Bead won't true up on new tire

[oldnortonrider]

I'm in the process of mounting a new Bridgestone tire on the front of my XS. I've got about 14-15 inches of the tire on both sides of the rim, that the bead line won't come above the rim, where the rest of the bead line is around the rest of the tire>making the tire on the wheel a good bit of out of round. Using a new heavy-duty Bridgestone tube with this. This thing has about wore me out for about 2 days.

I did spray it with light soapy water, when mounted; I thought that would be adequate. About the only thing else, I can think of, is to take it back off, and rub everything down with straight liquid dishwashing soap, and inside of rim, too.

I'm sure, somebody out there, has a "few tricks" on this.............

Hey there Carlton,

What I tried before was slightly underinflating it, then bouncing the tire on the ground to try to get the pressure to push the bead further apart. Of course this was with a tubeless tire. How much pressure have you tried to put to it. Sometimes you need to put much more than the required amount in to provide enough pressure to push the bead out, then deflate to the proper pressure once it's seated. DON'T Forget the safety glasses, goggles to protect against any rare explosion!

Is it a tubed type rim, and are the rim locks bolts/nuts loose?? If it's a tubeless rim, why are you using a tube?

I agree with the more air pressure. I seem to remember getting near 90 psi before things worked them selves out, but I didnt try the bouncing trick then.

As a half-wit, I won't put in my two cents, but just a penny. I recommend AGAINST using the dishwashing soap, especially on a front tire. This stuff stays slippery forever. The stuff that the shops use is slippery, but then drys up. The soap, especially when braking, could allow the tire to spin on the rim....and with a tube, would cut the valve stem... instant blow-out!

As for using extra pressure, yes, sometimes it's needed. I, unfortunetly, suffered from what TopcatGR58 referred to as the rare explosion. Deafened for 2 weeks, with resultant significant hearing loss.(tubed tire) Fear drives me from the shop now whenever someone else has to over pressurize these things.

Some parts stores have , and I know that Harbor Freight carries them, those tire air chucks that clamp on to the valve stem, and has a lever to inflate the tire with, thus keeping your fingers out of the rim when over inflating.
Just my penny's worth.

Thank you "TopCat", "Prometheus", and "Rush" >
This is the front wheel; no tire clamps. This is Bridgestone's new 19 inch TW101 (rough tread) > sez tube type on the tire. (?)
$105.00 tire.
Rim sez suitable for tube or tubeless "type".


I did run it up to 100 pounds of pressure; didn't solve the problem. I didn't like the "soap idea", either.

Maybe I oughtta spray it with silicone; it seems to dry out pretty fast, and become "as 'nothing' " .

[oldnortonrider]

I did do the "underflation, and bounced it, and wrestled with it for a good long time". That worked last summer, when I had the same problem with mounting a tire on the rear. Not this time, though.

Thinking about "under-inflating", and running it on a rough dirt road.

First polish the bead on the rim, sometimes these get corroded. At the shop we used an angle grinder with a polishing attachment, but I bet a greenie pad or steel wool will work. Then find an appropriate lube for the bead- we used bead sealant, a sort of liquid rubber. Then take a good ratchet strap- a load binder, we used the stuff that tow trucks use to keep cars from falling off the back end, but a regular load binder would work just as well. Ratchet that sucker down as tight as you can- that will force the tire to expand perpendicular to the rim, not away from it, if you can picture that. Take the valve core out of the valve stem if you haven't already. Pump as much air in there as you can. While pumping air into it thump the tire soundly with a mallet or hammer- has the same purpose as bouncing the tire.

If none of that works take it to a tire shop.

[prometheus578]

yeah, what iron_llama says. Run the strap around the outside circumference of the tire. That's also the trick when inflating the tire and the bead doesn't touch the rim, allowing the air to escape.

Succes, finally >

I had the tire, and the wheel, already on the front. Was quite discouraged, about the idea of having to take "it all apart", and start anew. I let all the air outta the tire > got my hand goo and a small paint brush > took a tire tool and pushed the part of the tire that wasn't bringing the concentric circles up properly, in and away from the rim, to be able to get down inside with lots of goo with the brush. Did it on both sides for about 18 inches. And sprayed down into the area(s) with silicone. I ain't the least bit worried about that Bridgestone monster gripper, turning on the rim.
I then proceeded to give it air. (One of the problems of this, was that I had to use one of those 12 volt mini air pumps.> slow process; and won't work with the valve core outta the valve stem).

Nothing was working, until I got up to about 95 pounds. I kept the pump going>was ready to take it to about 125-135 psi. At about 100 psi, I could see it slowly-slowly-slowly "coming up". I had my helmet and visor on while doing this. I shut the pump off; it was raising about 1mm per 15 minutes. I just left it that way; in about 2 hours it was all up. And then left it set for about 2 more hours with the high pressure, before dropping down to regular pressure.
And, of course, did do all this, with the front end not touching the floor.

What a relief!
It rolls perfectly true.

Hey,

I'm almost afraid to ask:

What is "hand goo"?

[oldnortonrider]

"Hand goo" >
is hand goo soap in a can.

Are you a Harley rider?

Don't wash yer hair with "hand goo".
