1974 Scamp What Wheel/tire size question...15x8 b/s?

Thats my bad, I didnt read it correctly.

So if I want to squeeze a 8 inch rim on the back, I should go 235 60, or 50.
Or...just put 7's with 4.5 bs all the way around... and put 225 or 210 on the front if I have to have the staggered look...

Thanks again for the insight

That's why I wound up with (4) 225/60-15 all around with (4) 15x7 wheels with 4.50 backspacing.

If you must stagger it, yes the 235/60 should work with those 15x7 wheels on the back. You could do this:
215/65-15 front, 26.0 diameter, 8.46 section
235/60-15 rear, 26.1 diameter, 9.25 section

Another alternative for the front would be 215/60-15 (25.15 diameter, 8.46 section) but don't go any smaller than that for diameter)
