You misunderstood what I said. Your post made it seem like you thought the inside tread (or inner sidewall) of the tire would be on the outside if you crossed the rotation which isn't true..... the inside of the tire stays on the inside regardless of where you mount it on the vehicle. So having whitewall mounted "inside" doesn't even matter, you'll never see.
Sure, the direction of rotation changes, but the inner tread is still on the inside of the vehicle.
