Winter Tires vs Chains in Italy: What the Law Requires
In Italy you do not have to choose between winter tires and snow chains: on roads marked with the obligation, either one satisfies the law. The rule applies on signed roads from November 15 to April 15. Either your car wears approved winter tires, or it carries approved anti-skid equipment that you can fit on the drive wheels. Which one is smarter depends on your route, your car and how much you value a quiet, unhurried arrival.
TL;DR
On signed roads, the Italian rule is winter tires or chains on board, from November 15 to April 15. Local ordinances can extend those dates.
Winter tires must carry an M+S or 3PMSF marking. Chains must be homologated; certified snow socks count as well.
Outside built-up areas, the fine is €85, and officers can order you not to continue your journey.
Chains in the trunk are a legal answer. Winter tires on all four wheels are a better driving answer, especially in the Alps and Dolomites.
For a rental, confirm tires and chains before you accept the keys, and above all with a high-performance car.

What the Italian rule actually says
The national framework comes from a 2013 directive of the Ministry of Infrastructure and Transport. It sets out that vehicles must have homologated winter tires or carry compatible, approved anti-skid devices. If you use the devices, they must be mounted at least on the drive wheels. The same directive sets the standard winter period as November 15 to April 15.
Two details matter in practice:
The rule is not blanket. The State Police explain that road owners and managers decide where to require winter equipment, and signs identify the affected sections. A motorway ramp near Milan may have no sign at all, while the road to a mountain resort will.
Motorcycles and mopeds are outside the mandate, though they may be barred from roads with snow or ice.
In short, the law is built around the road, not around the car. You learn what applies by reading the signs on the way up, and by checking local requirements before you leave.
Winter tires or chains: how the law treats each
The law treats them as equivalent. Real driving does not.
Winter tires | Snow chains | Snow socks | |
Legal on signed roads | Yes, if marked M+S or 3PMSF | Yes, if homologated and carried | Yes, if certified to the standards below |
Fitted when | All season, from the changeover | Only when snow or ice appears | Only when snow or ice appears |
Effort at the roadside | None | Cold hands, a learning curve | Lower, but still a stop |
Works on bare tarmac | Yes | No, they damage tires and road | No |
Best for | Planned mountain trips, long stays | Occasional, unexpected snow | Occasional snow, low-clearance cars |
Winter tires
The tires you use to satisfy the rule must be marked M+S, MS, M-S, M&S or 3PMSF, according to the Automobile Club of Livorno’s seasonal reminder. The 3PMSF symbol, a mountain with a snowflake, is the one that signals tested snow performance. The M+S letters alone are a manufacturer’s declaration about tread pattern, which is why many drivers prefer the snowflake.
Snow chains and snow socks
Chains must be homologated. According to ACI’s motoring guide, snow socks are treated as equivalent when they comply with UNI 11313 or ON V5121. If you buy anything at a roadside shop in a hurry, check for that certification on the packaging.
The police guidance is plain: you must carry chains on roads covered by the mandate if you do not have winter tires fitted. Carrying is the legal minimum; fitting them is what you do when the road demands it.
Do you need snow chains in Italy?
Only if your car is not already on winter tires and you drive on a road where the obligation applies. Drive from Milan to the lakes on a clear January day on a motorway without the signs, and nobody will ask about chains. Drive up to a ski resort the same week and the signs will tell you what applies.
That is why the question has no single national answer. The practical rule is simple: if your itinerary touches the mountains between November 15 and April 15, treat the equipment as mandatory and sort it out before departure. In the shoulder weeks, the US Army’s Italy winter safety guidance notes that local ordinances may bring the period forward or extend it, so a road in a high valley can require equipment earlier in autumn or later in spring than the national dates suggest.
Fines and what happens at a checkpoint
Outside built-up areas, the fine for lacking the required equipment is €85, according to the State Police. The more disruptive consequence is that failure to comply may result in an order not to continue the journey. On a mountain road that means a stranded car, a rearranged day and often a tow or taxi, which costs far more than any fine.
For a visitor in a rental car, there is another layer: the contract. Rental agreements generally make the driver responsible for fines and for damage that follows from misuse. Our guide to luxury car rental insurance explains how cover and driver responsibility fit together.
Two wheels or four?
The law asks for winter tires, or devices on at least the drive wheels. The Ministry, however, strongly recommends fitting winter tires on all four wheels rather than only the drive axle, to achieve uniform grip.
The reasoning is easy to picture. If only the front tires bite, the rear can step out on a descent. If only the rear tires bite, the car will not turn in. A balanced set keeps the car predictable. The same principle of matching rubber to conditions runs through any discussion of highway versus all-terrain tyres: the tire is the only part of the car that touches the road, so its design shapes everything else.
Chains follow a different logic. Because they go on the drive wheels only, the car is still asymmetrical in grip. That is legal and workable at low speed, but it is a reason to drive slowly and brake early.
Can winter tires be used in summer?
Yes, with one condition. The Italian highway code does not ban winter tires in summer; it speaks only about speed codes, as DriveK explains. During the winter period, November 15 to April 15, the code allows a derogation that lets winter tires carry a lower speed rating than your registration document specifies. Outside it, the tire’s speed rating must meet the one on the document.
A guide for drivers describes a changeover tolerance of about a month on either side, with winter tires allowed from October 15 and lower-rated ones to be removed by May 15. Treat that as a practical rule of thumb and check the current text if you plan to keep winter tires on late. For anyone driving a powerful car, this matters: winter tires rated lower than the car’s top speed are a seasonal compromise, not a year-round solution.
Winter driving in a luxury or high-performance car
Most of this article applies to any car. A few points apply with extra force when the car is a Ferrari, a Lamborghini or a Maserati.
Tire type. Many high-performance cars are delivered on summer performance tires, which stiffen and lose grip in cold temperatures even without snow. Whether a given car is on winter tires is something to confirm for that car and those dates.
Chain clearance. Low-profile bodywork leaves little room around the wheel. Not every sports car can take chains at all, which is a reason to prefer winter tires or a different model for mountain trips.
Drive layout. Rear-wheel-drive cars need the equipment at the rear, all-wheel-drive cars follow the manufacturer’s manual. Fitting chains in the wrong place is the same as not fitting them.
Choosing the right car. For a snowy itinerary, a grand tourer or an SUV is often the better answer. Our comparison of the Maserati Levante and Range Rover covers two luxury SUVs that suit Alpine roads.
This is not an argument against driving a supercar in Italy. It is an argument for matching the car to the season: a Ferrari on the Amalfi coast in spring, a more composed all-wheel-drive car for a February run to Cortina or Courmayeur.
What to confirm before you rent
Tires are part of the contract, and it pays to treat them that way. One example from the public sector shows the principle: in one long-term rental specification published by ACI Informatica, the base service includes both summer and winter tire sets and the seasonal replacement. A well-run rental treats tires as a defined service rather than an afterthought. Ask the same of yours.
Before you confirm any winter booking, get answers to these:
Which tires are on the car for my dates? Ask for the marking (M+S or 3PMSF) and the season.
Are chains or certified snow socks in the car? If yes, check they fit that specific wheel size, and ask whether the car is allowed to use them.
Can I take the car into the mountains? Some rental terms restrict snow, ice or specific roads.
Who is responsible for a fine or tow? Read the clause, then compare it with your insurance.
Can the car be swapped? If the forecast changes, a more suitable model may be the smart move.

Our perspective
We hear one assumption more than any other from guests planning a winter trip: that a premium car arrives ready for every road. It does not, and we would rather say so before you book than at a mountain checkpoint.
The way we see it, winter equipment belongs in the same conversation as the model, the route and the delivery address. A car that suits a lakeside weekend in April may not suit a pass in January, and the right answer is to choose the car for the journey rather than force the journey around the car. That is why we work from your itinerary: where you are going, which days, how many people, how much luggage. From there we recommend a model, and we guarantee that the model you book is the model you receive.
Our practical advice for winter guests is short. Name the mountain destinations in your first message. Ask for the tire and chain situation of the specific car in writing. If your plan is mostly snow, choose an all-wheel-drive grand tourer or SUV over a low-slung sports car. And if the weather turns, tell us early, because a swap is easier to arrange before departure than at the roadside.

A simple checklist for a winter drive in Italy
Whatever you drive, run through this the day before you leave:
Check the dates: are you travelling between November 15 and April 15, or in the weeks around it?
Check the route for signed sections, and look for local ordinances covering the valleys you will use.
Confirm the tire marking on the car: M+S or 3PMSF.
If the car has no winter tires, confirm the chains or snow socks are in the trunk and fit the wheels.
Practice fitting them once, in daylight, on dry ground, before you need them.
Keep gloves, a torch and a warm layer within reach, not buried under the luggage.
Plan your fuel and charging stops, since mountain stretches are long and cold air is hard on range.
Leave early. Winter roads reward patience, and a calm start makes the whole day feel like a private escape rather than a race.
Fitting chains is a ten-minute job when you have practiced and a forty-minute one when you have not. The cheapest insurance against a bad morning is rehearsal.
FAQ
Are snow chains required in Italy?
They are required only if your car does not have winter tires and you are on a road signed with the winter equipment obligation. In that case you must carry homologated chains, or certified snow socks, between November 15 and April 15. Local ordinances can extend those dates.
What is better, snow chains or snow socks?
Both are legal when certified, with snow socks needing to meet UNI 11313 or ON V5121. Socks are lighter and easier to fit, while chains tend to cope better with deep snow and steep gradients. If your car has little wheel-arch clearance, check what the manufacturer allows first.
Do I need winter tires on two wheels or all four?
The law requires winter tires, or anti-skid devices on at least the drive wheels. The Ministry of Infrastructure and Transport nevertheless strongly recommends winter tires on all four wheels for uniform grip. A mixed setup can make the car unstable on snow.
Can I use winter tires in summer in Italy?
There is no ban, but the tire’s speed rating must meet the one on your registration document outside the winter derogation. Lower-rated winter tires are for the cold months only. They also wear faster and brake less sharply on hot tarmac.
Does a rental car in Italy come with winter tires?
Not automatically, and it depends on the car, the dates and the contract. Ask for the tire marking and the chain situation for your exact vehicle before you confirm, and get the answer in writing.
