The exact dimensions of a tyre can be found on the sidewall printed mark. The graphic shows how to read properties and dimensions of the tyre:
Extra Load / Reinforced
Extra Requirements: Reinforced, RE, Extra Load or XL.
Van tyres / C-type
Marking on tyres with additional load capacity (e.g. vans, small transporters, small buses, off-road vehicles and fast cars with V tyres). The important factor here is the higher load index number. Reinforced tyres require more air pressure than the standard version of the same tyre.
Original Equipment Quality: Optimally calibrated to the car
Tyres with a special OE marking on the sidewall are tyres that have been developed in cooperation with a specific car manufacturer and the tyre industry. These tyres have been specifically designed to suit one car model perfectly. Optimised to improve the individual strengths of the specific car, they represent the height of the latest tyre fine tuning process, a process complements that newest developments in the automotive industry.Naturally, OE tyres may also be used on cars other than the model they were designed for.
