My problem isn't really getting the tire onto the rim, it's getting the bead to seat properly. Countless times I've fought with them. Lubing, inflating, deflating, partially inflating and pulling the tread side to side, lol.
A lot of times it goes on the first try, but sometimes!?!

My set of sun rhino lites(sp) are the toughest to get tires onto, and it's a good thing really. I'd rather they not come off on that particular bike.,,,,BD
