Starting April 15, 2025, a new regulation on vehicle tires takes effect in Italy, affecting tourists and travelers in particular. As of that date, it will no longer be permitted to drive on winter tires whose speed rating falls below the value specified in the vehicle registration document. This was reported, among others, by the Italian outlet altarimini.it. The regulation primarily concerns tires designed specifically for winter use, such as those marked "M+S" with a speed rating such as "T" or "H". The goal of the new rule is to significantly improve road safety during the summer months.
Italy: Winter Tires Banned from Mid-April
The measure is rooted in the fact that winter tires perform considerably worse in high temperatures. The rubber compound used in these tires is softer and optimized for cold conditions, making it unstable in the heat. This not only increases braking distances but can also negatively affect overall handling on dry roads. Combined with a low speed rating, the tires can overheat or even sustain damage, especially on long highway drives. The new regulation is intended to prevent exactly these kinds of risks.
The rule also affects many German drivers who often continue using winter tires after the cold season, sometimes out of convenience, sometimes out of unawareness. Until now, this was permitted in Italy outside the mandatory winter equipment period. The new rule states: between May 15 and October 15, tires with an insufficient speed rating may no longer be used, even if they are technically still in good condition.
Tread Depth Is Not the Deciding Factor
Important: contrary to common assumption, tread depth is not the deciding factor, but rather the speed rating approval. A winter tire with good tread but a speed rating that is too low will also be considered non-compliant during this period. The legally required minimum tread depth remains 1.6 millimeters, though at least 3 millimeters are recommended for summer tires and 4 millimeters for winter tires. Drivers with worn tires risk additional fines. Depending on the condition of the tires and the circumstances, police may impose fines ranging from 87 to 344 euros.
The new regulation applies not only to winter tires but also to so-called all-season tires. These may continue to be used provided they carry the correct speed rating and are in technically sound condition. The "M+S" marking alone is not sufficient. Anyone who is unsure should visit a tire specialist before driving to Italy.
Transition Period Until May 15
A transition period until May 15 gives drivers time to switch their tires accordingly. After that, penalties ranging from 422 to 1,682 euros apply. In serious cases, such as when a hazard to road traffic is present or in the event of a repeated violation, the vehicle's registration may even be revoked. Insurance providers may also reduce or deny coverage in the event of an accident if it is determined that the vehicle was equipped with non-compliant tires.
For anyone traveling through Italy by car in spring or summer, this means: make sure to switch to summer tires or suitable all-season tires in good time. Many repair shops anticipate increased demand around April, and those who wait too long risk longer waiting times or complications during a roadside check. The regulation applies regardless of whether the vehicle is used privately or commercially, and rental cars are also affected.
A Quick Check Can Prevent High Fines in Italy
Anyone driving in Italy, not just on highways, should verify before departure that their tires are not only in good technical condition but also comply with legal requirements. A quick check can, in case of doubt, prevent significant fines and unpleasant surprises, and ultimately contributes to greater safety on the road.
