Did you take the front back to factory height? That will make a big difference. Actual factory tire was (I think) D-78 which translates to something around 195 -75-14 and looks tiny - actually pathetically undersized on the back.
I think you’re right on that. And the patheticness of the skinny tire. I like what I have in the back right now. It works, but the wheels would have to be changed out to match the front when I get new ones.
