As temperatures rise, the time to switch to summer tires approaches. While high-performance tires may be the go-to for many drivers of compact, speedy cars, they are not the only option. Regular touring tires, often more affordable, can also provide an excellent balance of comfort and energy efficiency. For instance, the Bridgestone Turanza 6 Enliten features low rolling resistance, making it a great choice for those looking to reduce fuel consumption. Conversely, the Continental PremiumContact 7 leans more towards performance. Meanwhile, the Michelin Primacy 4+ strikes a commendable balance between comfort and handling.
To assist drivers in selecting the best tires for the summer, the German magazine Auto Zeitung has conducted a thorough test of summer tires in size 225/45 R17. The test included well-established models like the Pirelli Cinturato P7 and Vredestein Ultrac, alongside newer offerings such as the Firestone Roadhawk 2 and the Hankook Ventus S1 evo3, which succeeds the previous generation Hankook Prime 4 in the touring tire market. For those with a tighter budget, the Falken Ziex ZE310 Ecorun and Maxxis Premitra 5 were also reviewed, offering good performance at a more affordable price point.
Test Conditions
The BMW 120i hatchback, equipped with a 178 hp turbo engine boasting 280 Nm of torque, served as the test vehicle for Auto Zeitung's summer tire test series. This model is known for its lack of parasitic forces affecting the steering under traction, providing a stable and confident drive even on wet roads. Its clear and precise chassis, which is firm without being overly stiff, proved ideal for evaluating touring category tires.
The main series of tire tests was conducted at the Bridgestone facility located on the outskirts of Rome. This test site is well-equipped for a detailed analysis of tire performance, featuring a high-speed oval, straight sections with certified pavement, and advanced irrigation systems designed specifically for conducting hydroplaning tests. This setup allowed for a thorough and controlled assessment of each tire’s capabilities under various conditions.
Testing of Tire Performance Across Disciplines
The tires featured in Auto Zeitung's test demonstrated remarkably close performance in safety-critical assessments, such as hydroplaning, braking, and handling. This closeness was particularly notable in the hydroplaning tests, where the gap between the best and worst performers was a mere 5 km/h.
Dry Braking
- Continental
- Pirelli
- Hankook
- Michelin
- Vredestein
- Maxxis
- Firestone
- Falken
- Bridgestone
Info! Dry braking in meters, (100-0 km/h).
Wet Braking

Info! Wet braking in meters, (100-0 km/h).
In dry asphalt braking tests from 100 km/h, the disparity was minimal, with only about two meters separating the least effective (Bridgestone) from the most effective (Continental), equating to a residual speed of 20 km/h. The variance widened in wet asphalt braking tests, where Michelin showed the longest stopping distance at 5.1 meters more than the best performer, corresponding to a residual speed of 30 km/h.
Straight Hydroplaning

These results highlight a fundamental challenge for tire engineers: balancing the need for maximum grip, which ensures shorter stopping distances, with the desire for low rolling resistance to enhance fuel efficiency. Continental's performance illustrates this trade-off. The ability to merge these two attributes effectively could provide a significant technological edge. However, for now, the preference for grip or fuel economy depends on the tire's intended use, and it's up to the consumers to prioritize what matters most to them—superior handling or better energy efficiency.

Overall Verdict
This tire test underscored Continental's continued leadership in the touring tire segment, maintaining its top position even with a higher rolling resistance. Pirelli, placing second, exhibited a sporty disposition but fell short in terms of comfort. The affordable Hankook model emerged as the best value for money, offering impressive features at a lower cost.
The new Firestone model, ranking fifth, proved to be economical and well-balanced, demonstrating solid performance across various tests. Vredestein, despite its subpar braking on wet surfaces, secured fourth place due to its overall combination of characteristics.
At the bottom of the rankings, Falken, Michelin, Maxxis, and Bridgestone required significant compromises. These brands showcased areas needing improvement, particularly in balancing performance features with comfort and efficiency, positioning them as less favorable in this competitive testing environment.
Results
1st Place: Continental / PremiumContact 7
Quick Take
Continental PremiumContact 7
The Continental PremiumContact 7 is a dependable tire that performs consistently on both dry and wet surfaces, ensuring good control and handling in various driving situations. It responds quickly to steering, which enhances the overall driving experience. While it stands out for its performance in handling and braking, it's important to note that the tire's rolling resistance is on the higher side. This means that while it delivers in terms of safety and control, it might not be the best option for drivers who are particularly focused on maximizing their vehicle's fuel economy.
2nd Place: Pirelli / Cinturato P7 (P7C2)
Quick Take
Pirelli Cinturato P7 (P7C2)
The Pirelli Cinturato P7 C2 showcases strong performance, especially in dry conditions, closely trailing the leader with minimal differences.
