Are the tires clearances the same between the xA and xB?

I ran on an xA: 16x8, +20, 225/45/16
Worked great for driving. The car was not lowered. The tire would just barely rub the inner fender splash guard only at full steering lock when parking.
The wheel and tire were right at the outer edge of the fender and didn't stick out. Visually it looked like a great fit for the car.
