My friend with a normal aspirated 911 went back to 16"s on his ride because he can feel the bigger tires take longer to get rolling.
If you're referring to me I actually picked up a set of 15" Fuchs with 24" tall tires - mainly for the less unsprung weight and gearing differences.

My 15" setup on my NA car doesn't apply too much in this 930 thread. Also a quick fyi - my rear 275/40/17 Azenis measure out to be 25" tall on the 11" wide wheels.
