a second spare; our guide on carrying a second spare legally covers the rules. The Triton is also on our list of new cars that still come with a full-size spare.

How much do Mitsubishi Triton tyres cost in Australia?

Ute tyres cost more than passenger rubber because they’re built tougher and carry more load, and all-terrains cost more again than highway tyres. As a 2026 guide only — always get a live quote for your size:

Indicative 2026 ranges including fitting, balancing and disposal; prices move with brand, store and supply. A set of five (matching the spare) is dearer again.

Because a Triton often needs five matching tyres (including the full-size spare) and all-terrains wear faster than highway tyres, the real figure to compare is cost per kilometre, not sticker price. See how the chains stack up in our reviews of Bob Jane T-Marts and Tyrepower, and why 4WD tyres cost more.

What are the best replacement tyres for a Triton?

Match the tyre to how the ute actually spends its week — not to how it looks on the weekend:

• Mostly bitumen, occasional dirt (80/20): a quality all-terrain is the sweet spot. See best tyres for 80% road, 20% dirt.
• Towing and heavy loads: prioritise load rating and construction. See best towing tyres for a dual-cab ute.
• Work ute carrying a full tray daily: see best tyres for a tradie’s work ute and consider LT-construction tyres.
• High-kilometre highway life: see best long-lasting tyres for a dual-cab ute.

Australia’s legal minimum tread is 1.5 mm (not the 1.6 mm quoted overseas), but a loaded ute loses wet grip well before that — replace nearer 3 mm. And whatever you fit, don’t drop below the placard load index, which brings us to the single most important point for a ute.

Load rating, towing and GVM: what you must not drop below

A Triton is rated to carry a tray-load and tow a braked trailer, and that rating assumes tyres with enough load capacity. Fitting a lower load index than the placard — easy to do if you chase a cheaper passenger-construction tyre — can be unsafe and leave you non-compliant. For heavy towing or after a GVM upgrade, LT-construction tyres with the right load rating are often the honest answer.

This is general information, not advice for your specific setup: the legal rules around load ratings, GVM and GCM are set out in tyre rules for towing, and the plus-sizing traps unique to utes are covered in plus-sizing a dual-cab ute. If you’re changing wheel or tyre size, confirm the fitment and load rating with a licensed fitter and check your state’s engineering rules.

Frequently asked questions

What size tyres does a Mitsubishi Triton take?

Current dual-cab grades run 265/65R17 (GLX and GLX+) or 265/60R18 (GLS and GSR). Cab-chassis and single-cab models use 245/70R16 or 205R16C commercial rubber. Confirm your exact size on the placard.

What is the bolt pattern on a Mitsubishi Triton?

The Triton uses a 6×139.7 mm six-stud pattern with M12×1.5 studs. It’s shared with the Ranger, HiLux and D-Max, but the centre bore and offset differ, so wheels aren’t automatically interchangeable.

Does the Mitsubishi Triton have a full-size spare?

Yes — the Triton carries a full-size spare slung under the tray, including a full-size steel spare on the GLX. That’s a real plus for remote travel compared with the space-savers fitted to many SUVs.

What tyre pressure should I run in a Triton when towing?

Follow your placard and handbook. Unladen, a dual-cab sits around 2.2 bar (~32 psi); rear pressure should rise significantly when loaded or towing. The placard’s laden figures are the authority — never just inflate to the sidewall maximum.

Can I fit all-terrain tyres to my Triton?

Yes, and an all-terrain suits the 80/20 road/dirt use many Tritons see. Keep at least the placard load index (consider LT-construction for heavy work), match the spare if you can, and expect more noise and slightly higher fuel use than a highway tyre.
