Flat tire in winter: what to do before roadside help arrives

A cold-weather flat-tire checklist for safe positioning, service details and deciding between a mobile wheel change and towing.

Updated September 28, 2026

Get the vehicle into the safest practical position

A flat tire on a snowy shoulder is first a traffic and exposure problem. If the vehicle can be moved safely to a parking lot or other protected location without causing more damage, that can make roadside work safer. If it cannot, tell the provider exactly where the vehicle is and whether it blocks a live lane.

Tell the provider what equipment you have

Mention whether the vehicle has a usable spare, wheel-lock key, jack kit or run-flat tires. Send the year, make and model and a photo of the damaged tire if safe to take one.

Towing may be better than a roadside repair

A damaged wheel, multiple flat tires, unsafe roadside position, missing spare or suspected suspension damage can turn a simple tire call into a tow. Clear symptoms help dispatch the right service the first time.
