New Continental Hardshells Having difficulty bedding my new Gatorskin tyres onto the clincher wheels of my audax bike. Campag Scirrocco wheels. There is a constant 'dip' in the tyre at the same point despite numerous reinflations.
Continental tires have a tendency to do this, especially when new. It's very common. Put some soapy water on the bead and temporarily overinflate. That will usually get them to seat.
