When you are towing, touring or covering long stretches of highway, wheel alignment can have a bigger impact on fuel economy than many drivers realise.
If your wheels are not sitting at the correct angles, your tyres may not roll as freely as they should. Instead, they can drag, scrub or fight against the road surface. That extra resistance can make your vehicle work harder, wear your tyres unevenly and potentially use more fuel than it needs to.
A wheel alignment is not just about keeping the steering wheel straight. It is an important part of keeping your vehicle safe, efficient and easier to drive.
What Is Wheel Alignment?
Wheel alignment is the adjustment of your wheels so they sit at the correct angles in relation to your vehicle, your suspension and the road. When your wheels are properly aligned, your tyres can roll straight and make even contact with the road surface.
Over time, your alignment can be knocked out by everyday driving. Hitting a pothole, driving on corrugated roads, towing heavy loads, or worn suspension components can all affect the way your wheels sit.
A proper wheel alignment helps make sure your vehicle tracks straight, your tyres wear evenly and your steering feels right.
How Poor Wheel Alignment Creates Drag
When your wheels are out of alignment, your tyres may not point in the direction they are meant to. They might be angled slightly inwards, outwards or sitting unevenly on the road.
Even if the difference looks small, it can create extra drag. Instead of rolling smoothly, the tyres can scrub across the road surface as the vehicle moves forward. This is a bit like trying to push a shopping trolley when one wheel is fighting against the others. It still moves, but it takes more effort.
On a 4WD or touring setup, that extra resistance can be even more noticeable because the vehicle is often already working harder. Add the weight of a caravan, boat, trailer, tools or touring gear, and the tyres need to be doing their job properly.
Poor alignment can also make the vehicle pull to one side, feel heavier through the steering or feel less settled on the road.
That means your tyres, suspension and steering components are not working as smoothly together as they should be.
Why Extra Resistance Can Increase Fuel Use
Your engine’s job is to move the vehicle forward. When your wheels and tyres are rolling properly, the vehicle can travel more efficiently. When the tyres are dragging, scrubbing or creating extra resistance, the engine may need to work harder to keep the vehicle moving.
That extra effort can contribute to increased fuel use, especially over longer distances. You may not notice it on one short trip around town, but if you are driving hundreds of kilometres across WA, towing a caravan or regularly travelling with a loaded vehicle, small inefficiencies can add up.
Fuel economy is not just about saving a few dollars at the bowser. It can affect how far you can comfortably travel between fuel stops, how your vehicle performs under load and how much strain is placed on your tyres and suspension.
Poor wheel alignment is not always the only reason a vehicle uses more fuel, but it can be one of the factors. If your vehicle is suddenly using more fuel than usual and your tyres are wearing unevenly, your alignment is worth checking.
Poor Alignment and Uneven Tyre Wear
One of the biggest signs of poor wheel alignment is uneven tyre wear. When your tyres are not sitting correctly on the road, certain parts of the tread can wear faster than others.
You might notice wear on the inside edge, outside edge, feathering across the tread or patchy wear that does not look normal. This is a sign that the tyre is not making proper, even contact with the road.
Uneven tyre wear can become expensive quickly. Good quality 4WD, all-terrain and touring tyres are not cheap, and poor alignment can shorten their lifespan. If you are preparing for a long trip, the last thing you want is to discover your tyres are wearing badly halfway through the journey.
How Uneven Tyre Wear Makes the Vehicle Work Harder
Once tyres start wearing unevenly, they may not roll as smoothly as they should. This can create more road resistance, affect handling and reduce how stable the vehicle feels.
A tyre with uneven wear may also create more vibration, noise or steering correction. Instead of the vehicle tracking cleanly, you may find yourself constantly making small adjustments to keep it straight.
For vehicles towing a caravan, this matters. Good tyre contact, stable handling and predictable steering all help the vehicle feel more controlled on the road. If your tyres are wearing unevenly, the whole setup may feel less comfortable and less efficient.
Poor alignment can start the problem, and uneven tyre wear can make it worse. That is why it is always better to catch alignment issues early, before they chew through a good set of tyres.
How Wheel Alignment, Tyre Pressure and Suspension Work Together
Wheel alignment is only one part of the picture. Tyre pressure, suspension condition and vehicle load all affect how your tyres sit on the road and how efficiently your vehicle drives.
If your tyre pressure is too low, your tyres can create extra rolling resistance and generate more heat. If your tyre pressure is too high, you may reduce the tyre’s contact patch and affect ride comfort and handling. Both can lead to uneven wear.
Your suspension also plays a major role. Worn shocks, sagging springs or an unsuitable suspension setup can change how the vehicle sits, especially when loaded.
This can affect wheel alignment, tyre contact and overall stability.
For 4WDs and touring vehicles, this is particularly important. Once you add extra gear such as a canopy, tools, camping gear, and more, your vehicle may sit very differently compared to standard. If the suspension is not suited to the load, your tyres and alignment can suffer.
That is why it is worth looking at the whole setup, not just one part. A proper check can help identify whether the issue is alignment, tyre condition, suspension wear or load-related.
When Should You Get a Wheel Alignment?
Poor wheel alignment can create drag, make your vehicle work harder, increase uneven tyre wear and potentially contribute to higher fuel use. For WA drivers, especially those travelling long distances, towing caravans or driving loaded 4WDs, it is a simple maintenance step that can make a big difference.
