What a tire change needs
A usable spare tire and a safe place to work. Many newer vehicles carry an inflator kit instead of a spare; if there is no usable spare, a tow may be needed instead.
Temporary spares are built for short distances at reduced speeds. Follow the limits printed on the spare and have the original tire repaired or replaced.
How S.O.S. handles it
The driver selects Flat Tire Help, shares a location and notes the vehicle. A SUPERHERO who accepts arrives with tools to remove the wheel and mount the spare.
Safety
Changing a tire next to moving traffic is dangerous. If the vehicle is on a narrow shoulder or a highway, move away from the travel lanes when possible and wait in a safe place. NHTSA publishes guidance on tire safety and maintenance.
