My P85+ is about to enter production (scheduled for delivery June 12th.) I'm having some 11th hour panic attacks about the 21" wheels. I can't seem to get a straight read from the forums/reviews as to whether or not this is a terrible idea for commuting on Bay Area freeways. I commute from Oakland to Palo Alto 2-3 times per week which includes time on 880, Dumbarton Bridge and a short stretch of 101. Are there any other P85+ commuters here from anywhere in CA that have 80+ mile round trip commutes that can speak to their experience with regard to ride quality, tire wear and any other pertinent differences from 19" wheels?
