I'm considering swapping out the 32mm GP5Ks with 35mm Pirelli Cinturatos for my rain bike. Is going that wide overkill? I think that the bike in question has tire clearance for them, since there's more of a gap between the fenders and the GP5Ks than what would please my aesthetically.

Besides looks, I'm after better safety, like better grip and braking in wet conditions. As I posted earlier in the thread, the GP5Ks were easy to seat on my Hunt alloy wheels but lose a lot of air overnight and won't stay bead-locked when at low pressure. Schwalbe Pro Ones (first gen, 25mm) that I have on the DT Swiss rims of a different bike have no such air loss issues, but one did require a blast of CO2 to seat. The rear Pro One finally got a puncture that I noticed. It sealed on its own but has me thinking of the eventuality that I'll move the GP5Ks over when the Pro Ones wear out, with the hope that the tire-rim combo retains air better than on the Hunts.
