Ukrainian legislation does not contain a direct ban on the use of winter tires in the warm season. Therefore, strictly speaking, there is no penalty for merely having winter tires in summer. However, there are important nuances.
When the tread is worn below the permissible level (for passenger cars, this threshold is 1.6 mm), patrol officers have legal grounds to impose a fine of 340 hryvnias, guided by Part 1 of Article 121 of the Code of Ukraine on Administrative Offenses. If the condition of the wheels poses an obvious danger to traffic, the inspector may decide to prohibit further operation of the vehicle.
Why are winter tires dangerous in summer?
Winter tires are designed to work in low-temperature conditions. Their rubber compound is softer, which provides reliable grip on cold or icy surfaces. However, in summer, this feature turns into a significant drawback. In heat, the material becomes even softer, which leads to:
-
noticeably longer braking distances, especially on hot asphalt,
-
worse vehicle stability during maneuvers,
-
weaker grip on wet surfaces,
-
a higher risk of aquaplaning,
-
accelerated wear of the tires themselves.
All this not only worsens the level of safety but also negatively affects the comfort and handling of the car.
Is it really a saving?
A common opinion goes like this: "Why spend money on summer tires if the winter ones are not worn out yet?" It seems reasonable. But in reality, this is a deceptive benefit.
In summer, winter tires wear out much more intensively, so by the next cold season, they will most likely become unusable. Then you will still have to buy a new set. In addition, due to the increased rolling resistance of soft rubber, fuel consumption rises. In the end, costs only increase, while the level of safety decreases.
What about all-season tires?
Such tires have a right to exist, but with certain caveats. All-season tires are always a compromise: they do not provide the same confidence on ice as winter tires, nor the same stability in heat as summer tires. For regions with a mild climate and mostly city driving, this may be an acceptable option. However, for intensive use and frequent trips outside the city, it is better to have two separate sets for the seasons.
Practical recommendations
-
Switch to summer tires when the average daily temperature consistently stays above 7°C.
-
Regularly check the tread depth — it should not be less than 1.6 mm.
-
Do not delay changing tires — emergency braking in summer on overly soft rubber can lead to an accident.
-
Follow the rules for storing seasonal tires: a dry, cool place, protected from direct sunlight.
Summary
Driving on winter tires in summer is not a violation of the law, but it contradicts common sense. This approach threatens not only safety but also hits the wallet: braking and stability worsen, fuel consumption increases, and the tires themselves wear out faster.
