I have been having trouble getting a fresh tire onto a road bike wheel. The tire is "continental Grand Sport race 23mm" and the bike is a scattante road bike. I have looked at tips and watched videos including this onebut the part I am having trouble with (currently) is the first bead, which everything seems to skip over, saying it is "easy." I have tried it both with inflating the tube somewhat and trying to put on the tire with the tube already in it, like in the above video, and just the tire itself. I make less progress with the tube. I can get the tire about 6/8 or 7/8 of the way around and no amount of pushing, pulling, and general finger destroying will get it on. Is there anything I can do? Thanks.
