mpg and balancer tension adjusting

[ned]

as some of you know I have had a hell of a time getting my new Distanzias to seat on the beads of my KLR rims - it has been a huge hassle . . . until now. thanks to all of you who posted some thoughts, ideas, and experiences with similar situations - it helped. so what finally worked? PSI my boys PSI. I knew I had lubed the pigs up enough so that binding wasn't the issue - but they just wouldn't go on. several people said that you may have to use a lot of pressure to get hem to seat. I thought I had enough pressure at 45 PSI (as high as my tire inflator pump would go) but not so. I went out and found a new/used tool / painter compressor at a garage sale that wen't up to 135 PSI. so I relubed the beads and rims, turned on the new compessor and watched the guage. 30, 40, 50, 60 nothing - kept going 70, 80, 90 - about here I could see the bead starting to slide up on the rim and by the time I hit 100 PSI it was finally all the way up and on - whew!! that was the front - the rear actually "popped" at around 85 PSI. so now they're both on and lookin' good. did a test ride of 75 miles and they are some sweet handling tires very stable and confidence inspiring - I highly recommend them for on road smokin' and ocassional gravel roading. they ROCK! so if you go this route be prepared for the difficult install - but enjoy the fruits of your labors. nedinboulder

You want to be _really_ careful with that. I know the tires are rated for 40-50PSI loaded, and that they're under less strain when unloaded and just inflated for mounting -- but a burst tire could kill you. Riding around the block with the bead partly seated probably carries less risk to _you_, though of course more risk of damage to the tube in the tire. I had to run a K761 up to 75PSI to get the bead to seat, and I brought my bike home from the dealership after getting Distanzias mounted when the original tires wore out, only to discover that they'd left the 65PSI bead seating pressure in the tires and let me ride away (!) but 100PSI in a bike tire would really scare me.

I/m Just thinking out loud...would putting a snug, ratcheting tie down strap on the outside of the tire diameter help the bead seating? Tighten the strap in the middle of the tire so that the lower pressure forces the side wall out sooner. The only ringer in the equation...what strength of tie down strap would you need. Some of my straps are 600, 900, and 1200#s. and of course, I did not mark them with a marker and the manufacturer does not either. Having a tie down strap 'shred' under 60-100 psi is not going to be a picnic either if it lets go. Turning off the audio now.... revmaaatin.

I have heard of the tie down strap method before. Give it a try. By the way, it is a good idea to cover the tire or strap, whatever you have, whit heavy blankets while you do this. If something cuts loose, the blankets will absorb most of the impact. I had a tire mounted in a shop. Something did not go right, and the tube slipped out from the bead. When it blew up, (inner tube only), it was louder than a gun shot. Scaped the crap out of me. Jeff A20 [Non-text portions of this message have been removed]

I urge you not to use such high pressures again. There are tire mounting deaths and injuries every year due to such practices. The forces involved in applying such high pressures to an unseated tire are beyond reason. Just my $0.02, Norm [Non-text portions of this message have been removed]

I have to agree with Norm, don't ever go past the tires max pressure. I was in a shop where the new guy was mounting big truck tires. To pop the bead they rolled the tire into a chain link fence cube that was bolted to the floor, then from a distance turn on the air to fill it. The guy went through 7 or 8 tires, and the last one wouldn't pop. He just kept adding pressure and adding pressure till it exploded. The rim shot up and took the whole cube off the floor and dropped across the shop. Granted this is a big truck tire, but you're probably holding the motorcycle tire wile filling it (or at least very close to it). Using such a high pressure can also damage the tire and or inner tube. If the tire doesn't fit it could be a bad tire, or made too small. These things do happen. Next time return it and get a different tire. Darren 2004 KLR-650 A-18

You may want to have your tires x-ray'd for internal damage, or you could call the mfr'er and see what they say, or..................you could just toss them and start over. Fred

I have to agree and disagree. It should be safe to take any motorcycle tire to 50PSI, regardless what's on the sidewall, for purposes of seating the bead. Past that... well... no. Note that it really isn't necessary to fully seat the bead in order to have the tire be safe to ride on. As long as the tire is on the bead and is not pinching the tube, riding will eventually hammer the tire all the way to the outside of the rim. Personally, when I have a tire that isn't seating at 50PSI, I pull out a big-ass rubber mallet and pound the crap out of it until it seats "close enough" (i.e., so it's obvious that it isn't going to pinch a tube, it's on the bead ledge, it's just not all the way to the outside edge of the bead seat). Then I put the air pressure back down to 36 or 32 (whatever the rated max is on the sidewall), and ride it. Invariably when I get back from riding around the block, it's fully seated all around. -E

>I pull out a big-ass rubber mallet and

pound the crap out of it until it seats "close enough" The mallet trick worked for me yesterday when repeated airings to 50 PSI failed to seat the tire. I also made sure there was detergent all the way around the bead on both sides to help the bead move. Stephen --- "E.L. Green" wrote:

Have you ever thrown a motorcycle tire in a fire? The cords (going across and around the tire) are not intertwined with the bands (going around the tire in the bead area). Excessive pressure will significantly expand the tire and push the rubber carcass from the cords and bands. A tire is made up of several layers of rubber and cords (metal and/or fiberglass). As the tire expands the rubber pulls away from the bands and cords, when this happens the tire is weakened and can come apart at speed, or when it gets hot. ned wrote:
