I have talked with the engineers at Tate Access Flooring several times. 
I don't think that they gave me numbers that were excessively 'safety 
padded'.  For example they told me that the 1250 floors would support 
approximately three times that point load before structural collapse. 
However the tiles would have irreversible deformations greater than 0.1" 
if the point load exceeded 1250 pounds.

So I suggest that you call the flooring company first, then decide if you 
believe what they tell you.

Cheers,
