I have two tires on my truck that have slow leaks, and I planning on putting tire slime in them to seal the leaks. I typically avoid the stuff, as it makes changing a tire a messy ordeal. However, I also don't feel like pulling the tires apart, and grinding the rims, and re-balancing...etc. So I'm wondering if it is just worth it to "slime" all the tires just so the stuff is already in there in the off chance I pick up a nail or rock or something. So do any of you leave slime in your tires as more of an "insurance" policy than as a current repair?
