It is.  It is a perfect circle on a frictionless plane.

But if it's not, use the minor radius, then calculations can be done for the 
worst case (large vehicle, smallest angle turn).  Besides, no-one is going to 
go out with a tape measure.  It's going to be eyeballed, or estimated from an 
aerial photo.

Best wishes,
