Wet
In wet braking, the Kumho Ecsta HS52 stops 1.6 meters shorter than the Michelin Primacy 5, which is about a 5% advantage in braking distance. This gives the Kumho a noticeable edge in emergency stopping performance on wet roads. However, in straight-line aquaplaning, the Kumho also holds on 0.8 km/h longer than the Michelin, translating to about a 1% advantage in resisting water lift at higher speeds.
Overall, the Ecsta HS52 shows slightly stronger wet safety performance, though the differences remain relatively small between the two touring tires.
Primacy 5 :
- -5% in wet braking
- -1% in aquaplaning
Dry
In dry braking, the Kumho Ecsta HS52 stops 0.6 meters shorter than the Michelin Primacy 5, which translates to about a 2% advantage in braking distance. This gives the Kumho a slight edge in dry emergency stopping performance, though the difference between the two touring tires remains fairly small in real-world driving.
Primacy 5 :
- -2% in dry braking
Wear
In mileage, the Michelin Primacy 5 lasts 12,800 km longer than the Kumho Ecsta HS52, reaching 56,000 km versus 43,200 km, which translates to about a 30% advantage in total wear life. This is supported by the abrasion results, where the Michelin loses 37 mg/km/t less rubber than the Kumho — 54 mg/km/t versus 91 mg/km/t — representing roughly a 41% lower wear rate.
Together, these results clearly show the Primacy 5 delivering significantly stronger longevity and durability compared with the Ecsta HS52.
Primacy 5 :
- +30% in mileage
- +69% in abrasion
Fuel Consumption
In fuel consumption, the Michelin Primacy 5 uses 0.4 l/100 km less fuel than the Kumho Ecsta HS52, recording 5.4 l/100 km versus 5.8 l/100 km, which translates to about a 7% advantage in efficiency. This gives the Michelin a clear edge in rolling efficiency and long-distance fuel savings compared with the Kumho.
Primacy 5 :
- +7% in fuel consumption
Price
For the tested 225/50R17 size, the Kumho Ecsta HS52 costs €87, while the Michelin Primacy 5 is priced at €132. This means the Primacy 5 is €45 more expensive, translating to about a 52% higher price compared with the Ecsta HS52.
