Tire regrooving is a great way to extend the life of your tires. Especially if you have large deep tread tires that can take a regrooving well.
This home DIYer goes ahead and uses a chainsaw rather than a standard re-grooving tool. With the tools costing between $1-400 and it’s probably likeyou you have a chainsaw anyway, I can see this as a no-brainer.
If you own a shop or plan to do a number of sets of tires, maybe it’s tiime to kick in and buy a real pro tire groover.
