Tom, my point is, you need to check the door edge label to see what was originally specified for your car. It may have 185/R-14's now but I think that is a very wrong size for a wagon. That is not what you should be comparing against. If you found mud in the gas tank would you hunt for equal mud for the next fillup?

For a wagon, so the size should be 185/R-14. Check your door sticker to be sure. My '86 wagon was 185/R-14 (r.i.p.).
If a sedan then 185/70-14.

The overall diameter of the 185/R-14 is considerably larger than the sedan size tires that you now have.

The suggestions I saw in this thread for 195/65-15 and 205/60-15 are closer to 185/R-14's diameter but still less, and enough to cause an error of a few miles per hour at highway speeds. Also less load capacity, though quite serviceable.
205/65-15 will be a near perfect match.

I did make a typo in my first post where I mentioned the wickedbodies tire size calculator. It does calculate "R" as 82. I've settled on "R" = 80 for my own purposes.

I decided on "R" = 80 after finding the 185/R-14 tires listed at tirerack.com. I looked up their dimensions under "specs" and back-calculated the value of "R" from those dimensions. It came out to 80.
