I'm having a weird problem that I can't figure out. I am trying to put new tires on a rim but when I get above 80 psi the tube pushes the tire off of the rim.
- rim is a 700c Araya from an older road bike (early 1990s)
- tire is a Vittoria Open Corsa Evo CX
- tube is a Bontrager 27x 7/8 - 1; 700x18c - 25c
I have used Vittoria tires before...this model is described as "open tubular" but I thought that they would work fine with this type of rim.
I have maneuvered the tire back and forth to get the tube seated and I have mounted a lot of tires and never had this problem.
