New Pirelli Diablo Rosso IV Corsa supersport tyres announced

NEW Pirelli Diablo Rosso IV Corsa hoops have been announced for 2022, marking the introduction of the sportiest tyre in the Rosso family – and just in time for the firm’s 150th anniversary.

Arriving complete with special edition 150th anniversary logos on the tyre’s sidewall, the new Corsas represent a marked improvement over the current top-spec Rosso hoops. They are still designed for use on the road and track and feature an all-new design that is said to boost grip, feel and feedback and tyre consistency over prolonged high-speed use.

The tyres sit between the track-day favourite Supercorsa SP and standard Diablo Rosso IVs in the Pirelli range. A new tread arrangement increases the land-to-sea ratio, with more rubber sitting on the road for more of the time. The multi-compound approach, as has been the way for some years now, still sees the stickiest rubber reserved for the shoulder, while a silica-rich centre band should increase tyre life over those more mundane journeys.

A totally redesigned carcass includes a sharper crown that is claimed to be a faster and more responsive tyre during fast direction changes. The shoulder of the tyre is also flatter than before, aiding edge grip and feel. Pirelli has used a symmetrical approach to the design, meaning the front and rear follow the same design mentality and therefore characteristics.

Further changes to the carcass include a new design structure for the internal cords. Pirelli describes this ‘stiff cord technology’ as having more rigidity than before with 20 percent less density than the old Rosso IIIs. The new design leaves more room within the carcass for rubber as opposed to structural cords. Pirelli is claiming this new minimalist approach will increase feel and feedback thanks to the increased damping properties of the extra rubber.
