find the additive inverse of -9 on the 12 hour clock?
A plug should only be considered a temporary repair. It may fail, or there may be structural damage to the tire's carcass. If you want to install a plug yourself, go for it. But no dealership will do it, for safety and liability reasons. Any Service Department that doesn't follow best practices at all times will get screwed in Court at some point.
Seems to me you could put a tube in your tubeless tire. But if not, I would like to hear the reason. PS.Being a Harley you wont be worrying about speed ratings.
Other have covered most of reasons. Plugs are not best practice but can get you home- just like fix a flat. A patch on inside of tire is a much better repair, can get a seasons run out of bad puncture on new tire. Putting a tube in a 'tubeless tire and wheel' has also been done, especially if wheel has damage rim , slow leak issues or a road repair- it is hard to get a tubeless' tire to grip rim without a band or a 100 pounds pressure air tank and tire jig-- but a simple inner tube inside can be pumped up with a hand pump and patched tire with nail removed will then seat on rim bead, get you home and around town for a week- that turns into the rest of season riding to rallies until tread is worn down to replace tire.
It sounds such as you obtain that top. by using fact that -9 on a 12-hour clock (probable) ability that the hour hand is grew to become around anti-clockwise from 12, it places the hour hand at 3 o'clock.
+9 itself. In fact in 12 hour clock there is no -9. Additive inverse of 9 is 3. In fact, Additive inverse of x is 12-x.
