Intertube tire bead not lining up evenly

[coreyspare]

I got my tire on the rim, put my innertube in, and popped the other half of the tire on the rim. However when i fill the tire up with air the tire sits on the rim unevenly. there is a ring around the outside of the tire where the rim should come up to it, however there is always a part of the tire that is "sucked"into the rim. the line is just below the rim, and it is uneven. Ive inflated and deflated the tire about 20 times, i put soapy water along the bead, i greased it up with vaseline, ive stepped on the tire to pop the bead out and reseat it. all ive managed to do is move the part of the bead that sits too far below the rim around. Any help would be greatly appriciated.

You probably need more air pressure to pop the bead on.

 

[habsdoc]

Yup, crank up the air pressure to seat the tire bead and then adjust pressure for riding.

How much pressure are you using? As others have already mentioned, you probably need more.

With the lubrication you have mentioned (please avoid Vaseline), you should be seating at no more than 40 psi, but a short burst above that would not hurt.

Do you have the valve stem in too? When I inflate to set the bead I give it a blast with out the valve stem and the once both sides are set I immediately deflate... Once completely deflated install the valve stem and inflate to riding pressure.

My 2 cents. I've been up to 80 psi before to see a tire make bead. On a tubeless radial though...

 

[coreyspare]

i pumped it up to 55 psi, do i need more?

With lubrication AND A CLEAN RIM, you should have seated with 55 psi.

Do you have the valve stem in too? When I inflate to set the bead I give it a blast with out the valve stem and the once both sides are set I immediately deflate... Once completely deflated install the valve stem and inflate to riding pressure.

I need to find an inflation tool that will allow that. The one I have relies on the valve stem to push a core in the middle of the inflator that then allows air flow. No valve stem, no air flow.

The tire is lubed and the rim isn't the cleanest thing, but I wouldn't call it dirty. I had it up to 55psi, bounced it hit it with a hammer, I even went as far as putting the tire on the ground and stepping on one half and my wife stepped in the other half and filled it up with air, but it's still on there uneven.

I've had this myself, especially putting a tubeless tire on a rim that is not tubeless and therefore has an innertube. The innertube may be an explanation or, it is that the tubeless tire is just a very tight fit. There are differences in how different brands go on different rims, (it seems Shinkos can be tight on suzuki 19'' wheel rims? etc.)..anyways. keep trying. It'll go on eventually.

It can be worth the $$ take the wheel to a mc shop if it's a ggod shop, they've seen a lot more tire fitments than you ever will.

otherwise maybe I can add to the tips above,(high pressure, no valve-I made a hose without any valves except a single handle-type valve(the proper name escapes me ) Once seated, you deflate and put the tire valve back in,pump up, as Jedz is saying.

"proper" beading lubricant. It really is better than any (hand-soap!) soapy water I could stir up...smearing the innertube as well might help if it doesn't work when just applied at the lowest bead but clean all the other crap out first and let it all dry before using a little bit of lubricant....

I finally got it. I mounted the tire to the bike, filled it up to about 70 ish psi, my tire gauge only goes to 60 psi so the 70 is a guess. I then rode the bike around the circular driveway about 10-12 times, and checked it was all even.

+1 on using proper lubricant.
Warming up the tire a bit can help too. A spacer heater that has a fan can really help with difficult tires.

 

[Gorminrider]

heyy! good news coreyspare! 70# yikes! (but so many gauges are inaccurate - I might have 1 that is good... My example, like yours-innertube in tubeless- need what appeared to be 55# that I ran from an old car tire pumped up ( for lack of proper air tank) and blown direct as I described but the gauge was crapola so I'll never really know)

Ps: the electric heater is something I'll take note of.Hadn't thought of cold rubber!

I've had the same issues trying to seat the bead straight, using dish soap and over inflating the tire trying to get it to seat, it's all about the lube and yes a warm tire helps a lot.

Maybe it's time to get some tire install lube, it's relatively inexpensive and works so much better than soapy water.

my 2 pennies.

I had rear pirelli sport demon do this exact thing to me. Tried 2diferent sizes. Same problem. Switched to Avon, problem solved. Was using wire wheels

My old timer dealer told me he can't count the times it's taken 80#. I've come close to that as well. Safe? I don't know, but he's old and so am I, we're still here, LOL.

A standard road bicycle tire of the skinny racer type runs 115 psi and weighs in at a whopping 220 grams. I prefer the slightly fatter 25mm wide ones and run 95 psi. So I find it almost humorous to hear concerns of catastrophic failure of rather massively more sturdy structures at lesser pressures.

I guess it's cultural. But the only way to know for sure would be destructive testing.

good point! ^ a la bicyclettes I'll keep this in mind next time...""if a bicycle can do this so can I!" mind you, there's all the air of a balloon in a bicycle tire..."la pop!" Not so sure about the KABOOM! of a larger tire...
