When do winter tires become mandatory in Romania and what are the costs

Winter tires are mandatory in Romania when roads are covered in snow, ice, or frost. Drivers face fines and vehicle registration confiscation if they don't comply with these conditions. Drivers are advised to switch to winter tires when temperatures consistently drop below 7°C for better safety and shorter braking distances. Prices for a set of four winter tires in 2025 range from approximately 600 RON for budget options to over 3,000 RON for premium brands and large sizes. Winter tires must be marked with "M+S," "M.S.," or "M&S." Prices have increased by 5-8% on average compared to last year, with premium brands seeing the largest hikes.
