Hey im considering buying the mickey thompson baja atz radial slt tires. does anyone have these on their x? Im not sure if they make them in a 265/70-16 size (same as stock) but i was wondering how much worse gas mileage would i get with a 265/75-16? I would rather stay same size as stock. any other suggestions on all terrain tires?...besides the cookie cutter bfg's.
