Seemingly simple question but my google-fu is failing me and the site search here is just crashing so.. I was checking my tire pressure today and found a nice nail in the center of the rear. It was a good 1/2 to 1/3 inch in, but was at a severe angle rather than straight down, so it's hard to say how deep it actually was. I yanked it out and have been checking the pressure every few hours - it hasn't changed. Now what? Do I need to plug the hole with something (what?)? Do I need to take it to a dealer and replace/patch the tire? edit: the obvious answer is 'if it ain't broke don't fix it'. thank you for the reassurance, all. Maybe I can get a bedtime story too? I was not mechanically inclined at all before my first bike, and I've learned the hard way to ask when I'm not sure about something motorcycle related.
