Are you properly maintaining your winter tires? Tread depth is crucial during the winter season, as the depth of the grooves determines the effectiveness of evacuating snow, slush, and water from under the wheels. The deeper the tread, the better the traction on slippery surfaces and the shorter the braking distance in challenging weather conditions. In practice, winter tires should have at least 4 mm of tread to maintain their traction and stability in snow. Shallower tread not only increases the risk of skidding but also impairs vehicle handling in low temperatures. Therefore, drivers should regularly check their winter tires (tread depth).
The minimum tire tread depth in Poland is 1.6 mm, which applies to both summer and winter tires . However, this is a limit that no longer provides adequate safety. Below this level, the tire loses its ability to effectively evacuate water, increasing the risk of aquaplaning and extending braking distances. For trucks and heavy-duty machinery, worn tread also means reduced stability and increased fuel consumption. For this reason, experts recommend replacing tires well before the minimum tread depth is reached.
Permissible tire tread depth refers to the condition in which a tire still meets legal requirements but does not necessarily guarantee the best driving characteristics. Although regulations permit driving with a tread depth of 1.6 mm, in practice, comfort, traction, and braking performance are significantly reduced. In trucks and construction machinery , tread depth that is too shallow can lead to skidding, uneven wear, and increased stress on the drivetrain . Regular inspection allows you to plan replacement at the optimal time, before the permissible tire tread depth drops to a critical level.
Winter tire tread depth is even more important for trucks than for passenger cars, as the weight of the vehicle and the cargo it carries significantly impacts the tire's road performance. Deep tread helps maintain traction on snow and ice, which is crucial when braking and starting uphill. Too shallow tread increases the risk of wheel spin and loss of control. In professional transport, winter tires are recommended to have significantly more than the legal minimum , highlighting the importance of winter tire tread depth.
Minimum tire tread depth is one of the first parameters checked during a roadside inspection, especially for trucks. Exceeding the allowable minimum can result in a fine, suspension of the vehicle's registration certificate, or even immobilization of the vehicle until the tires are replaced. For transport companies, this means not only costs but also downtime and delays in order fulfillment. Regular tread depth checks and maintaining documentation of tire condition are the best way to avoid problems related to minimum tire tread depth.
Tire tread depth directly impacts the safety of the entire fleet, so transport managers should monitor tire wear on a regular basis. Replacing tires before they reach their limits improves stability, shortens braking distances, and reduces the risk of accidents . It also reduces operating costs, as worn tires generate greater rolling resistance and increase fuel consumption. Proper tire management helps maintain tire tread depth at a level that ensures maximum efficiency and safety.
You already know the allowable tread depth for your tires. AUTOS offers a wide selection of tires for vehicles and work machinery, including specialized construction tires and professional truck tires , suited to various operating conditions and loads. We also offer rims, mounting accessories, and technical support to help you choose the right tires for your specific application. This allows transport and construction companies to keep their vehicles fully operational and compliant with regulations.
Both tire tread depth, minimum tread depth, and permissible tire tread depth have a direct impact on traction, braking distance, and driving stability. Regular tire inspection and timely tire replacement help avoid fines, breakdowns, and dangerous situations on the road . Maintaining proper tread condition is an investment in the safety of the driver, cargo, and the entire fleet.
