regrooving tires with the VA Alstine G-1000

I'm showing how I regroove drive tires with my Van Alstine g1000 regriving tool. it's a very simple process, the tool works great, and dramatically extends the life of the tire. I've been doing it for years with zero tire failures. I know the subject of regrooved tires is very polarizing. I'm not here to start an argument just to show what I do. these tires currently have an average tread depth of 9/32. I cut them to 14/32. ideally I like to wait till they're a little lower, but I had some time today so I wanted to at least do this back axle. in a couple weeks I will rotate the tires and do the other four. thanks for watching
