The federal government released new rules stating that cars must have a fuel economy of more than 50 miles per gallon by 2025. That may be a difficulty for some car companies. While there are plenty of ways to extend mileage through new technology and hybrid drives, the easiest and most cost effective way is to just make the car lighter.
It makes sense. It takes more power to move a heavier object down the road than a lighter one. Less power means less gasoline. So how do you make a car lighter? Simple, start taking things out of it. They can't take out the seats, but that spare tire and temporary donut sure taking up space and a little weight. If you add in the weight of the jack and other parts, well, you get my drift.
According to AAA, the spare tire will likely be the first thing to go and add a few more miles per gallon to an already existing automobile. That may not sound like much, but if you're a car maker, you'll do whatever you can to increase mileage without costing any money. This might be a boon to organizations like AAA whose automotive service includes tire changing. You'll just have to buy the tire when they get there.
