Tyre Size Guide
Checking all four current tyres on your vehicle is very important and recommend using the below checklist to ensure your order is correct.
Do you have two different tyre sizes on your vehicle?
Double check your front and rear tyres to see if you have different sizes.
Does your vehicle need Run-Flat Tyres?
Check if your vehicle has an "RFT" "MOE" on the tyre sidewall. Vehicles that usually require Run-Flat tyres are BMW, Mercedes, MINI Cooper & Renault.
Do you need Commercial or Light Truck tyres? These will have the letter "C" or "LT" written in the size on the sidewall of your current tyres (e.g. 195R14C or LT35X10.5R16 123)
Does your current tyre size on your vehicle match your ordered size?
When you are looking at your tyres on your vehicle, check to make sure that your Width, Profile, Rim, Load and Speed rating match.
The example below has a tyre size of 225/60R16 98H. Where the numbers appear in the example below is how your current tyre number will appear on the tyres you have fitted to your vehicle.
What do the above markings mean?
Width (A) - The tyre width measured in millimeters. In this example, the width is 225.
Profile / Aspect Ratio (B) - The profile is the depth of the tyre sidewall. This measurement is taken from the wheel to the outer circumference of the tyre and is a percentage of your tyre's width (60% of 225mm). In the example above, the profile is 60.
Rim Diameter (C) - The diameter of the wheel rim measured in inches. In this example, the rim diameter is 16.
Load index - The load index on a tyre lets us know what the maximum load-carrying capacity of that tyre is. You are able to order a load index that is the same or above your vehicle's standard requirement is. To find this load index, check your tyre placard and/or your current tyres on your vehicle. In this example, the load index is 98.
Where is my Tyre Placard? The tyre placard is usually a sticker that is located on the driver’s door/doorframe, petrol lid or glove compartment.
Speed rating - The speed rating of a tyre lets us know the maximum speed in which the tyre has been tested corresponding to the tyres load index. Speed ratings were established to match the speed capability of tyres with the top speed capability of the vehicles to which they are applied.
While tyre manufacturers can produce tyres capable of very high speeds, it is not recommended to use the tyre in excess of the legal speed in your state or territory. In this example, the speed rating is 210km/hr / H rated.

What is the best way to find new tyres for my vehicle?
The best way to purchase the correct new tyres for your vehicle is to check the tyres you are currently using. Use the information above and match that with your search values on the website by size.
You can use the vehicle search on the website, but please be aware that this search method provides tyre information based upon original equipment for the vehicle entered by you. The result may not be accurate for what you actually require.
To avoid ordering the wrong tyres we strongly advise you to check your tyre's current size and the tyre placard in your vehicle.
Run-Flat tyres provide an extra layer of safety and are designed to be driven on for a certain distance after a tyre loses pressure. After losing tyre pressure, the driver must maintain a steady speed of no greater than 80km/h, for a maximum distance of between 50km - 80km (depending on the tyre brand).
Run-Flat tyres may only be fitted onto vehicles specifically manufactured to accommodate Run-Flat tyres and these vehicles always have a functional Tyre Pressure Monitoring System (TPMS). Typical vehicle manufacturers that utilize Run-Flat tyres are BMW, MINI, Mercedes and Renault. If you currently have Run-Flat tyres, you will see the letters 'RFT' written on the sidewall of your tyres.
Please note - a specialized fitment centre or Dealer should carry out the fitting of Run-Flat tyres.
Commercial & Light Truck Tyres
Some Commercial or Light Truck vehicles require Commercial or Light Truck-rated tyres. These tyres will display a "C" after the rim size or an "LT" before the width measurement on the sidewall of your current tyres - e.g. 195R14C or LT35X10.5R16.

Mercedes Original Equipment Extended Mobility (MOE) Tyres
Tyres marked with MOE are specially designed for Mercedes vehicles. This provides a limited run-flat capability - usually operating in a lesser capacity to run-flat tyres and should only be used on Mercedes vehicles.
Mercedes Benz vehicles equipped with MOE tyres must not be replaced with other tyre variants.
