Wowzers! toughest customer yet. A new lasertec front, plenty of soapy water.......I could not get the bead to fully seat. Just that last bit on one side. clamp the tyre and move that 'last bit' to the other side of the wheel. 100 freakin pounds! After about 6 or 7 inflations, finally. maybe I need some super duper tyre lube instead of using hand soap. Edited to add, I then of course put the wheel on my Parnes balancer only to find that I needed to rotate the tyre for a better balance. Doh!
