Maine Studded Tire Law
Metal studs are barred May 1 to October 1, so you run them roughly October 1 to April 30 (29-A M.R.S. §1919). Retractable studs can stay mounted year-round but can't be engaged in the off-season, and the DOT Commissioner can extend the window or issue a permit. No GVW cap, so the season binds a loaded truck. No winter-tire mandate, and studs aren't chains.

The window and winter-tire rules
- Season: About October 1 to April 30 (metal studs barred May 1 to October 1 — 29-A M.R.S. §1919)
- Maine sets no winter-tire mandate. Studs are equipment, not chains — legal in-season studs don't clear a chains-required order. See the Maine chain-law page for storm requirements.
