feel kinda foolish askin this, but i figure id rather feel foolish than feel squished under a car.. ive started doing enough work on the vx that i can justify buying a jack/jack stands set, theres an "inexpensive" craftsman set rated at 2-1/4 tons, does this mean i can use it to hold up a vehicle thats 2-1/4 tons.. or that each jack stand can hold up 2-1/4 tons so i could hold up a 9 ton vehicle with four of them?

thanks all
