Are you checking whether your wheels are safe for daily driving or special occasions like the upcoming Valentine’s Day? Upgrading your vehicle with aftermarket wheels is a popular choice for drivers in Australia and beyond. But are aftermarket wheels truly worth the investment, and are they safe for everyday use?

A new set of tires is one of the most cost-effective ways to enhance your car’s performance, and pairing them with fresh wheels can significantly improve its appearance. However, before purchasing aftermarket wheels and tires, you need to consider several factors to ensure they fit properly and safely under your vehicle. Let’s dive into the details to help you make an informed decision.

What Are Aftermarket Wheels?

Aftermarket wheels are rims that are not made by the original equipment manufacturer (OEM) and are typically manufactured by a third party. They offer a wide range of designs, sizes, finishes, and materials, catering to drivers looking for customization, performance enhancements, and unique styling. Furthermore, adding aftermarket tires and rims to your vehicle can decrease fuel economy, hinder acceleration, affect ride quality, and alter steering geometry, among other effects.

Key Factors Affecting Safety

1. Material & Construction

The world of wheels can be very confusing. Knowing the material and manufacturing process can help you determine the strength, durability, and weight of the wheel. Aftermarket wheels are typically made from steel or aluminum alloy so consider your driving habits and road conditions in Australia to determine the best material.

✅ Example of a Safe Choice: Forged Wheels – These are stronger and lighter than cast wheels, forged wheels are ideal for both performance and daily driving. They get their name from the forging process, where a single piece of aluminum is compressed and shaped into a wheel under high pressure. Mars Performance produces high-quality forged wheels designed to withstand the demands of everyday use. 

❌ Example of an Unsafe Choice: Cast Wheels – While strong enough for occasional track use or casual trips to the beach in an SUV or small car, cast wheels are mass-produced and made with lower-quality materials. Their manufacturing process increases the risk of cracking or bending under stress. Additionally, they are more porous, meaning the metal may contain inconsistencies that weaken the wheel over time.

2. Load Rating & Weight Capacity

Heavy wheels can negatively impact your vehicle’s acceleration and handling performance. Every wheel must support the vehicle’s weight and forces while driving. Using wheels with an insufficient load rating can cause structural failure, and that’s not a safe practice with wheels.

✅ Example of a Safe Choice: If a car weighs 1,500 kg, each wheel should have a load rating of at least 375 kg. Manufacturers determine load ratings based on weight distribution and the vehicle’s intended use. 

When calculating the total load, consider the weight of passengers, cargo, and aftermarket modifications. Before you purchase aftermarket wheels, always check the manufacturer’s specifications before purchasing.

❌ Example of an Unsafe Choice: Installing lightweight racing wheels (designed for track use) on an SUV can cause premature failure due to excessive weight.

3. Wheel Fitment & Offset

Knowing the right wheel fitment is important for your daily drive. Incorrect wheel fitment can cause issues like poor handling, rubbing against fenders, or excessive stress on suspension components. Furthermore, it will show the clearance between the inside of the wheel and the strut housing, which is essential for safe and efficient vehicle operation.

✅ Example of a Safe Choice: Choosing the correct offset ensures perfect wheel fitment. A Toyota 86 with 18x8.5 +35 offset wheels fits properly without affecting suspension geometry or causing rubbing. With the right fitment, you can drive confidently on streets and trails without causing accidents. 

❌ Example of an Unsafe Choice: Using the wrong offset can damage both the rims and tires. Installing 20x10 -12 offset wheels on a Mazda 3 can cause fender scrubbing, poor handling, and premature suspension wear.

4. Certification Standards (JWL, VIA, TUV, DOT)

Certified wheels undergo rigorous testing to ensure they meet safety standards.

✅ Example of a Safe Choice: Wheels with JWL, VIA, or TUV certification pass rigorous impact and fatigue tests. Many Mars Performance wheels meet these standards, ensuring long-term safety and durability.

❌ Example of an Unsafe Choice: Cheap replica wheels may seem like an affordable upgrade, but they come with serious safety risks. Many uncertified replica wheels sold online lack proper safety markings, meaning they skip essential manufacturing and testing processes. Furthermore, unsafe wheels are more likely to crack or even shatter under heavy impacts or high torque, in the short term it may increase the risk of accidents.

Choosing the Right Aftermarket Wheels for Daily Use

Safety is a top priority when installing aftermarket wheels, especially for daily driving. Knowing the right information about your wheels means you’re making an extra mile effort in ensuring the safety of both you and your passengers. With so many wheel options available, follow this list to make a safer choice and understand the importance of the right wheels.

1. Prioritize Safety & Durability

• Choose forged or flow-formed wheels for strength and longevity.
• Ensure the wheels meet JWL, VIA, or TUV certification standards for safety.
• Check the load rating to match or exceed your vehicle’s weight requirements.

2. Get the Right Fitment - Ensure proper fitment to avoid issues like poor handling or rubbing against fenders. 

3. Balance Performance & Aesthetics

• Lighter wheels improve acceleration, braking, and fuel efficiency.
• Consider wheel size carefully—larger wheels may look great but can impact ride comfort.
• Opt for a coated or corrosion-resistant finish to withstand daily wear and harsh weather.

Still wondering if aftermarket wheels are safe? Our answer for you is that the safety of aftermarket wheels largely depends on the quality and fitment of the wheels you choose. High-quality aftermarket wheels that are properly fitted can be just as safe as OEM wheels. However, you must do thorough research, choose reputable brands like Mars Performance aftermarket wheels, and ensure proper installation to avoid potential issues.

In conclusion, aftermarket wheels can be a great way to enhance the look and performance of your vehicle, but you must weigh the pros and cons carefully before purchasing. By making informed choices and prioritizing safety, you can enjoy the benefits of aftermarket wheels without compromising on daily driving safety.
