Comparison: Kleber Dynaxer HP4 vs. Cooper Zeon CS8 vs. Sava Intensa UHP 2
Comparing the Kleber Dynaxer HP4 and the Cooper Zeon CS8 in independent summer-tyre tests shows a clear performance gap. Both are summer tyres, but their test results and overall ratings point to very different target customers and priorities.
Overall scores and test positions: the Kleber Dynaxer HP4 scores a strong 74% in our aggregated rating and placed consistently higher in major tyre comparisons (Autobild: 14th of 53; ADAC: 12th of 50). The Cooper Zeon CS8 sits much lower with a 34% rating and weaker placements (Autobild: 26th of 53; ADAC: 33rd of 50), so across mutual tests the Kleber is the better performer.
Strengths — Kleber Dynaxer HP4
- Comfort and low exterior noise: Autobild highlighted ride comfort and quietness as standout attributes.
- Durability and efficiency: Autobild 2024 praised its environmental balance, good tread life, abrasion resistance and efficiency — all important for long-term ownership costs.
- Balanced everyday performance: Good overall ranking in both Autobild and ADAC implies reliable all-round behavior for typical summer driving.
Weaknesses — Kleber Dynaxer HP4
- Not perfectly balanced: Autobild notes some weak points on wet roads that caused a small downgrade, so while competent, wet braking and hydroplaning margins are not class-leading.
Strengths — Cooper Zeon CS8
- Wet grip: Cooper retains acceptable wet-road performance in Autobild, which is one of the few positive highlights.
Weaknesses — Cooper Zeon CS8
- Poor dry performance: Autobild flagged significant shortcomings on dry roads, which led to downgrades and lower ranking.
- Low longevity and sustainability: Major negative marks for environmental impact, low mileage, poor abrasion resistance and poor efficiency — translating to higher running costs and faster replacement.
- Overall unbalanced behavior: Combined shortcomings make the tyre ill-suited for drivers who want predictable, economical summer performance.
Head-to-head verdict: in direct comparison the Kleber Dynaxer HP4 is clearly superior for most buyers. It delivers quieter, more comfortable driving, better durability and a stronger environmental/efficiency profile — all reflected by higher test rankings and a 74% aggregate score. The Cooper Zeon CS8 may still be acceptable if wet grip is your only priority, but its serious deficits on dry roads, low tread life and poor environmental marks make it hard to recommend except in niche situations.
Neither tyre is listed as being replaced by a newer model in our data, so you can consider these test results current for the referenced versions. For more details visit the manufacturer pages: Kleber (manufacturer) and Cooper (manufacturer).
