The Grenlander 245/45ZR17 (usually Enri U08 99W XL) is a budget ultra-high-performance summer tyre made for sedans and sporty cars like BMW 3 Series, Mercedes C-Class, Audi A4, and similar vehicles.
This size is quite sensitive because it’s a low-profile performance tyre, so the main concerns are wet grip, braking confidence, ride comfort, and sidewall strength (XL rating matters here).
