What Size Tyres Fit with a 2-Inch Lift Kit? The 2026 4x4 Fitment Guide

A 2-inch lift is the most popular modification for Australian 4x4s, but it isn't a magic fix for clearing oversized rubber. Many drivers assume that simply adding height solves every clearance issue, only to find their new Maxxis tyres scrubbing the guards during the first weekend trip. If you're trying to figure out what size tyres fit with a 2 inch lift kit, you've likely encountered a mess of conflicting forum advice and workshop myths that ignore the technical reality of wheel offset and suspension travel.

We understand the frustration of building a rig that looks the part but fails on the tracks. This guide provides a definitive 2026 fitment breakdown to help you avoid the dreaded scrub and stay compliant with VSB14 regulations in Western Australia. You'll learn how to balance tyre diameter with rim offset, when a body mount chop becomes a necessity, and how to set up your Dobinsons or Fulcrum suspension for maximum performance. We'll move past the guesswork and look at the functional expertise required to get your fitment right for Perth conditions the first time.

The 2-Inch Lift Baseline: What Changes Under Your 4x4?

A 50mm lift is the standard benchmark for Australian 4WD builds. It provides a significant increase in ground clearance without compromising the vehicle's centre of gravity or daily drivability. While many owners install these kits to fit larger rubber, it's vital to understand that a suspension lift primarily raises the chassis and body away from the axles. It doesn't actually change the physical dimensions of your wheel arches. This distinction is critical when determining what size tyres fit with a 2 inch lift kit on your specific rig.

There's a common misconception that height alone dictates clearance. A suspension lift uses taller springs and tuned shock absorbers to push the chassis up, whereas a body lift uses spacers between the chassis and the body shell. In Western Australia, a 50mm suspension lift is often the legal limit under VSB14 regulations before you require complex engineering certification. We focus on suspension upgrades from brands like Dobinsons and Fulcrum because they improve mechanical performance rather than just providing a cosmetic height increase.

Why a 2-Inch Lift is the Australian Standard

Most touring rigs in Perth carry substantial weight. Between steel bull bars, winches, and rear drawers, factory springs often sag under the pressure. Upgrading your 4x4 suspension with heavy-duty components restores lost ride height and improves stability on corrugated tracks. This 2-inch baseline balances off-road capability with on-road safety. It allows for better articulation in ruts while ensuring the vehicle remains predictable at highway speeds. Using reliable components from Dobinsons or Fulcrum ensures your suspension can handle the heat and dust of outback conditions without failing when you're far from home.

The Relationship Between Lift Height and Tyre Diameter

When asking what size tyres fit with a 2 inch lift kit, you must account for the full range of suspension movement. A lift kit improves your approach, departure, and ramp-over angles by raising the body. However, as the suspension compresses during articulation, the tyre still follows the same factory arc into the wheel arch. If you choose a tyre that is too large, it will scrub against the guards or the body mount when the suspension hits full bump. This is particularly common at full steering lock. A 2-inch lift gives the tyre more breathing room at rest, but it doesn't solve clearance issues that occur when the suspension is fully compressed or the wheels are turned.

Tyre Size Comparison: 31s vs 32s vs 33s on a 2-Inch Lift

Choosing the right rubber involves more than just picking a number off a sidewall. When determining what size tyres fit with a 2 inch lift kit, you're usually choosing between imperial measurements like 31, 32, or 33 inches, or their metric counterparts like 265/70R17 or 285/70R17. Most modern dual-cab utes follow a 'factory plus one' rule of thumb. If your vehicle came with 30-inch tyres, moving up to a 31 or 32-inch set is generally the most efficient upgrade path. This maintains a balance between improved ground clearance and mechanical reliability.

You must also consider the tread design. Aggressive options like Maxxis Razr mud-terrains feature prominent shoulder lugs and side biters. While these provide excellent grip on soft Perth sand or muddy ruts, they increase the effective width of the tyre. This extra bulk can lead to scrubbing on inner guard liners where a standard highway tyre of the same size might clear. There's also a clear trade-off with fuel economy. Larger, heavier tyres increase rolling resistance and unsprung weight, which often results in higher fuel consumption and a slight drop in low-end acceleration.

31 To 32-Inch Tyres: The Safe Bet

These sizes are the practical choice for most Australian touring setups. A 265/70R17 (roughly 32 inches) usually fits without any guard modifications or trimming. They provide enough extra height to clear most obstacles on standard Western Australian tracks while maintaining factory-like throttle response. This setup is ideal for drivers who prioritise reliability and want to avoid the hassle of recalibrating complex electronic stability systems. It's a "fit and forget" solution that works well with both Dobinsons and Fulcrum suspension kits.

33-Inch Tyres: The 2-Inch Lift Challenge

Moving to a 33-inch tyre, such as a 285/70R17, is the most popular goal for Ranger and HiLux owners. While they provide a rugged stance, they present significant fitment challenges. On a 2-inch lift, these tyres almost always scrub the front mudflaps or the inner plastic liners at full steering lock. You'll likely need to trim the bumper plastics or use a heat gun to reshape the liners for clearance. It's also vital to check the Legality in Western Australia, as increasing your total tyre diameter by more than 50mm can void your insurance without proper certification. To ensure you get the right tread for your specific offset, you can view our range of Maxxis tyres to find a technical match for your rig.

Beyond the Lift: Wheel Offset and the Body Mount Chop

A suspension lift provides the vertical clearance, but wheel offset dictates the horizontal path your tyre follows when you turn the steering wheel. Offset is the distance from the hub mounting surface to the centre line of the wheel. It's the most overlooked factor when drivers ask what size tyres fit with a 2 inch lift kit. If you get the offset wrong, even a relatively small tyre can cause significant damage to your guards. Choosing the right wheels is just as important as the lift itself for achieving a scrub-free setup.

Understanding Wheel Offset (+30 vs +0 vs -12)

Positive offset (like +30) keeps the wheel tucked inside the guard, which is common for factory setups. A zero (+0) or negative offset (like -12) pushes the wheel further out towards the flare. While this wide stance looks aggressive and improves stability, it increases the scrub radius. This means the tyre swings in a much larger arc when you turn the wheel. According to this Tyre Clearance and Fitment Guide, a wider stance often forces the tyre into the rear of the front wheel arch. You might find that a 33-inch tyre on a -12 offset scrubs significantly worse than a 35-inch tyre on a +20 offset because of this swing arc.

When Do You Need a 4x4 Body Mount Chop in Perth?

Modern Independent Front Suspension (IFS) vehicles, including the Toyota HiLux, Prado, and the 200 or 300 Series LandCruiser, have a steel body mount located directly behind the front tyre. When you fit larger Maxxis tyres on a 2-inch lift, this mount is the first thing the rubber hits at full steering lock. A body mount chop is the standard professional solution. This involves technical fabrication where we cut back the protruding steel mount to create clearance, then weld a new steel plate over the opening to maintain structural integrity.

We finish the plate with a clean coat of paint to ensure a factory look and prevent corrosion. This is a workshop-only job that requires precision welding and an understanding of vehicle geometry. Attempting to fit 33-inch tyres on a 2-inch lift without addressing this interference often leads to torn tyre lugs and structural rubbing. At our Perth workshop, we assess your specific vehicle and wheel combination to determine if a chop is necessary before you commit to your new tyre set. This ensures your rig remains functional on the hardest tracks without compromising safety.

Committing to a new set of Maxxis tyres is a significant investment that often exceeds $2,000. Before you commit, you need a systematic way to determine what size tyres fit with a 2 inch lift kit on your specific vehicle. Every rig is slightly different due to accessory weight, manufacturing tolerances, and the specific brand of suspension installed. Testing for clearance at 'full bump' is the only way to guarantee your tyres won't rip off a flare when you're crossing a deep washout. This is the point of maximum suspension compression where the axle hits the bump stops.

If you don't have the tyres yet, you can create a simple measurement tool using a piece of heavy wire or a cardboard template cut to the radius of your desired tyre. Rotate this template through the wheel arch while the vehicle is at its intended ride height. However, the most reliable method is using a 'dummy tyre'—borrowing a spare wheel from a mate with the same size and offset you plan to run. This allows you to check clearance at both full left and full right steering lock under real-world conditions.

The Full Lock and Flex Test

Step 1: Park your vehicle on a flat, level concrete surface. Cycle the steering from lock to lock and observe the tyre's proximity to the guards and chassis. Step 2: Measure the distance between the tyre tread and the closest points of the bull bar or body mount. You should maintain at least 15mm of clearance to account for tyre bag and chassis flex. Step 3: Use a flex ramp or a high kerb to compress one front wheel while the other is extended. Repeat the steering cycle. If the tyre touches any component during this flex test, it will definitely scrub when you're off-road.

Identifying Scrub Points

If you suspect your current setup is too tight, look for 'shiny' spots on the vehicle. Rubbing rubber quickly polishes the paint off the chassis rail or wears through plastic inner liners. A common failure point on modern IFS utes is the Upper Control Arm (UCA). If the tyre sidewall sits too close to the UCA, you risk a catastrophic tyre failure if the suspension flexes and the arm bites into the rubber. Accessories like Supreme Innovations bull bars are engineered with high-clearance wings to assist with fitment, but you must still verify that the tyre doesn't contact the inner bar work during hard braking or cornering. If your measurements show a tight fit, you can browse our 4x4 accessories and wheel upgrades to find components that provide the necessary clearance for your build.

Professional Fitment and Legality in Western Australia

Achieving the perfect stance involves more than just mechanical clearance; it requires strict adherence to Western Australian road laws. While enthusiasts often focus on the physical question of what size tyres fit with a 2 inch lift kit, the legal reality in WA is governed by the National Code of Practice, specifically VSB14. Understanding these limits is essential for keeping your vehicle roadworthy and ensuring your insurance remains valid. A rig that looks great but fails a roadside inspection or an insurance claim is a liability you don't want to carry.

Staying Legal on WA Roads

The current regulations in Western Australia state that a combined vehicle lift, which includes the suspension, tyres, and any body lift, cannot exceed 50mm without engineering certification. This is a critical point that many owners overlook. If you install a 50mm (2-inch) Dobinsons suspension kit and then add Maxxis tyres that are 50mm larger in diameter than the factory originals, you have added another 25mm of lift. This brings your total lift to 75mm, which technically requires an approved engineer's report to be legal on Perth roads.

Beyond the height, you must also consider tyre poke. Your tyres must stay within the track width limits and remain covered by the vehicle's guards or flares. If your chosen wheel offset pushes your 33-inch rubber outside the bodywork, you will need to install aftermarket flares to stay compliant. Professional fitment at a specialist workshop ensures these measurements are calculated correctly before the parts are fitted. We also address speedometer accuracy. Larger tyres change your final drive ratio, often making your speedometer read slower than your actual speed, which can lead to unwanted fines.

Frequently Asked Questions

Can I fit 35-inch tyres with just a 2-inch lift?

No, you cannot fit 35-inch tyres safely with only a 2-inch lift. This size usually requires at least a 3 or 4-inch lift and significant guard modifications to avoid catastrophic scrubbing. When researching what size tyres fit with a 2 inch lift kit, it's important to remember that 35s will foul the chassis and body mounts even during light off-road use. We don't recommend this setup for touring rigs.

Will 33-inch tyres rub on a stock HiLux with a 2-inch lift?

Yes, 33-inch tyres (285/70R17) will almost certainly rub on a HiLux with a 2-inch lift. The interference typically happens at the front mudflaps and the body mount located behind the front wheel. To clear these properly at full steering lock, you'll need to trim the bumper plastics and perform a body mount chop. This is a common requirement for anyone wanting the aggressive look of 33s on a modern IFS HiLux.

Is a body mount chop legal in Western Australia?

Body mount chops are legal in Western Australia if the work is completed to a professional standard that maintains structural integrity. The mount must be plated with steel of equivalent thickness and welded by a specialist to comply with VSB14 regulations. It's a functional modification used to clear larger rubber safely. We recommend having this done at a workshop to ensure the vehicle remains roadworthy and safe for your next outback trip.

How much does a 4x4 body mount chop cost in Perth?

The price for a body mount chop in Perth depends on the vehicle's design and the specific labour required for the fabrication. Because this process involves precision cutting, steel plating, and welding, it's a technical job that varies between different 4x4 models. We suggest visiting our workshop for a custom fitment consultation. Our team can assess your current setup and provide a detailed quote based on your specific vehicle and tyre combination.

Do I need to change my wheels to fit 285/70R17 tyres?

You'll likely need to upgrade your wheels to fit 285/70R17 tyres safely. Factory wheels often have a high positive offset that pulls the tyre inwards, causing the sidewall to rub against the Upper Control Arm (UCA) or chassis. Moving to a wheel with a lower offset, such as +20 or +12, pushes the tyre out and provides the necessary clearance. This ensures your Maxxis tyres have enough room to breathe during suspension articulation.

What is the best wheel offset for a 2-inch lift on a Ranger?

A +35 to +25 offset is typically the best choice for a 2-inch lifted Ranger. This range provides a balanced stance that clears internal suspension components without forcing the tyre too far past the flares. When deciding what size tyres fit with a 2 inch lift kit, getting the offset right is just as important as the lift. It prevents the tyre from swinging into the rear of the guards during full steering lock.

Will larger tyres void my vehicle's warranty?

Larger tyres won't void your entire warranty, but they can impact claims on specific drivetrain parts. Manufacturers may refuse to cover failures in CV joints, wheel bearings, or differentials if they believe the increased weight of the tyres caused the issue. It's a good idea to check with your dealer before modifying a new vehicle. Most owners find that the improved off-road performance outweighs the potential risks to these specific wear-and-tear components.

Do I need to re-gear my diffs after fitting 33s?

Re-gearing isn't strictly necessary for most modern diesel 4x4s running 33-inch tyres. Most engines have enough torque to handle the slight change in final drive ratio, though you might notice the transmission hunting for gears on hills. If you're towing a heavy caravan or driving a petrol vehicle, re-gearing can help restore lost acceleration and fuel economy. For general touring around Perth, the factory gearing is usually sufficient for a 33-inch setup.
