Some local drivers get a two-week extension on the deadline to change out studded tires.

Alaskans living south of 60 degrees north latitude have until Sunday, April 15 to switch out their studded tires, according to an Alaska State Trooper press release.

Those who drive on any portion of the Sterling Highway, however, have until May 1 to remove them.

Latitude 60 crosses Alaska from east to west just south of Prince William Sound, Seward, and Chefornak.

Alaskans living north of the 60-degree line have until the end of April to remove studded snow tires.

“While studded snow tires can provide a level of certainty for drivers during winter months, they cause additional wear and tear on paved Alaska roads,” State of Alaska Department of Public Safety Commissioner Walt Monegan said in the release. “Winter driving conditions no longer impact the portion of the State south of 60° North Latitude, and Alaskans in those areas should make arrangements to have their studded tires removed.”
