I've gone for 700c x 25 Vittoria rally training tyres, black tread with amber sidewalls. They seem a little heavier duty construction than some tubs which I'm hoping will cope with my poorly maintained and heavily pot-holed local Oxfordshire roads!
They also have very small logos on the tyres compared to the tufo brand, and can be easily painted over.
I'll be fitting the tyres this coming weekend and will post the results then.
I'm hoping they'll fit fine, but although both are ostensibly 700c size the rear rim is some 43 mm larger in circumference.
