<font color=blue>NEVER plug a tire on your car</font color=blue>
Bo, this is a topic that
could perhaps generate a lot of controversy./w3tcompact/icons/laugh.gif I was doing tire repairs in my dad's service station when the first new cars with tubeless tires came on the market. Remember the old "hot patches" we used on tubes? We even had customers who bought brand new cars and brought them to us to put tubes in the tires because they didn't trust those newfangled tubeless tires. So I was still fixin' flats when the first "plugs" hit the market, and had some experience with them (black rubber that looked like mushrooms) and yes, centrifugal force at higher speeds would sling them right out of the tire. Of course, since then quite a number of different kinds of "plugs" have come on the market; some better than others. My brothers owned a tire dealership in Alaska for quite a number of years, fixed all flats with plugs unless the customer specified a patch, and said they
never had a single complaint. Now being a bit lazy, I let a local tire repair shop fix most of my flats the last few years, since he only charges me $5 and I've always had him patch the inside; however, he claims the plugs he uses are better. And of course he's closed on Sundays, so I have my own plug kit, and have used it a couple of times; have one plug in the right front tire of my tractor (can't remember how long it's been there) and I have one plug in a rear tire on my pickup that's been there about 3 years.
So . . ., I'm not so sure you're right about NEVER plugging a tire on your car; however, being from the "old school", I, too, still prefer patching from the inside./w3tcompact/icons/wink.gif
