Yes, studded tires are legal in Wyoming, but their use is strictly regulated under state and federal guidelines. The Wyoming Department of Transportation (WYDOT) permits studded tires from November 1 to April 30, aligning with seasonal winter road conditions. Federal law restricts stud protrusion to 1/16 of an inch, and local ordinances in municipalities like Jackson Hole may impose additional seasonal restrictions to mitigate road damage.
Key Regulations for Studded Tires in Wyoming
- Seasonal Operation: WYDOT mandates studded tire use only from November 1 to April 30, with exceptions for emergency vehicles. Violations may result in fines under Wyoming Statute § 31-5-205.
- Stud Protrusion Limits: Federal Motor Vehicle Safety Standards (FMVSS 119) cap stud protrusion at 1/16 inch to minimize road surface damage. Non-compliant tires are prohibited year-round.
- Local Restrictions: Counties with high traffic volumes, such as Teton County, may enforce additional bans or permit requirements during peak winter months to protect asphalt infrastructure.
Wyoming’s regulations balance mobility with infrastructure preservation, reflecting input from WYDOT and the Federal Highway Administration. Motorists must verify local ordinances, as enforcement varies by jurisdiction. Non-residents using studded tires must adhere to the same seasonal and protrusion rules to avoid penalties.
