OK,who knows a trick to getting new tires to inflate that were squashed flat in

I hate to admit defeat..

Spent a good hour trying to inflate two new 4:00 x 6 " lawn cart or wheelbarrow type tires on my neighbors cart today...with zero success..

These tires came from Walmart--first they told her the ones I had looked up online for her that were $7.77 each on clearance "doesn't show up" when she went to place the order and pay for them..they did find two others the same size,that ended up costing over $25 for the pair & shipping..

What a farce..these tires are stiff as heck and looked like they were left in a hydraulic press for 10 years..you can barely pull the beads apart,and they return to the flattened position instantly..
I tried putting the tires out in the sun with some 8" tubes I had ,inflated,in hopes they would expand the tires back into a normal position...
No dice..after 1/2 hour the tires were hot enough to be uncomfortable to touch but they were still stiff and flat as flapjacks..

I've dealt with tires all my life and darn few defeated me,I know a lot of tricks to get the beads to seat on skinny tires when you put them on wide rims--I tried every trick I know,and none worked..the tread area of these tires come to a point they were flattened so bad,and its like they compressed them while still hot out of the mold,then they cooled that way "permanently"..
So you cant use a tire belt on the tread to help spread the beads open..

The beads on these tires dont look too good either,they had a few hunks of rubber that came off exposing the cords in a few spots..the rims have no "safety bead" like a car tire either,and I don't know how the original tires ever held air,they should have leaked around the bead area..

I had suggested to the neighbor she should have just bought tubes for the old tires--but they were cracking badly and tubes probably wouldn't have lasted long in them..but she uses her lawn tractor cart maybe once a year,they would have lived probably..

I even considered stuffing the tires full of the styrofoam shipping pellets in the box to "expand" them and just leave them in the tire,they wouldn't harm anything..but my neighbor was not too keen on that idea..

She took them home,said she will try taking them to a tire shop and see if they can inflate them..I don't know if their "bead blaster" device will work on such small rims...if they tell her they cant (or wont) do that,she's going to have to return the tires,after waiting almost a week for them to come in..

I wish now I had talked her into going to Harbor Freight--they have tires "close enough" on rims,for $8.99 each,but I wasn't sure if the hubs on those would have the right diameter for the axle or be too wide at the hubs for the axle to poke thru..her old rims are in excellent condition and have grease fittings ,and replacing them "for nothing" if the HF rims fit didn't seem a good idea either..

Anyone fought this battle with squashed tires and won-?--how did you succeed if you did,I'd like to know..

From what you are saying, I would return them and look else where.

Re: OK,who knows a trick to getting new tires to inflate that were squashed flat in

When I saw the heading...who knows a trick?....immediately I thought that Robert would have a solution...not be the one with the problem
I have tried using a wide cargo tie down strap wrapped all the way around the tire and tighten it up...sometimes it works...the video link I am listing...looks crazy...but I have had to resort to using it and it does work...I took my tire out to the middle of the street to do it....if you are skittish, leave yourself a long "wick" to light it

Re: OK,who knows a trick to getting new tires to inflate that were squashed flat in

I am disgusted if this type of junk is what is considered "quality" nowadays..
Crap like this should be outlawed,period..

I have had new 8" rear tractor tires come "flattened" for shipping purposes before ,but they were not as stiff and wide enough so the beads were able to be seated on one side of the rim,then by placing the tire & rim over a pail large enough for just the rim to pass into it and blocking off any lug holes in the rim and the axle hole,you can inflate them fairly easily..

These tires are the same as newer wheelbarrows use,thin like an inner tube with tread..but hard & stiff,and "Nylon" according to the sidewalls---like I said before,the tread area is "pointy" in the center and I tried for quite a while to put a v-belt around the center of the tread so I could twist it tight with a screwdriver and hopefully get the beads to spread open,but it was impossible..

I know all about the starting fluid & a match trick,we had to use that method at the junkyard almost daily to get the loaders punctured tires to inflate after plugging the holes...these tires ,both beads want to go on the same side of the rim !..so all my tricks are useless,and you wont get anywhere using starting fluid--they probably would explode if they did ever seat on the beads using that method too!..

I suppose the tire shop will sell my friend two inner tubes for about the same price as the tires were,they probably wont even want to attempt inflating them..unless they have some magic device that'll work..

Years ago I had a set of three huge O rings sold for this purpose for 13",14" and 15" tires..you placed one between the bead on the tire and the rim after soaping it up good,and that allowed the tire to inflate..but once enough air pressure built up,the o-ring would pop out at 200 mph and usually slap you in the head..
I "lost" them a long time ago,and don't miss them for that reason!..

you could just put tubes in them and be done.

I order mower tires along with tubes from our local tire store and they install for free. Figuring in time and effort it's not costing much more if any compared to ordering the exact same tires from Amazon, etc.

Re: OK,who knows a trick to getting new tires to inflate that were squashed flat in

I had the opposite problem yesterday. Fat tires on skinny rims. Front tires on one of my Fords were beat, I had a couple of decent rear 8 inch tires off a cheapo lawn tractor, so figured what the heck. Had a heck of a time fighting the wider tires on to the skinny rims....but no problem getting them to seat.....lol

As for the Walmart junk. I would take them back.

That was my thought too. I've only had limited experience trying to seat tires. I've been lucky enough to succeed using a ratchet strap cranked down tight around the tire (on the middle of the tread). But I've never had anything nearly as difficult as what you're dealing with. Good luck!

Robert, I've used 2x4 cut to a little longer than the width of the tire. I put a few in on the inside and let them sit in the sun a few days. That helped them regain some of their shape. I then used the ratchet strap method to help push the tire around the rim. It worked but was a PITA! One set of tires was so bad, probably like yours, I couldn't get it. I brought it to my local tire shop and they got it now problem. Magic I tell ya! ha ha

Be careful when you release strap as they can really pop a thumb or finger in the way! The cargo strap has worked for me on several occasions.

Tubes or cargo straps were my first thoughts. Stretching with the 2x4s as mentioned above seem like a good idea.
