The first snow has already settled on the roadsides, nightly frosts have turned the asphalt into an ice rink, and a multi-ton road train confidently moves along the highway — without noticeable signs of seasonal "re-shoeing." At the same time, passenger car owners have long changed their summer tires to winter ones. Against this background, a natural bewilderment arises: why do different rules seem to apply to heavy trucks?
In fact, there is no disregard for safety here. The answer lies in a complex interplay of economic calculations, legal norms, and the real operating conditions of long-haul vehicles. Fleet owners and truckers themselves are forced to constantly balance between traffic safety, the profitability of trips, and the harsh realities of the logistics business.
Do Trucks Have Real Winter Tires?
Yes, such tires exist and have been mass-produced for a long time. This is not an exotic item or a marketing gimmick, but a full-fledged product of the world's largest manufacturers. In their design, they differ significantly from summer versions. They use a special rubber compound that does not "harden" at low temperatures, and the tread has a developed pattern with deep sipes designed to work on snow and ice.
There are entire specialized lines on the market. Bridgestone has the M726 EL model, designed for drive axles. Michelin offers X Ice Snow tires for tractors and the X Multi series for trailer equipment. Continental produces the ContiWinter line, and Goodyear has UltraGrip Max. Russian manufacturers also do not stand aside: Cordiant SnowCross CT-1 and "Kama" NR-202 are available for sale.
At the same time, it is important to consider one fundamental point. The designation M+S ("mud and snow") does not in itself mean that the tire is a full-fledged winter tire. Confirmation of real winter characteristics is the symbol of a mountain peak with a snowflake — the 3PMSF marking, which is received only by tires that have passed special tests.
Why Do Trucks Often Drive in Winter Without "Winter" Tires?
The refusal to change tires seasonally is almost never spontaneous. As a rule, this is the result of a combination of several factors at once.
The Legal Aspect
From a legal point of view, the situation for trucks differs from the rules for passenger cars. In accordance with the Technical Regulations of the Customs Union TR CU 018/2011 and Government Decree No. 837, there is no direct requirement for the mandatory use of winter tires for freight vehicles of categories N2 and N3. Since November 2018, such vehicles are allowed to be operated on suitable tires all year round. This removes the legal obligation from carriers to change tires seasonally.
Economics That Decides Everything
The financial component is the main argument against the widespread installation of winter tires.
The cost of one winter tire for a tractor can easily exceed 40,000 rubles. A full set for a tractor and trailer costs from 300,000 to 1,000,000 rubles. For a fleet of dozens of vehicles, such investments turn into a serious burden on the budget.
Indirect costs are added to direct costs. The question arises of storing a second set of 12–16 wheels, paying for tire fitting and forced downtime of equipment. While the truck is at the service station, it does not earn — only the trip brings income.
There is another nuance. If a truck spends most of its time moving along cleared federal highways, soft winter tires on dry asphalt wear out at an accelerated rate. The loss of resource can reach 30%, and for southern regions, such a replacement often turns out to be economically meaningless.
Specifics of Operation and the Mass Factor
The multi-ton weight of the truck plays its role. Due to the large load on the axle, the truck literally pushes through snow slush and ice, providing an acceptable level of grip even on reinforced all-season tires.
In addition, long-distance routes most often run along highways that are cleaned and treated first. Many drivers note that for a significant part of the winter season they have to drive on dry or almost dry asphalt.
In really difficult conditions, snow chains come to the rescue. On ice and steep climbs, they are often more effective than any studs, so they are used on passes and in high-risk areas.
Climate and Tire Shortage
Russia is characterized by a huge variety of climatic conditions. In the Krasnodar Territory, winter tires for trucks are often simply not needed, while in Siberia or the Urals, this issue is approached much more strictly. Availability also plays an additional role: in some regions it is not easy to quickly find the required number of high-quality winter tires of a specific size and brand.
What Professionals Say and What the Law Requires
Most experienced heavy vehicle drivers agree that reinforced all-season tires with M+S marking, taking into account the weight of the vehicle, are often sufficient for year-round operation.
At the same time, the requirements of the legislation for the condition of tires remain strict and mandatory at any time of the year. The residual tread depth must be at least 4 mm. It is forbidden to use tires of different sizes, designs or models on the same axle. If studded tires are used, they must be installed on all wheels.
There is also a separate important rule. In the winter period — from December to February — trucks not equipped with tires with 3PMSF marking must have snow chains on board. This requirement is enshrined in Government Decree No. 837 (paragraph 10.4).
When Winter Tires for a Truck Are Really Necessary
Despite all the economic logic, there are situations in which the installation of winter tires is justified and even critical. This refers to regular work in the northern regions, in the Urals and in Siberia, where snowfalls and ice are commonplace. The same applies to the transportation of particularly valuable or dangerous goods, when the risk of an accident is disproportionately higher than the cost of a set of tires.
Winter tires also become a significant advantage on routes with mountain roads and passes, where traction on ascents and descents comes to the fore. Finally, companies that regularly miss deadlines or get stuck on the roads due to saving on tires quickly lose customer trust and business reputation.
How to extend the life of truck tires
Regardless of the type of tire, its service life directly depends on operation. Maintaining the recommended pressure is a key factor, and a TPMS system that transmits data from each wheel directly to the cab can help here. Regular rotation and balancing, performed every 20–30 thousand kilometers, ensures even wear.
It is equally important to observe the load index: overload leads to overheating and destruction of the frame. A smooth driving style without sudden accelerations and braking also noticeably prolongs the life of the tread. The combination of these measures allows you to increase the mileage of one set of tires from a typical 80,000 to 120,000 kilometers, providing significant savings.
Calculation instead of a formal approach
The situation with winter tires for trucks is not ignoring the rules, but the result of a cold and pragmatic calculation. Fleet owners analyze routes, climatic conditions and financial indicators. For most long-distance and international transportation on major highways, it is more rational to use high-quality all-season tires, having chains in case of force majeure.
At the same time, for regions with severe winters and for specialized transportation, professional winter tires remain not an expense, but an investment in safety, operational stability and business reputation.
