Comparing to the OE tires (Pirelli Scorpion Verde runflat), Kumho Ecsta PS71's side wall is notably softer, resulting in less road feedback. Steering is a bit vague around centre, but still precise when more steering is input. Afterall, sportiness is not the priority of this vehicle (2017 Mercedes-Benz GLC300 4MATIC). PS71 is comfortable over bumps, while its noise level is subjectively acceptable. Using them only for front tires for now, I have not driven them to the limit yet. So far no drama, wet or dry. I will keep an eye on them in the coming mileage. Reasonably priced, I am considering to buy another pair to replace the aging OE tires on rear axle.
