Bicycle Mechanics - Mounting tires on Sun Rhyno Lites

I am having a hard time mounting tires on these things for my girlfriend's bike. Tires are Geax Easy Riders. I also searched the forums and got the feeling that Rhyno Lites are hard to mount on already and the Geax tires seem a little tighter than any tire I've ever done so I'm not holding my breath. They are so tight, I actually thought they might have been 29r rims and measured. Any good tips to cram 'em in there, though, before I take them to a LBS?

If they can't do it, would getting a folding bead tire (Kevlar, Aramid, etc.) make it easier? I have some Specialized tires with Aramid beads that I didn't even have to use a tire lever for, just two thumbs. Would all folding bead tires be that much easier than a wire bead or are the Specialized ones just different?

Assuming that the I can't do it with your tips, the LBS can't do it (probably not likely) and a folding bead would be better, any suggestions on cheaper (<$25) folding bead 26" X 1.95-2.2" tires non F/R specific more along the lines of XC Race/Slick/Low Knob, etc. with a harder rubber compound. She will probably use it for commuting and the hard packed stuff all around here.

If they haven't changed the rim dimensions in ~10 yrs, I remember those rims being a beeyatch to mount tires onto. The width of the rim makes it very difficult. Keep at it, and have a couple extra tire levers around (maybe get the metal one from Pedro's?)...

I have a pair of Panaracer Fire XC's kevlar bead and can mount them on the Ryno Lites without any tire levers.

My anecdotal experience with Kevlar beaded tires (Vredestein Fortezza Tricomps on American Classic Sprint 350's) was that they were the most difficult tires to mount that I've ever experienced. I almost gave up. I actually quit for a whole day then came back to finish the job. If I ever flat on those tires, I've probably screwed (luckily I don't ride that bike much).

My true feeling though is that it all comes down to rim outside diameter and tire inside diameter and has nothing to do with the bead type. I do like larger diameter rims/tighter tires because they are less likely to allow the tube to slip out during inflation. I have a set of Alex rims that came on my Specialized road bike that are so small in diameter that I need to very, very carefully inflate tires if coming up from low pressure. I've had three tubes slip out and blow up in my face with those rims. Never had that problem with any other wheel set.
