A flat tire? No problem, as long as you have a spare wheel. But do you know the correct air pressure for your spare? The correct pressure in the spare tire is crucial for your safety and the life of the tire. In this article, you’ll learn everything important about spare tire pressure, from its importance and checking it to practical tips for emergencies.
What Does “Spare Tire Pressure” Mean?
The term “spare tire pressure” refers to the air pressure inside your spare tire. This pressure is measured in Bar or PSI and is critical for your vehicle’s driving stability and braking performance in the event of a flat tire. Incorrect air pressure can have serious consequences, from increased tire wear to dangerous handling.
The Correct Pressure: Where to Find the Information
You can find the correct air pressure specification for your spare tire in your vehicle’s owner’s manual, on a sticker inside the driver’s side door frame, on the fuel filler flap, or in the glove compartment. The recommended air pressure can vary depending on your vehicle model and tire type. Do not ignore these specifications! “A correctly inflated spare tire is the foundation for safe driving in case of a breakdown,” emphasizes Dr. Karl Schmidt, tire specialist and author of the book “The Physics of the Tire.”
Why Is Correct Pressure So Important?
The correct pressure in the spare tire ensures optimal handling characteristics and safety. Pressure that is too low leads to overheating, increased rolling resistance, and faster tire wear. In the worst case, the tire can come off the rim. Pressure that is too high, on the other hand, reduces the contact area with the road, leading to worse grip and longer braking distances.
How to Check Your Spare Tire’s Pressure
Checking the air pressure is simple and should be done regularly, at least once a month. Use a reliable tire pressure gauge. Unscrew the valve cap and place the gauge onto the valve. Compare the reading with the recommended air pressure for your spare tire. Adjust the air pressure if necessary at a gas station or with a compressor.

Spare Tire Pressure: Tips for Emergencies
In the event of a flat tire, it’s important to stay calm and follow these steps: Find a safe place to pull over. Secure the area. Change the wheel according to the instructions in your owner’s manual. Drive carefully and slowly to the nearest workshop to have the damaged tire repaired or replaced. “Remember, the spare tire is only a temporary solution,” explains engineer Anna Müller, an expert in vehicle safety, in her guide “Safe Driving on the Road.”
