Pirelli have made 2 new tyres, that should be very interesting to you chaps.
this is a snippit from the Pirelli Collezione web site https://www.pirelli.com/tyres/en-ww/car/collection
A car maker that “creates” a new series of tyres: Jaguar.
In 1977 Jaguar asked Pirelli to specifically develop the P5. Technological excellence for luxury cars, comfort and noiseless ride, highest quality: these were the characteristics that CINTURATO P5 exclusively ensured to the British sedans. In 1979 CINTURATO P5 was officially homologated in the size 205/70 VR 15 on Jaguar models XJ6, XJ12 and XJS, followed by the size 225/65R15 for Jaguar XJ40.
The prices are good too https://www.longstonetyres.co.uk/pirelli-collezione/p5.html
