We did not use any chocks in storage. Flat concrete floor, so no need. Friction of tongue jack held all from movement. However, on the road - X-chocks always and wheel chocks if the grade was unusual. Often chock tow vehicle too.
The tires will age out before you damage them with X-chocks and if stored outside, a lock on the screw provides just that little bit of extra security.
