You could save 5-10 lbs a wheel but you won't likely notice much gain from that on an old truck. If you just want a different style wheel, go for it. If you are trying to save gas, consider how much gas you would have to save to pay for the wheels.

I know it's not the same but I switched from 20" factory alloys and LT tires to 22" aftermarket wheels and AT/MT tires on my Silverado. I expected a decrease in mileage due to the heavier wheels and aggressive tire tread. It made little to no difference.
