Data updated
Which should you buy?
Choose the GT-Radial ClimateActive if your priority is wet-weather safety and hydroplaning resistance (frequent rain, higher-speed wet driving, motorway use). Choose the Nexen N Blue 4Season 2 if you value a quieter, more comfortable ride and good dry braking, and you can accept that wet-grip limits (especially aquaplaning) are the main compromise.
Where the ClimateActive is stronger
- Consistently stronger wet braking across all shared tests (3/3 wins), including a large advantage in the 2024 overview (56.6 m vs 61.4 m)
- Clear aquaplaning edge in both straight and curved tests (e.g., 87.3 vs 81.1 km/h straight aquaplaning in ADAC 2026; +18.8% curved aquaplaning there)
- Slightly better snow braking and traction in the two tests that measured them (small but repeatable advantages)
Where the N Blue 4Season 2 is stronger
- Quieter in both tests that measured noise (e.g., 69.8 vs 71.9 dB in ADAC 2026; 70.5 vs 72.2 dB in AutoBild 2025) and praised as the quietest in ADAC
- Better dry braking in 2 of 3 shared tests (e.g., 38.5 vs 40.1 m in AutoBild; 39.4 vs 40.9 m in 2024 overview)
- Better ice braking in ADAC 2026 (20.5 vs 20.9 m) and noted as one of the shortest stoppers on ice in that test context

Wins count every measurement the shared tests recorded for both tires; a tick marks the tire ahead on that line. Subjective driver scores count as wins but are never averaged, because each test uses its own scale.
Head to head in 4 tests, 2024 to 2026
Each row is one published test in which both tires ran on the same car, in the same size, on the same day. The line is the whole field, winner on the left.

Braking distances and lap times are better when lower; speeds, wear and grip figures when higher. A test's figures are its own: sizes, cars, surfaces and temperatures differ from one to the next, which is why the averages here are only ever of tests the two tires shared. "Scored" rows are subjective driver ratings: each test uses its own scale, so only the wins are counted.

GT Radial ClimateActive
- 87%from 4 reviews
- 25,500 milesdriven by reviewers
Drivers report the GT Radial ClimateActive delivers strong all-season performance, with confident grip in dry and heavy rain and notably good traction in mud and gravel. Comfort and refinement are frequently praised, and multiple users highlight strong value versus premium alternatives like the Michelin CrossClimate 2. Wear so far appears competitive based on early mileage reports, with only a minority noting slightly vague steering/less road feedback.
- Strong wet and dry grip with confident all-year performance
- Good traction on mud/gravel (useful for fields and rougher surfaces)
- Comfortable ride and generally quiet/refined driving
- Good value for money versus premium competitors
- Steering/handling can feel a bit vague or have reduced road feedback
Summarised by AI from 4 vetted reviews; the reviews themselves are on the tire page.
All 4 ClimateActive reviewsI fitted this tire on a new Fiat 600 hybrid, straight at car delivery, replacing the OE summer Goodyear's. I therefore have no benchmark compared to the summer OE's.
Fitted in early December, i had the chance to drive them on dry, wet and also some snow due to latest weather conditions.
the tire was superb in all levels of grip. it is also very quiet and comfortable, despite the 18 inch and (relative) low aspect ratio.
Handling is soft and with delayed response, but i attribute this more to the car overall soft suspensions and chassis settings, rather than the tire itself.
A very good tire at a fantastic price point. And apparently the press agrees with me.
Well done GT!
Nexen N Blue 4Season 2
- 78%from 15 reviews
- 86%would buy again
- 145,500 milesdriven by reviewers
With an 80% average score and 10 of 12 reviews rating it positively, owners generally find the Nexen N Blue 4Season 2 to be a capable all-season option with dependable dry and wet grip, plus reassuring traction in snow for everyday driving. A notable minority mention ice performance, and opinions are mixed here (around a third of owners commenting), with a couple finding it excellent and a similar number reporting it's not as confidence-inspiring as a dedicated winter tire. Comfort and refinement also come through strongly, with several owners describing it as particularly quiet.
- Strong dry grip for an affordable all-season
- Confident wet grip in mixed conditions
- Surprisingly capable traction in snow
- Very low road noise
- Mixed ice grip versus a proper winter tire
- Soft/squishy feel or sidewalls when pushed
Summarised by AI from 12 vetted reviews; the reviews themselves are on the tire page.
All 15 N Blue 4Season 2 reviewsIn the meantime, I've driven 32,000 miles (51,000 km) on these tires (see current photos), and I have to say, they're still performing excellently on my car. Summers here are hot, and winters are mild; we rarely get snow, just wet and slushy roads. These all-season tires are the perfect choice for these conditions, eliminating the need for unnecessary tire changes (except for swapping the front tires to the rear and vice versa). And they’re a great fit for my car (Kia Optima K5). The only downside is that at highway speeds, within a certain speed range, a pulsating noise occurs due to the tread pattern, but as soon as the speed goes above or below that range, it goes away. I highly recommend them for everyday driving—I’d buy them again.

Reading the results
Written from the test results and owner reviews above. It is analysis, not a measurement: where it and the tables disagree, the tables are right.
This comparison pits two value-oriented all-season touring tires with slightly different priorities: the GT-Radial ClimateActive (positioned as a premium-touring all-season) versus the Nexen N Blue 4Season 2 (a touring all-season with a strong comfort/refinement angle). Across three shared, independent tests (ADAC 2026 in 185/65 R15, AutoBild 2025 in 215/55 R17, and a 2024 market overview in 225/50 R17), they consistently land mid-pack overall-close enough in ranking to make the decision come down to the type of weather you see most.
Conclusion
Across the shared data, the GT-Radial ClimateActive builds its advantage where all-season tires most often get exposed: wet safety and aquaplaning. It wins wet braking in all three shared tests, including a meaningful gap in the 2024 overview (56.6 m vs 61.4 m, about 7.8% shorter), and it repeatedly resists aquaplaning better (e.g., straight aquaplaning 87.3 vs 81.1 km/h in ADAC 2026; stronger curved aquaplaning in both ADAC and AutoBild). If you drive in a rain-heavy climate, do lots of motorway mileage in wet conditions, or simply prioritize “safe and stable when it pours,” the ClimateActive's pattern of results is hard to ignore.

Where this data comes from
Finishing positions and measurements are transcribed from each published test. A test only counts here when both tires ran in it, so every figure was recorded on the same car, size and day as the one it is compared to.
About the TR Score
The Tire Reviews Score rates each tire out of 10 from every independent test result and vetted owner review we hold, so two tires can be compared even before a test has run them together.
Who does the testing
Every test published as a Tire Reviews test is run by Jonathan Benson, who has been testing tires independently since 2007.
