Re: Tire Plugs - safe or not? Posted by Ari [Email] (#2847) [Profile/Gallery] (more from Ari) on Tue, 4 Dec 2007 12:28:49 In Reply to: Tire Plugs - safe or not?, Bill Homer [Profile/Gallery] , Tue, 4 Dec 2007 09:00:28 Members do not see ads below this line. - Help Keep This Site Online - Signup |
I say that a tire plug is fine, under certain conditions:
-The hole/plug are in the tread, and well away from the sidewall.
-You have confidence that the nail didn't hit the sidewall (internally).
-You check tire pressures regularly (don't we all? And floss after every meal?)
-You don't drive at excessive speeds. What the heck does that mean? If you drive the normal 75 mph everybody else does, you should be fine. If you like to see 90 mph on the backside of the speedo needle, don't plug the tire.
The plug itself will be impacted by heat, pressure, and flexing. There is flexing at the middle of the tread, but not as much as on the sidewalls. Heat and pressure are a function of speed, and go up rapidly with speed.
The tire integrity is driven by the belts and the sidewalls. Sidewalls get lots of stress, and anything that compromises their integrity is bad bad bad. A clean hole through a tread belt isn't the end of the world, but could cause shifting later in life. But probably not a catastrophic failure.
