Re: Aftermarket Wheels
Often the bigger wheels are much heavier than the stock alloys they replace. Although the new tires are smaller, it doesn't make as much difference because rubber and fabric are relatively lighter.
Weigh one of your old wheel/tire combos (if you still have one, how about the spare as long as it's the same metal and full-size). Then remove and weigh one of the new ones. Even five pounds of increased rotating, unsprung weight per wheel can have a noticeable negative effect on acceleration, braking and fuel economy.
Even though they use incredibly light alloy and even carbon fiber wheels, this is one reason Indy cars still use 15" rims and Formula 1 cars use 13"!
