I use a lot of slime... well, I guess it's both true that I use a lot of slime, and that I own more slime than I use. I own and operate well over a dozen different things with tires on my homestead/farm. Tractors, tillers, multiple types of mowers, large chippers, all the way down to leaf carts... they all get slimed! Slime works for the most part. I do not run slime in anything I drive on the road... not even in trailer tires. People at repair shops hate that stuff with passion. Especially if it's a tire you have put multiple doses of that stuff in over the years. I've had a couple guys tell me, I'll sell you a new tire, or you can take it home, clean it, and bring it back... which way you want to go? I would only put that in a road tire on an emergency basis, and then I would without hesitation. Also be aware it comes in multiple formulations, and they all have a shelf life... the stuff breaks down or congeals and doesn't work properly after a while... so just saying if you have been carrying around a bottle of slime for more than 5 years... you probably need to renew it.
