Comparison: GT RADIAL ClimateActive vs. Kleber Quadraxer 3 vs. Hankook Kinergy 4S2

The comparison between the GT RADIAL ClimateActive and the Kleber Quadraxer 3 shows two competent all-round tyres with different strengths. On our scoring scale the GT RADIAL ClimateActive leads with 83% versus 79% for the Kleber Quadraxer 3, but test results are mixed depending on the discipline.

Summary of test highlights:

• Snow performance — Both tyres perform very well on snow. Autobild and Autobild 2024 note short braking distances and secure handling for the ClimateActive; the Quadraxer 3 is repeatedly praised as a “snow specialist” (Autobild 2025 calls it a “Schneekönig”) with winter-tyre level traction and handling.


• Wet handling and braking — This is the main divider. GT RADIAL is described as an excellent value tyre with no major weaknesses but shows slightly longer braking distances on wet and dry surfaces (ADAC 2017, Autobild 2024). Kleber often loses points for mistakes in wet conditions and shows mediocre wet grip / extended wet braking (Autobild 2025, Autobild 2024).


• Noise and comfort — Both tyres register good exterior noise values in tests. Kleber scores particularly well for comfort and low exterior noise in Autobild group tests; GT RADIAL also gets positive notes for external noise and snow braking.


• Aquaplaning and rolling resistance — Kleber shows solid aquaplaning reserves in Autobild 2024, while the Quadraxer 3 is also noted for respectable rolling resistance in some Autobild panels. GT RADIAL is highlighted as a budget-friendly option with competitive rolling resistance in ADAC commentary.


• Durability / mileage — GT RADIAL is criticised for somewhat limited tread life (Autobild 2024), a point to consider for high-mileage drivers.

Test positions across published reviews are close. In one Autobild group test the GT RADIAL ClimateActive placed 5th out of 11, while the Kleber Quadraxer 3 was 8th. In a larger Autobild comparison the Quadraxer 3 sat just ahead (7th) of the ClimateActive (8th of 37). These mixed placements underline that the two tyres trade places depending on the test focus (snow vs wet/dry performance).

Verdict: If you want a true all-rounder with a marginally higher overall score and consistently good behaviour on snow, dry and acceptable wet performance, the GT RADIAL ClimateActive is the safer pick — particularly for buyers prioritising value. The Kleber Quadraxer 3 is the better choice when winter/snow grip, comfort and aquaplaning resistance are top priorities: it behaves like a winter-focused tyre in snow and is praised for comfort and low noise, but you should accept somewhat weaker wet braking. In short: GT RADIAL = better overall score and value; Kleber = superior snow specialist and comfort.

Note: The Kleber Quadraxer 3 succeeds the Quadraxer 2 as Kleber’s current all-round winter/all-season offering.
