Im thinking about getting some steel wheels for my truck, because theyre so much cheaper than other wheels. Im not sure yet though. How much of a difference is it going to make if I have steel or alluminum wheels as far as performance? how much heavier is a steel wheel going to be? I dont want my wheels to hurt my mileage and performance but I dont think they could weigh that much more but I dont know? Has anybody ran both to see the difference?
