    +1. Are you guys leaving the valve stem in there or something??? Never had a problem with any motorcycle tire. ATV tires on the other hand can be a real PIA!

    If you do your tires at home it will be easier when your out on a ride or carry AAA card. :D

    On my first tire change, I ground off about 8" of the safety beads on each side. I can now pop the tire off with my hand, like a dirt bike. I did it opposite the valve stem (I think) so I could remember where to push. No chance this is ever going to come off by running it flat.

    Popping it with the side stand works good too.

    I wouldn't be so sure about that statement. This happened with full safety beads on the rear wheel of my 950 Adventure:

    I think tires are easier to change on the big Adventure rims. Getting the bead of the tire past the safety bead is the trickiest part. I use a slightly different technique than some have mentioned. I lever 1/3 or more of the bead area toward the safety bead as far as I can and then lever the center of that section over the safety bead. Other than that, the drop center is HUGE on those rims and there is no bead lock to deal with, so the rest is cake! I have bicycle tires that are harder to change! :huh

    Ok, I'll change my statement to: cutting the bead won't increase the chance of a flat tire coming off.

    I've noticed those MEFO's have a looser bead than the Scorps and pop on/off easier. Are they tube type only?

    So did you manage to twist the tree out, instead of breaking the bead?!:rofl

    Sure enough! The Mefo on my 990 says "Tubetype" on the side. I have changed a few of those and also pulled the stock Scorpion off the 990. I don't recall any of them being particularly difficult.

    Any other tire than the K60 and the side stand works fine. I had the bike basically balanced on the side stand on the bead and that sucker wasn't budging. I was getting worried about busting the side stand.

    No but it did crumble the side of the brick!! :huh
