In this video we review and discuss wheel weight and if it makes a difference? The comparison in the video is between 18" vs 15" and what the weight difference is between the two. The wheels compared are 18" VW GTI Replica aluminum wheels vs 15" standard steel wheels with plastic hubcaps. This also affects MPG due to increased drag and friction from larger (wider) tires in contact with the road surface as well as increased wind resistance. Not only this but starting, stopping, and maintaining motion requires more energy with heavier mass wheels.
