I've got a new rear tire mounted on my supermoto and I can't get the last bit of beat to seat. I've tried soapy water, windex, wd40, I've broken the tire completely back down and reinstalled it, I've put pressure on the side opposite of the trouble spot, I've gotten the trouble spot to move around the tire, I've hit it with a hammer, I've bounced the shit out of it, I've tried a ratchet strap, I took the inner tube out and reinstalled it thinking maybe it wasn't sitting in the tire correctly and probably about a dozen times I've deflated and reinflated to nearly 90psi. I leave for a race at vir tomorrow, what else can I do to try and get this thing to give me the last little pop
Sounds like you covered the basics already, so I will add this: Try tire warmers before mounting the tire. I only had to resort to this once, and that was for a heavy cruiser tire, but it worked.
+1. Tire warmer. Soap the f out of the tire and rim again. Strap it around the outside of the whole tire but make sure it's not too tight or it won't seat.
If you do your own tire mounting...go to NAPA and get some Ruglyde...best lubricant for tires. I bought a gallon years ago, still have 95% of it. A few drops lubes it up, within a half hour the stuff is gone, no water, no residue.
Try blasting air in it soaped up with the core OUT of the stem.... Once beaded pull the core and apply more air
This might be too late, but put a ratchet strap around the tire with it deflated, placing the ratchet at the spot where the bead won't seat. Tighten up the strap until the tire just starts to collapse, then air it up. Also with the epic amounts of soapy water.
soapy water is terrible tire lube. it always seem to get not-slippery right when u really need it. get some real stuff. if this was a tubeless tire, id suggest keep going w/ the pressure. my record is 145psi on a run-flat auto tire. but not sure about a tubed tire. either way, once u get over the max pressure, i hope u have it on a long hose and are standing back
Lol, been there, done that. A word of warning - that tire inflates a little more quickly with the valve stem out and the beads seat simultaneously (and fast as shit).
Yep, when I turned wrenches on cars for a living that is how I always had to do the wider, super low profile tires. I always did them all that way, pull core, hit with air until bead pops(always makes you jump), pull hose, put in core. Adjust air. Real stuff does work better than soap, but soap does work when there is nothing else. Some wheels have to be careful about the soap having a degreaser eating away at the tires on that bead and also causing some weird crap to go on at the bead/rim area, causing odd corrosion there as well. More of a bigger problem with wheel corrosion on cars that have steel wheels, but have seen it on the powder coated alum car wheels
On my little cbr 125 I have to manipulate the tire by hand to get it to pop. I found some side pressure where it wont seat and like 50psi goes a long way. 90psi routinely does jack shit to the front tire even with a tire warmer. 140+ .... youve got to be fucking kidding me! nope.. nope. nope. thats scary shit. i dont have a cage in my garage to try that
