How tire pressure affects fuel consumption and tire wear.

Model: (Various brands) Various
Part: Tires

The video introduces us to a very important topic: how tire pressure affects fuel consumption and the tire itself. Low pressure increases rolling resistance, so the engine has to work harder to maintain speed, increasing consumption by 5-10%; high pressure slightly reduces resistance but the effect on consumption is minimal compared to the safety risks and wear. The correct pressure indicated by the manufacturer optimizes fuel consumption. As a result of tire wear, low pressure causes uneven wear, especially on the edges, because the center lifts, reducing the tire's lifespan by 25%; conversely, high pressure accelerates wear in the center of the tread, with a greater risk of impacts, as the rubber is stiffer. It goes without saying that the pressure indicated by the manufacturer is optimal for the proper wear of the tread.
