skid Jackson -> Tire mounting (8/2/2008 2:08:38 PM)

I took the irc off the rear wheel and put the older michelin back on it. The mich has better grip and I figured I could use the irc on my trailbike to see what that is like. anyway The mich has been sitting around for a year or more. It went on fine but I can't get it to inflate to seal the beads. I tried my little compressor and then tried one down at the gas station.  no go. The beads have "closed in" from sitting around. I'm thinking I might leave it out in the hot sun in the driveway to soften/heat it up. might help it expand into place. was also going to bring it down to my dads place which has a real compressor and see if the extra umph got it on. anyone got any tips .. other than bring it to a dealer ..which is a distinct possiblity!!



Mike -> RE: Tire mounting (8/2/2008 3:05:10 PM)

Wrap a tie down around the complete circumference of the tire right in the middle. Pull it tight, this should spread the beads out against the rim. Now use a high volume compressor to inflate it.



44Dwarf -> RE: Tire mounting (8/2/2008 4:16:10 PM)

You did take the valve core out right? this will allow full flow in to the ire to POP it up on to the beads.



skid Jackson -> RE: Tire mounting (8/2/2008 5:07:39 PM)

Thanks for the sugestions i'll give both a try!
Forgot to add that the tire is tubeless, although it sounds like you guys got that figured out



BobIT490 -> RE: Tire mounting (8/3/2008 10:44:04 AM)

Yamaha "Tire Mount Lube", take out the valve core, use a real compressor. Yamaha's lube is slipperier then an former NH Gas Gas dealer. Yamaha discontinued it due to "environmental" issues. I've got a couple of cans of the stuff.  Stop by and I'll give your beads a few "squirts".[;)]

Take the valve stem out and pop a couple of firecrackers in there, that works wonders for me!

This wouldn,t be the same Donkey Punch from Micro WW2 would it.

I always put a tube in the tire, inflate to the bead is about 4" or so wide and leave it for about a week. Remove tube, put the tire on and put the air to it. Works every time. OH! don't forget to put a little dish soap and water around the bead.



44Dwarf -> RE: Tire mounting (8/4/2008 10:26:47 AM)

If it alum rim DO NOT USE DISH SOAP!
I know we all used it for years but ever take a tire off and find white crud all over the bead seat?
Soup is not PH balanced and it stays in the bead seat and rotts the bead seat.
Most "tire lubes" are PH balanced and are safe.

44  I ??? your statement.
            I have worked in a tire store for about 3 yrs. ( yrs back ) I have seen the crud you are talking about, only with ALUM rims. WE always used rubberlube to mount tires. Can rember useing a wire brush to clean the white stuff of the rim. IMO, I think it is just the ALUM rim not what you use.



blackduc98 -> RE: Tire mounting (8/4/2008 11:57:22 AM)

Skid, I read that a "tire beader" gizmo makes mounting the tubeless rear tire much easier.
I bought one of these, but haven't had a chance to use it yet:

Regarding tire mounting lube: I've used dish soap before, and just like 44drawf said, there was a lot of white crud on the rim. Don't know if it proves cause-and-effect. Recently I switched to talcum powder instead of dish soap. Not sure if this will improve things, but I figured it was worth a try.



skid Jackson -> RE: Tire mounting (8/4/2008 10:10:13 PM)

I put  a strap to it, pulled the valve core and filled up the 10 gallon tank on my dads compressor to 100psi and let 'er rip. took a couple of tries but most of the bead set. I had about 1/4 of the tire that would not pop up onto the bead though. It would hold air, but let it leak at the same time. let air in and out a few times, bounced it like a basket ball, hit it with a rubber mallet ... finally let all the air out and put some wd 40 on the section of rim that would not seat. Put some monster air to it and it finally popped on. Little nerve wracking wondering if the tire might blow a bead!!



44Dwarf -> RE: Tire mounting (8/5/2008 7:12:54 AM)

Some rims are just made of crap recycled alum cans, thats for sure.
My info came from one of the industry trade magazines you get when I had my tiny shop.
They had a test write up that used several tire mount lubes and several brands of soap.
KLubes cause the least amount of crud.  Tire beads move around more then most think. 
Ever pull bark out of the bead area? I have....dam trees.

44-- SO what I get out of your last post, nothing is good, they all make crud. Every lube and soap.

I guess my statement " I think it is the ALUM rim, not what you use. " is pritty accurate, but I have never seen the crud on my ALUM pots and pans after washing with dish soap. ?? A lot of times they have soaked over night.
You are right the tire does move, and I think that has more to do with the white stuff then any thing IMO.
Thanks for that info.
   



44Dwarf -> RE: Tire mounting (8/5/2008 11:51:41 AM)

The thing with your alum pots are the soup is washed off not left there and pounded in to the suface each time you move the pot.

All I'm saying is use the right stuff it don't cost alot of $$ and can save the rim for the next guy down the road.

bmac -> RE: Tire mounting (8/5/2008 12:03:17 PM)

Ya the Pot thing was just a little joke.

But what can we use it all makes crud, per that write up you got ??
I have had t/bikes as long as 8 yrs, never had a problem with the rims.
I think someone said to use baby powder, maybe that is better.

If I'd seen this thread earlier, I would have mentioned that you should always wear safety glasses when seating beads. I forget who but someone injured an eye several years ago. Something nailed his eye at tremendous speed. Keep your fingers as far away as possible too.

Seating beads on tubless rims has always concerened me. As bmac can attest, they put truck tires in cages to contain stuff if something lets go when seating beads. Things can get real nasty. I like to attach a truck style air filler that clips onto the valve stem. The clip-on fitting is on one end of a hose and there's a lever valve to turn on the air at the other end. This allows you to step back and fill without having to touch the rim.

Seating the bead is the only drawback to tubless though.  I'm not sure how much today's riders appreciate tubless rims/tires. Tube type rears are a pain in the butt...  You don't worry about tubless tires moving a bit on the rims but it'll tear out valve stems on tube types. Some lubes get tacky after a while but I never did trust them to hold the tire in place - especially in wet riding conditions where tires occasionally get levered off the rim by rocks and such. Water will just reactivate them. Talcum powder was a real no-no.

I had pretty good luck with denatured alcohol (on the rim Bill...). It's slippery when wet but leaves no residue when dry. I wouldn't recemmend alcohol for tubless rims though - makes it a bear to break the bead when dismounting the tire.



bmac -> RE: Tire mounting (8/6/2008 3:40:38 PM)

Steve you are right, I have seen the aftermath of a truck lock ring go threw a wall.

My 1977 TY I had till 1985, changed many tires and never saw any rot, from soap, just that white stuff.

You know that weird tearing sound you heard? It's the cord ripping from 100 PSI. Every tire has a maximum inflate pressure on the side for this very reason. I strongly recommend you not go over the stated limit.

This is what I'd call a "It won't go in, get a bigger hammer"  style of doing things.
