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.
I meant to say they wouldn't fit without a leveling kit. You should check out the regional section of the forum, alot of guys from LI. Cheeck out the Bilsteins for leveling, not only did it improve the look but they improved the ride tremendosly.
