Remove the temporary spare tire and re-install the conventional tire as soon as possible because the spare tire is designed only for temporary use. Check the inflation pressure of the temporary spare tire periodically to keep the tire ready for use. The correct pressure is 60 psi (420 kPa, 4.2 kgf/cm2). When using the temporary spare tire, note the following. Do not exceed 50 mph (80 km/h). Do not put a tire chain on the temporary spare tire.
