I just got my new 5100 installed on all 4. I also went with Toyo Open County A/T.
My stock size tire was 265/65/17
My toyo are 265/70/17
I installed my front 5100 at 2.5". The rear was just an install of shocks nothing else.
At stock my front end sat at 19 inches off the ground. Now my truck sits at 22.5 off the ground. that is a total of 3.5" My tires added just over an 1 inch additional.
