Welcome.
Yes, the Recon sits a bit higher than most other JKs. That being said, disconnected and fully stuffed off-road, you could still get into your inner fenders a bit with the 285/70/17s unless you add a small bumpstop extension or went with flat fenders (flat fenders on a Recon can have you running 35s). My previous JKU had a 2" lift in the front and still made decent contact with the inner fender when fully flexed and disconnected with 285/75/16s (same size as the 285/70/17s).
