What are the best tires for efficient fuel consumption in an Audi A2?

I am looking for tires that will help optimize the fuel consumption of my Audi A2. I drive mostly in urban areas and want to reduce my carbon footprint.

Based on my experience, I recommend the Michelin Energy Saver A/S tires. They have a low rolling resistance which can improve fuel efficiency up to 15%. But make sure to also maintain proper tire pressure for maximum efficiency.

I have been using the Bridgestone Ecopia EP422 Plus tires on my A2 and have noticed a significant decrease in my fuel consumption. Plus, they are made with environmentally friendly materials.
