Yeah, no lapping or any sort of track days. I do push the limits on the on ramps though, LOL. I have plugged a tread block and in between blocks and not had any sort of problem. You have to remember the are self vulcanizing(SP) plugs, which means they bond internally to the rubber in the tire. When you install them about 3/4 of the plug is pushed through the tire and then pulled back on the inside. Creating a mushroom effect on the inside of the tire. After a couple weeks you can't even see the repair from the outside.
