Rally gravel tire grooving with a Van Alstine G-1000 tire groover

In this video we show the basics of tire grooving with a Van Alstine G-1000 tire groover on a stage rally gravel tire (we are using an MRF tire but we show cutting /recut / grooving recommendations from Hoosier, Michelin and Pirelli).
Tire grooving can be really useful to improve grip in wet/muddy conditions.
