How Much Do Tires Affect Fuel Consumption?

[StBeckett]

Tires affect fuel consumption in the following ways: 1. The impact of tire width on fuel consumption: Wider tires have a larger contact area with the ground, resulting in greater friction resistance, which naturally leads to higher fuel consumption. Narrower tires, on the other hand, result in lower fuel consumption, a factor largely determined by inherent design. 2. The influence of tire tread patterns on fuel consumption: Off-road tires with larger tread patterns are suitable for rough terrains like gravel but consume the most fuel. Performance tires, which generally emphasize grip, have wider treads and offer better handling, resulting in moderate fuel consumption. Comfort tires, with their fine and smooth tread patterns, provide the lowest fuel consumption. 3. The effect of toe and camber angles on fuel consumption: Poor wheel alignment (incorrect toe or camber angles) increases friction between the tires and the ground, not only damaging the tires but also raising fuel consumption. 4. The role of tire pressure in fuel consumption: Insufficient tire pressure increases the tire's contact area with the ground, leading to higher friction. This not only causes wear on the tire shoulders but also increases fuel consumption.
