Practically New tires less than 30,000 miles on them...do the leaf springs have to be replace or is this something a commercial alignment place can fix
I personally have no idea what they’re talking about leaf springs offset.Are they saying the springs have no arch ?Leaf springs themselves don’t fail that often.More likely bad Chinese tires then springs
My guess is the leaves are shifted , crooked or not in line. May have nothing to do with the tire wear. Need more info- Year make model. Photos of springs and steer tires.
Springs are a fixed item. They have no adjustment. Unless it's an older truck with springs in the rear. Another idea would be worn or broken springs. Occasionally you see a truck where one side sits lower then the other side.
Spring “offset” can be one of two things. 1) Shifted/####ed to one side or the other due to worn shackle/hangers. Kind of like a toe in/out condition. 2) sitting twisted on the axle pad mount because of severe weakness/sag or loose/bent u-bolts or broken center bolt allowed them to shift forward or back in saddles. This is why checking the u-bolt nut torque is a good idea every year or so. springs can be “adjusted” by either re-arching them or using wedges/spacers on the saddles to reposition them at different heights/levels.
