I have a LS GS3038 with 12.4-24 rear tires. The tire pressure goes from 25 to 0 psi in a week. Are the run of the mill tire sealants like "Slime" good for a tractor tire of this size? I assume a gallon per tire might be required.
My "two cents worth" -- with 3 SXS's, 2 4-wheelers, a Kubota
B20 and 5 trailers {3 double axle} as well as two riding mowers and a Gravely Zero -- I am used to flat, leaking tires.
On the trailers {as well as my wife's Suburban and my Yukon XL Denali} I use the red rope plugs I get from an auto parts store {I cut them in half as they are WAY too long} and most of those repairs are usually caused by a screw, bolt etc.
After trying just about every "fix-a-flat" made to man and the pricing getting so high, I decided to invent my own! {I also find that "Green Slime" will rust out the steel wheels over time which meant I'd have to weld wheels where the holes had "rotted through"}
THEN I remembered something I did around 1971 while living in ILL with a 7HP Massey riding mower that would lose traction on my yard which was not level. I used a 50/50 mixture of anti-freeze/water and all but filled the back tires.
Sure helped with traction, no freezing, no rotted wheels.
I moved that mower with me to AR in 1974 and used it for several years mowing 2 acres and then moving small trailers when I started my asphalt sealing business in '79.
I had to break down one wheel once {don't remember why -- and I'm not that old!} -- no rust/corrosion/damage to tire OR wheel!
I sold the Massey in/around 1989 with no tire/wheel issues after 18+ years!
SO -- last year I thought -- most all of these "fix-a-flat" types appeared to be some sticky junk with shredded paper - BUT had to be small enough to be put into the tire through the valve stem.
I took my small chain saw {a circular saw works too but makes smaller material} and cut up a small "pile" of wood.
I mixed anti-freeze/wood shavings {just kept mixing until it got what I liked as far as -- not too runny, but just enough} then break down a tire, install as much as I feel is necessary, air back up and go back to using it.
My only expense is the anti-freeze and time, and to date it has worked flawlessly!!!
I HAD a front tire on the Kubota
B20 that leaked around the bead and in about a week of no use it would be flat!
I had removed the tire, wire wheeled with a 4" Makita the rim {ALL of it -- center, bead, everything -- Green Slim had almost done it's job on that steel wheel!!!} primed/painted and used the black liquid bead sealer tire shops use around the bead of both tire AND rim then remounted it and back to use. I had done that at least three times with little to no luck.
After "cleaning it up AGAIN" I put my "Johnnie's Special Tire Sealant"
) in and have not added air since!
That tractor sat for over a month a while back and when I went to load it I took my portable air tank along {I just knew I would have to air up that tire} and simply put the air tank in the loader bucket and back to the shop it went -- still full of air!
I won't use it in a vehicle as highway speeds may cause vibration -- but did break down a tire on my Yamaha Rhino 660 {same issues as above -- leak/break down/clean/paint/seal/remount} and so far at top speed of 36mph have not felt anything and STILL have not added air -- that tire has stayed at 9psi since!
