How much pressure is safe when seating beads?

Recommended Posts

meadowfield

I generally have no trouble with fitting tyres, plenty of soap and patience and it all goes well (also having a tyre machine at my dads helps)

 

I've 4 ag tyres on project bendy - two have been fit perfectly on older style rims. Two tyres are on later C series tubeless rims and seating the bead is a pain. The first one was inflated to 40 psi before I went chicken and stopped. As I took the line off and the air rushed out, both bead popped :o how does that work then?

 

On the other I chickened at 45psi, I even tried popping all the bead off and standing on the opposite side,  but it still won't pop on...   :banghead:

 

Tyres are Duro HF255, anyone have any experience with these or pointers to make is simple?

 

cheers

It should say on the tire maximum pressure when seating beads.  Plenty of soap is the key.  :)

I remember dad doing that years ago and sometimes it worked better than others, especially the fire part.  :laughing-rolling:   I think I'll stick to my tire changer.

Lots of soap and 40 psi should do it... Patients!

never tried butane or ether. Icelandic truck trials and ice road truckers swear by the method :D

Starting fluid works well if you cant get the bead to stick to the rim. After that its worthless. A little dab will do you

Small ratchet straps down the center has worked for me, to chicken to try the starter fluid method

I know where there WAS a tire garage that used the ether method on a big truck tire....Notice I said "was", as in it burnt to the ground while trying to seat a tire!

KC- I would imagine someone got funny and put a whole bunch of either in the tire. It only takes a little bit to do it. But if you over do it, yeah, I could see that happening.

I use starting fluid all the time for tires. A little dab will do you. It goes a long way.

had the same problem today.  we put 40 psi into some nanco 23-10.5-12 bar lugs and it wouldn't seat fully.  left them in the sun for two hours, smacked them with a hammer-not too violently-a couple of times, checked them 30 minutes later and they had seated.

Never thought of putting them in the sun.  :text-+1:

I use straight dish soap and a ratchet strap if needed. On the other hand I have chickened out and had my neighbor do the ether trick...

I did leave them in the sun before. Maybe choose to pick a hotter day :D

Are you having troubles getting the tire bead to stick to the rim or getting the bead seated straight on the rim?

He got up to 40lbs of air in it so I thought it was just the seating.  :)

I've put tubes in, so no problem getting air in, just forcing the bead to seat fully. Whilst they look ok with 10-15 psi in, when I lower it to 5-10 then you can see the inside of the rim and it gets grass and dirt trapped!

The either trick is real neat until you blow a tire or rim apart, and something or someone gets damaged or destroyed.

 

to seat the bead to the rim use murphy's oil soap with the vasoline consistancy to fill the gap or use a lubed up innertube between the tire bead and rim, it will pop out when the tire finally seats on the wheel, or use a tire Cheeta tank with a large snout and valve to expand the tire and seat the bead, all much safer and they eliminate the possability of an explosion.

It definately works. You just have to be wise and not use a whole bunch, otherwise, you will start a fire.
