It's good to spin the tire after filling with slime. I get it in a gallon jug. If it doesn't work on first fill, I put a little more in. I always clean out the valve stem before putting the valve back in too.
when I have used it I thought you were supposed to drive around a while to distribute it. that's what I did at least.
Ok, ended up ordering a set of the "Flat Free" tires for it. Pretty neat, they are made of solid soft poly, can hold 500 lbs each. But they are $40 each which is pricey. But at least I should never have to deal with it again! http://www.amazon.com/gp/product/B002VSAO8W/ref=oh_aui_detailpage_o00_s00?ie=UTF8&psc=1
I've seen slime not hold what appeared to be a fairly simple hole on the front of my friends Deere lawn tractor. The slime made putting a tube in that tire a real pita. The tire would not pop off that bead, even with a Chevy cavalier's front wheel and my 240 lb self on the plank. Once I started jumping it finally popped off, allowing us to get a tube in it. Slime is nasty to deal with after its been put in a tire.
I've also herd that before. Worse, tire places (if you ever bring the tire in...), REALLY hate that stuff! They get pee'd off if you tell them you put slime in it... I've been at a counter when a tech was preaching to a customer about the mess it makes....
I've seen an atv tire sling slime all over a machine. It never did fix the leak. And atv tires usually only have 4-11 lbs of air in them
A neighbor I had previously did the expanding foam on his garden tractor. It was a old Deere that weighed a ton and had wheel weights. It worked great for him. He said the trick was you had to let the weight compress the foam and then you added more. He said it took three or four times to get it finished. I also worked with a guy who filled his with quick-crete to give him no flats plus extra weight for pushing snow. He drilled a 2" hole in the top of the tire taken off the tractor and poured it in. Let cure and remount. It sure worked but I always wondered what happened when you wore the tread off. I guess a whole new tire and wheel
It has worked well for me but I found the trick is to fill the tire pressure more than you want it. For example 35psi normal 45 psi after slime. I think it gives it a chance to squeeze through the hole and then I take the pressure back to normal. I also found out the hard way (reading the instructions after I already messed up) that you are supposed to drive it for a while after you fill. Dang fine print!
I have had problems with my little dump cart tires over the years put in new tubes a couple of times. The cart has been living outside for 25 years the tires are cracked all to heck, but it has been working just fine for the last 5 years ever since I put slime tubes in them, these are tubes that come filled with slime and are the best, if you need to take the tire and tube off the not a problem the slime is contained in the tube. As far as the red dust caps on there you just have to break them off and there should be a nut underneath on the axle with a cotter pin. My 2 cents
Thanks guys, but I think it is going to be a much better solution with the Marathon flat free tires. BUT, now that I have a new set of tires, I can always try to fill the old tires with foam, and sell them to YOU guys on ebay!!
