Stepdaughter's Tiguan had a slow leak in LR tire. Pulled it off, soaped it down, nail about 25% across face of tread. Removed nail, dressed hole, fiber plug with rubber cement installed. Wait an hour. Inflate and cut off excess. Been plugging all manner of tires for 5 decades. I have had a few that failed/leaked after repair that required a tire shop patch. I have some spoons but am too lazy for steel belted passenger car tires to patch myself. Anyone else plug tires? Or is the consensus is, it is too dangerous? I would gladly patch if someone gives me a pneumatic tire machine. Comments for or against?
