I have recently acquired a set of planet-x 50mm tubs.. and because I love 25mm tyres, got a set of vittoria evo sc to go on it. I need some pointers, as I am having problems gluing these tyres on the rim, as will be described below.
The vittoria tyres are the older batch I think, its the one with a removable core and not the red removable stem. I also got a tube of conti glue to see if I can get 1 tyre on. But it was not entire (or at all) successful.. I did as the conti glue instructions said, 1 layer on tyre, 1 layer on rim, let dry for 12 hours, then another layer on tyre, another layer on rim, wait for a few minutes and mount... the result was not good at all.. I used up the whole tube of glue.. but for some reason, there is a whole lot of starved joints... the middle of the basetape where the seams "protrude" out a bit.. and that has the effect of "pushing" the tyre away from the rim, especially at the edges where it contact with the rim matters the most..there is glue on the edge of the rim, there is glue on the base tape (right to its edge)... but because of the above, its rather difficult for both the rim and tyre of them to make contact at the edges, especially when the tyre is inflated to high pressure for the final cure...
So, my question is how do i solve the above problem? Is it just a matter of using more glue, so that it will fill the space between the edge of the tyre and the rim? Does that even work to give good adhesion? I have already used 1 tube of glue for one tyre.. I thought that was enough... or do I need more or have I chosen the wrong tyre width (need narrower tyre), wrong glue or something else?
Thanks for your help
