• Yes, it will. Our EZ Spare 175/70R20 is designed to fit Audi Q8 e-tron models with factory wheel sizes ranging from 18-inch up to 22-inch—including your 21-inch wheels.
• That’s because our Audi Q8 e-tron spare tire is engineered to match the overall rolling diameter, not the rim size. The key for compatibility is the total tire height (diameter), which ensures safe, temporary use during an emergency—even if your original wheels are larger in diameter.
• So whether your Audi Q8 e-tron came with 18″, 20″, 21″, or even 22″ wheels, our compact spare tire will fit and perform as intended.

The overall diameter and width of our spare tire are listed on our website. It’s important tomeasure your vehicle’s wheel well before purchasingto ensure that our spare tire fits.We cannot guarantee it will fit your specific wheel well, as insufficient data is available on popular websites.
Since many newer vehicles do not have wheel wells, we provide a premium spare wheel carrying bag with handles for storing the EZ Spare in your vehicle’s trunk area.
