I’m confused; don’t find my tire size in the trade…??

Hello, I’m looking for winter tyres and I need tyres of the format 225/55 R16 99W XL. MB E220 T , 212K (first addition 28.09.11) (2.1 1313) (2.2 BHK) But I find only “V” or only summer tyres. Do I do something wrong? Can I drive other versions too? Thanks for the help Rick
