19mm vittoria tyres

i own a pristine1995 Bianchi endurance bike originally bought with vittoria 19mm tyres.having gone through several tyres over the past - 2 years although only ridden on high days and holidays - i am finding replacement 19mm tyres very difficult and expensive to come by. is it safe to fit 23 mm vittoria tyres on to the original Ambrosio / Campagnolo wheels?

    I don't see why not if there's clearance for them in the frame.

    Tubs or clinchers?

    once I inherited an 18 mm tubular... it was about the same size as a line of toothpaste... frightening to think of riding on that

    I think I have a 19mm on a HED disc wheel in the loft. Its kinda narrow but nothing cackworthy tbh....

    You only need big tyres if you're a fat knacker.

    Oi. Sizeist! I'm offended, on behalf of... apart from myself...

    teams used to ride Roubaix on 19mm - shudder to think of that now. if you have clearance 23mm will be fine or even 25mm

    25 is the new 19

    17mm and 130 psi. That's the ticket.

    Still very difficult to beat 23 and 120.....
