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).
