Just finished a wheel with Ambrosio P20 rim, put a tubed Gravelking 32 slick on (really tight) and it won't seat properly - one side of the 'bead' always favours the channel in the centre of the rim (much deeper than other rims it seems?) Have tried: riding around at 30 psi to squeeze it out to its place/ rolling by hand/ increasing pressure to 100psi to pop it in - no luck. Thought about slicing a rim tape in half to pack out that middle channel a bit so it's relatively a bit less attractive a place for the bead to sit, but someone here maybe has other tips?
