Not sure if these numbers are right but they might give some explanation.
Me-262 Empty weight 3800kg/wing area 21,7m2 = 175kg/m2 wingload.
Max. weight 7130kg/wing area 21,7 = 328kg/m2
P-47-D-30 Empty weight 4812kg/wing-area 27,9m2= 172kg/m2
Max.Weight 7900kg/wing-area 27,9m2=283kg/m2
Light Me-262 has almost same wingload than light P-47.
