Ok, how does this sound:
225/60r15 tires on 15*7 wheels in the rear.
BF Goodrich 2 1/4” Whitewall
215/70r14 tires on 14*6 wheels in the front.
BF Goodrich 2 1/4” Whitewall
The rear tires would be 25.6” diameter and the front would be 25.9” diameter. Difference of 6 revolutions per mile.
They’d be visually very similar looking from the side, roughly same total diameter, same size whitewall, but would be different widths. Hoping this can give me much better grip and help improve handling compared to the very thin 195mm wide tires I’ve got on all four corners currently.
