Tyres not seating in rims!

[akneethling]

Have ZTR Arch rims with Stan's tape and Ritchey WCS Shield tyres 29 and they keep popping off the rims when I get to about 3 bar, it's bloody scary!

Anyone have any advice??

Hey. I had a similar issue at around 2.5bar. The Arch Inner Bead area is much narrower than other rims. I would suggest you pop the tyres in slowly, ie. pump in to aboput 1.8-2.0 bar and let it rest. It will take some time to pop all the little bits of tyre bead into place. Once you got it all nicely seated, pump to desired pressure........ but 4.5 is a bit high..........lol

Ive got the exact combination. Bought from Naas. Sommer did a rim tape with insulation tape.

 

Popped the tires on. Pumped up to approx 2,5 bar. Removed the valve. Added sealeant through the valve with a syringe. Pumped it up again and voila.
