Comparison: Kleber Dynaxer HP4 vs. Semperit Speed-Life 3 vs. Cooper Zeon CS8 vs. Pirelli P ZERO PZ4 vs. Goodyear Efficient Grip Performance 2

In this comparative review, we focus on two summer tyres, the Kleber Dynaxer HP4 and the Semperit Speed-Life 3. Both tyres have been subjected to rigorous testing, where various strengths and weaknesses have been unveiled.

The Kleber Dynaxer HP4 is rated at 82% by our team. Its strength lies in its comfort and low exterior noise level. It performed well on dry surfaces and is also efficient, with low fuel consumption. One of the notable features of this tyre is its eco-friendliness, which was particularly highlighted during the Autobild 2024 test. Dynaxer HP4 rated 14th out of 53 tyres, however, it displayed issues on wet surfaces in both Autobild 2024 and ADAC 2021 tests.

On the other hand, the Semperit Speed-Life 3 bears a rating of 65%. Its previous model being the Semperit Speed-Life indicates that it's a further development of an existing line. The tyre excels particularly in wet conditions, as tests by Autobild and ADAC in 2021 demonstrated, ranking this tyre 12th out of 53 and 10th out of 17, respectively. Its weakness on dry surfaces and environmental performance were marked down in the test results.

When it comes to the mileage, the Kleber Dynaxer HP4's higher tire wear in ADAC 2021 test and good performance in Autobild 2024 test is noticeable. Contrarily, the Semperit Speed-Life 3 showed commendable resistance to wear in the ADAC 2021 testing.

In conclusion, while both tyres have their own strengths and weaknesses, the Kleber Dynaxer HP4 trumps in terms of comfort, low noise and fuel efficiency but struggles on wet surfaces. The Semperit Speed-Life 3, however, gains high marks on wet surfaces and tyre wear but lacks in dry surface performance and environmental impact. Therefore, the choice between the two will largely depend on your driving preference and requirements.
