Load Carrying Capacity

SINGLE VERSUS DUAL
TIRE CAPACITY DIFFERENCES

Example - 275/70R22.5, LR H	Per tire, two tires per axle = 6610 lbs at 125 psi
	Per tire, four tires per axle = 6175 lbs at 125 psi

A tire mounted as a single can carry a greater maximum load than the same tire mounted as a dual. This is because tires in a dual set will carry unequal loads due to differences in the crown of the road. Tire to tire inflation pressure and tire diameter differences also factor into the difference in load capacity.
