Why change to alloy wheels?

  • Alloy wheels reduce the unsprung weight of a vehicle, giving you more controlled steering and reduced fuel consumption.
  • Alloy wheels are excellent conductors of heat, improving heat dissipation from the brakes and reducing the risk of brake failure under demanding driving conditions.
  • Using the “Inch-up Principle” (increasing the diameter size of the wheel fitted by the manufacturers) when buying alloy wheels, optimises steering response and road holding, especially when cornering.
  • A set of alloy wheels will make your car look great!


The principle of conversion:
The larger the wheel, the larger the tyre.

This inversely lowers the tyre profile, because the original rolling radius of the car cannot be changed (rolling radius is the distance it takes for the wheel to make 1 complete revolution).

In other words, if a car has a rolling radius of 2.050mm, after changing the wheels and tyres the radius needs to remain 2.050mm. The whole car from brakes, suspension and the gearbox is set up for this.
If a change occurs the car will experience mechanical problems but more importantly features like ABS won’t work correctly. You could even have the speedometer indicating 120km/h but in reality you’re driving at 140km/h!

Using this principle you can upgrade your wheels yet remain as close as possible to your original technical specifications. Never convert to a smaller size than the original fitted on your car.

Increasing your wheel size gives you 3 advantages:

  1. Optical: The look of the car improves immediately – makes it more attractive!
  2. Security: Braking distance can be reduced by up to 7%(3m) due to the larger sized wheel and wider tyre.
  3. Driving improvement: With a larger wheel and of course a lower tyre profile the car becomes more stable.

Choosing the correct wheel

  1. The wheel must complement you type of car (design, colour etc.)
  2. The wheel must be manufactured to fit properly.
