Yes, studded tires are legal in Minnesota but subject to strict seasonal and regional restrictions enforced by the Minnesota Department of Transportation (MnDOT). State statutes permit studded tires from October 1 to April 30, aligning with winter road conditions, while prohibiting their use outside this window to mitigate pavement damage. Local ordinances in urban areas like Minneapolis and St. Paul may impose additional limitations, particularly in designated noise-sensitive zones.
Key Regulations for Studded Tires in Minnesota
- Seasonal Window: MnDOT mandates studded tire use only between October 1 and April 30, with exceptions for emergency vehicles or commercial fleets operating under special permits.
- Stud Specifications: Tires must comply with Federal Motor Vehicle Safety Standards (FMVSS 119), limiting stud protrusion to 1/16 inch (1.5 mm) to reduce road wear.
- Local Restrictions: Cities like Minneapolis enforce noise ordinances (e.g., <88 decibels at 50 feet) during non-winter months, effectively banning studded tires in residential areas year-round.
MnDOT’s 2026 compliance framework introduces mandatory tire registration for commercial vehicles using studded tires, aiming to track usage and enforce penalties for violations. Violations incur fines up to $1,000 under Minnesota Statutes §169.725, with repeat offenses triggering vehicle impoundment. Drivers should verify local ordinances, as county-specific rules (e.g., Dakota County’s winter traction requirements) may supersede state guidelines.
