Pueden servir de algo si se dejan bajo la rueda al aparcar, pero no sirven para nada si la rueda "amanece" en suelo blando resbaladizo (arcilla, césped). Las usamos en terreno blando para evitar que las cuñas elevadoras se hundan y "arponen" la carrocería, para eso nos van muy bien.

These are so light and thin that I carry them in my camper permanently.I have used them just once so far on a site in the Spanish Picos on sodden grass. I used them under the front wheels when I parked up and next morning although the rear wheels had sunk into the ground by about an inch the fronts were fine and I was able to drive out with no problem.This is certainly the way to use them, rather than after you've bogged down.

We bought these to help get our grandsons electric wheelchair on and off the sand, they were lightweight enough to pop in our trolley but sturdy enough to cope with a heavy wheelchair on sand. We purchased two sets so that we could take a set to the front of the chair move it and so on - they will also be great just to have in the car in winter for mud and snow.
