Not sure I would trust going 148mph in a cherokee lol. Also both my winter and summer tires are only T rated so max speed is 118mph. I have gone 135 in a previous car but it was a sports car and felt pretty solid at that kind of speed. And I went around 125 in an Audi Q2 last year in Germany on the Autobahn. That was pretty scary in that suv, it did not feel safe.
