    I just swapped out the rear tire on my DRZ400 and when I put the tire on the bike I noticed that the bead isn't set all the way around. I tried beating it with a sledge hammer, wrapping a cord around the circumference and tightening it like a tourniquet to know avail.

    This is a tube tire by the way...

    Do I have to take the tire and wheel off the bike and start all over?

    Any tricks would be helpful.

    Time to take a break and take the dog to the beach:ear

    you might be able to spray soapy water on the tire and use more psi in the tires to pop the bead then let the air out to the recomended psi.

    I had that problem with the front tire on my DRZ (Scorpion XCMH). Soapy water and all the pressure my compressor could give (100psi) and a few hours and it had taken a seat. The rear jumped right on, though (Trakmaster).

    Really?... at least have the decency to tell the OP that a frag blanket is a necessary part of your idea... :eek1

    Speaking of the OP: most tire seating issues go away if you use bead-lube. Soapy water helps, but the slimy snot that's made for this task makes life a lot easier.

    Most of my tires pop into place at ~25 psi. The really uncoopertive ones pop into place at 60 psi, max.

    I use a bicycle pump. :1drink

    Go out to the auto parts store and pick up one of those stubby brass inflation nozzles. Extract the valve bits and throw them away, they're not needed here. Remove the valve core from your tube, plug the modified inflation nozzle into your air hose (you're gonna lose lots of air) and stuff that on the valve stem. Airflow without the two bits of valve hardware is far greater than it is with. What you're after is rapid inflation, this tool has worked for me the first time, every time on dozens of tires.

    Break the bead again and LUBE. Lotsa lube. I've used straight Dawn dish soap before, but just bought a jug of Ruglyde at NAPA for about $9. Works incredible.
    Set the bike in the sun to soften the tire, mop some lube on the rim and tire and dont be shy about PSI. Look at the tire bead profile and the shape of the rim, you'll see where you want to 'help' the tire slip over the bumps. My 17" SM takes 80 psi sometimes.

    I use maxima chain wax. A really difficult bead will set around 60-80psi max.

    I hold the wheel with both hands so the stuck area of the bead is touching the floor.

    Then I pick it up and strike it on the floor in such a way it pulls the corner of the tread to pull the sidewall away from the rim. It will pop right into place after a few blows.

    I like dish soap as I know it will dry up and be tacky. I don't want to take any chances of a tire slipping on the rim and rotating causing a ripped out valve stem. I have no knowledge of these tire lubes etc. so i don't know what they do.

    But let the air out of the tube, squirk the rim tire area with soapy water and air it up until it pops into place, I've gone as high as 70 psi. Just don't forget to let the air back down to riding pressure.

    I use a mix of Thompson Oil Soap, dish soap and water.

    Which is where my tool is brilliant - without a valve core, the tube deflates near instantly when you remove the air.

    OP back, looks like I'll take the tire/wheel off tomorrow and try re-lubing.

    thanks for all the advice.

    OP back again 2x....

    Couldn't wait till tomorrow went downstairs and really flooded the stuck bead with some Dawn dish washing liquid then pumped it up to 75 psi and bam both sides popped out and I'm good to go. Looking forward to a nice ride tomorrow on my new Pilot Road 3 rear.

    Not bad, 5 hours to change one tire, can't imagine doing it on the side of the road:eek1

    Thanks all for the help.

    you think thats gonna help with a tube in there? Thats what we use to seat a tubeless tire but I don't know if cramming the air in faster is going to help when inflating a tube.

    Put more baby power to talcum powerder or whatever you're using in there, so the tube will slip in the tire easier and hopefully push the tread out instead of the sidewalls out.

    EZman and Perterra, you missed the part pointed out by RVDan that this is for a tubed tire.

    Comment to the original poster-

    You mentioned having mounted the tire on the bike, have you tried riding it and seeing if it will move out on its own?

    You know I was thinking of that and if putting a bunch more psi's into it didn't work I might have been crazy enough to try that.

    Dawn FTW! That or window cleaner concentrate, no water with either.

    If they are really stuck, I'll pump them to around 60psi and walk away. They will usually seat after a couple of hours.

    Op back again,

    Everything is fine, did over 200 miles the last few days and I'm loving my new rear tire:clap

    Over pressuring did the trick.

    I'm getting a big C clamp to pop the bead the next time I do this, gotta be easier than muscling it. Yeeesh 5 hours to change a tire.
