They will rub on full lock without a level kit like Candy08 said . They stated on the add that combo is 35" , someone correct me if Im wrong but 295/70/18 is 34" . 34s will clear with a level kit but if they are 35" you may get some rub on full lock. Also your MPG reading and speedo will be off a little and there's not a programer for 2011 so you wont be able to adjust your guages for the tire size increase.
