For years, aftermarket wheel upgrades were largely about increasing diameter.

Factory 18-inch wheels became 19s. Then 20s became increasingly common on Australian performance and street cars.

But another change has become just as important:

Drivers are paying more attention to wheel width—not just wheel diameter.

Across modified street cars, performance builds and Holden Commodore and HSV applications, wider aftermarket wheels are increasingly being considered as part of a complete wheel-and-tyre setup.

There are practical reasons for this. A wider wheel can support a wider tyre, change the overall tyre footprint and provide more flexibility when building a performance-oriented setup.

But there is an important distinction:

For Australian street cars, the goal should not simply be fitting the widest wheel possible. The goal is finding a wheel width that works as part of the entire vehicle setup.

1. Why Are Wider Wheels Becoming More Common?

Factory wheels are designed around a large number of competing requirements.

Manufacturers need to balance:

• Ride comfort
• Tyre availability
• Fuel efficiency
• Manufacturing cost
• Steering characteristics
• Noise and vibration
• Clearance across different vehicle configurations
• Long-term everyday usability

That means a factory wheel width is not necessarily the maximum width that a particular vehicle platform can accommodate.

Aftermarket builds have different priorities.

A modified street car owner may be looking for:

• A wider tyre footprint
• A more performance-focused setup
• Improved wheel-to-tyre proportions
• A more planted visual stance
• A staggered front/rear configuration
• Better compatibility with the intended suspension and tyre combination

This is one reason wider wheels have become an important part of the Australian aftermarket.

Instead of asking only:

“How many inches can I increase the diameter?”

more enthusiasts are asking:

“What wheel width and tyre combination actually suits my build?”

2. Wider Wheels Are Not Simply About Appearance

It is easy to associate wider wheels with a more aggressive stance.

However, wheel width has a direct relationship with tyre selection and the overall behaviour of the wheel-and-tyre package.

A wider wheel can allow the use of a wider tyre when the vehicle, suspension and available clearance are suitable for that combination.

This can be relevant to performance-oriented builds where the owner wants a larger tyre contact footprint.

But wheel width by itself does not create better performance.

The final result depends on the complete combination of:

Wheel Width + Tyre Width + Tyre Profile + Offset + Suspension + Vehicle Clearance

Changing one of these variables can affect the others.

3. Why Wider Doesn't Automatically Mean Better

One of the most common mistakes when choosing aftermarket wheels is assuming:

“If wider is good, even wider must be better.”

In reality, excessive wheel width can create additional fitment and driving considerations.

Guard Clearance

A wider wheel and tyre combination occupies more space inside the wheel arch.

If the offset is not correctly selected, the wheel may sit too far outward and reduce guard clearance.

This can become particularly important on lowered vehicles where suspension compression changes the relationship between the tyre and guard.

Suspension Clearance

Moving a wider wheel inward can create additional clearance concerns around:

• Struts
• Control arms
• Suspension components
• Inner wheel arch areas

This is why wheel width should never be considered separately from offset.

For a more detailed explanation, see our Wheel Offset Explained guide.

Steering Clearance

Front wheels need to clear the vehicle's steering and suspension components throughout the steering range.

A setup that looks fine when the wheels are pointing straight ahead may have less clearance at full steering lock.

Tyre Sidewall

The relationship between tyre width and wheel width also affects the shape of the tyre sidewall.

Using a tyre that is too narrow for a very wide wheel can create an unnecessarily stretched sidewall, while selecting a wider tyre without checking available vehicle clearance can introduce rubbing issues.

The objective should be a properly matched wheel-and-tyre package rather than simply maximising wheel width.

Ride Quality

Wider wheels are often paired with lower-profile tyres, particularly on 20-inch performance setups.

However, a larger wheel and shorter tyre sidewall can change the way the vehicle responds to bumps, potholes and rough road surfaces.

This is especially relevant to Australian street cars that may regularly encounter imperfect roads, expansion joints and long-distance highway driving.

4. Why Commodore and HSV Owners Are Interested in Wider Setups

Holden Commodore and HSV vehicles have a particularly strong aftermarket wheel culture in Australia.

Models such as the:

• VE Commodore
• VF Commodore
• SSV Redline
• HSV GTS
• HSV GTSR
• Gen-F performance models

are frequently used as the foundation for modified street and performance builds.

These vehicles also lend themselves well to different wheel-and-tyre configurations, including staggered setups.

A common example for performance-oriented builds is:

20x8.5 front + 20x9.5 rear

This type of staggered arrangement can provide a different front/rear wheel and tyre package while maintaining a factory-inspired performance-car appearance.

However, the exact wheel width, offset and tyre size still need to be checked against the specific vehicle.

5. Why Staggered Wheel Setups Remain Popular

One of the most recognisable applications of wider rear wheels is the staggered setup.

A staggered setup uses different wheel and/or tyre widths at the front and rear.

For example:

The reason this configuration is common on performance-oriented vehicles is that the front and rear axles do not necessarily have identical packaging requirements.

A wider rear wheel can accommodate a wider rear tyre where the vehicle and drivetrain setup are suited to it.

But staggered does not automatically mean better.

It can also affect tyre rotation options and requires the front and rear tyre sizes to be selected as a compatible package.

For Holden owners considering this type of configuration, our Holden VE/VF Staggered Wheel Fitment Guide provides more detail on the factors that need to be checked.

6. Wheel Width and Tyre Width Must Be Considered Together

This is arguably the most important concept in choosing wider wheels.

A wider wheel is only useful when it is correctly matched to the tyre.

Wheel width and tyre width work as a pair.

When choosing a combination, consider:

• Recommended tyre width range
• Tyre profile
• Wheel diameter
• Available guard clearance
• Suspension clearance
• Steering clearance
• Overall tyre diameter

For example, changing from a narrower wheel to a wider wheel does not automatically mean that the tyre should simply become as wide as possible.

The tyre needs to be appropriate for the wheel and vehicle application.

Likewise, the same tyre width can behave differently depending on the wheel width and tyre model.

7. What Happens When You Go Too Wide?

Going wider without considering the rest of the setup can introduce several problems.

Too Far Outward

If the combination sits too far outward, the tyre may move closer to the guard edge and increase the risk of rubbing.

Too Far Inward

If the wheel is positioned too far inward, clearance around suspension components can become the limiting factor.

Too Much Tyre

A wider tyre can increase the overall footprint, but it also occupies more physical space.

On a lowered vehicle, this can become especially important during suspension compression and steering.

Incorrect Tyre-to-Wheel Relationship

A very wide wheel paired with an unsuitable tyre width can create an undesirable sidewall profile and compromise the intended balance of the setup.

The solution is not simply to choose a narrower tyre or a wider wheel. The complete combination needs to be considered.

8. The Australian Road-Use Factor

Australian performance cars are often not dedicated track vehicles.

They may be used for:

• Daily commuting
• Weekend drives
• Highway trips
• Long-distance touring
• Car meets
• Performance events

That creates a different set of priorities from a vehicle built exclusively for a racetrack.

Australian roads can include uneven surfaces, potholes, road repairs and long stretches of highway driving.

For a street-driven vehicle, the wheel and tyre setup therefore needs to provide a sensible balance between performance objectives, clearance, durability and everyday usability.

A wheel that is extremely wide may look aggressive, but if it creates constant rubbing, compromises steering clearance or requires an unsuitable tyre setup, it may not be appropriate for the vehicle's intended use.

The widest wheel is not necessarily the right wheel. The right wheel is the one that works with the entire vehicle.

9. Wider Wheels and Lowered Vehicles

Lowering is one of the reasons wheel width and offset need to be considered carefully together.

Once ride height changes, the relationship between the wheel, tyre, suspension and guard can also change.

A wider wheel on a lowered Commodore may require careful consideration of:

• Wheel offset
• Tyre width
• Tyre profile
• Guard clearance
• Inner suspension clearance
• Suspension travel
• Steering lock

This is why simply copying another lowered car's wheel specifications is not always reliable.

Two vehicles can have the same model but different suspension components, ride heights, tyre brands or wheel designs.

For a detailed explanation of how wheel position affects fitment, see our Wheel Offset Explained guide.

10. Wider Wheels Don't Replace Correct Fitment

One of the biggest changes in the aftermarket is that enthusiasts are becoming more aware of fitment as a complete system.

Wheel width is important—but it sits alongside:

• Diameter
• Offset
• PCD
• Centre bore
• Brake clearance
• Tyre size
• Suspension setup
• Guard clearance

Even the markings on a wheel only tell part of the story.

Our Wheel Markings Explained guide covers how to understand measurements such as wheel width, diameter, offset, PCD and centre bore.

For actual vehicle fitment, however, those numbers still need to be considered alongside the physical design of the wheel and the vehicle's configuration.

11. Wider Wheels and the OEM+ Approach

Not every enthusiast wants an extreme stance.

There is also growing interest in a more balanced OEM+ approach—keeping the factory character of the vehicle while upgrading the wheel and tyre package.

For Commodore and HSV builds, this can mean choosing a wider wheel while maintaining:

• Factory-inspired proportions
• Practical tyre sizing
• Appropriate ride height
• Clean guard fitment
• Performance-oriented appearance

The result does not need to look extreme to look purposeful.

In many cases, the most convincing modified builds are the ones where the wheel width, offset, tyre and ride height appear to have been designed as one package.

Read more about this approach in our OEM+ wheel trend guide.

12. A Practical Checklist Before Going Wider

Before choosing a wider aftermarket wheel, work through the following checklist:

1. Confirm your vehicle model and year.
2. Check the current factory wheel width and offset.
3. Decide how much wider you actually need to go.
4. Check the intended tyre width range.
5. Confirm the new offset.
6. Check inner suspension clearance.
7. Check guard clearance.
8. Check steering clearance at full lock.
9. Check brake clearance.
10. Consider how the vehicle is actually used.

If the vehicle is lowered or has upgraded brakes, include those modifications when asking for fitment advice.

13. Choosing Wider Wheels for Holden & HSV

For Holden Commodore and HSV owners, wider aftermarket wheels can be an effective way to create a more performance-focused wheel-and-tyre package.

Whether you're building a VE Commodore, VF Commodore, SSV Redline, HSV GTS or GTSR-inspired setup, the key is to select the wheel width together with the appropriate offset and tyre combination.

Popular staggered configurations such as 20x8.5 front and 20x9.5 rear demonstrate how wheel width can be used to create a factory-inspired performance setup.

But the exact specifications should always be checked against the individual vehicle.

Frequently Asked Questions

Are wider wheels better for performance?

Not automatically. A wider wheel can support a wider tyre where appropriate, but performance depends on the complete wheel, tyre, suspension and vehicle setup.

Why are wider wheels popular on Holden Commodores?

Holden Commodore and HSV models have a strong performance aftermarket, and wider wheel-and-tyre configurations can suit performance-oriented and staggered builds. The exact width and offset still need to be matched to the vehicle.

What is a common staggered 20-inch setup for Holden?

A 20x8.5 front and 20x9.5 rear configuration is one example used in Holden and HSV performance-style builds. However, the correct specifications depend on the vehicle, brake setup, suspension and tyre choice.

Can I fit a wider wheel without changing the tyre?

It depends on the specific wheel and tyre combination. Tyres have recommended rim-width ranges, so the existing tyre should be checked against the new wheel width before making a change.

Does a wider wheel need a different offset?

Not necessarily, but changing wheel width while keeping the same offset changes the wheel's inner and outer position. Offset should therefore be considered together with wheel width to maintain appropriate clearance.

Are wider wheels suitable for lowered Commodores?

They can be, but lowered vehicles require additional clearance checks. Wheel width, offset, tyre size, ride height, suspension travel and guard clearance all need to work together.

Do wider wheels affect ride quality?

They can, particularly when a wider wheel is combined with a larger diameter and lower-profile tyre. The resulting tyre sidewall and overall setup can change how the vehicle responds to road imperfections.

Should I choose the widest wheel possible?

No. The appropriate wheel width depends on the vehicle, tyre, offset, suspension, brake package and intended use. Maximum width is not the same thing as correct fitment.
