I'm providing this information so that readers may be informed, not to dispute any of the information already provided. The information is a copy of the correspondence between myself and Joe Portelli of HWH Corp.
The jacks will support the weight of the tires being off of the ground. We
do try to shy people away from putting blocks under the jacks for extra
lifting, because the potential to fall of the blocks is great. The only time
we recommend using blocks in the leveling process is if you are on soft
ground, then using a two by is not a bad idea.
Hopefully I have answered your question, if you have any other questions
feel free to contact me.
