Checking all four current tyres on your vehicle is very important as it will avoid delays and save you money. Use 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 RunFlat Tyres? Check if your vehicle has an "RFT" "MOE" on the tyre sidewall. Vehicles that usually require RunFlat tyres are BMW, Mercedes, MINI & 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.
Where do I look for the tyre size on my vehicle's tyres?
What do the above markings mean?
Width - The tyre width measured in millimetres. In this example, the width is 185.
Profile / Aspect Ratio - 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 (55% of 185mm). In the example above, the profile is 55.
Rim Diameter - The diameter of the wheel rim measured in inches. In this example, the rim diameter is 15.
Load index - The load index on a tyre lets us know what the maximum load-carrying capacity of that tyre is and each vehicle has a minimum load-rating requirement set by the vehicle's manufacturer. Any tyre fitted to the vehicle must meet or exceed this requirement to ensure safety and roadworthiness. To find this load index, check your Tyre Placard and/or your current tyres on your vehicle. In this example, the load index is 81.
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 is the maximum tested speed in which the tyre can operate. in the above example, the H indicates the tyre has a maximum speed limit of 210kph.
Speed ratings are relevant in certain European countries where highways do not have speed limits. In Australia, it is necessary to make sure the tyres fitted to a passenger car meet a minimum speed rating of 180 kph or (S) speed rating. For off-road vehicles, a minimum speed rating of 140kph or (N) is required.
For example, A Holden Commodore can use a speed rating of H (210kph) if the placard states a V (240kph) speed rating. A Toyota Landcruiser may have a speed rating of T on the placard; however, an R speed rating can be used. If you have any concerns, please consult your local authority/insurance company or contact Tyresales.
I have a Z Speed Rating on my current tyre, what does this mean?
Z speed rated tyres are capable of speeds in excess of 240kph. When introduced, the Z speed rating did not indicate a maximum speed, as it was thought that speeds over 240kph would be more than sufficient as a maximum speed.
While Z rated tyres still exist, these tyres will also contain a speed rating in the service description (usually W or Y) to indicate the maximum speed capabilities of the tyre.
Although we do not display the Z rating online, many of the tyres with a speed rating above a V will have a Z speed rating on the tyres.
