After breaking off 2 of the tire plug tools off in my H2 BFG All-Terrains because the tire is so tough, I found a tire plug tool that takes literally 30 seconds and you don't have to fight to ream the hole out to plug it...

You can get one for $30 all day on Amazon and eBay. Check out the videos on the website. I now have one in my H2 and will probably put one in my other vehicles as well.
