I remember the first time I got a flat tire. I pulled over, put on the spare tire, and thought, “How far can I drive on this?” I didn’t want to get stuck again!
Spare tires are just for emergencies. They are not like regular tires and can’t be used forever. If you drive too far or too fast, you could damage your car or even get another flat!
In this guide, I’ll share how long you can drive on a spare tire, how fast you should go, and when to replace it. Let’s make sure you stay safe on the road! 🚗💨
How Long Can You Drive on a Spare Tire?
The first time I used a spare tire, I thought I could drive forever on it. But that’s not true! Spare tires are only for emergencies and should be replaced as soon as possible.
How long you can drive depends on the type of spare tire you have.
1. Temporary (Donut) Spare Tire
🔹 This is the small spare tire most cars have.
🔹 It is not as strong as a regular tire.
🔹 Max distance: 50 to 70 miles
🔹 Max speed: 50 mph
📌 Tip: A donut spare is only for short trips to a repair shop!
2. Full-Size Spare Tire
🔹 Looks like a regular tire, but may not match your other tires.
🔹 You can drive farther, but it’s still temporary.
🔹 Max distance: A few hundred miles (replace it ASAP).
🔹 Max speed: Follow your regular tire limits.
📌 Tip: Even if it’s a full-size tire, don’t use it long-term!
3. Run-Flat Tires
🔹 Some cars (like BMWs) have run-flat tires that work even with no air.
🔹 These let you drive to a repair shop without needing a spare.
🔹 Max distance: 50 miles
🔹 Max speed: 50 mph
📌 Tip: Run-flats must be replaced once they lose air!
🚗 No matter what kind of spare you have, replace it as soon as possible! Driving too long on a spare can damage your car.
Why You Shouldn’t Drive Too Long on a Spare Tire
The first time I used a donut spare, I thought I could drive like normal. But after a few miles, my car felt weird! That’s when I learned that spare tires aren’t made for long trips.
Here’s why you should replace your spare tire quickly:
1. Less Grip & Control
✔️ Spare tires don’t have the same traction as regular tires.
✔️ If the road is wet or icy, your car may slip more easily.
2. Uneven Tire Wear
✔️ A small donut tire can make your other tires wear out unevenly.
✔️ This can mess up your alignment and suspension.
3. Risk of a Blowout
✔️ Donut spares are not as strong as normal tires.
✔️ Driving too far or too fast can cause the spare to blow out!
4. Braking & Turning Problems
✔️ Spare tires don’t stop as well as regular tires.
✔️ Sharp turns can feel wobbly or unsteady.
📌 Tip: If you’re using a spare tire, drive slowly and only go to a repair shop to get a new tire!
How to Drive Safely on a Spare Tire
When I had to drive on a spare tire, I was nervous. I didn’t want to go too fast or hurt my car. But after learning some safe driving tips, I made it to the repair shop with no problems!
If you ever need to use a spare, here’s how to stay safe on the road:
1. Check the Tire Pressure
✔️ Before driving, check the air pressure in the spare.
✔️ Most donut spares need 60 PSI (check your car manual).
2. Avoid Highways
✔️ Highways are too fast for a spare tire!
✔️ Stick to local roads and take the shortest route to a repair shop.
3. Drive Slowly
✔️ Keep your speed under 50 mph (for donut spares).
✔️ Driving too fast can make the spare fail!
4. Be Careful When Turning & Braking
✔️ Spare tires don’t grip the road like normal tires.
✔️ Slow down when braking and be extra careful on sharp turns.
5. Replace It As Soon As Possible
✔️ A spare tire is not a real tire—it’s only temporary!
✔️ Go to a tire shop as soon as you can to get a full replacement.
📌 Tip: I always keep a working spare tire in my car, so I’m ready for emergencies!
