First off, put the 285/70s on. I have them on my ‘09 without a lift on stock wheels. I used 1.25” spacers to get the look I wanted.
By the wheel specs you provided you will not need spacers.
Second, check your speedo with a GPS to tell how far off you are.
Mine was off 3mph before the tire change(58 on speedo was 55). Now it is spot on.
Third, I have 3.21 gears. I calibrated my throttle(key on engine off, slowly press pedal to the floor and back. This calibrates pedal to tps through the computer.)
On steep hills if it feels sluggish I shut off the over drive.
Otherwise it isn’t too noticeable.
