The 275/45 ZR20 specification combines a 275 mm section width with a 45% aspect ratio and a 20-inch wheel diameter. The relatively wide footprint is suited to high-performance vehicles where lateral grip and steering stability are important. The exact tyre has an overall diameter of approximately 29.8 inches, or around 757 mm.

110Y XL Load and Speed Rating

The 110 load index corresponds to a maximum rated load of 1,060 kg per tyre. The Y speed rating corresponds to a maximum rated speed of 300 km/h. This tyre is also marked XL, or Extra Load, indicating reinforced construction designed for increased load capacity.

Asymmetric Tread Design

The Potenza Sport uses an asymmetric tread pattern developed to balance dry handling with wet-road performance. The tread layout incorporates rigid ribs and optimised grooves to maintain contact stability while helping evacuate water from the contact patch.

Dry Handling and Braking

Dry-road performance is a major focus of the Potenza Sport. Its performance-oriented tread and reinforced construction are designed to provide responsive steering, strong cornering stability and effective braking when driving on dry surfaces.

Wet Performance and Water Evacuation

The tread design incorporates circumferential grooves and carefully positioned lateral grooves to help remove water from beneath the tyre. The exact 275/45 ZR20 110Y specification carries an A rating for wet grip under the European tyre-label system, reflecting its strong wet-braking classification.

Steering Response and High-Speed Stability

The reinforced XL construction and performance-oriented tread support a direct steering response and stable behaviour during high-speed driving. The tyre is designed to maintain structural rigidity when subjected to lateral forces generated during cornering.

Rolling Resistance and Road Efficiency
