The Kumho Ecsta PS91 is a mid-range summer tyre that performs solidly in wet conditions, with good results in braking tests and aquaplaning. However, it is noted that it is overly focused on understeering, making it less suitable for sporty driving. On dry roads, the tyre is less impressive, with only moderate feedback and imprecise reactions to sudden changes in direction. At the limit, it tends to understeer and has a high rolling resistance. Overall, the Kumho Ecsta PS91 is seen as a decent tyre, but not on par with the latest offerings in the market. Its main selling point is its low price. The tyre offers decent water drainage, acceptable grip in turns, and low reaction times in wet conditions. On dry roads, it provides good braking performance and is very quiet. On the negative side, it has longer braking distances and noticeable understeering in wet conditions, along with slow turning response and high rolling resistance. These test results were published by autozeitung and sportauto, in different dimensions (235/35 R19 and 225/40 R18).


Kumho Ecsta PS91 is made in 48 sizes, starting from 225/40 R18 up to 275/30 R21.

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.
