The Toyo Celsius AS2 tire receives an overall adequate rating for driving safety. It shows significant weaknesses on dry roads at high temperatures and clearly misses good ratings on both wet and winter surfaces.

On dry surfaces, the tire offers barely adequate steering feedback and lacks precision. The driver must make frequent corrections due to delayed steering response and inconsistent cornering. The test vehicle tends to oversteer early in dynamic maneuvers, resulting in an adequate rating for limit behavior. Braking distance is rated as satisfactory.

On wet roads, the Celsius AS2 performs satisfactorily overall. It receives good ratings for aquaplaning resistance but narrowly misses a good rating in braking. Its handling is rated as merely adequate, struggling to combine longitudinal and lateral forces effectively and showing early and pronounced under- or oversteer.

In winter conditions, the Toyo achieves a satisfactory result. It scores well in snow and ice braking, but only satisfactory in traction and snow handling. The test vehicle offers satisfactory steering precision, but with a narrow and low performance limit.

Environmentally, the Japanese-made Toyo Celsius AS2 receives a good rating. It scores well in both projected mileage and wear. The tire also impresses with its efficiency, showing comparatively low weight and fuel consumption.
