Spare tires can get you out of a tight spot if you get a flat, but they are only a temporary solution.
There are different types of spares, including full-size spares, compact spares (also known as “donuts”), and run-flat tires, and each has its own quirks. But all spares are designed for limited use.
So, how long can you drive on a spare tire before you start to have problems? Here’s what you need to know about driving on a spare.
Types of spare tires and their characteristics
The type of spare tire you have will determine how far and how fast you can drive on it. Here’s a rundown of the most common types:
Full-size spare tire
A full-size spare is the same size and has the same specifications as your car’s original tires. If it’s in good condition, you can drive on it for an extended period. If the spare is identical to the other tires, you can include it in your regular tire rotation.
One thing to watch for: The tread pattern on the spare may be different from the tread pattern on your other tires, which could affect traction.
Compact spare tire (donut spare)
A compact spare, also known as a “donut,” is a smaller, lighter tire that’s meant for temporary use only. The idea is to get you to a repair shop so you can get your regular tire fixed or replaced.
- Maximum recommended distance: 50-70 miles
- Maximum recommended speed: 50 mph
Check the sidewall of the tire for any other usage restrictions.
Run-flat tire
Run-flat tires are designed to maintain their pressure, allowing you to drive a limited distance even after a puncture.
Typically, you can drive up to 50-70 miles at speeds up to 50 mph on a run-flat tire.
Driving Limitations and Safety Precautions
It’s important to know that a spare tire isn’t meant to be a permanent fix. Here are some things to keep in mind.
Understanding Driving Limitations
- Compact spares are for temporary use only. Driving too far or too fast on a compact spare can be dangerous. Try to avoid rough roads while you’re using it.
- Full-size spares may still have limitations if they’re not the same as your other tires. Different tread patterns can impact how your car handles. You should replace it with a matching tire as soon as you can.
- Even run-flat tires will eventually need to be replaced. They’re designed to let you keep driving after a flat, but they’re not a long-term solution.
Safety Precautions
No matter what kind of spare you’re using, these safety tips are important:
- Check the tire pressure before you drive. Make sure your spare is inflated properly.
- Stick to the speed and distance limits for your spare tire type. Follow the manufacturer’s advice.
- Drive carefully and avoid quick turns or stops. Spare tires can change the way your car handles and brakes.
- Get your spare replaced with a regular tire as soon as possible.
Maintaining Your Spare Tire
Most people forget their spare tire until they need it. But regular maintenance can ensure your spare is ready when you are.
To keep your spare in good shape:
- Routinely check for wear and damage. Look for cuts, bulges, and uneven wear.
- Keep it properly inflated to the recommended tire pressure.
- Store it in a clean, dry place.
- If you have a full-size spare, factor it into your regular tire rotation.
Changing to a Spare Tire: A Quick Guide
Swapping out a flat tire for a spare can get you back on the road, but it’s important to do it safely. Here’s a quick rundown:
- Safety First: Park on level ground away from traffic. Turn on your hazard lights.
- Gather Tools: Find your spare tire, jack, and lug wrench.
- Loosen Lug Nuts: Before jacking, loosen the lug nuts on the flat tire.
- Jack Up the Car: Place the jack properly and lift the car until the flat tire is off the ground.
- Remove Flat Tire: Unscrew the lug nuts completely and remove the flat.
- Install Spare Tire: Put the spare on the wheel studs and hand-tighten the lug nuts.
- Lower the Car: Lower the vehicle with the jack.
- Tighten Lug Nuts: Fully tighten the lug nuts in a star pattern.
- Check Tire Pressure: Inflate the spare to the correct pressure.
- Get the Flat Fixed: Get the flat repaired or replaced ASAP and put back on!
In Closing
It’s important to remember that using a spare tire is only a temporary fix. You need to replace your spare with a standard tire as soon as you can.
Knowing the limitations of your spare tire — whether it’s a full-size spare, a temporary or “donut” spare, or a run-flat tire — is essential for your safety. And whatever kind of spare you have, remember to take extra precautions when you’re driving on it.
