1973 Dart Swinger Owners + 17" Rims

Using the site above, it looks like the max size 17" tire/wheel combo is as follows...

Front: 17X8 rims w/ up to 4.5 b.s. and 225/45-17 tires
Rear: 17X9 rims w/ up to 5.3 b.s. and 235/45-17 tires

I assume these measurements are allowances based on stock ride height.
