I found a product called Liquitube that I really like. It does not leave a mess like slim. I have repaired lawnmower,Polaris Rangers, tractor, big truck tires and anything else that goes flat. Instructions say it will repair 3/4" holes in big industrial tires. A gallon with tax is about $100 and I have fixed several small tires and 1 dump truck tire on 1 gallon. I am on my third gallon and haven't had to repeat a repair yet, Joe
