Tire Groover

Today I learned how to re-groove tires. There were no spare tires for Mike to teach me with so he volunteered his shoe. The tire groover has a sharp blade that gets hot enough to melt/cut through the rubber. It goes a lot faster than I expected. To use the groover you push the blade into the rubber, as pressure is applied it makes the electrical contact to heat the blade. The blade glides smoothly through the rubber, then it’s done. Simple, now to try it on a tire.  Thanks for the quick lesson Mike. I should note that this is used for solid rubber tires, not the ones with air in them.
