spec for 18.4 x 38 tire is 69.1 inch diameter ... there may be very SMALL differences between manufacturers... but that is the SPEC.

Steve, there were inches worth of difference between a firestone or co op tire versus a good year

Good year tires were smaller in comparison to Firestone back in about 1970. Smaller in width and height.
 Come to think about it, there was a thread posted some time ago about a comparison of a couple 18.4 tires... A new BKT to ? ...

When I was in the tire business, it was Titans, but when I left the tire business the bias ply only came in long bar short bar.
