    I had a similar problem on a different bike recently. I had some sort of sticky goo on the rim from the old tire. Cleaned it using brake cleaning spray. Soap didn't work, so I used WD-40. Cranked the air compressor up to 100 psi and finally got a couple good "plops" from the bead seating. I've heard inflating the tire and leaving in the sun to bake for a while will soften the rubber and cause the rim and air to expand enough to seat the bead. Some may say this is bad advice but it worked for me. Good Luck.

    I just had the same problem yesterday on my 990. I lubed the bead area with a water dawn soap mixture that provided enough lube to allow the tire to seat. It took about 60psi before it snapped on to the rim. It was a real bitch to get it to seat. Be patient and don't let it get the best of you.

    The bead popped with about 60psi and i hammered away in one spot for about 10 minutes but it just aint right.Issm sure even though it says tubeless on the carcass it should still work?.

    I experienced the same thing this last time I swapped tires and use the new K60. I let the air completely out and broke the bead then re-inflated it. -pax

    I swapped tires out the other day & my neighbor loaned me a bucket of tire lube & a brush. It looked like aged beef tallow, but it worked far better than soap.

    Highly recommended.

    My 140 k60 never popped, leading to another thread on the ever-useful OC. It is seated evenly and has not given me problems in several thousand miles. I blamed the no-pop on there being as much pressurized air in the bead area as in the tube, due to the vast quantities of soap, water windex mixture I threw at it, so it just eased itself in there. I had to unseat it and reseat it to prove it was ok. Don't know if my theory is bunk but it made me sleep easier, especially after reading other inmates had no pop as well.
    Sounds like yours is not right though, not if it looks all goofy. There should be a line in the rubber that is even with the rim all the way round on both sides.
    Old experience on a KLR I was trying to seat with a plastic hand pump on a hot day in Greece...it took a short ride to get it to pop in.

    I didn't have any problems with 150 0r 140 Heidenau. With stock wheel was a little harder, and it went very easy on narrow excel rim from Woody. I just did 140 this morning.

    I always use Ru-Glide -- http://www.amazon.com/AGS-RG18-Gal-Ruglyde-Lubricant/dp/B000CIJUGK

    I got a gallon 8 years ago at NAPA store.

    BTW, I think that 140 is better handling tire that 150, dont know about longevity yet. It's more round. Also it's much easier to break the bid than 150.
    150 was gone at 5k.

    Let the air out and hit the beads with silicon spray. I won't mount a tire without it. You will be glad you used silicone when you go to remove it as well. It works so much better than soap but the moral is that you need lube. Armor all works great as well.

    Last time I had that trouble with mine another inmate told me to air it up to about 50psi and take it for a ride.

    I had serious doubts about this but it worked within a 1/4 mile.

    All the above^^^^^^ Do yourselves a favor, get some tire paste for mounting new tires. It makes the bead seating easy and if far better for your wheels, and won't premote corrosion like regular dishwashing soap.

    I hate Heidenau tires... :kboom
    I'm pretty good at mounting tires, but these things are just too tight.
    I've bent tire irons, broken beads, and scratched the hell out of my rims...
    I won't use them any more.

    Had a hell of a fight with my K60 Scout rear too. Front went on easy, but the rear costed sweat, blood, and a good scratch on the rim.

    Mounting tires is an art and maybe the most physically demanding of all art forms. I was taught back in the 70s by Leroy Winters. Leroy was National Enduro champion, an ISDT rider and my boss at a Honda dealership. Everybody who worked at Leroy’s changed tires his way or got another job. He taught me how to change tires fast and without pinching the tube, so I could do so in Enduro. I’ve changed hundreds of tire since then, many in Enduros (and a few hare-scrambles) and even more for other riders out on the trail.

    Everyone here has given some good advice. Soapy water is NOT good, because it’s not slick enough and because too much of it stays inside the tire which later corrodes the spoke nipples, valve steam and even the inside of the aluminum wheel. WD40 is wonderful for mounting tires. It’s slick enough and later dries and leaving the tire sticky so it doesn’t slip on the rim, and it’s good for the spokes, valve steam and wheel.

    After the tire is mounted (I assume it has a tube in it) you need to inflate it some, maybe 40lbs and with the valve core removed from the steam. Then release all the air. Do this a few time to make sure the tube is not caught under the tire somewhere. Then with the wheel on the floor (on top of a towel) place you knees on the tire—and your weight—where the tire was popping out on the rim the most. Force the tire in there, this will make the other side (where the tire will not pop out) come out. Look in there, where it won’t pop out and make sure the tube is not caught between the tire and wheel. With your knees pressing down on the tire as described above, inflate the tire (again without the valve core installed). You may have to do this a few time and add more WD40 in the problem area. Once it pops out, you can install the valve core quickly before it deflates.

    I wouldn't ride it and hope it will pop out, unless frustration leaves you with no other choice. If the tube [is] caught between the tire and wheel, you be riding back with a flat.

    Good luck!

    Thanks for mentioning that, Q-- I've been considering them, but I have all the problems I need changing tires.

    I'll stick with the Mefo's, I guess.

    Just copied and pasted your post. I have a little motorcycle notes file for when I get a bike. Just on the basics like this.
