Thanks guys..yeah they we're on ebay..I bought the set of 4 for $275..and since I work at a dealership I can get tires wholesale through our vendor..I can get a set of tires that fit it for like $85 a tire mounted and balanced, or I can get some bigger ones, still cheap. I can get a nice set of nitto tires, 33'' and I'm not sure the width but they'll fit that, for $165 each..I just have to decide if I want to life the truck and get thicker tires, or level the truck so I can take out the boat/jet skis still.
you really have to go at least 305(12.5") wide anything less will start towards a stretch, my stock tires are 32x10.5R17 or 265/70R17 on a 7.5 inch wheel.
so you can get a better idea about sizing, this is a 20x9 dodge wheel with a 305/55R20 terra grappler
you could pick up some Dune Grapplers in 305/55R20 (33x12.5R20), they're a pretty bad ass looking A/T tire and with all the street driving i do i'll probably pick up a set myself before long.
