Missouri Studded Tire Law
Studs are legal November 1 to March 31. Metal or carbide studs are barred April 1 to November 1 (RSMo 307.171), and no GVW cap keeps them off your truck. Run them off-season and it's an infraction. The statute date is the enforced date; there's no separate removal-deadline gap to watch. Missouri has no statute scheduling or restricting tire chains, so chains aren't barred when winter conditions require them; a stud is not a chain.

The window and winter-tire rules
- Season: November 1 to March 31. Metal or carbide studs are barred April 1 to November 1 (RSMo 307.171).
- No M+S or 3PMSF winter-tire mandate. Missouri sets no tire-chain season or restriction by statute; chains aren't barred and are used when snow or ice requires. In-season studs are an equipment allowance, not a chain. See the Missouri tire-chain page.
