Spare Wheel Essentials: What Every Learner Driver Should Know

Spare Wheel

Understanding the basics of spare wheels is crucial for learner drivers. It’s not just about having one in the boot; it’s about knowing its importance, how it works, and the differences between the types of spare wheels available.

The Importance of Having a Spare Wheel

Safety and preparedness are paramount when driving. A spare wheel is a fundamental safety net, ensuring you’re never left stranded due to a flat tyre.

The confidence it brings, knowing that you can address such a common issue, is invaluable, particularly for learner drivers who are still building their road confidence.

Understanding the Role of a Spare Wheel in Emergency Situations

In an emergency, a spare wheel is your best friend. Whether it’s a puncture or a blowout, having a spare wheel means you can get back on the road quickly, minimising disruption to your journey and ensuring you’re not stuck in potentially unsafe locations.

How a Spare Wheel Can Save Time and Stress

Imagine you’re running late for an important appointment or it’s late at night; a flat tyre can significantly add to your stress levels.

However, if you have a spare wheel and the knowledge to change it, you can significantly reduce the time you’re off the road.

This autonomy removes the need to wait for roadside assistance and gets you moving faster, reducing stress.

The Differences Between Full-Size and Space-Saver Spare Wheels

Learner drivers should be aware of the two main types of spare wheels: full-size and space-saver.

  • Full-size spare wheels are identical to the other wheels on your vehicle. They allow you to continue your journey without any immediate need to visit a garage, although you should still get the damaged tyre checked as soon as possible.

  • Space-saver spare wheels, also known as donut spares, are smaller and not intended for long-term use. They’re designed to save space and weight in the vehicle, allowing you to get to a garage for a permanent fix. It’s crucial to adhere to the speed and distance limitations of space-saver spares to ensure safety.

Types of Spare Wheels

The type of spare wheel you carry can make a big difference in how you handle a flat tyre situation. Each type has its specific uses, benefits, and limitations.

Full-Size Spare Wheels: Pros and Cons


  • Durability: Full-size spare wheels are as durable as the regular tyres on your car, allowing you to continue your journey without immediate worry.
  • No Speed Limitation: Unlike space-savers, you can drive on a full-size spare at normal speeds.
  • Long-Term Use: They can be used for longer distances, essentially until you can get the original tyre repaired or replaced.

  • Space and Weight: Full-size spares take up more boot space and add weight to your vehicle, which can affect fuel efficiency.
  • Cost: They are more expensive than space-savers due to their size and the fact they are fully functional tyres.

Space-Saver Spare Wheels: When and How to Use Them

Space-saver spare wheels, or “donuts,” are designed for temporary use to get you to a garage for a repair.

When to Use Them:

  • Emergency Situations: Ideal for getting you out of immediate trouble and to the nearest repair shop.
  • Limited Space: Perfect for vehicles where boot space is at a premium.

How to Use Them:

  • Speed Limitations: Usually, you should not exceed 50 mph (80 km/h) on a space-saver.
  • Distance Limitations: It’s recommended to not use them for more than 50-70 miles (approximately 80-112 kilometres).

Run-Flat Tyres: An Alternative to Traditional Spare Wheels

Run-flat tyres are a modern alternative, designed to keep you moving for a certain distance, even after they lose air pressure.


  • Safety: They reduce the risk of accidents due to blowouts.
  • Convenience: Eliminates the need for immediate tyre changes at the roadside.
  • Space-Saving: Frees up space in the boot since there’s no need for a spare.


  • Cost: They are more expensive than standard tyres.
  • Ride Comfort: Some drivers find the ride harsher due to the stiffer sidewalls.

Checking and Maintaining Your Spare Wheel

Regular checks and maintenance ensure your spare wheel is ready when you need it.

How to Check Your Spare Wheel’s Condition

  • Visual Inspection: Look for any signs of wear, tear, or damage. Check the tread depth to ensure it’s within legal limits.
  • Tyre Pressure: Ensure the tyre pressure is at the recommended level, as it can lose air even when not in use.

Regular Maintenance Tips for Spare Wheels

  • Routine Checks: Incorporate spare wheel checks into your regular vehicle maintenance schedule.
  • Rotation: If you have a full-size spare, include it in your tyre rotation plan to ensure even wear.
  • Storage: Keep it properly secured in your vehicle to prevent damage while driving.

Understanding Tyre Pressure for Spare Wheels

  • Correct Pressure: It’s crucial for both safety and tyre longevity to maintain the correct pressure, which may differ from your regular tyres.
  • Regular Checks: Tyre pressure should be checked monthly and before long trips, as spare wheels can lose pressure over time even if not used.

How to Change a Tyre

Changing a tyre might seem daunting at first, but with the right tools and knowledge, it can be a straightforward process.

Essential Tools for Changing a Tyre

To change a tyre, you need a few key tools: a jack, a lug wrench, and ideally, wheel wedges. Some vehicles also come with a tyre pressure gauge and a tyre inflator, which can be extremely helpful. Ensure these tools are always in your vehicle and that you know where they are and how to use them.

Step-by-Step Guide to Changing a Tyre Safely

  1. Safety First: Before attempting to change a tyre, make sure you’re in a safe location, away from oncoming traffic. Turn on your hazard lights to alert other drivers.
  2. Prepare Your Vehicle: Apply the parking brake and place wheel wedges under the tyres opposite to the one you’re changing to prevent rolling.
  3. Loosen the Lug Nuts: Using the lug wrench, loosen (but do not fully remove) the lug nuts on the wheel.
  4. Lift the Vehicle: Position the jack under the vehicle frame near the tyre you’re changing and raise the vehicle until the tyre is off the ground.
  5. Remove the Tyre: Take off the lug nuts and remove the tyre.
  6. Mount the Spare Tyre: Place the spare tyre on the wheel base and replace the lug nuts, tightening them by hand initially.
  7. Lower the Vehicle and Tighten the Lug Nuts: Lower the vehicle fully and then tighten the lug nuts with the wrench, ensuring they’re secure.
  8. Check and Adjust Tyre Pressure: If possible, check the tyre pressure and adjust if necessary.
