I have had a tire on my F150 with a slow leak for several months. It might 2-3 weeks to lose 10# or a couple of times it lost 20# over night....Making me crazy. I did the soapy water a couple of times with no results. On the overnight loss, my son wondered if the truck had been parked with the leak in touch with the ground and just right to leak more. Sure enough, a very close inspection of that revealed a tiny nail about .020 in diameter and when pushed a bit sideways would leak. Since the hole was so small, getting a plug into it would be a chore, so I decided to put a wood screw into the hole instead. I picked a small screw that is commonly used in door hinges, kinda fat but only about 3/4 inch long. Carefully zipped it in with a drill and just slightly buried the head.....soapy water and it didn't leak. Its got about 500 miles and has lost no air. Went surfing the web to see if I had a marketable bright idea and discover the SCREW PLUG has already been invented, You can buy a pack of 40 for 5-10 bucks from Walmart!!!
Who woulda thought..... I will sooner or later replace my screw with a plug.....but, it was a novel idea.
