Due to its extreme performance, the McLaren Senna features bespoke tyres developed in conjunction with technical partner Pirelli. The Pirelli P Zero™ Trofeo R tyres (245/35 ZR19 at the front and 315/30 ZR20 at the rear) are designed for dry racetracks, but are approved for road use to enable the McLaren Senna to be driven to the circuit. The asymmetrical tread pattern provides outstanding lateral grip and the special construction maintains cornering stiffness. Specific work has been undertaken on the compound to shorten braking distances, improve longitudinal performance, create a consistent reaction between the front and rear axles, and heighten on-centre steering response.
