Tyre Symbol Guide - OE Manufacturers
Tyres can come in all shapes and sizes (usually round!) and even within the same model, they can have different materials added/subtracted to tailor to different vehicles! For example, a Tesla will need to have tyres designed for the instant torque provided by the electric motors of the vehicle compared to an Vauxhall Astra of the same size.
Below are many, but not a complete list, of different tyre fitments that can come from a manufacturing facility. It's always recommended to have the specific fitment for your vehicle but is not essential. These different fitments can also cross-over to different vehicles!
*Porsche vehicles, due to their warranty, should remain on their 'N' rated tyres as specified from factory. However, you as the client have the ultimate decision.
