I have had bad luck recently with tyres blowing off old 27 inch rims - and often splitting the carcass of the tyre from the wire bead - with a very loud bang shocking passers by. This has happened with Panaracer 27 x 1 1/4 and 27 x 1 1/8 tyres and with Continental Ultra Gatorskin tyres - on both Fiamme and Weinmann Alesa rims.
Are there tyres which don't suffer so badly from this? Or is it just a matter of tyre pressures? My blow-offs have happened with the tyres at about 75 psi. Is it necessary to go lower than this?
