Performance Analysis

The Kumho Solus 4S HA32 shows a mixed but coherent profile: consistently competitive in snow and wet braking for its class, average-to-weak in dry braking, and markedly strong in comfort/cost metrics in some tests. Its standout attributes are exceptionally low wear and excellent value in 2021, plus best-in-test noise in 2020. However, wet lateral grip (handling/circle/aquaplaning) and rolling resistance were recurring weaknesses, and dry braking often trailed class leaders. Overall placements skew lower-midpack, reflecting good winter braking and comfort/value offset by wet handling deficits and efficiency shortfalls.
