Got some pro’2 on 819 rims last week.
Not got the cash for ust tyres at the mo, so got some stans fluid and stuck it in a panaracer xc fire on the front and it inflated and popped onto the rim…held pressure and survived a quick ride so all good.
the back (same rim/tyre set up) will not go on at all, used the tube in, inflate, leave it overnight, break 1 bead remove tube add stans etc and inflate, it just wont go up, tyre bead seems to be sitting in the middle of the rim and not pushing out to the rim so wont take air at all… I take it just wont work at all? (tyre is the same age as the front – 6/7 rides old just)
