10-86 Vehicle Care After installing the spare tire on the vehicle, you should stop as soon as possible and make sure the spare is correctly inflated. The spare tire is made to perform well at speeds up to 112 km/h (70 mph) at the recommended inflation pressure, so you can finish your trip. Have the damaged or flat road tire repaired or replaced as soon as you can and installed back onto the vehicle. This way, a spare tire will be available in case you need it again. Do not mix tires and wheels of different sizes, because they will not fit. Keep the spare tire and its wheel together. To continue changing the flat tire, return to Step 4 of "Storing a Flat or Spare Tire and Tools" under Tire Changing on page 10‑75.
