As an automotive expert with a focus on performance and efficiency, I can provide you with a detailed analysis of the relationship between tire size, specifically rim size, and fuel economy. The impact of larger rims on gas mileage is a topic that can be quite nuanced and depends on several factors. Let's delve into the intricacies of this subject.
Firstly, it's essential to understand that the size of the tires, and by extension, the rims, can influence the rolling resistance of the vehicle.
Rolling resistance is the force that must be overcome by the engine to move the vehicle when it is rolling without any propulsion other than that required to overcome this force. Larger tires generally have a larger contact patch with the road, which can increase rolling resistance and thus require more energy to maintain a given speed. This can lead to decreased fuel efficiency.
However, there are other factors to consider. For instance, aerodynamics play a significant role in fuel consumption, especially at higher speeds. Larger rims often mean larger, wider tires, which can improve the vehicle's aerodynamic profile if they are designed to do so. This can potentially lead to better gas mileage at high speeds.
Another aspect to consider is weight. Larger rims and tires are typically heavier than their smaller counterparts. The added weight can increase the energy required to move the vehicle, which can negatively impact fuel efficiency. However, if the larger rims are made of lighter materials, such as aluminum or carbon fiber, this effect can be mitigated.
The tire pressure is also a crucial factor. With larger rims, maintaining optimal tire pressure can be more challenging. Under-inflated tires can increase rolling resistance and decrease fuel efficiency. Therefore, it's essential to monitor and maintain the correct tire pressure for the best performance and fuel economy.
Moreover, the type of tires used is also important. High-performance tires, which are often wider and designed for larger rims, may have higher rolling resistance compared to standard or economy tires. Choosing the right tire for your driving conditions and habits can significantly impact fuel economy.
It's also worth noting that the driving style and vehicle speed can influence how tire size affects fuel economy. As mentioned in the reference, larger tires can increase a vehicle's gas mileage if the vehicle is regularly traveling with consistent speeds over 60 miles per hour. This is because at higher speeds, the aerodynamic drag becomes a more significant factor, and the benefits of a better aerodynamic profile from wider tires can outweigh the increased rolling resistance.
Lastly, it's important to consider the engine and transmission of the vehicle. A vehicle with a powerful engine and an efficient transmission can better handle the increased load from larger tires without a significant drop in fuel economy.
In conclusion, whether larger rims lead to better or worse gas mileage is not a straightforward question with a one-size-fits-all answer. It depends on a combination of factors including rolling resistance, aerodynamics, weight, tire pressure, tire type, driving style, vehicle speed, and the vehicle's engine and transmission efficiency. It's always best to consult with a professional or conduct thorough research before making changes to your vehicle that could impact its performance and fuel economy.

When the Volkswagen was equipped with 19 x 8.5 inch tires the fuel economy dropped to only 21.1 MPG -C that's less than a 10% decrease in fuel economy. Larger tires can in fact, increase a vehicle's gas mileage if the vehicle is regularly traveling with consistent speeds over 60 miles per hour.
