A two-inch suspension lift is the most popular first mod on Australian touring 4WDs, and the first question that follows is always the same: what tyres can I now fit? The honest answer is that a lift unlocks bigger rubber but doesn’t guarantee it — exactly what fits depends on your wheel offset, tyre width, guard shape and how much the suspension flexes. This guide covers the practical choices for a lifted ute or wagon in 2026.
What tyre size can a two-inch lift actually fit?
As a guide, a two-inch (roughly 50 mm) lift gives enough clearance for about one size step over standard — frequently up to a 33-inch (about 285/70R17 or 285/75R16) tyre on common dual-cab utes and wagons. That extra clearance matters most at full articulation off-road, where a taller tyre would otherwise rub the inner guard liner. On a 79 Series LandCruiser, for example, a 33×12.5R16 is generally considered to need a two-inch lift to clear the guards under flex, while 35s want a two-inch minimum and three inches for serious work.
Whether a given size clears on your vehicle is model-specific, so confirm with your suspension specialist or tyre fitter before buying. Wider tyres (the 12.5-inch-wide sizes) usually also need guard flares to legally cover the tread at full lock and articulation. Keeping the new tyre’s rolling diameter close to standard keeps the fitment legal and your gearing sensible.
Should you run all-terrain or mud-terrain after a lift?
For most lifted touring 4WDs that spend the bulk of their life on bitumen and gravel, an all-terrain (A/T) is the sweet spot: quiet enough to live with, tough enough for corrugations and sharp rock, and usually carrying the 3PMSF snow marking. A mud-terrain (M/T) only earns its place if you genuinely spend time in deep mud or rutted tracks — the trade-off is more road noise, shorter tread life and weaker wet grip. The full breakdown is in our all-terrain vs highway-terrain vs mud-terrain comparison.
Do you need LT-construction tyres on a lifted 4WD?
If you tour loaded, tow, or run corrugated and rocky tracks, an LT (Light Truck) construction tyre is worth the extra weight and fuel: tougher plies and a higher load rating resist staking and sidewall damage. If your lifted ute is mostly a road car, a passenger-construction A/T may ride better and use less fuel. Our guide on whether you need LT-construction tyres walks through the honest trade-off.
Load rating: the trap that catches lifted utes
A lift changes ride height, not your vehicle’s weight limits. The tyre you fit must still carry the load on each axle — the sum of the load indices per axle needs to meet or exceed the axle rating. Upsizing to a wider or taller tyre sometimes drops the available load index, which is exactly the wrong direction for a loaded tourer. If you’ve also done a GVM upgrade, the load-rating maths becomes non-negotiable, and a licensed certifier is the right person to sign it off.
Stock vs upsized: what changes
| Setup | Approx. diameter | Lift needed | Speedo effect |
|---|---|---|---|
| Stock (e.g. 265/70R16) | ~31.6 in | None | Accurate |
| +1 size (e.g. 285/75R16) | ~32.8 in | Benefits from 2 in | Reads ~4% high |
| 33-inch (e.g. 33×12.5R16) | ~33 in | 2 in typically required | Reads ~3% high |
| 35-inch | ~35 in | 2 in min / 3 in better | ~10% — recalibrate |

What bigger tyres do to your speedo, fuel use and gearing
A taller tyre makes your speedometer under-read — it shows slower than you’re actually going — which can push you over the limit unknowingly. It also effectively raises your gearing, which hurts acceleration, towing and economy. Expect a measurable jump in fuel use; our breakdown of the fuel-economy cost of going to 33-inch tyres puts numbers on it, and some builds end up needing a diff re-gear. Before you drive far, read whether you need to recalibrate your speedo after upsizing.
Clearance, rubbing and the jobs that come with the fit
Budget for the extras: guard flares for wide tyres, possibly wheel spacers depending on offset, and a wheel alignment after the suspension lift — ride height changes your camber and toe. It’s also worth knowing whether the change needs engineering sign-off in your state; see whether bigger tyres affect your warranty and keep records of reputable fitment. According to 4X4 Australia, a two-inch lift isn’t automatically exempt from compliance requirements, so check your state or territory rules. Model-specific fitment data, like the 70 Series tyre-size guide, shows just how much the answer depends on the exact vehicle.
Frequently asked questions
Can I fit 33s with just a two-inch lift? Often yes on common utes and wagons, but it depends on your guards, offset and flares — confirm with your fitter.
Do I need a different wheel too? Sometimes. Wider 12.5-inch tyres may need a specific offset or spacers, and that can affect legality.
Will a lift and 33s fail a roadworthy? Not if done to your state’s rules with correct flares, load rating and (where required) certification. Illegal tyre coverage or excessive diameter can fail.
Is an all-terrain enough for a touring 4WD? For 80% road / 20% dirt touring, yes — an LT-construction A/T is the common choice.
Bottom line: A two-inch lift typically opens the door to a 33-inch all-terrain, ideally in LT construction with the correct load rating. Keep rolling diameter near standard, fit flares where needed, and factor in an alignment, a speedo check and extra fuel. Confirm the exact size with your tyre fitter and your state’s rules before you buy.
