Tire sizes on stock rallye wheels.

The person posting never said if he had disc or drum. The factory disc was a 4 1/2" pattern. The drum was 4".
I have posted the charts for tire sizes, rim widths, tire diameter, load range of the different tires. Do some researching with the charts.
For example the 225/60-15 is the same diameter as the 205/70-14 .
