I have the 26" bighorns on my RZR and after a few runs on them (they were already used on my RZR when I got it recently) I realized they didn’t hook up as good as they should in a corner. I do mostly desert driving, dry hard pack with sand washes and occasionally dunes which i use paddles for. Before buying new tires I decided I’d groove my bighorns. The front tires didn’t pose any issues for me but the rears would break loose in sweeping turns long before I fe they should have. So I grooved every lug on every tire with the goal of shedding a little rotational weight, making them bite harder, and making the lugs less rigid to help the aired down tires flex better for low speed trail wheeling. I set my grooving iron at 1/4" wide and 5/15" deep and spent a couple hours removing rubber. I won’t say that my way is the best, but I will say I’m glad I did it because they work a lot better now. As for balancing, couldn’t feel anything at all up to 60mph, haven’t gone beyond that lol.
