I just pulled the trigger on some larger rims and tires to help level the ride on my '76
Sovereign. Another major reason for the switch was because I was sick of replacing increasingly expensive vintage hubcaps once or twice a year.
Only problem is finding nicer looking chrome lug bolts, they seem to be nonexistent in 1/2" thread pitch.
Here's a couple before and after shots to show the change in ride height. Hopefully much less dragging the rear end everywhere I go.
