I’m new to the Fj scene. I have a 2010 stock fj and I am planning to install a 3 inch lift. I am thinking about 285/70 17 up 285/75 or 295/70 tire. My question is at what tire height and weight do you notice a change in performance that the auto transmission will not stay in overdrive at highway speed. Specifically using cruise at 75+. I live in a fairly rural area( flat land) that allows me to set my cruise at 79 mph and transmission does not downshift out of overdrive even on slight hills. Hope that makes sense.
