33 vs 35-inch tyres on a LandCruiser 79 Series dual cab

For a 79 Series dual cab built around touring, work and everyday use, we would investigate a 33-inch-class setup before committing to 35s. If you specifically want 35s, price the complete conversion first. Buying tyres and finding a way to make them fit afterwards is an expensive order of operations.

This is a decision guide for Australian 79 Series double-cab chassis vehicles. It includes V8 and 2.8-litre versions as separate fitment enquiries. It does not transfer single-cab, 76 wagon or 78 Troop Carrier fitment to your ute.

What changes between 33s and 35s?

A true 35-inch tyre is 50.8 mm taller than a true 33. On a live axle, that gives a theoretical 25.4 mm increase beneath the axle, before tyre deflection. The body looks substantially taller, but you have not gained two inches beneath the differential.

Metric sizes muddy the comparison:

These are calculations from size notation, not measured product dimensions or approved 79 fitments. Check the tyre manufacturer's diameter and wheel-width range before comparing quotes.

Why the dual cab deserves its own answer

Start with your build date, engine, transmission, axle configuration and approval paperwork. Toyota's 2024 range announcement documents the addition of the four-cylinder automatic. A supplier's V8 demonstration is not enough to approve a different vehicle.

Then describe the rear build. An empty tray, a permanent canopy and a touring load are different purchase briefs. We would assess the finished vehicle with its usual equipment and proposed spare-wheel location, rather than judge clearance from an empty-ute photograph.

Can you fit 35s?

There are documented conversion products for particular dual cabs. Superior Engineering's Outback listings include SUP-79GEN3-FEDMIDL-KIT for 2022-on VSC dual cabs, specifying 315/70R17 within a larger conversion.

That establishes a specific pathway to investigate. It does not establish that a stock 79 accepts 35s, or that every tyre sold as a 35 is covered. Ask the supplier for the current fitment schedule and approval documents for your VIN, especially if the vehicle is already registered.

Which would we choose?

Daily driver with occasional trips: decide whether you actually need a diameter increase. A suitable all-terrain in an approved existing size may answer the brief.

Touring dual cab with a canopy: start the quote around a suitable 33-inch-class option. Ask what you gain against the existing tyres and what the complete wheel, spare and clearance solution costs.

Dedicated larger-tyre build: consider 35s when the required terrain and desired look justify the full conversion. Include gearing, braking, steering and certification in the discussion, not just suspension height.

Those are our planning preferences, not measured fuel-economy or durability rankings.

The quote should describe the whole vehicle

Require the exact tyre, wheel width and offset, any body changes, loaded clearance checks and the spare arrangement. Ask which work is mandatory and which is optional styling. A larger load index does not itself increase the vehicle's permitted carrying capacity.

Confirm registration requirements with the relevant authority using VSB 14 as the national starting point. An advertisement saying 'Australia-wide legal' still needs a matching approval path for your vehicle.

Decide on the appearance before ordering

Compare the tyre-to-wheel proportions against your actual tray or canopy. A tall tyre on a restrained wheel can look very different from a wide tyre pushed towards the guards.
