How long can you drive on a spare tire?
Myth: You can drive normally on a smaller-sized spare tire.
Fact: The spare tire enables you to drive to the nearest repair shop to have the flat tire inspected and either repaired or replaced. You should not drive over 50 mph and no more than 50 miles with a donut-type spare tire. Driving for long distances on a spare tire can potentially cause damage to other car parts, including the transmission.
