15 inch rims with 235/75r15 are a good tire size for a 2.3l

I doubt just by changing tire size that you will go down to where you want. Might need a gearing change. I think my 94 is 3.73 and I am considering dropping that 1 step. the 3.73 was good 15 or so years ago when the top speed on hwys were 55 or so. Now that speeds are up to 70-75 or 80 my engine is screaming. It has more than enough torque to start most of the time in 2nd gear, and easily in 1st gear.

i got p235 60r14 and a 2 inch lift in the back i know just tire size wont do much but i was thinking 2 sizes or more in rims might help
