Data updated
Which should you buy?
Choose the Nexen N Blue 4Season 2 if you want a genuinely usable all-season tyre for mixed conditions (rain, standing water, and occasional snow/ice) and you value comfort; avoid the Roadhog RGAS02 for true all-season duty because its aquaplaning and winter deficits dominate the real-world risk profile, despite its slightly better straight-line braking on dry/wet asphalt.
Where the N Blue 4Season 2 is stronger
- Clearly better aquaplaning resistance (81.1 vs 74.7 km/h straight; 3.2 vs 2.4 m/s² curved)
- Stronger winter capability: better snow braking/traction and shorter ice braking (e.g., ice 20.5 m vs 22.5 m)
- Lower noise levels in test (69.8 vs 72.7 dB)
Where the RGAS02 is stronger
- Consistently shorter dry braking in both shared tests (e.g., 40.0 m vs 42.6 m in ADAC)
- Consistently marginally shorter wet braking in both shared tests (e.g., 35.1 m vs 35.6 m in ADAC)
- Lower abrasion measurement in ADAC (68 vs 72 mg/km/t)

Wins count every measurement the shared tests recorded for both tyres; a tick marks the tyre 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 2 tests, 2025 to 2026
Each row is one published test in which both tyres 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 tyres shared. "Scored" rows are subjective driver ratings: each test uses its own scale, so only the wins are counted.

- 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 tyre. 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 tyre
- Soft/squishy feel or sidewalls when pushed
Summarised by AI from 12 vetted reviews; the reviews themselves are on the tyre 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 is a comparison between two budget-leaning all-season touring tyres aimed at everyday passenger cars: the Nexen N Blue 4Season 2 and the Roadhog RGAS02. Both target the same “one set year-round” buyer, but the shared test data shows they go about that brief very differently-especially once conditions turn wet, wintry, or waterlogged.
Across two shared test sets (including ADAC's demanding 185/65 R15 all-season test), the Roadhog often posts slightly shorter braking distances on dry and wet asphalt in straight-line stops, while the Nexen answers back with clearly stronger aquaplaning resistance, better snow/ice capability, and noticeably better refinement. The result is a trade-off between marginal braking wins in benign conditions versus broader all-season safety margins and day-to-day comfort.
Conclusion
Looking at the combined evidence, the Nexen N Blue 4Season 2 is the more rounded all-season tyre of these two, even though it is not a class leader. In ADAC's 185/65 R15 test it decisively outperformed the Roadhog in the areas that typically separate acceptable all-seasons from risky ones: aquaplaning (81.1 vs 74.7 km/h straight aquaplaning and 3.2 vs 2.4 m/s² curved), winter braking/traction (e.g., snow braking 12.1 m vs 13.1 m; ice braking 20.5 m vs 22.5 m), plus it was quieter (69.8 vs 72.7 dB) and projected slightly longer wear (37,200 vs 35,000 km). That said, ADAC still criticized the Nexen for weak dry and wet grip versus better tyres in the field-so it's a “better of these two” call, not a blanket endorsement.
The Roadhog RGAS02's main advantage is small but repeatable straight-line braking wins on dry and wet asphalt across both tests (e.g., 42.6 m vs 40.0 m dry braking in ADAC; 40.2 m vs 38.5 m in the 225/40 R18 test, with similarly tiny wet braking edges). However, ADAC's qualitative verdict is damning: poor winter performance and early aquaplaning are exactly the kinds of limitations that turn an all-season tyre into a fair-weather tyre. Practical takeaway: if you truly need an all-season tyre for mixed weather, the Nexen is the safer, more usable option; if you're considering the Roadhog purely for price, the data suggests its wet/winter and aquaplaning deficits are not worth the savings.

Where this data comes from
Finishing positions and measurements are transcribed from each published test. A test only counts here when both tyres 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 Tyre Reviews Score rates each tyre out of 10 from every independent test result and vetted owner review we hold, so two tyres can be compared even before a test has run them together.
Who does the testing
Every test published as a Tyre Reviews test is run by Jonathan Benson, who has been testing tyres independently since 2007.
