Mark,

I just bought eight 185/80R-13 white wall tires that closely match the
original 7.00-13 tires.  Delta Brand.  Tires are marked "Made in
China".  Spec sheet link at
<http://www.deltatire.com/catalog/tirelist.asp?tCatID=3>  OD is listed
at 24.5 inches.  Don't know if it's static or rolling diameter.  The
circumference measures 78 inches, inflated tire mounted on stock late
model rims.  Calculated OD = 24.83.  In better spring weather I'll
measure rolling diameter.

You may need to change your mind! :-)
