Ranked #8 of 9
Finishing 8th out of 9 competitors, the Kumho Ecsta PS91 showed a decent performance in some aspects but fell behind in current standards, with plans for a successor already underway. Its strongest selling point, for now, is its cost-effectiveness. The tire delivered solid results in the wet braking test and aquaplaning, demonstrating its capability to handle wet conditions. However, its tendency toward understeer and conservative handling around wet tracks highlighted a limitation in its sporting credentials. On dry surfaces, the tire was critiqued for providing limited feedback and reacting imprecisely to sudden directional changes, with a noticeable understeer at the limit and a higher rolling resistance.
