Do 20 inch wheels fit a 2001 Jaguar XJ8?

No, 20-inch wheels do not typically fit a 2001 Jaguar XJ8 without modifications. The standard wheel size for this model is usually 16 to 18 inches, and fitting larger wheels may require changes to the suspension, wheel well, or the use of low-profile tires to avoid clearance issues. Always consult with a professional or refer to specific fitment guides to ensure compatibility.
