Running into a flat tyre is never convenient. Whether it happens on a quiet suburban street or the middle of a highway, having a spare tyre in your car can feel like a lifesaver. But not all spares are created equal, and driving on one requires knowledge, caution, and a bit of planning.
Understanding how to use your spare tyre properly ensures you stay safe, protect your car, and get back on the road without causing further damage.
Types of Spare Tyres
Spare tyres generally fall into three categories:
- Full-Size Spare – This is the same size and type as your regular tyres. It allows normal driving but may have its own limitations depending on wear or age.
- Temporary/Donut Spare – Smaller and lighter, designed for short-term use. These spares save space but usually have speed and distance restrictions.
- Run-Flat Tyres – These can keep your car moving even after a puncture, usually up to 80 km at reduced speeds.
Knowing which spare your car carries is the first step in using it safely. Check your vehicle manual to understand the limits of your spare.
When It’s Safe to Drive on a Spare Tyre
Spare tyres are meant to be temporary solutions. They get you to a repair shop, tyre centre, or safe location—not to continue normal driving indefinitely.
Guidelines include:
- Temporary spares: Usually recommended for 50–80 km and speeds under 80 km/h.
- Full-size spares: Can often be driven normally but should still be replaced or rotated as soon as possible if it’s a new tyre.
- Run-flats: Follow manufacturer limits; prolonged high-speed driving is not advised.
Ignoring these guidelines can cause handling problems, uneven wear, or even blowouts.
How Driving on a Spare Tyre Affects Handling
Even when properly inflated, spare tyres can change how your car handles:
- Smaller spares may reduce traction, braking performance, and cornering stability.
- Different tread or wear on a spare can cause uneven handling or vibrations.
- Run-flat tyres often feel stiffer or harsher over bumps.
Drive cautiously, avoid sharp turns, and maintain moderate speeds until your regular tyre is repaired or replaced.
Safety Tips While Using a Spare Tyre
- Check Inflation: Before heading off, ensure your spare tyre is properly inflated. Underinflated spares can be dangerous.
- Limit Speed: Stay below the recommended speed limit for your spare, usually noted on the tyre itself or in the car manual.
- Avoid Long Distances: Spare tyres are temporary. Plan your route to the nearest tyre shop or repair centre.
- Monitor Handling: If the car feels unstable or pulls to one side, reduce speed and drive cautiously.
- Avoid Heavy Loads: Carrying extra weight can stress a spare tyre, especially temporary ones.
When to Replace the Original Tyre
Once you’ve used the spare, it’s important to repair or replace the original tyre promptly. Driving long-term on a spare, particularly a donut or smaller temporary spare, increases risks of:
- Uneven tyre wear
- Suspension or drivetrain strain
- Reduced braking and traction
Tyre shops can repair minor punctures or advise if a replacement is necessary. Always follow professional guidance to ensure safety.
Maintaining Your Spare Tyre
A spare tyre is only useful if it’s ready when you need it. Maintenance tips include:
- Regularly check pressure: Monthly inspections are ideal.
- Inspect for damage: Look for cracks, dry rot, or wear.
- Rotate if full-size: Some manufacturers recommend rotating full-size spares with regular tyres.
- Keep the jack and tools ready: Ensure all equipment is in good condition.
Neglecting your spare can leave you stranded when you need it most.
Why Having a Spare Tyre Matters
Even with roadside assistance or modern run-flat tyres, having a spare provides:
- Immediate mobility: You can continue your journey instead of waiting for a tow.
- Safety: Avoid being stranded in unsafe locations.
- Peace of mind: Knowing you have a solution ready reduces stress during emergencies.
For older cars or vehicles without roadside coverage, a spare tyre is often the fastest, most reliable backup plan.
When to Call for Help Instead
Sometimes, even with a spare, it’s safer to call for professional assistance. Situations include:
- Multiple tyre failures
- Severe damage to the vehicle body or suspension
- Lack of confidence to change the tyre safely
- Dangerous locations like highways or unlit roads
Professional tow and car removal services can help safely transport the vehicle, saving time and ensuring safety while you arrange permanent repairs.
Driving with a spare tyre is a convenient, practical way to deal with unexpected flats. By understanding your spare’s type, following speed and distance limits, and maintaining both the spare and your vehicle, you can get back on the road safely. Treat it as a temporary solution, drive cautiously, and make the repair or replacement as soon as possible to protect your car, your tyres, and most importantly, your safety.
