Auto Motor Und Sport: Summer Tire Test R17 2025

Auto Motor Und Sport tested 215/55 R17 summer tires in 2025, prioritizing sustainability alongside traditional performance metrics. The trial evaluated three eco-focused areas:

Use of recycled/renewable materials in manufacturing.
Transportation distances from factories to reduce carbon footprints.
Real-world fuel efficiency via rolling resistance.

Testing used synthetic e-fuels and HVO diesel to minimize emissions. Michelin’s e.Primacy, made carbon-neutrally in Germany, led in efficiency but lagged slightly in wet handling. Continental’s UltraContact NXT used sustainable materials like rice husk ash and recycled PET, balancing eco-credentials with strong wet/dry performance. Falken’s e.Ziex combined affordability with competitive results, while the retreaded Insa Turbo EcoEvolution struggled with high rolling resistance despite its reuse focus.

Results showed trade-offs: some tires excelled in sustainability but compromised on grip or noise, while others balanced both. The test highlighted that "green" tires still face challenges in matching premium safety standards universally.

Continental UltraContact NXT - Winner

N/A 35

· Summer · 2023 · Passenger - Premuim Touring Summer

Verdict:
The Continental UltraContact NXT claimed joint first place in Auto Motor Und Sport’s test, excelling with the shortest wet braking distances and secure dry handling featuring predictable understeer and high cornering stability. Its innovative sustainable construction—using bio-based silica, recycled PET, and reclaimed steel—paired with low rolling resistance (EU Label A/A/69) redefines eco-conscious performance, though dry braking trails slightly behind class leaders.

Falken e.Ziex

N/A 25

· Summer · 2023 · Passenger - Premuim Touring Summer

Verdict:
The Falken e.Ziex tied for first place, combining best dry braking performance with dynamic wet handling and low rolling resistance (EU Label A/A/71). Its sustainable construction (29% recycled/biomaterials) and €125 price deliver exceptional value, though slightly reduced aquaplaning resistance limits wet safety margins.

· Summer · 2023 · Passenger - Premuim Touring Summer

Verdict:
The Bridgestone Turanza 6 ranked third, excelling in wet cornering grip and best-in-test aquaplaning resistance, paired with neutral dry handling. Its sustainability focus on longevity and EU Label B/A/70 fuel efficiency comes at minor costs: slightly extended wet braking distances, reduced comfort, and elevated cornering noise.

· Summer · 2020 · Passenger - Premuim Touring Summer

Verdict:
The Michelin e.Primacy ranked fourth, combining class-leading efficiency (EU Label A/B/70) with exceptional comfort and CO₂-neutral production. Its low rolling resistance and extended tread life optimize EV range, though longer wet/dry braking distances and reduced wet cornering grip impact dynamic safety.

· Summer · 2020 · Passenger - Premuim Touring Summer

Verdict:
The Goodyear EfficientGrip Performance 2 ranked fifth, leveraging Mileage-Plus technology for 50% greater longevity, ideal for heavier EVs. It excelled in wet conditions with precise handling and strong braking safety, though dry braking distances lagged behind competitors. Its EU Label B/A/70 highlights balanced efficiency but slightly elevated rolling resistance.

Insa-Turbo EcoEvolution

N/A 13

· Summer · 2012 · Passenger - Premuim Touring Summer

Verdict:
The Insa Turbo EcoEvolution ranked last, exemplifying critical safety flaws with dangerously long wet/dry braking distances, severe understeer, and erratic handling. Its retreaded construction caused vibrations, loud noise, and high rolling resistance (10% fuel penalty), failing high-speed tests. Priced at €77, it prioritizes cost over safety and efficiency, earning a “deficient” rating and strong recommendation against passenger vehicle use.
