I own a 2011 Big Boss 6x6 and had the dealer install 27" mud lites (their recommended tire) when I purchased it. Well the front tires rub on the steering ball joints and have destroyed the rubber boot on the joint on both sides. Love the machine and where it will take me, but am disappointed that the dealer did not know or care to warn me about these 27" tires. Would have been happy with 26" if they did not rub or some other brand of tire. So if your in the market for this machine think twice about the 27" mud lites. Go with a smaller size or different tire. Oh and watch out for the rear lower A-Arm bolts - they break. Carry spares and a couple of 9/16 wrenches.
