Trying to seat a tubeless Shinko on a Borraani rim with a tube and just can't get it. I did get one side with lots of soapy water and a rubber mallet but the other side just won't fully seat. I've tried a rubber mallet, wood drift with hammer, high pressure (50psi) and low (25psi), always with lots of lube and one 12 inch section just won't seat. I've also deflated and reinflated several times but the same section won't go. The inside of the rim is clean. In the past, a little "coaxing" with the rubber mallet worked fine and fast.

Try something better than soapy water. I usually use a light coat of straight dish soap. Other will have their favorite lube. I would go higher than 50 if necessary, but I'm not saying you should.

I've put Shinkos on my Jackal. No soapy water, just baby powder and about 60 psi with bouncing. Then lowered the psi to normal.

With the Shinko 712 I some times have a problem with the circular part of the tube's valve stem interfering with the bead. May have to push the valve stem in a bit before you inflate to make sure it gets on the inside of the bead. Other than that it sounds like you are doing the right things to get it to go.

Yep, never had any problem with mounting Shinkos, on Borannis at least. I do use Ru-Glyde during the tire change.

Mounted a pair of Avon Roadriders onto V50 Monza rims yesterday - rear was easy peasy, front wanted to be a PITA. Liberal Ru-Glyde didn't work, spritzed it down with regular old Windex and it popped out slowly.

I'm a big proponent of Ru-glide, it's the slickest stuff I've found and formulated not to eat up the tire or rim. Both beads of the Michelin PR 3 I mounted the other day popped into place at 25 PSI. Some tires are tougher; I thumb my nose at the lawyers and go to 60 PSI if I have to on a tough tire.

As tires develop, the hard part is starting to be getting any pressure into the tire at all without it just blowing out through 1/2" wide gaps between the bead and tire. I use a 120 psi compressor, with the valve stem taken out, and a ratchet strap cinched down, and sometimes that doesn't work and I have to hang my head in shame and take it to the shop who has a $350 bead-seater and let them do it .... Maybe I'll buy the $180 version, but that would pay for 9 whole tire changes ... hmmmm....

Dusty, I did try bouncing it, maybe I should try off the roof?? Acogoff, it's not the valve stem, that area is fully seated. Charlie, I'll try some Windex and/or soap as Triple Jim suggested and more air pressure. Keep the suggestions coming just in case. Whew, my arms are tired from pounding and my knee is killing me from a bad bounce of the mallet, yes, it could have been worse.....Jack.

Lannis, just read your post and will try Ru-glide and remove the valve stem if the above doesn't work.

I'm trying to recover from imagining the scenario of taking a big swing at the sidewall with a 2-pound rubber hammer and it bouncing wrong and hitting me in the ..... worse. The humiliation of "I did this to MYSELF" would make the pain more intense, if that were possible .....

If you employ the high altitude method , please get someone to film the incident Just make sure to let go

Dusty

It's okay, my dog likes to play catch, hope he waits till after the first bounce.

We had a problem with bead seating of a Michelin PR3 which hasd arrived from strapped tightly to another tire. Finally after trying everything we knew we tried a heat gun and warmed the tire (very warm to touch) section that refused to seat. It worked- apparently softening the tire bead and allowing it to resume as-molded shape.

Not an issue if you have inner tubes...

jbell · « **Reply #11 on:** June 16, 2015, 04:20:17 PM »

Gentlemen, be seated. Finally, a bit more air pressure, up to 55 psi, I was skeeered to go any higher from the creaky noises the wheel was making and a whole lot of liquid Palmolive dish soap and I was able to coax the bead to seat. I now have a lemon scented rear tire. This was rapidly approaching a "Hey fellas, watch this" scenario, so thanks for the advice and encouragement. A little polishing on the rim (oops) and I can balance this sucker. I will look for Ru-glide next time I'm at the bike shop or auto parts store.......Jack.

I know I have gone to 70, maybe as much as 110. Not saying you should, just a data point.

I'm not sure if it's an exclusive NAPA-supplied thing or not, but NAPA is the only place round here that carries it.

I have had good luck putting the tube in the tire airing it up and setting out in the sun for a couple of hours to expand the bead prior to mounting it on the rim. I am also a fan of RUGlide.

Ru-Glyde/RuGlyde/Ruglyde can be bought on Amazon and at Pep-Boys as well as NAPA.

Yep.

Ru-Glyde/RuGlyde/Ruglyde. The last time I mounted a new rear Shinko, was the first time I used, honest to goodness genuine tire mounting lubricant. Before, it was always a little bit of struggle, and the Shinkos will make you swear and sweat.

With the RuGlyde, it was as easy as watching a youtube video. ( well maybe not, but close.)

Tire lube and don't be too afraid of a goodly amount of air pressure.

I've been up around 80 lbs on well lubed tires more times than I want to admit. This is not a suggestion, just what I've done.

BigDave in PA · « **Reply #18 on:** June 17, 2015, 08:19:29 AM »

If your bike has a center stand, go ahead and install the wheel. While on the center stand start the bike, put the transmission in high gear and engage the clutch. Next open the throttle and rev it 'till the rev limiter kicks in. Centrifugal force should seat the bead. ;)

Just kidding.

There's aways this method.

Yep, and be sure to have that lit cigarette in your teeth when spraying starting fluid all over the place :)

Groover · « **Reply #21 on:** June 17, 2015, 12:26:43 PM »

The guy whom installed mine had to put nearly 100lbs pressure to make the front seat. Pirelli Sport Demons on Mags. The rear popped pretty easily. The person installing was a professional tire installer too, and the tire was in the safety cage while doing that however.

Good luck.

Remove the valve core before pressurizing and use the NAPA bead sealant.

Triple Jim · « **Reply #23 on:** June 17, 2015, 05:42:49 PM »

The OP is using tubes.

cwiseman · « **Reply #24 on:** June 17, 2015, 08:12:14 PM »

Starting fluid isn't nearly as dangerous as one might think. Just spray it in there, add some air to stir it up and light, usually a whoomp noise and she's seated.
In my younger years a bit of gas and a few kicks to a atv tire would gets ya fixed back up but that was more violent than starting fluid and usually lit by throwing a burning stick at it as opposed to a lighter.

Linseed oil and lots of air pressure. 50 PSI is not much.

Triple Jim · « **Reply #26 on:** June 17, 2015, 10:05:49 PM »

Linseed oil, huh? Interesting. It's slippery, but then oxidizes and gets sticky, then almost hard. I might need to try that. I assume you mean boiled linseed oil, right?

Boiled. I dunno. I'll have to check the can to see. Gotta find it as I have not used it in awhile. I always carried a bit on road trips but never had the misfortune of needing it on the road!!

Triple Jim · « **Reply #28 on:** June 18, 2015, 12:58:55 PM »

Not a big deal whether it's boiled or not. The boiled version just dries in a couple weeks instead of a couple months. It may not matter at all for a motorcycle tire. Now I'm looking forward to my next tire change so I can try it.

One does wonder how a boy from Chicago even knows what linseed (boiled or not) oil is

Dusty

Story time. I moved to the deep south: Warm Springs Ga. where Roosevelt had his polio hospital. It took quite a few years to understand their dialect.
One patient always brought fresh boiled peanuts when in season. The first time I was offered "bald peanuts" I was thinking WTF is a bald peanut. I had no idea they were offering me "boiled" peanuts. I kept say what? and they kept saying you want some "bald" peanuts. And we went around like that for 5 minutes and I said I do not understand what a bald peanut is. Once we finally got the dialect part down I found I loved fresh boiled peanuts. It was hilarious to go around and around until we figured out their pronunciation of "boiled" peanuts sounded like "bald" peanuts to me. Of course coming from Chicago to the deep south these kind of dialect problems happened over and over and over. Sometimes they would get pissed at me cause I kept saying huh what are you saying. When they got pissed at me I always had a comeback and boy then they really got pissed off.
I said tell me this.... do you ever have any trouble understanding me? And they would say no we can always understand you. So my comeback was they where the ones having trouble speaking English correctly. Next thing I knew I had someone chasing me wanting a piece of my hide.
