I haven't heard of that - I will look for it when I'm at Walmart this week - thanks! Yeah, its the hedge trees that are my nemesis as well. They drop branches with those long thorns so the tires don't stand a chance.@HEChicken have you tried that goo stuff you put in tires to stop leaks? It's called Slime & you can get it at WalMart or probably hardware stores as well. We have so many hedge trees here that our lawnmower tires look like a sieve. We use that stuff in the tires & it really helps. Unless the hole is big & then you would have to plug it first. It sure has saved us numerous times. Of course there comes a point some time when you have to give up & get a new tire.
