Have never had a pickup without a spare, 99% of the time not hauling much weight so the spare tire plus mounting hardware should help add some weight to the otherwise empty box. Mush ado about nothing here.
I'm doing my best to keep a spare tire. We still have areas with no cell service. I have trouble thinking of leaving my truck on the side of the road waiting for the next guy to come along with a trailer. It's also a race legal way to add a little weight way back there behind the axle.
