I'm driving a 2500 chevy diesal and pull a double axle trailer with a ztr mower most of the time. There are times where I have 2 mowers or a 65 gallon water tank in the bed. I've used 285 BFG's for the past couple of tire changes. Seems the aggressive tread pattern helps them last longer. I rotate at every oil change(about 5-6k). Any suggestions of good long lasting 285 tires that you've used? This truck is my personal and work truck.
