Looking for some advice on getting my tyre to sit nicely on its bead. The tyre in question is just a turbo trainer tyre on a spare wheel for the odd occasion that I can't actually get out and fancy giving my legs a spin the problem is that with my old dumb trainer I never noticed the tyre running a wee bit out but I bought myself a tacx vortex a couple of months ago and as it needs to be calibrated by adjusting the roller the tyre gives a sort of on/off feel.
I've tried windowline which has always been fine on other tyres and wheels, I tried soapy water and finally just washing up liquid on its own but still no joy. I've pumped it up to 85psi and nothing and the tape is central so shouldn't come into play. The wheel has a very slight side to side movement but no flatspots.
Any help appreciated
moare psi
I've put it up to 95 which is the tyre maximum but it's an old wheel so not sure how high I could/should push it
My mtb wheel tyres difficult to seat, I've found pumping it to max PSI, and then bouncing the wheel on a hard surface like a basket ball helped it pop into place.
Or even just riding on it at high pressure it will pop in eventually, although you probably won't be able to bully it into place on a smoth turbo trainer.
Then just readjust pressure.
If all the above options fail then you may wish to try this method which has worked for me.
Pump up the tyre to whatever the normal pressure should be, then identify where on the tyre the bead hasn't seated and is still tucked inside the wheel. Look for moulded lines along the sidewall of the tyre which aren't parallel to the edge of the rim.
When you've identified where the bead isn't seated properly put the tyre on the ground in front of you so that your hands are at the top and you are facing the side of the wheel. The bit of unseated bead should be facing you at the bottom. Put the tip of your trainer on the outside of the tyre sidewall where the bead isn't seated and apply a little pressure with your toe to gain purchase on the rubber, against the ground. Then using your hands gently roll the tyre away from while gripping the sidewall with the tip of your trainer. The bead should (hopefully) be pulled into place with a gentle pop.
Easy does it, and keep the tip of your trainer pressed on the sidewall but off the wheel rim. A gentle roll away with the arms is usually enough.
