Studded tires improve traction on icy and snowy roads. Pennsylvania, like most states, allows the use of these tires with certain restrictions. Current laws permitting the use of studded tires date back to 1983.

Studded Tires

In Pennsylvania, studded tires are currently allowed for road use from November 1 to April 15. However, Pennsylvania code § 175.145 also limits the studs, stating they may not have "projections exceeding 2/32 inch beyond the tread of the traction surface of the tire." The governor of Pennsylvania may, at his discretion, waive the deadline in case of an early or late snowstorm.


Driving with studded ties after April 15 and before November 1 may result in a ticket and fine. The amount varies and may depend on the month involved, with fines steadily rising through the warmer months. Even travelers passing through Pennsylvania may not use studded tires outside the permissible dates.


Pennsylvania has alternately allowed, then later forbidden, the use of studded tires. During the 1970s studded tires were first permitted, then outlawed, due to concerns about the damage caused to the roadways.
