Average heights for 215/85-16's run 30.4" tall, and 265/40-22's are 30.3.
Google "tire size calculator" and use one of those to find what size tires would give you the same overall diameter.
Also keep in mind that a given tire size ain't always exactly the same from brand to brand. One manu's tires may be taller, wider, or both than the same size in another brand. BF Goodrich is a good example.
