I have Snap Pads on these. Both the center and the rear set, I have dragged one off of each set because of bottoming out. Luckily, because of the Snap Pads, I did not damage the levelers, and only had to put the Snap Pad back on.
Look at getting a set of Snap Pads, they do help. Even if they are only 1-2 inches thick, they do help with the larger footprint. I do really like the Snap Pads.
