The tires are connected to the axle. They are acting the same as a floor jack on the axle. That means the axle won't compress the springs any further.
To correctly find the length of your bumpstops, you need to remove the springs with the vehicle supported by the frame.
Reinstall the shocks and then jack up the axle. You want your stops to hit about 1/2" before the shock bottoms out to allow for compression of the bumpstops.
Then install one spring on one side and move the floor jack over to the other side and jack it up. Depending on how the axle articulates, you may need to add or take away some bumpstop.
That's also a good time to slap a tire on and see how much trouble it will get into at full stuff.
