A Guide to Alloy Wheel Selection

Your vehicle’s rims are some of its most noticeable components, and your wheel choice has a significant effect on your car’s performance. Changing to Tuff wheels can help you achieve the performance you’re looking for, and it can change the style and look of your vehicle. To choose the right rims, you should know just what they are, how they fit into multi- and single-piece wheels, and how to pair them with the right tyres. Once you have increased your rim knowledge, you can find the right ones from a local vendor.


What are Rims?

Some people are confused as to what rims actually are. Many use the terms “wheel” and “rim” interchangeably, but this can lead to mistakes when choosing wheels. The rim is the wheel’s outer edge, which holds the tyre in place so it can turn with the wheel, and it connects to the hub via the spokes. For the purposes of this instructional guide, “rims” are aftermarket wheels bought to upgrade from factory equipment.


Multi- and Single-Piece Wheels

You can buy rims as part of a single-piece wheel set, or you can buy them separately to fit multi-piece wheels. Many wheel makers cast rims, hubs and spokes together as a single piece, while others cast parts separately and attach them later. Single-piece sets usually cost less than multi-piece wheels, but they require total replacement if damage occurs to one part of the wheel.


Matching Rims and Tyres

If you want to keep your current tyres and buy new Koya wheels, it’s important to match the new rims to the tyres. In most instances, the rim/tyre combo’s overall diameter won’t change even as the rim’s diameter increases, which you can do by choosing tyres with shorter sidewalls. Pay attention to rim width, which should be roughly the same as the tyre width. You should also ensure that the new rims match the old set’s bolt pattern to ensure compatibility with your vehicle.


Choosing Rims According to Style and Performance

Your car’s rims have a significant impact on its looks and performance. Learning how a set of rims can affect a vehicle’s style and drivability can help you make the right decision.


  • Size: Increasing rims’ diameter typically shortens tyre sidewalls, improving road grip and vehicle handling. However, raising the overall radius of the rim and tyre can slow the vehicle down and decrease the potency of its antilock braking system.
  • Materials: Most rims are made of steel or aluminium. The latter weighs less, which can help increase fuel economy, but the former is heavier and more durable. Heavier rims can diminish ride quality.

When you choose alloy wheels for your car, your options are nearly limitless. Aftermarket manufacturers create countless designs with different colours and spoke patterns, and you’re sure to find one that’s a perfect match for your driving habits and your needs.
