Quoted: I used it to repair a tire on my car (nail hole in the tread) and then proceeded to get another 20,000 miles of service horribly unbalanced abuse out of that tire. |
Fixed.
After you stop driving for a while, where do you think that puddle of goo settles (and eventually hardens)? You can't keep driving forever - Eventually, it'll puddle on one side of the tire when you park the vehicle overnight.
Do yourself a favor - Get a $5 tire plugging kit (the kind that has a plug insertion tool, a hole reamer and half a dozen plugs) along with a $4 can of tire cement. Pull the nail out of the tire, ream the hole, put a plug on end of the insertion tool before dipping it in the can of cement, and then insert the wet plug into the hole just far enough to have just a little bit of plug sticking out. Trim the excess plug with a razor blade, air the tire up to recommended pressure, and you're done. It's easy, cheap, quick, and you don't need to add 5 pounds of wheel balancing weights afterwards.
