More pressure until they jump to place. Always found these a bit baggy but for really tight fittings I always squirt some soapy water or alcohol in the unseated part, pump to unreasonable PSI. Repeat as many times as necessary, but don't leave your gravel tires pumped at 100 PSI, release as soon as it seats.
