The fronts line up with the outer rears . Its just an illusion from the angle how that photo was taken . For a better comparison here with a King Hauler body :
all-wheel-drive rig , but with bigger and wider tires .
Therefore the front tires stick out from the fenders ( and the rear is much wider as stock )

with stock semi-rims and tires they would be just covered by the fenders

here is a good photo from Travis's Mack :
