David, I've used the slime in my motorcycle on a trip to the Smokies, saved the trip, and the tire, drove 90 on the way back, and finished wearing the tire out with it in there. From what I've been able to determine, you shouldn't ever need to patch a tire that has the correct amount of slime in it, and if slime doesn't fill the hole, a patch wouldn't work either, and you will need to replace the tire. They, the guys that use it all the time, say Slime will seal a bigger hole than a patch will fix every time.
