My car tire had a dry-wall screw in it. I bought a cheap tire plug repair kit at the local Pep Boys for about $12. It was hard to use because I had to apply a lot of force to the plastic handle and it was painful. A month later I found another screw in my tire. I left the screw in until I ordered a heavy duty tire plug repair kit on Amazon. The all metal handles were a pleasure to use. Since then I've used it a couple more times and the tires have not started leaking again Read the rest
