Seating Tire Bead hell!

[Walkers]

Yes it is. Yokohama put a warning not to exceed 40psi if bead isn’t seated right on the side wall. Never heard such a thing before this.

Do you have a pic of this warning?

*edit. I was able to go online and look at the tire sidewall, and sure enough there was the 40psi warning. It makes no sense on a tire with an 80 psi inflation. Maybe they have trouble with the tire bead jumping off the rim with these large diameter tires.
As far as using ether, that is such an uncontrolled process that I am sure the pressure jumps way higher than 40 psi.

For the next time get you some Murphy's tire tire mounting compound, sometimes called Murphy's tire soap. Its the best stuff on the market for stubborn beads.

Maybe aluminum rims and the slap from the tire hitting the rim can fracture the rim?

If you have a few inches of tire that had not popped on it can be several hundred pounds of force hitting the rim.

I didn’t ready everyone’s replies but been in the tire industry for a long time… way too damn long. I have used a heavy duty tie down and wrapped it around the middle of the tire to force the tire walls against the wheel/rim so it will help seat the tire. I am sure you put a bigger hose in the valve to force more air in the tire. sometimes the tire gets hung up on the valve but if the beat seats easily on one side then seat the opposite side first.

I'm sorry it took so long for me to say this.

And lube, lots of lube.

That's what she said.

Whereabouts on the tire were you hammering? [Not to infer that you don't know what to do, but some readers may not, and the tread beatings do sometimes work] My best success is center of the sidewall [bulge] in the center of the unseated bead. I have had to use a real sledge 2-3 times (6-8#'s) but usually my 4# [baby] sledge has done the job, with pressures I'll keep quiet about. The hammering is to effect a rolling of the bead to raise the edge into/over the "safety bead". Glad this worked out easily enough for you as it did, just another trick to keep in your "Bag of Tricks". As a young man with a couple of crappy part time jobs in a recession, most of my [and my brothers] tires were mismatched dumpster "rescues" and at 16-18 years old they didn't last long, so we dis/remounted tires a LOT!

Using the Cheetah and having to put more than 40psi to seat are two different things entirely. You use bead blaster when the tire won't even take air, the quick blast of a large volume of air can stretch the tire out internally to catch the wheel and start inflating.

The 40psi thing....your mileage may vary, but I mount a *lot* of tires, and a lot of performance ones and if I only used 40psi to try to seat, I would still be doing the first tire I ever did. I don't scientifically track it, but I would guess that fewer than 40% of tires I mount seat before 40. Another 40% take between 40-60-ish. The remainder take more. Much more. Much, much more. It is not unheard of for some to take 100psi plus. The 60psi limiter came off the new tire machine before the hunter tech starts his van to leave after installing

All this with proper lube.

Carb cleaner and a cigarette lighter works for me.

Not ether?

Not ether?

I've used carb cleaner on a tractor tire more then once....

I don't keep ether on hand for anything

Plenty of voof in carb cleaner. Actually had to air down a lawnmower tire.

You need more air pressure , we hook up airline to tire until it seats , sometimes takes over 100 psi
Even after a cheetah seats the bead , you still have that little bit that won't quite seat

When replacing the tires on my ‘72 gmc bluebird bus , that had three different styles of split rims on it.
I could not get the last one to seat. Was running 110 psi, hiding behind a brick wall 50 yards away.
Called in a buddy that used to do road service for 18 wheelers.
He just walked up to it and smacked it with a 12# hammer and it popped right into place!

That’s the way it‘s done with split rims, but without using a tire cage, that was a risky move. Split rims can kill.

When we had trouble getting beads to seat at the tire shop I worked at years ago (if they were holding air, the bead just wouldn't pop) is remove the valve core and put the air to it. Sometimes it would take 80-100 psi and it would pop violently. You remove the valve core so the high pressure can release as soon as the bead pops when you remove the air line. Reinsert the valve core and fill to appropriate pressure.

That's how I was always taught to seat beads. The air gets in the tire faster resulting in quicker and more continuous movement. Probably not an issue if you're doing small tires, but on bigger stuff it just makes things easier. I don't see why you would want the core in place while seating beads.

He said that he tried the strap method in his original question.

Not sure if anyone cares...but I mounted 12 tires today. 4 Falken LT285/65R-18 Wildpeak, 4 Michelin Pilot Sport All Season 4 235/30-20 and 265/30-20 and 4 255/60-17 Hankook all season something or another. The falkens all took between 60-70psi to seat. The MIchelins took 70-90 and the floppy Hankooks took 35-50 to seat.

I never put the core in until the tire seats fully. If nothing else, it takes forever to fill up that way, and as noted most tires need the faster flow to start seating.

if its a small gap between the rim and tire roll up a newspaper and push it over the gaps as the tire seats on the rim pull the newspaper out . hope that makes sense as its hard to explain

Well that makes a lot more sense..lol

Be sure you remove the valve stem when you are seating beads so the air goes in faster.

Yes!
Recently had new tires put on my 17" alum wheels at WM.
One tire wouldn't seat up.
The tech had given up. I've worked in this field for over 50yrs, but I didn't want to offer advice.
Another tech came over and showed him how to re seat the tire.
