Front and rear axle loads

At 59/41, the 3,598 lbs puts about 2,123 lbs on the front axle and 1,475 lbs on the rear — 648 lbs more over the front wheels, which is what front tires and front brake pads wear against first.

How the figure moved since 2015

The lightest 2015 record is 3,774 lbs; the lightest 2020 record is 3,598 lbs — 176 lbs lighter (4.7%).

At the top of the range the 2020 file reaches 3,838 lbs against 4,226 lbs in 2015, a 388 lbs reduction — driven by which configurations exist, not by the same truck gaining mass.
