Got an 05 660 Rhino. My front 27"x 8" x 12's mud bugs are still good but my rear 27"x10x12"s are Shot. Wanna put something more aggressive on the rear, like a 27x12x12 but a really good mudder. Anyone have experience with aggressive tires like mudzillas or Outlaws? I looked at Executioners today but doesent seem like a very aggresive tread?? Just wondering if there's such a thing as too aggressive or should I stick to Swamp lies, etc???
