Studded Tires Allowed Only From November 1 Through April 15

The controlling section is R.C. 5589.081, and where it sits in the code explains its shape. Ohio put the studded-tire rule in Title 55, Roads-Highways-Bridges, Chapter 5589, Offenses Relating to Highways, rather than in Chapter 4513, where nearly every other Ohio vehicle-equipment requirement lives. It is drafted as an offence against the pavement rather than as a safety-equipment standard, which is why its two carve-outs are for public safety vehicles and school buses and not for bad weather. The section has been in its current form since August 22, 2008, when S.B. 44 of the 127th General Assembly added the retractable-stud provision.

The definition is broader than metal studs. Division (A) reaches any tire equipped with metal studs or studs of wear-resisting material that project beyond the tread of the traction surface of the tire. Ceramic, hardened polymer and carbide studs are all caught, because the test is projection beyond the tread surface and not the material. Division (A) also borrows the terms motor vehicle, street or highway, public safety vehicle and school bus from R.C. 4511.01, so the definitions used for ordinary Ohio traffic law apply here without modification.

The retractable-stud allowance in division (B)(2) is the practical escape valve. A driver may run retractable studded tires with the studs retracted at any time of the year, and only has to keep the studs extended inside the November 1 to April 15 window. That means the tires do not have to come off the vehicle in spring, which is not true of fixed studs: a fixed-stud tire still on the car on April 16 puts the driver in violation the moment the vehicle moves on a street or highway.

Division (C) removes tire chains from the section altogether, but only conditionally. Chains are outside the rule when there is snow or ice on the streets or highways where the chains are being used, or in the immediate vicinity. Ohio therefore runs two different tests side by side: studs are governed by the calendar and chains by the actual road surface. Chains fitted on a dry April road get no protection from division (C).

A separate and much older section, R.C. 5589.08, bans a different class of traction device outright with no seasonal window at all. It prohibits driving a traction engine or tractor over the improved highways of the state on tires or wheels equipped with ice picks, spuds, spikes, chains, or other projections of any kind extending beyond the cleats, and it also prohibits towing or pulling a vehicle whose tires carry such projections. Anyone hauling farm equipment in Ohio needs to read that section alongside the studded-tire window.

R.C. 5589.081 contains no clause preserving or displacing local authority, in contrast with R.C. 4511.214(D), which expressly lets an Ohio local authority adopt more stringent rules for certain classes of vehicle. The dates in the section are the operative ones statewide, and they do not shift with a late winter: the window closes on April 15 in Cleveland and in Cincinnati alike.

C. C. 99(B), which groups it with the other Chapter 5589 highway offences. C. C. 24 authorises a jail term only for misdemeanors of the first through fourth degree, so no jail is available for this offence. There is no licence suspension written into the section. C. 99(B) sets a flat minor misdemeanor no matter how many prior citations the driver holds. Enforcement is by the State Highway Patrol on state routes and interstates and by municipal police and county sheriffs elsewhere, normally as a roadside traffic citation. C. 02(B)(1), which lists tires among the items examined when a trooper directs a driver to submit the vehicle to an inspection.
