It not a scam ( well not
It not a scam ( well not completely). They are liable if it fails and there's a wreck. I just took my car to a repair shop yesterday and they refused to plug it. They said I need to pay $50 for a used tire. I have fairly new Michelin tires. The puncture is off center, an inch from the side. It's still on the bottom. So, I went home and pulled the nail out and just put a plug in it Now, it's fine. I have another car that I plugged and the plug is actually closer to the side of the tire. It's still holding after 3 years. It depends on how much money you have and how how fast do you drive. In today's inflationary market, you got to save some money. The $5 repair kit has lasted 3 years and has plugged 3 cars so far.
