When you experience a flat tire, having a spare tire can be a real lifesaver. But how far can you drive on a spare tire before it needs replacing? In this article, we’ll delve into the different types of spare tires and wheels for sale, their driving limitations, and essential safety precautions to keep you informed and safe on the road.
Types of Spare Tires
Spare tires come in various types, each designed for specific purposes and limitations. Understanding the differences can help you make the best decision when a tire emergency arises.
Full-Size Spare Tire
A full-size spare tire is similar to your vehicle’s regular tire1. It provides the same traction, speed capability, and performance. However, it takes up more space in your vehicle.
Compact Spare Tire (Donut Spare)
Compact spares, often referred to as donut spares, are smaller and lighter than full-size spares. They are designed to save space and weight but have significant limitations in terms of speed, distance, and durability.
Run-Flat Tire
Run-flat tires allow you to drive for a limited distance at reduced speeds, even after a puncture. These are usually part of the vehicle’s original equipment and provide added convenience and safety.
Driving Limitations on Spare Tires
Driving on a spare tire is not meant to be a long-term solution. Each type of spare tire has specific limitations.
A full-size spare tire can generally be driven on as long as it is in good condition and matches your vehicle’s tire size and type. Compact spare tires, also known as donut spares, are designed for short-term use only.2 Most manufacturers recommend not exceeding 50 miles and driving no faster than 50 mph due to their reduced traction, which can affect handling and braking. Meanwhile, run-flat tires typically allow you to drive up to 70 miles at speeds up to 50 mph, giving you enough time to reach a tire shop for repair or replacement.
Understanding these limitations helps ensure your safety and the proper function of your vehicle until you can replace the spare with a standard tire. Always be mindful of the specific guidelines for the type of spare tire you have to avoid potential issues on the road. You should also understand the ways tires can affect a car’s performance.
Safety Precautions When Using a Spare Tire
Using a spare tire comes with its own set of safety precautions to ensure you and your vehicle remain safe. Here are some of the things that you need to remember when using a spare tire:
- Check Tire Pressure: Before driving with a spare tire, always check the tire pressure. Underinflated or overinflated tires can be hazardous.
- Limit Speed and Distance: Follow the manufacturer’s guidelines for maximum speed and distance. Driving too fast or too far on a spare can lead to tire failure.
- Avoid Rough Roads: Spare tires, especially compact spares, are not designed for rough or uneven roads. Stick to smooth, paved surfaces whenever possible.
- Drive Cautiously: Spare tires, particularly compact ones, can alter your vehicle’s handling. Drive cautiously and avoid sudden maneuvers.
- Replace Promptly: Replace the spare tire with a full-size tire as soon as possible. Prolonged use of a spare can cause wear and tear on your vehicle.
Maintenance Tips for Spare Tires
Proper maintenance of your spare tire can ensure it’s ready for use when you need it.
- Regular Inspections: Check the condition of your spare tire regularly. Look for signs of wear, damage, or aging.
- Keep It Inflated: Maintain the recommended tire pressure for your spare. Underinflated tires can be dangerous when you need to use them.
- Store Properly: Ensure your spare tire is stored correctly. For full-size spares, avoid placing heavy objects on top of them.
- Rotate Spares: If you have a full-size spare, include it in your regular tire rotation schedule. It ensures even wear and extends the life of all your tires.
How to Change to a Spare Tire
Knowing how to change a flat tire is a crucial skill for any driver. Here’s a step-by-step guide:
Step 1. Find a Safe Location: Pull over to a safe, flat area away from traffic.
Step 2. Gather Tools: You’ll need a jack, lug wrench, and a spare tire. Choose a reliable one from the different types of tires available.
Step 3. Loosen Lug Nuts: Before jacking up the vehicle, loosen the lug nuts slightly.
Step 4. Jack Up the Vehicle: Use the jack to lift the vehicle until the flat tire is off the ground.
Step 5. Remove the Flat Tire: Take off the lug nuts and remove the flat tire.
Step 6. Install the Spare: Place the spare tire on the wheel studs and hand-tighten the lug nuts.
Step 7. Lower the Vehicle: Lower the vehicle and tighten the lug nuts securely in a star pattern.
Step 8. Check Tire Pressure: Make sure that the spare tire is inflated correctly before driving.
