spare. It should be set to the specified pressure.
Specified Pressure: 60 psi (420 kPa, 4.2 kgf/cm
2)
When driving with the compact spare tire, keep the
vehicle speed under 50 mph (80 km/h). Replace with
a full-size tire as soon as possible.
The compact spare tire and wheel in your vehicle are
specifically for this model.
Do not use them with another vehicle.
Do not use another type of compact spare tire or
wheel with your vehicle.
Do not mount tire chains on a compact spare tire.
If a chain-mounted front tire goes flat, remove one of
the full-size rear tires and replace it with the compact
spare tire. Remove the flat front tire and replace it
with the full-size tire that was removed from the rear.
Mount the tire chains on the front tire.
Do not use a puncture-repairing agent on a flat tire,
