If you’re asking yourself, “How long can I drive on a spare?”, Suntrup Automotive Group’s service center in St. Louis is here to answer that question and much more. To answer your question, you’ll want to replace your spare tire as soon as you can! If you’re riding around St. Charles with a full-size spare, then you have more time and mileage. However, a smaller space-saver will only give you 70 miles before needing a regular tire. But, you can learn more in detail on how long you can drive on a spare tire below.

 

 

How Long Can You Drive on a Spare Tire: Space-Saver Spare

First question: “How long can I drive on a spare space saver tire?” If you’re on a Fenton road and happen to only have a spare that is smaller than your normal tire, that is a space saver, otherwise known as a “donut”. Many vehicles have them, but here are a few things to consider with a space-saver spare:

  • Spares cannot be driven over 50 miles per hour
  • Spare tires shouldn’t be driven for more than 70 miles
  • You’ll have less traction than with a full-size spare

We recommend scheduling a service appointment quickly and visiting our parts center for a tire replacement.

How Long Can You Drive on a Spare Tire: Full-Size Spare

Full-size spare tires are typically found in new trucks and SUVs, but they’re not super common still. Full-size spares should still be replaced quickly as they last longer but typically cause poor traction and handling on St. Louis streets.

What Is a Run-Flat Tire?

Run-flat tires can maintain pressure even after a puncture. Run-flat spares offer a few disadvantages and advantages:

  • Remain inflated for about 50 miles following a puncture
  • Tougher than a space-saver tire or full-size spare
  • Often costs more than a standard tire

If you notice the tire pressure monitor get lower while driving with this spare, pull the vehicle over safely, and inspect the tire.
