Comparison: Toyo Celsius AS2 vs. Firestone Multiseason 2 vs. Kumho HA32 Solus 4S

Short comparison: the Toyo Celsius AS2 (54%) and the Firestone Multiseason 2 (56%) are both positioned as all‑round / multiseason solutions, but tests show they follow different priorities. Neither model has a listed direct replacement at the time of testing.

Test positions and overall result: across the available test programmes (AUTOBILD, ADAC and other lab comparisons) the Firestone generally ranks marginally ahead. Example placements: AUTOBILD/ADAC runs show Firestone at positions like 11–22 and ADAC 8/16, while Toyo sits around 11–12/16 or lower in larger AUTOBILD fields. Combined with the small difference in our aggregate scores (56% vs 54%), the Firestone Multiseason 2 is the overall winner by a narrow margin.

What the tests say — strengths

• Toyo Celsius AS2 – praised repeatedly for high mileage, very good price/value and comfortable ride with low exterior noise. Several tests highlight strong aquaplaning resistance and long wear life, making it a good choice if you prioritise economy and comfort.


• Firestone Multiseason 2 – scores best for wet handling, very good snow grip and consistently low rolling resistance. Tests note excellent behaviour on wet laps and strong performance in snow tests, which helps fuel efficiency and winter safety.

What the tests say — weaknesses

• Toyo Celsius AS2 – several test reports point to average winter qualities, understeer on snow and wet surfaces, delayed steering response on wet roads and prolonged wet braking distances. If winter handling precision and shortest wet braking are priorities, Toyo shows limits.


• Firestone Multiseason 2 – despite its wet and snow strengths, Firestone is criticised for extended dry braking distances, slightly below‑average comfort and mixed notes on aquaplaning reserves in some tests. Some test years also reported inconsistent treadwear/longevity.

Head‑to‑head summary: On pure safety metrics for wet and snowy conditions the Firestone pulls ahead thanks to better wet handling and superior snow grip, while the Toyo wins on cost‑per‑kilometre, comfort and aquaplaning reserves. In mixed real‑world use the Firestone’s strength on wet and snow combined with lower rolling resistance makes it the more balanced performer overall; the Toyo is the better value and longer‑lasting option if you prioritise mileage and ride comfort.

Verdict: choose the Firestone Multiseason 2 if you want the slightly better all‑round safety in wet and snowy conditions and lower rolling resistance. Opt for the Toyo Celsius AS2 if your priorities are longevity, price/value and comfort and you can accept modest compromises in wet braking and winter handling.
