MDS is a factor of engine load. Besides that, the tire guy has gotta stop sniffing his glue:

275/60R20= diameter of 33" x circumference of 103.6"
275/65R20= diameter of 34.1" x circumference of 107"

About a 3% difference.

Wonder why you want to go with a shorter any case, you'll be fine. Find another tire store to deal with.
