Knuckledeep do plugs hold well on a gash that size? Around the farm I don't care as much, but I hate to stands myself on the side of a mountain and have to call someone. That sounds more expensive than replacing them now.
I've plugged four wheeler tires before, but something this heavy I have no experience with.
Hardlyworkin: exactly! 430 something not and I still have tits on them in places! The turf mode really let's you get the most out of them (comparing to the RZR I had whose bighorns were half gone by now)
