hello

I could fit the tire on sun rim with some difficulties but the real big problem is there that tire could not fit on the rim properly like on sides following lines of the tire . instead the tire is not "round" like as the rim.

The rim which is UST model makes this thing worse. I did tried soap too, unfortunately I didn't have air compressor instead I have hand pump because I use usual tube..

any tips, options? maybe use without tube? what do I need to get that damn thing to work?

thanks for replies

Keep pumping until the bead pops on. With XC tires and rims I often need to pump to 60 or 70 psi before it pops on properly.
