The wife and I have a '14 JKU Sahara that we installed 35x12.50x17 Falken Wilderness Peak At's on with a Rancho 3 inch suspension and RS7000 shocks last April. The only problem related to this set up is when backing up at full lock (I notice it at right lock because I can hear it, assume at left lock the same is happening) the outside of the tread rubs the bottom of the front bumper just enough that you can hear it but I have not noticed any markings yet. I still have very good road handling, no noticable body roll (keep in mind it wasn't a sports car to start with), or any other issues. The dark area just in front of the vehicle where the head light don't light seems a little larger but that is easy to fix by turning on the driving lights. The only complaint I have is the RS7000 are very, very stiff. I had to air down the tires to 35 psi to get some kind of ride comfort. I talked to Rancho and they agreed they are stiff and we should keep the tires at 35 or below. One other thing we noticed recently was tire pressure. It got down to 29 degrees the other night and when I started up the Jeep in the morning the low pressure alarm went nuts. The tire pressure went from 35 down to 29 overnight.
