Leaking Tires !
What a pain they can be.
While I have sworn a lot at the 'slime' when I have to clean it up, I do use it. And, it does dry out, and the stuff I used to use would be rejuvenated by an ounce or two of antifreeze [ethylene glycol] added to the tire.
The off road dune buggy crowd swears by the stuff, and I have to agree, it does work. I had several sets of very expensive and THIN paddle tires on my sand rigs.. they leak, a fact of life, and a tube is counter productive, because it just makes them heavy. So everyone uses a sealant. It's a mess when a tire gets shredded and you have to do a clean up.
I have kept a tire alive for years with all kinds of bandaids.. like the front tire on a 30hp Diesel 4x4 JD, with loader.. LOL..
The front tires take a beating on a tractor with a loader...what carries the weight when the loader is in use? yep, the front tires..
I bought this used tractor with abused front tires.. they must be kept inflated.. one tire had a bad pinch on the sidewall, and the cords were cut, i could see the inner layer of rubber.
I just did NOT want to pay for tires at that time.. and I have tire repair materials.. I put a double layer of heavy tire patches on the inside of the side wall, then put in a tube.. it lasted for 4 years.. !! Until I over loaded the loader,
and drove over something that pinched the same spot, and ripped the hole larger.. the double layer of patches started to 'oozze' out of the growing hole...
I finally broke down and bought two tires off the 'net. had them in 3 days, and I was able to replace them quickly with the usual hand bead breaker, this thing is invaluable, it looks like a giant nut cracker. Look it up on Harbor Freight. I use it several times a year.
Anyway, valve stems, shrader valves and rims are the most common leak points with tubeless tires. I often am able to get another few years from a leaker by breaking the bead, cutting the valve stem off from inside, installing a new one, cleaning the bead and reinflating..
OH,, the ether / fire/ explosion thing... well, that scares the crap out of me.. but I have used it a few times..
I'm sure glad I did NOT know about it when I was 20 yrs old.. I was out on the dunes.. very drunk, and blew a sand tire off the 16 inch WIDE rim. and it was tubeless.. and then staggering drunk, tried with the help of my [also drunk] buddies to get the tire to seat on the rim with a hand pump..
So, picture this: three guys trying to pull on the tire to get the bead agains the rim, one idiot [ ME ] on the hand tire pump, pumping like crazy, all standing on soft sand, and falling over, sand flying everywhere.. LOL.. we gave up until the next morning..
If we'd known about using ether, I'm sure that tire would have been destroyed that night..
or someone injured.
It would have been hilarious to have a video of that episode.. but that was in the days of 8mm film cameras..
