I don't think it takes any weight at all.  When I've filmed 767s landing
on the forward trucks first, the rear trucks touch down immediately
afterward even though it's obvious the wing is still carrying a good part
of the plane's weight and the nose is still being held off in the flare.
To my knowledge, there is no spring force to be overcome.  The wheel
assemblies just hang naturally in that position, unlike the 777 main gear
which is powered into and out of its rearward slant position from the
horizontal.
