My cyclocross wheels (Mavic A719, XT hubs) pop when I pump the Gatorskins to 120. If I keep them at 100 no noise. Recently had the wheel retensioned (w/o the tires - Dohh!) and still the problem exists. So what gives? I can't believe the tire is compressing the wheel or making it rounder (or less round). Anybody else tension their wheels with the tires on and inflated?
