Truck wheels endure tough conditions in Australia’s harsh climate, where road chemicals, moisture, and heat create the perfect storm for corrosion. Left unchecked, this deterioration weakens wheels, compromises safety, and impacts the appearance of your truck. With repairs costing up to $1,000 per wheel, it’s crucial to address corrosion early to protect your investment and save money in the long run.
Steel vs Alloy Wheels: What’s the Difference?
Steel Wheels
Known for their strength and durability, steel wheels are often a reliable choice. However, they are extremely heavy prone to rust, which reduces structural integrity, and detracts from your truck’s appearance.
Alloy Wheels
Chrome alloy wheels are increasingly popular due to their lightweight design and superior corrosion resistance. They also run cooler, improving efficiency and reducing wear. While they resist rust better than steel, alloy wheels still require regular maintenance to prevent iron deposits from brake pads damaging their surface. If you’re considering upgrading, explore the range of Armoury Wheels for a durable and stylish solution.
What Causes Corrosion?
Corrosion might seem unavoidable, but understanding its root causes can help you minimise the risk and protect your wheels. Let’s explore the primary culprits and how they lead to damage.
Iron Contamination
Brake pads release microscopic, hot iron particles during braking. These particles bond to the wheel’s surface, compromising the protective coating. Once the coating is damaged, corrosion begins to form, weakening the wheel’s structure and tarnishing its appearance.
Pitting Corrosion
Road chemicals, salt, and debris can gradually erode the factory-applied protective layer on wheels. This process leads to pitting corrosion—tiny craters that weaken the surface. Left unchecked, pitting can result in air leaks or even material failure.
Incorrect Maintenance

Acid-based cleaners and abrasive scrubbing tools are often culprits in corrosion. These harsh methods strip away the protective layers on your wheels, exposing them to moisture and rust. Over time, improper cleaning techniques can lead to permanent damage.
How to Prevent Corrosion
Preventing corrosion requires consistent care and the right techniques. While we’ve highlighted the causes, for a deeper dive into maintaining your wheels, don’t miss Part 2: Taking Care of Your Alloy Truck Wheels, where we explore cleaning methods, choosing the right products, and avoiding common mistakes.
