I did some Grooving and Siping on my wheeling set of 37s to add some more gripping edges for 2018.

I think I did a pretty good job after practicing on an old Mickey Thompson MTZ I had laying around. I had them road-force balanced (like all our tires) and they balanced better with less weight than my brand new set!

Brought some new life to old tires.

AFTER and BEFORE

 

That's pretty groovy man. Far out.

 

I see what you did there!
