I totally agree.
I put new tires and rims on my '71 Jimmy. I had been running 33x12.50x15 meats on 10 x 15 chrome steel rims since I got it in '95. I was getting atrocious gas mileage. Great off road, sure, but I'm rarely there.
So I went down to 235/75/R16 Coopers on 9x16 aluminum rims. Kickouts from a buddy's '99 Suburban. I talked him out of recycling them for the metal.
Night and Day difference. The Jimmy handles fine, especially in town. My speedometer isn't 10 - 12 MPH off, it's within 2 or 3 MPH of GPS indicated groundspeed. I did need 1.25'' spacers. OEM backspace for '67-'72 trucks is 3-5/8'' -- the aluminum rims were 5.''
Looking cool is a side benefit.
