Interesting that I just came in from plugging a hole in my Tesla's tire.
First off, I'm forty miles from Costco. I bought an air pump years ago so I don't have to drive somewhere on a low tire and ruin the sidewalls doing it. One tire showed about seven pounds low yesterday, so I backed the car out this morning into the drive and got a bowl of hot, very soapy water and washed the treads. I DO NOT remove the wheel from the car.
Sure enough, a little pile of tiny bubbles started stacking up in one area. I could feel the screw with my fingers. I summoned the car to back up a couple feet so I could lay down on a blanket and see the hole, then got out my plug kit and pulled the screw and shoved a plug (very sticky piece of rope) into it. Aired the tire back up and spread soap suds again and there were no new bubbles. Fixed.... By a 74 year old guy in cancer remission who's been sick for two weeks again. So it can't be hard.
Saved a bunch of time. Took maybe 30 minutes. And now I find Costco would plug it for $11, so I know what I'm worth!
