Italy tire regulations: Winter vs. All Season performance and legal requirements

As the seasonal change approaches, drivers in Italy must navigate specific legal requirements and technical differences between winter and all-season tires. According to Assogomma, winter tire mandates or the requirement to carry snow chains will be in effect from November 15, 2026, until April 15, 2027, on roads covered by specific local ordinances.

Technically, winter tires are engineered with specialized rubber compounds rich in silica and low-temperature polymers. This allows the tread to remain elastic and soft even in freezing temperatures, whereas standard tires may become rigid and lose grip. While all-season tires have seen significant engineering improvements, they still face physical limits in extreme cold compared to dedicated winter models.

For legal compliance in Italy, winter tires are identified by the M+S marking, while the 3PMSF (Three Peak Mountain Snowflake) symbol denotes higher performance standards. Assogomma emphasizes that choosing the correct tire is a critical factor for active vehicle safety, affecting traction, braking, and cornering on ice, frost, and wet surfaces.
