Thanks to everyone who came out! It was a great time and I really enjoyed chatting with all of you. For any I didn't get to talk with I'm very sorry More of you came out then we were expecting!
@JeffC - I think the range hit was a lot more than 5%. I believe the loss is closer to 15-20% with low offset, open spoke wide wheels with performance tires. The PS4S is a very low rolling resistance tire for its class, but we were seeing close to 190wh/km on the highway at speeds around 75mph. My car with the 18" aero's and the OE tires consumes around 150-155wh/km at a similar speed.
