Comparison: Semperit Speed-Life 3 vs. Goodyear Efficient Grip Performance 2 vs. Kumho Ecsta HS52 vs. Michelin Primacy 4+

When it comes to summer tyre performance, the Semperit Speed-Life 3 and the Goodyear Efficient Grip Performance 2 are major contenders. Built by trusted manufacturers, Semperit and Goodyear respectively, both tyres have distinctive strengths and weaknesses, each excelling in different conditions and performances.

Semperit Speed-Life 3 is the successor of the Semperit Speed-Life, demonstrating improvements in different areas. With our rating of 59%, this tyre’s best performing features include wet braking, evident in the 'Autobild' test where it clinches the 12th position out of 53. Coupled with its good handling on wet roads, high projected mileage, and low wear, the Semperit Speed-Life 3 ensures efficiency and longevity. However, it falls a bit short in terms of dry road drivability.

On the other hand, Goodyear Efficient Grip Performance 2, also succeeding Goodyear Efficient Grip Performance, earned a stellar rating of 84% from our tests, demonstrating high performance across different conditions. At 'Autobild', it landed at the 13th position. Its highlighted characteristics are impressive mileage, price value, comfort, and short braking distances. Like the Semperit tyre, it also exhibits high predicted mileage and low rolling resistance. However, it is noted to have a relatively higher price level.

In 'ADAC' mutual test, Semperit Speed-Life 3 took the impressive 2nd place out of 15, excelling particularly in aquaplaning - cross, exterior noise, and wet braking. Goodyear Efficient Grip Performance 2, on the other hand, secured the respectable 4th position, with mileage being its best feature.

To wrap up, Semperit Speed-Life 3 stands out due to its wet braking ability and overall efficiency, despite its weakness on dry road drivability. Meanwhile, Goodyear Efficient Grip Performance 2 proves to be an exceptional all-rounder, combining mileage, comfort, and value, albeit at a higher price level.

When choosing between these two, potential customers should weigh their individual driving conditions and requirements. The data gathered from different tests provides a clear comparison of their performances, making it easier to identify the tyre that perfectly fits their needs.
