Rear tire won't seat in bead

chas036 · Jul 7, 2018

I had to change a rim on my JD 730 and now I am trying to inflate the tire after I put in a new tube and I can not get it to seat. It seats everywhere but about a 15 inch section . I have soaked it in dish soap and deflated and inflated 3 o 4 times but it just won't seat. The rim is clean and free of rust. Tire is relatively new and not damaged anywhere. It gets close to seating but when I get to 30 psi in the tire, I get nervous and stop. Anyone have any tips that might help?

Have you broken it down completely or just deflated it? Sounds like you need to brake it down and lube it some more. I have also used a lot more than 30 psi. Just stand back away from it. Not recommending it but have done it. About 50-60 is where I would get concerned. Letting the tractor down on it helps as well. Tom

Like Tom said break it back down and relube it. Also dish soap will work but it not as slick as regular bead lubricant. ( Xtra Slik Bead Lube costs around $8 a gallon and you mix it 4-1 so final cost is $2 a gallon. Cheaper than dish soap and slicker. I mix it 2-1 myself) When trying to get it to seat as the tire bead is coming up hit the rim or tire with a large hammer rattling the tire. This will often help get the tire to POP up on the bead. On a large tire like that I would not go much more than 30 PSI. you can blow the tire/bead. There is a lot of Force there. Guys get killed over inflating beads.

My brother used a clip on air chuck and a long hose trying to get a tire on a JD 4020 to seat. He blew out the tire/bead. The concussion blast blew off about 10 foot of his shop's steel siding. Lucky he was standing fifty feet away.

Dad would put it at that 30-35# and then drive it around some. Not pull anything or put a load on it, but just driving around it will stretch and bump and pop itself out. Usually.

If you got kids around, keep their fingers out of that groove.... we all know that, but a reminder for ourselves as much as the kids.....

Mark the spot where it won't seat. Then deflate completely. Then hold down on the other side while putting air in so that spot seats first. Chances are it will seat with plenty of lube.

I've had the same thing happen to me many times over the years. Let the air out pop the bead down all the way around and then lube it up good with wish soap and water mix. Air it back up but as Teddy said hold the bead down 180 degrees out of where it did not pop up at. Plus be 1000% sure you do not get your fingers or toes between the bead and the rim or you can loose a finger

Hey old, I thought that it was many MANY times. This happened to me once with a 20.8x38. My buddy at the tire store went about 20 lbs more than he was supposed to, and then sent me home. I reduced the pressure to around 6 lbs. and drove it around and it slipped out in a little while.

Had that problem many times using liquid lube until we bought a pail of tire mounting lubricant. It is like a sticky grease, that can be mixed with water. We always use it without water and it is 10 times slicker than dish soap. A pail of it would most likely last half a lifetime. Maybe you could talk a local tire shop into selling you some without buying a whole pail. Gemplers sells it, or possibly Napa can get some.

Used to have that problem, I used dish soap too, finally went to NAPA and got some tire lube (think possibly called lubglyde) and have never had a problem since!!

Had a tire that would not seat the bead one time. We just let it set over night with pressure on it. If that doen't do it we run it around or hitch it to a light load like a manure spreader and go spread some. Pops right on then too.

Guys these guys are right, forget dish soap it isn't slick enough. Bead lube from NAPA is far slicker, there are other brands that I used over the years I thought were far slicker than NAPA. Bowes Big Blue is one, Murphys tire mounting paste lube is a good 1. I never thinned it with water, use it straight out of the jug. It is real slick that way. Be sure to put the cap back on, it evaporates.

I have about 50 lbs of Talc, use it liberally DRY

Sure works well...

Tire shop came out to farm and put new tires on tractor and wasn't completely seated. They blew up to 20lbs. and said take it out and run it around field till they seat and after that we dropped them to 12lbs..

Years ago, I was airing up a tractor tire using a clip on nozzle. Trying to seat the bead. The next thing I know, the bead was coming off the rim. When it blew, the force pealed about 8 wooden clap boards off my uncle's farm house. Lots of force.....

Like hd6dtom said tire lube is way slicker than dish soap. Remote air chuck for safety. I use Hercules or Champion tire lube .

Last night I left the tire inflated to 30psi and I had plans to work on it today, but when I went to the barn this morning, it was completely seated. I guess during the night it just popped into place on its own. I had already ordered a gallon of Gemplers mounting lub, but I guess it won't go to waste since I have to change a tire on my JD 60 soon.
