The snow has melted, the roads are dry and the studded tires are still on the car. Maybe the shop is booked for two weeks, maybe you were hoping to squeeze one more season of tread out of them or maybe you just never got around to it. Either way, the question is the same: is it actually a problem to keep driving on studs once winter is over?
In many states it is a legal problem with a specific deadline and a fine attached. In every state, it is a practical problem. Studs that claw into ice do the opposite of what you want on warm, bare pavement: they reduce grip, chew up the road, wear out fast and make a lot of noise. Here is what the law says, why the rules exist and what happens to your tires and your car if you leave them on.

The Short Answer
In states with a stud season, driving on studded tires outside the permitted dates is illegal and can earn you a ticket. Where studs are allowed year-round, you will not be breaking the law, but you will be paying for it in tire wear, reduced traction on dry and wet pavement, extra road noise and damage to roads that every taxpayer helps fix. The sensible plan everywhere is the same: get the studs off once the risk of ice has passed.
What Studs Do and Why They Only Make Sense in Winter
A studded tire is a winter tire with small metal pins, typically tipped with tungsten carbide, set into the tread. Each pin protrudes slightly from the rubber. On glare ice, those tips dig into the surface and give the tire something to bite, which shortens braking distances and improves control in exactly the conditions where ordinary rubber struggles most.
That advantage is narrow. A review of studded tire research by the Oregon Department of Transportation found that studs show their benefit on clear ice near the freezing mark, while non-studded winter tires function as well, if not better, in almost all other winter situations. Once the ice is gone, the studs stop helping and start causing problems.
When Studded Tires Are Legal
There is no national rule. Each state sets its own approach, and they fall into three broad groups: seasonal windows, outright bans with narrow exceptions and year-round permission.
Seasonal Windows: Some Verified Examples
Most states that allow studs restrict them to a winter window. A few well-documented examples:
| State | Permitted Season | Notes |
|---|---|---|
| Washington | November 1 through March 31 | WSDOT sets a $137 penalty for running studs after the deadline |
| Oregon | November 1 through March 31 | ODOT may extend the season only when weather conditions require it |
| New York | October 16 through April 30 | Dates published by the New York DMV |
| Alaska | Varies by latitude | Later start and earlier end south of the 60th parallel than north of it |
Washington is a useful case study in how strictly these deadlines are enforced. WSDOT says there are no individual exceptions or out-of-state waivers to the March 31 deadline. State law allows the agency to extend the season statewide if weather warrants, but an extension is the exception, not the rule.
Many other states with snowy winters use similar windows that typically open in October or November and close between late March and the end of April. The exact dates, the allowed stud protrusion and the penalty vary, and legislatures change them from time to time. Treat any list you find, including this one, as a starting point and confirm the current rule with your state’s DMV or transportation department before you plan your swap.
States That Ban Studs
A handful of states restrict studded tires almost entirely. Minnesota, for example, prohibits tires with studs or similar metal protrusions for ordinary passenger use, with narrow exceptions. Wisconsin and Michigan also restrict studs heavily. In those states, the question of summer use does not really arise, because the tires are not permitted for most drivers at any time of year. If you are traveling from a stud-friendly state into one of these, check the rules for nonresident vehicles before you go.
States With Few or No Date Limits
Some states, Colorado among them, allow studded tires without a seasonal window. That is a legal answer, not a recommendation. Everything below about wear, grip, noise and road damage still applies in July whether or not a law forbids it.
Stud deadlines are set by the calendar, not the weather. If the forecast shows a late-season storm after your state’s cutoff, plan on traction tires or chains rather than counting on an extension.
The Fine Is the Smallest Problem
A ticket is the most visible consequence, but it is not the most expensive one. The bigger costs come from what studs do to the road, to your tires and to your car’s grip on bare pavement.
Damage to the Road
Every time a stud strikes bare pavement, it dislodges a tiny amount of material. Multiply that by millions of tire passes and the result is the pair of grooves you see worn into the wheel paths of many northern highways. Pavement Interactive, a pavement engineering reference, cites a rule of thumb of about 0.1 inch of wheel path wear per million studded tire passes.
The bills are large. WSDOT estimates that studded tires cause between $20 million and $29 million in damage to Washington’s state-owned roads each winter, before counting city and county streets. Oregon’s own estimate for 2015 was just over $8.5 million, and Alaska’s transportation department found that studs shortened the life of asphalt by roughly seven years.
Those ruts are a safety problem as well as a budget problem. They fill with water and ice, which creates spray and raises the risk of hydroplaning for every driver on the road, studded or not. Running studs in summer adds months of wear to that damage with none of the winter traction benefit to justify it.
Less Grip on Warm, Bare Pavement
Studs need a soft, icy surface to dig into. On dry asphalt or concrete, the metal pins hold part of the tread slightly off the road and contact the pavement with hard metal instead of rubber. Pavement engineering research notes that studded tires may offer no safety advantage over modern winter tires in non-icy conditions and that studs may actually decrease tire-road friction there. ODOT has likewise pointed to research showing that studless traction tires provide better traction than studded tires on bare pavement.
The tire’s rubber compounds work against you too. Winter tread compounds are formulated to stay flexible in the cold. In summer heat, that soft rubber squirms and deflects more, which dulls steering response and lengthens stopping distances compared with a tire built for warm weather. Combine metal pins on hot pavement with a compound that is out of its element, and braking and cornering both suffer when you need them most.
Faster Wear and Lost Studs
Heat and dry pavement are hard on studded tires. The soft winter compound wears quickly on warm asphalt, and as the rubber around each stud wears down, the pins can loosen and fall out. A tire that loses studs over the summer comes back next winter with less of the ice grip you bought it for. Summer driving also burns through tread depth that you need for slush and snow, which shortens the useful life of an expensive set of tires.
Noise
Metal pins on bare pavement produce a constant clicking and whirring that is hard to ignore. Inside the car, it adds to cabin noise on every trip. Outside, it adds to traffic noise for people living along busy roads. On an icy road, that noise is a fair trade for traction. In June it buys you nothing.
Studded Tires on Bare Pavement at a Glance
| Factor | Effect of Summer Use |
|---|---|
| Legality | Illegal after the deadline in states with a stud season, with fines that vary by state |
| Road damage | Wears ruts into the pavement that fill with water and raise hydroplaning risk |
| Dry and wet grip | Studs and a soft winter compound reduce traction on warm, bare pavement |
| Tire wear | Winter rubber wears quickly in heat, and studs can loosen and fall out |
| Noise | Constant clicking and whirring inside and outside the car |
| Winter readiness | Less tread and fewer studs left for the next season |
Swapping Out and Storing Your Studs
The fix is to change tires as soon as the ice risk has passed and before your state’s deadline. A few practical steps make the swap smoother and keep the studded set ready for next winter.
- Book the appointment early. Shops fill up in the final weeks before a deadline, and an extension is never guaranteed.
- Install warm-weather tires suited to how you drive, whether all-season, all-weather or summer performance tires.
- Clean the studded tires and let them dry completely before storing them.
- Mark each tire’s position so they can be rotated when you reinstall them.
- Store the tires in bags or totes in a cool, dry, dark place, away from motors, furnaces and other ozone sources.
- Before the next season, inspect the tread and look for missing or worn studs, cracks and bulges.
Consider a Studless Alternative
If the deadline crunch and summer temptation sound familiar, think about whether you need studs at all. Modern studless winter tires carry the three-peak mountain snowflake symbol and offer strong grip on snow and ice without damaging the road. WSDOT recommends them as an effective substitute for studs, and they have no legal season in most states. For drivers in areas where clear ice is occasional rather than routine, a studless winter tire may cover winter well without the spring scramble.
Frequently Asked Questions
In many states, yes. Where a stud season exists, such as Washington, Oregon and New York, driving on studs after the closing date is a violation that can bring a fine. A few states ban studs for most drivers at any time of year, and some allow them year-round. Check your state’s current rules before you plan your swap.
Penalties vary by state. In Washington, WSDOT puts the penalty at $137 for driving on studded tires after March 31. Other states set their own amounts, so look up the figure for the state where you drive.
Not well. Studs need ice to dig into, and on bare pavement they can reduce friction rather than increase it. Research summarized by transportation agencies shows studless traction tires provide better grip than studded tires on bare pavement.
It wears them out quickly. The soft winter compound breaks down faster in the heat, and as the rubber wears, studs can loosen and fall out. You end up with less tread and fewer studs for the next winter, which is when you actually need them.
Individual extensions generally do not exist. Some states, Washington and Oregon among them, can extend the season statewide when weather conditions call for it, but those decisions are announced by the transportation department and are not something a driver can count on.
The main reason is road damage. Studs wear ruts into the pavement that cost states millions of dollars a year to repair, and those ruts collect water and raise the risk of hydroplaning. Seasonal windows limit that damage to the months when studs provide a real safety benefit on ice.
The Bottom Line on Summer Studs
Studded tires are a narrow tool built for one job: biting into ice. Once that ice is gone, they lose their advantage and turn into a liability. On warm pavement they offer less grip than the right tire, wear quickly, shed studs, make constant noise and grind ruts into the road. In states with a stud season, keeping them on past the deadline also puts a ticket in play.
Know your state’s dates, schedule the swap ahead of the rush and store the studded set carefully so it is ready when the ice returns. If the spring changeover has become an annual headache, a modern studless winter tire may serve your winters well enough to make studs unnecessary.
