What’s more, we know under-inflated tires have a negative effect on fuel economy. This should mean less rolling resistance and increased mileage.

In theory, that makes sense: With more inflation pressure, the tire bulges in the center of the tread and creates a smaller, skinnier contact patch with the road. We’ve heard folks claim mileage gains by running their tire pressure above the manufacturer’s recommendations. Sometimes, despite what GM's recent track record suggests, carmakers do know what they're doing and the recommended settings and levels do provide the best results. According to 's testing, the fuel consumption difference between driving with over-inflated tires and tires at the recommended pressure is negligible. Even if you are lucky and avoid a collision, it would take a lifetime (which could very well be short if you're riding on bald and bulbous tires) for your fuel savings to negate the cost of four new tires. This all adds up to a large risk in costly accidents and injuries. What's worse is that the decreased contact with the road increases stopping distances and limits handling capabilities.
However, overinflated tires will wear out quickly and irregularly, causing you to need early replacements at a cost of about $50 to $100 per tire. Over inflated tires will have less friction with the road, which lessens the effort the engine exerts to keep the car rolling, providing slight gas savings. The Theory: Rounder tires roll easier, creating less work for the engine and therefore, better MPG.
