Sagging tire, can it be saved? - Steel Soldiers::Military Vehicles Supersite

Guys,
I searched for this but couldn't find anything... I have a 9.00-20 wheel and tire that came off the spare tire carrier of a six-ton shop trailer. The tire has lots of tread left and no weathering or sun damage that I can see, but it is deformed from hanging at zero PSI on the spare tire mount for some time and sagging under its own weight.

Before I go to the trouble of disassembling the tire and wheel and putting in a new inner tube and flap, I was wondering, can this tire be saved? Will it be permanentally deformed? Is it safe to use a tire such as this?

I will try to take a picture and post it, but maybe my description of the tire is good enough.

Thanks,
Matt

Its worth a try! It should be OK with new air.

Is it still deformed after you put air in it? If it is, it will be that way with a new inner tube. Even if you get it aired back up it wouldn't be the same size as a tire next to on a rear axle and would wear that tire out faster too. I wouldn't use it on the front axle either and check the date code. Wayne

Maybe try nitrogen

As long as it gets back to orginal shape, I would try it..

Try airing it up, if it leaks it will probably be heard there as you are airing. If so a tube is in order, so dismoint it and install the tube and flap, removing all debree inside the tire caseing and re-assemble, air and there you have a decent spare like papercu says it may not be the same diameter or it might still be..... you will know soon enough. Another thing you can do is look up BUILD DATES FOR TIRES on the web to find out how old this tire is and use it acordingly.

I would put a new tube and flap in it, remount it, then install it on the truck and take it out for a run in an attempt to straighten it back out. Bias/nylon ply tires are more prone to settle like you're describing than radials.

I drove a truck 500 miles with one of the duals flat, the tire was in good shape, but oddly formed after the journey, it sat for months when I got it home, and I changed the tube, it was fine.

Thanks everyone. I'll try to air up the tire. Even if it leaks as is, if I can get it to 50 PSI I should be able to see if it returns to its original shape.

If the tire remains deformed, I won't use it. I don't want to be penny wise and pound foolish.

Thanks,
Matt

Be very sure that the locking ring is fully seated prior to putting any air in the tire!

If the tire is without any air pressure, it is possible for the ring to become unseated. If so, the ring/rim/tire assembly will come apart catastrophically when air pressure is applied.

Is that wheel/tire the same as a Deuce? If so, and you decide not to use the deformed one, come up to the shop and I'll give you one.

I think it will be fine, though.
