A Guide to Mag Wheels – Choosing & Maintenance

  • Tips/Guides-Tips/Guides


Mag wheels, also known as alloy wheels, are a popular choice among car enthusiasts due to their lightweight and stylish design. However, choosing the right mag wheels for your vehicle and maintaining them properly is crucial to ensure their longevity and optimal performance. In this guide, we will walk you through the important factors to consider when selecting mag wheels and provide useful maintenance tips to keep them in top condition.

Part 1: Choosing the Right Mag Wheels

1. Determine Your Vehicle's Fitment

Before purchasing mag wheels, it's important to check if they are compatible with your vehicle. Consider the following factors:

1.  Bolt pattern (also known as a bolt circle)

The bolt pattern of a wheel is the layout of the mounting holes. Ensure that the mag wheels have the correct number of bolt holes – It’s crucial that the pattern on the axle hub matches the  bolt pattern of your vehicle. Even a slight difference will cause the wheel to be off-centre resulting in excessive vibration while driving.

2. Offset

The offset determines how far the wheels sit inside or outside the wheel arches. Alloy wheel offset is one of the measurements that makes up its wheel fitment. It is measured in millimetres and results in a positive, negative, or zero offset.

Along with bolt pattern, offset is one of the core measurements you'll need to make sure a wheel will fit onto your car of choice. Consult your vehicle's specifications and choose mag wheels with the appropriate offset.

2. Consider the Size

Mag wheels come in various sizes, so it's important to choose the right one for your vehicle. Keep in mind the following considerations:

1. Diameter

Consider the size of your vehicle's tyres and choose mag wheels with a diameter that complements them. In this article you’ll learn the meaning of the characters on a tyre wall and where to find its rim diameter.

2. Width

The width of the mag wheels impacts the tyre's contact patch and overall handling. Take into account your driving style and vehicle's specifications when selecting the width. Read more about tyre sizes in this tyre buying guide.

3. Evaluate the Design and Finish

Mag wheels are available in a wide range of designs and finishes, from classic to contemporary styles. While certain designs also provide function in certain situations such as in the automotive sports industry, for the average consumer, it's mostly about aesthetics.

Select a design that enhances the overall look of your vehicle and matches your personal preferences. Additionally, consider the finish options such as polished, painted, or machined, keeping in mind the level of maintenance required.

Part 2: Maintaining Mag Wheels

Understanding the importance of wheel care produces a whole new level of appreciation for all-around good looks and safety.

4. Regular Cleaning

To prevent brake dust and other contaminants from damaging your mag wheels, it is essential to clean them regularly. Follow these steps:

  1. Use a mild detergent or dedicated wheel cleaner.
  2. Rinse the wheels to remove loose dirt.
  3. Scrub the wheels gently with a soft brush, paying attention to hard-to-reach areas.
  4. Rinse the wheels thoroughly and dry them with a clean microfibre cloth.

5. Avoid Harsh Cleaning Products

Avoid using harsh cleaning products or abrasive materials as they can cause damage to the surface of your mag wheels. Stick to gentle cleaners specifically designed for alloy wheels and use soft brushes to prevent scratches.

6. Apply Wheel Sealant

To protect the finish of your mag wheels and make cleaning easier, consider applying a wheel sealant. It creates a protective barrier that repels dirt, brake dust, and other contaminants. Follow the instructions provided by the sealant manufacturer for the best results.

7. Regular Inspections

Periodically inspect your mag wheels for any signs of damage, such as cracks, scratches, or bent rims. If you notice any issues, consult a professional for repairs or replacements. Promptly addressing any damage can prevent further problems and ensure your safety on the road.

8. Store Properly

If you plan to store your mag wheels for an extended period, it's crucial to do so properly to prevent damage. Consider the following tips:

  • Clean and dry the wheels thoroughly before storage.
  • Store them in a cool and dry location, away from direct sunlight.
  • Use wheel-specific covers or bags to protect them from scratches and dust.


Choosing the right mag wheels for your vehicle and maintaining them properly can greatly enhance your driving experience and the overall appearance of your car. Consider factors like fitment, size, design, and finish when selecting mag wheels, and follow a regular maintenance routine to keep them in top shape.
