I put over 12,000 extra miles on a Metzeler tire with a plug. I pick up a # 8 screw X 1/2. The tire had only 3,750 miles on it , still look like new. My first intention was to replace the tire as soon as I got to Sturgis. I always loose about 3 to 5 lbs a day on average if I ride 10 to 12 hrs. It didn't lose any more then that after I had the plug so I just kept riding till It wore out . total mileage was 15,750 That is the advantage of having a Savior250psi onboard tire compressor you can monitor your tire every day. Has far as I am concern if a plug is installed properly and you keep the right tire pressure so your tire don't run hot you have no problem. The most important thing on your Bike is your tires check them ever day. Sspecially when your on a trip 1) You will spot a problem before it gets worst 2) Perhaps save your life. A low tire is a silent killer.
