Having tried numerous brands of tyres over the years at various widths, I have never noticed much difference until I fitted some Vittoria Diamante Radials, I had them in the garage for a while and was a bit nervous about fitting them as various reports said the cornering characteristics and wear was abysmal, although some write ups were favourable, all I can say is WOW, I find the comfort and low rolling resistance much better than any other tyre I have tried, they felt stable in the corners, will have to see how they wear but I am already looking to get some more (wear rate dependent) I fitted 24mm they came up at 25mm on my H Plus Son rims, it looks from reading the reports that these tyres are like Marmite you either love them or hate them, so I won't recommend them for everybody, they do run at a higher pressure than cross ply.
