There are two main purposes of the writing that you'll see on the sidewall of your tyres. The first is to help identify the size and specification of the tyres correctly. The second is to confirm that the tyre has been tested and approved to European and other country safety standards. The European mandatory is known as 'E' marking. It is not recommended to have tyres with a lower speed rating or load capacity than the manufacturer recommended tyre specification for your vehicle.
If you are in any doubt please feel free to give us a call.
