Jump Starting; Jump Starting - North America - GMC HUMMER EV 2022 Owner's Manual

Have the damaged or flat road tire repaired
or replaced back onto the vehicle, as soon as
possible, so the spare tire will be available
in case it is needed again.
Do not mix tires and wheels of different
sizes, because they will not fit. Keep the
spare tire and its wheel together.
If this vehicle has a spare tire that does not
match the original road tires and wheels in
size and type, do not include the spare in
the tire rotation.
