We are planning on starting a garage remodel in the spring and thinking about how to do the floor. We are considering laying 2 x 4's, 16 inches a part on top of some low cinder blocks and putting insulation between all them. The beams would be connected to the sides of the garage so there would be no movement. Then on top of that putting 1 inch plywood. Is this something that would be sturdy enough for a floor?

On top goes a car or truck?
Underneath the blocks is clay, sand, other?

The 2006 edition of the IRC states the following concerning floors in garages:
R309.3 Floor Surface
Garage floor surfaces shall be of approved, non-combustible material.
"
This is sort of an indoor residential floor construction. Residential loads are about 50 pounds/sq. ft. [PSF].
A tire that holds up 800# and has a footprint of 25 sq. in. is sort of a concentrated load @ 32 PSI which equals 4600 PSF.
Sounds like a bad idea for a garage floor.

Sorry, I should have made this a little more clear. This is for a garage renovation into a family room, so it will be just furniture, TV, etc. The current garage floor is the driveway tar. Not sure what type of base is inderneath the tar.
Better check with your local "building department" first and see if they have the wisdom to know the answer.
