Tire studs, specifically metal studs, are prohibited in several states across the United States. These regulations are primarily in place to minimize road damage that studs can cause, particularly on dry pavement.
States Where Metal Tire Studs Are Illegal
Metal studs are generally prohibited in 11 states. While some states have outright bans, others may allow alternative forms like rubber studs or have county-specific exceptions.
The states where metal studs are illegal include:
- Alabama
- Florida
- Hawaii
- Illinois
- Louisiana
- Maryland
- Michigan
- Minnesota
- Mississippi
- Texas
- Wisconsin
Specific Regulations and Exceptions
It's important to note that the rules can have nuances:
- Rubber Studs: Some states that prohibit metal studs may still allow tires equipped with rubber studs, as these are less abrasive to road surfaces.
- Maryland Exception: In Maryland, the legality of tire studs can vary by county. This means studs might be permitted in certain counties while being illegal in others. Drivers should verify local regulations.

Why Are Tire Studs Restricted?
The primary reason states restrict or ban tire studs is their potential to cause wear and tear on road surfaces, especially when there's no snow or ice. On dry pavement, metal studs can:
- Damage Roads: Accelerate rutting and cracking of asphalt and concrete.
- Reduce Pavement Life: Lead to higher maintenance costs for state transportation departments.
- Generate Noise: Create increased road noise.
For these reasons, many states that experience less severe winter conditions or have significant stretches of dry roads during winter opt to prohibit metal studded tires. Drivers in these states often rely on studless winter tires, which offer excellent traction in snow and ice without the road-damaging effects of metal studs, or all-season tires depending on local conditions.
