With the Leaf, and other no-spare tire cars, I would recommend the following tire repair kit... Gloves, tire plugging kit (hole reamer, plug inserting tool, pack of plugs, and rubber cement), several flat screwdrivers and needle nose pliers (to pull out the screw or debris of the flat), and cigarette lighter air compressor. That will permanently repair a flat. It is not as good as the inside patch, but will do for most beginners at tire repair...
Why is inside patch better than plugging method?
I want to hear technical explanation between good and better?
