What the studded tire law says in Pennsylvania
The core rule, the season window if there is one, and who the law exempts.
| What the law says | What it means |
|---|---|
| Legal November 1 to April 15 | 75 Pa. Cons. Stat. § 4525(c) permits tires fitted with ice grips or tire studs between November 1 of each year and April 15 of the following year. Any use of studs contrary to that window is unlawful under the same subsection. |
| Projection limited to two thirty-seconds of an inch | The studs may project no more than two thirty-seconds of an inch beyond the tread of the traction surface of the tire. The PennDOT regulation at 67 Pa. Code § 175.65(f) repeats the same figure for passenger cars and light trucks. |
| Tire chains only in an emergency | 75 Pa. Cons. Stat. § 4525(d) lets tire chains be used temporarily during a period of snow and ice emergency if they conform to PennDOT regulations. Chains are tied to the emergency, not to the November to April window. |
| Who is exempt | What it means |
|---|---|
| Extension by executive order | Under 75 Pa. Cons. Stat. § 4525(c) the Governor may by executive order extend the time studs may be used when highway conditions make the tires a safety factor. The April 15 end date can move, but only by that order and only outward. |
| Antique vehicles | 67 Pa. Code § 175.65(e) lets an antique vehicle run non-pneumatic tires if the manufacturer originally equipped it that way. That is a tire-type allowance and not a stud exception. |
What you can do right now
Concrete, neutral steps for running studded tires within the law in Pennsylvania. This is legal information, not legal advice.
- Fit studs no earlier than November 1
Install ice grips or tire studs at the start of the window and plan to run them through winter inside the November 1 to April 15 season.
- Have them off by April 15
Take the studs off before April 16, when the escalating out-of-season fine begins. Waiting until summer raises the penalty band by band.
- Keep chains for emergencies only
Tire chains may be used temporarily during a snow and ice emergency under 75 Pa. Cons. Stat. § 4525(d). They are a storm measure, not a substitute for the studded-tire season.
If you were cited over studded tires, a local traffic attorney or public defender can explain how the charge is handled and whether an exemption applies to you.

What drivers in Pennsylvania get wrong about studded tires
Pennsylvania draws a hard calendar around studded tires. 75 Pa. Cons. Stat. § 4525(c) permits tires fitted with ice grips or tire studs of wear resisting material only between November 1 of each year and April 15 of the following year, and it calls any use outside that window unlawful. Inside the season the studs may project no more than two thirty-seconds of an inch beyond the tread, a figure the PennDOT regulation at 67 Pa. Code § 175.65(f) repeats. What makes Pennsylvania distinct is the penalty. Section 4525(e)(2) escalates the out-of-season fine month by month, $35 from April 16 to May 31, $45 in June, and $55 from July through October, so the cost of forgetting to remove studs grows as summer wears on. The Governor may push the April 15 end date outward by executive order when conditions warrant, and tire chains stay available during a snow and ice emergency under § 4525(d). Fit studs in November, pull them by April 15, and a Pennsylvania driver stays clear of a summary offense.
