The Rotalla Setula S-RACE RU01+ (often categorized interchangeably with the RS01+ in this size) in 245/35R21 96Y XL is a budget-focused Ultra-High Performance (UHP) summer tyre. It is designed for drivers who need a massive 21-inch fitment for performance vehicles—such as the Tesla Model S, Audi A7/S7, or BMW 7 Series—without the high "premium brand" price tag associated with 21-inch rubber.

The RU01+ represents an evolution in Rotalla’s lineup, focusing on improved structural integrity for the larger rim diameters now common in 2026.
