Comparison: Michelin Primacy 3 vs. Semperit Speed-Life 2 vs. Goodyear Efficient Grip Performance 2 vs. Falken e.Ziex vs. Goodyear Efficientgrip 2 SUV vs. GoodYear Efficientgrip Performance 2

In this comparative review, we shall discuss two formidable summer tyres, the Michelin Primacy 3 and the Semperit Speed-Life 2. Both tyres have shown versatile performance across various tyre tests and have been the preferred choice of many drivers. They have now been replaced by newer models, the Michelin Primacy 4 and the Semperit Speed-Life 3, respectively.

The Michelin Primacy 3, a product from established brand Michelin, presents reliable performance. In your ACE test, it came in ninth, while it overshadowed its competitors by securing the top position in the ADAC test. However, in the extensive Autobild test, which featured 50 tyres, it managed to secure a moderate tenth position. While the actual ratings are not provided, these test positions point to reasonable all-around performance.

On the other hand, the Semperit Speed-Life 2, manufactured by Semperit, exhibited somewhat varied performance. It lagged slightly behind its counterpart in the ACE and ADAC tests by securing the tenth and sixth positions, respectively. However, in the more comprehensive Autobild test, it leapt to the third position. Furthermore, it was singled out for its excellent rolling resistance, proving it to be a fuel-efficient tyre.

The data here does not necessarily point to a clear winner. For someone looking for a tested and reliable all-rounder, the Michelin Primacy 3 could be a safer bet, renowned for its overall consistency. However, for motorists specifically seeking fuel efficiency, the Semperit Speed-Life 2, with its superior rolling resistance, would be the preferable choice.

It's worth noting that these models have been replaced by the Michelin Primacy 4 and Semperit Speed-Life 3. Hence, potential buyers interested in these tyres' performance characteristic should definitely check the newer models, as they likely carry forward the strengths of their predecessors while aiming to improve upon any weaknesses.
