Hello I registered as a member today. Thank you for the excellent information available here...prior to purchasing my 2007 Prius package 6 I read and was greatly assisted by many of the postings at this forum. After 40 days of ownership my experience from new mexico: a 5 day aweek, 68 mile round trip commute, all highway ( 70 mph speed limit) other than 10 miles of 25-50mph small town roadways with one stoplight. For all intents and purposes I do not use the car on the weekends.... average miles per gallon 47.5 my commute includes elevation changes, varying temperatures, and headwinds both ways more often than not. I keep a toshiba libretto 100ct laptop in the vehicle for long term record keeping. To this point i have added, a computer display sunscreen--and touchscreen protector---side window shade-mouldings and have a front end bra in route. Future plans including replacing standard wheels (ring-covers) with something more efficent--- Froley
Welcome to PriusChat, Froley! Do a Search for aerodynamic wheel cover and you may see some racing covers you like.
Froley, welcome. You can pick up a couple mpg by inflating your tires to 42/40 but you'll feel more bumps.
