The Dunlop Sport Maxx RT in size 225/40R19 93Y XL is a "Max Performance" summer tyre. The MO marking (Mercedes Original) signifies it was co-developed with Mercedes-Benz for the C-Class (W205) and E-Class, while the DOT22 confirms it was manufactured in 2022.

The "RT" stands for Racing Technology, highlighting its motorsport DNA. Though the newer RT2 is available, the original RT is still produced in specific sizes like this one to maintain factory-spec performance for high-end European vehicles.
