Do Rear Wheels Need Dynamic Balancing?

[Craig]

Two reasons whether rear wheels need dynamic balancing: 1. Necessary: Involves wheel disassembly/reassembly (1) When replacing rims, tires, patching tires, installing TPMS modules, or changing valve stems of different materials, tire dynamic balance needs readjustment. (2) For asymmetric tread or unidirectional tread tires - both have fixed rolling directions and can only rotate one way. Installation must ensure correct orientation to prevent reduced wet traction. 2. Unnecessary: Only involves wheel assembly removal (1) When simply rotating tires front-to-rear, as this only involves wheel assembly repositioning.
