Can't get new tires to seat on bead

I ordered a pair of new mower tires (15x6.00-6) and cannot get them to seat on the beads and inflate. They arrived pretty squashed flat so now the edges are too close together to catch and inflate. It's almost like they were folded down the center. I've seen them like this before but never this bad.

I have tried the old strap around the circumference method and it won't work as the tire is effectively only about 2" wide because of being squashed flat.

Besides the lighter fluid explosion trick is there a way to get the tires back into normal shape so I can inflate them?

When we get them like that we set them out in the hot afternoon sun and they become a little more pliable, also have some cut 2x4 pieces that we stick between the beads to spread the tire while they cook out there for the real stubborn ones. Its not perfect but it does help.

I take a 5 gallon bucket and cut the bottom off it and make one cut down the side so I just have the side of the bucket. Take that and put it round the tire then put a ratchet strap a round that and ratchet it down till the bead get close enough to seat. I haven't done this on a 15" tire just a 13" so you may need two bucket sides to get it all the way around the tire. Another way is put some tubes in the tires and they will pop right on. Hope you get them on there.

The tool you need is called the bead Cheetah, like this one: http://www2.northerntool.com/auto-repair/tire-equipment/item-145999.htm

The problem is the $400 price tag. I stole the idea, took a holesaw to a portable air tank, mig-welded a 1-1/2" pipe nipple to the tank at the hole, added a valve, and custom, sledge hammer pounded nozzle, and viola! Success. You take a clip on chuck, place it on the valve stem, place the nozzle against the loose bead, open the valve, and whoosh, the tire is up on the bead, and taking air! :cool2::cool2:

Thanks. I actually tried WD-40 and unlike in the numerous online videos of this it wouldn't ignite for whatever reason. Maybe I have bought the idiot proof variety or the % of propellant in it has gone too low. Then I started thinking about how little I know about what any explosion would do and started looking at other alternatives. I certainly wouldn't be putting in enough starter fluid (or anything) to have to worry about flaming chunks of it though.

I did manage to think to set them outside in the sun and used small bottle jacks inside them to try to stretch them back into shape once they heat up. Of course it immediately clouded up and started raining so this tactic may take a few days.

It's a second line mower, no rush. It had tubes in the old tires actually. I thought this would be a good time to replace the worn tires as well. But I may order some tubes eventually if I can't get a fix in a reasonable amount of effort.

put in one onces of regular gas... roll it a bit so the gas spread around.. sit it outside... light li with a candle.. you get instant 10lbs pressure... loll
Don't do this, Alls you'll end up doing is burning down your shop, and removing your nose hairs and eyebrows, if you are lucky. If you are not so lucky, you'll end up looking like nancy peelousy!

recoil rope around the center twisted tight with a screwdriver on small tires works like a strap does on bigger tires. Valve core being out lets more air in faster if you are still trying to seat if the normal way, once the bead is seated put the core back in and air up normally. I have used carb cleaner to seat tires but I alway take the valve stem core out as a pressure relief, not enough pressuse to blow the tire off the rim if no core in the stem.

Bingo, this one is perfect. Try it. maybe even some starting fluid or hell anything flammable for that matter.

I had two 15 x 6 x 6 tires that came almost flat and I tried two ratchet straps, one strap and a rope turning it like I have in the past but no seal, than I tried either and no seal and tried it a few times more with either and nothing except fire. Than I went and got a tube of clear silicon and put a large bead between the tire and rim and it took air ASAP and it squeezed out all the extra silicon which I wiped off. Worked for both in seconds. I have not heard this before but did it work easy. Even if your rim is rusted or what ever, it made its own seal.
