These tyres are mind blowingly good, so good in fact that I’m still struggling to get my head around just how exceptional they are. The tyres you see here – a soft front and an endurance compound – have just come back from three hot days on track at Jerez, and their performance is simply staggering around the circuit’s 2.75 miles of gloriously fast straights, late apex technical twists and turns. Scrubbing in takes just one lap, and they have so much grip I’m able to push hard straight away around every single one of the 13 corners. I don’t use tyre warmers, but these tyres allow me to stay with – and ride past – those riders who are. Once they’re up to working temperature they’re superb; they’re stable and offer supreme levels of confidence inspiring grip. And the amount of heat they generate and retain is astounding. What did become clear as the day progressed is that they’re sensitive to pressures, and will quickly tear if over or under inflated. I thought they were cold tearing initially, but the opposite was true, and once I’d adjusted the pressure they responded straight away and came back to me. They’re also incredibly durable. I went faster than I’ve ever been and after three blisteringly hot days on track they’re still good, despite having covered some 450 hard miles. Recommended.
