I have two wheelsets. One is a complete Sun-Ringle Hayes Black Flag wheelset [awesome hubs, very light]. The other is a set with King hubs, and the Black Flag Rims.

Both wheelsets are extremely difficult to get tires on/off the rims. I have to resort to using 10" metal motorcycle dirtbike tire levers to get the tires on/off. Plastic levers snap like twigs. The good/bad thing is, these aren't my wheelsets - they're the wife's! So, that means that I have to deal with these monsters.....I've tried tires from different brands, different sizes, old tires, new tires, worn out tires, and still it's a major struggle to get tires on/off. I've told her "better not get a flat when you're riding without me, cuz you'll be walking out".....

And, I was told by Sun-Ringle Hayes that
"what you are coming across is fairly common among all rim and tire manufacturers as of late. Tolerancing on the Kevlar bead tires has gotten tight, and I mean Continental tight. I've encountered this on near every single high end wheelset and tire combo, though nothing near as severe as the Trek rims of old days. Those were tire lever destroyers! The good news is that while they're a pain to get on new, the tire bead does stretch a bit over time, which makes install and removal all that much easier."
Not really sure what tires he's talking about, but the the beads don't slack out "that" much....

So, MTB'ers - any suggestions for rims that are "easy" to spoon tires onto? Have any of you had this problem of late? I will reluctantly be swapping out the nice Black Flag rims for some alternatives, that will allow my lady to change a flat if I'm not around. So if you want 'em at a good price once I find an alternative, PM me!

It is more likely just those rims.

Sun Rhynolite rims are also notoriously hard to mount tires as well. They have very little of a valley in the center, so pushing the bead to the center does not loosen it like on other rims.

I have DT swiss rims, and no problem with many different tires

try thinner rim tape
I agree: try to install the same tire without rimstrip
If the tire will install easily, then replace the standard rim tape with a single layer of strapping tape, or one layer of Stans yellow tape

Good luck

Putting two tire levers close to each other (~2 inch) and popping the bead off makes it easier. Pop the bead in a small section, remove tire levers. Move the lever over and pop it again. It takes a little finesse to not have the bead fall inside again. The beads are still somewhat flexible, if you can put it in, you can take it out. I like the Pedro's tire lever, it gives more bite. Use your thumb placed near the rim for leverage, it lessens the chance of braking a plastic tire lever. Have the wife practice in the garage.

I'll have to try that out - got nothing to lose! And, it will definitely help to see how much wiggle room is available.

Rims that have a "valley" down the center make it easier. The bead slips into the center, giving the opposite side of the tire some slack. Some new rims that are double-walled have very little or no valley or groove down the center making it much harder.
