Steel wheels and gass mileage
I currently have an option to do a direct swap of my 15" alloy wheels for a set of 16" steel wheels.
Firstly i'm thinking of investing of new tires so that's not an issue really.
The thing I was wondering about was that steel wheels must be considerably heavier than alloy wheels which would decrease your gas mileage? My car already has a bit of an overheating problem on long climbs so i'd like to keep the engine load as low as possible...
Anyone have any figures for gas mileage after changing from alloy to steel?
Thanks
