Very smooth and one of the grippiest tyres I've ever used. So grippy they're fairly noisy and I assume not 'that' fast rolling due to this. Extremely supple and don't ballon to a silly size.
My GP5Ks are much quieter and I would say roll a fair bit faster, but who knows until the tests come out.....
Well, the 2018 Corsa have the lowest rolling resistance in tests
