The Dovroad / Prozax Sport 275/40ZR20 is a budget ultra-high-performance (UHP) tyre for large sedans and performance SUVs (BMW 5/7 Series, Mercedes E/S-Class, Audi A6/A7, etc.).
It sits in the same category as other low-cost Chinese UHP tyres—built to look sporty and handle normal road speeds, but not designed to match premium tyres in safety consistency or long-term durability.
