I've been using the wheel more this weekend and I'd like to make the question in a different way, as I think I was not explaining my doubt correctly before.
It seems the issue I was talking about is regarding the "resistance" that the wheel offers when it's moved. These are the settings that Logitech profiler offers:
That resistance is controlled by the section 'Centering Spring'. If I don't tick it, then the wheel doesn't have a deadzone regarding the steering movement (as it's registered fine by the windows controller settings) but the steering is really smooth (as in, not resistance at all - you can turn the wheel with a single finger and it won't center back once it's turned).
By enabling this section and adjusting the 'Centering Spring Strength' (eg, from 100% to 150%), one can get a lot of resistance (which I like) so that you have to hold the wheel tight and use quite a lot of strength when turning it and it will center by itself when released.
The problem I was finding with this setup is that once the 'Centering Spring' setting is enabled, then such a Resistance doesn't start until une turns around 15 degrees each side, ie, there's around a 30 degrees area in the middle of the wheel without any resistance at all, and then one starts feeling the setting we've choosen.
But, is there a way to configure this wheel so that the Resistance is offered in the complete area?
Or if not, do you know any other Force Feedback wheel where the Resistance can be felt even in the middle section, when the wheel is centered, so that one cannot move the wheel around 15 degrees each side with a single finger before the Resistance starts to be felt?
