Flat Tyre: What to Do and Can You Drive on One? Here’s What You Need to Know

Flat tyres happen to the best of us, and knowing how to handle one can save you time and help keep you safe. This guide walks you through everything you need to know, from spotting a flat tyre and understanding what causes it to knowing whether you can drive on one and what to do next. And when you do need professional support, we’re here with tyre services, repair and replacement to help you get back on the road with confidence.

How do I know if I have a flat tyre?

Sometimes, you may notice signs of a flat tyre before it becomes completely flat. Being aware of these warning indicators can help you act quickly and avoid further damage. Here’s what to look for:

• Handling feels “off”: If your car pulls to one side or steering becomes less responsive, a flat or punctured tyre might be to blame.

• Unusual vibrations or noises: A flat tyre often causes noticeable shaking, especially at slower speeds. You might also hear a flapping or thudding sound.

• A deflated appearance: If the rim looks lower or the tyre seems visibly deflated, it’s time to pull over and check.

• Dashboard warning light: If your car has a Tyre Pressure Monitoring System (TPMS), the warning light will alert you to low air pressure.

Routinely inspecting your tyres is a simple habit that can help you catch problems before they escalate. A quick tyre check now and then can make all the difference!

What causes flat tyres?

Understanding why tyres go flat can help you stay safe and avoid being caught off guard on the road. Look out for these common issues:

• Punctures from sharp objects: Nails, screws, glass or debris can easily pierce your tyre, causing an air leak.

• Wear and tear: Over time, tyres lose their tread or develop cracks, making them more prone to damage.

• Improper tyre pressure: Driving on tyres that are overinflated or underinflated can lead to uneven wear or even a blowout.

• Road hazards: Potholes, curbs or large bumps at high speeds can damage your tyre’s internal structure.

• Temperature changes: Cold weather can cause tyre air to contract, while hot weather may expand it, leading to fluctuating pressure levels.

If you’re concerned about unexpected tyre damage, HiQ's Accidental Damage Warranty helps cover the cost of repairs or replacement due to common causes of flat tyres, offering reliable protection and added peace of mind.

Can you drive with a flat or punctured tyre, and how far?

Driving on a flat tyre isn’t just risky – it can cause serious damage to your car. Without proper air pressure, the tyre can’t support your vehicle’s weight, putting extra strain on the wheel, suspension and other components.

If you absolutely need to drive on a flat tyre to reach a safe spot, keep it to a few hundred yards and stick to very low speeds. Pushing further or faster could damage the tyre beyond repair and even lead to a dangerous loss of control.

The safest move? Stop as soon as it’s safe to do so and sort the issue before continuing your journey. It’s always better to be cautious when it comes to your safety and your car.

Step-by-step: What to do when you have a flat tyre

Dealing with a flat tyre can feel overwhelming, but don’t worry, follow these simple steps to stay safe and get back on the road quickly.

1. Find a safe place to stop

Pull over to a flat, stable area that’s away from traffic. If possible, choose a well-lit location where there’s enough room to work around your car. Turn on your hazard lights to improve visibility to other drivers.

2. Inspect the tyre

Carefully assess the damaged tyre for visible issues, such as punctures, tears or deflation. Don’t forget to check the other tyres for good measure. If you have a Tyre Pressure Monitoring System (TPMS), use it to confirm which tyre is affected.

3. Decide on the next step

If the damage is minor, you might be able to seal it using an emergency repair kit. However, if the tyre is badly damaged, fitting a spare tyre will be necessary: read on for a step-by-step guide.

4. Drive cautiously to a repair shop

Spare tyres and temporary repairs are not designed for long-term use. After installing a spare, maintain lower speeds and avoid sudden braking or sharp turns. Head to your nearest HiQ Centre for tyre repair.

Everything you need to know about spare tyres

How to fit a spare tyre

Fitting a spare tyre is straightforward if you follow these steps:

1. Park your car on flat, level ground and make sure the handbrake is engaged.

1. Grab your spare tyre, jack and tyre wrench from your car.

1. Before lifting the car, use the tyre wrench to loosen the lug nuts on the flat tyre (but don’t remove them just yet).

1. Position the jack at the correct lifting point (check your car’s manual if you’re unsure) and raise the car until the flat tyre is completely off the ground.

1. Fully unscrew the lug nuts and carefully remove the damaged tyre.

1. Line up the spare tyre with the wheel bolts and secure it with the lug nuts. Tighten them in a star pattern to ensure even pressure.

1. Lower the car gently with the jack until the spare tyre is firmly on the ground. Tighten the lug nuts one final time to make sure they’re secure.

H3: Pros and cons of spare tyres

Spare tyres are a lifesaver when you’re stuck with a flat, offering a quick and reliable way to get back on the road. They’re easy to use in emergencies and especially handy if you’re far from a repair shop.

That said, it’s important to drive with care when using a spare, particularly temporary “donut” spares. These are designed for short-term use only, typically limited to 50-70 miles and speeds of around 50 mph. Exceeding these limits can lead to further issues, so stick to the guidelines. Be extra cautious around corners and during sudden braking, as handling and traction may be reduced.

If you’re using a full-size spare, it’ll last longer, but it’s still a good idea to repair or replace the damaged tyre as soon as possible to keep your car running safely and smoothly.

Tyre repair vs replacement

When it comes to tyre damage, the choice between repair and replacement depends on the severity and location of the issue. Minor punctures in the central tread area can often be repaired by professionals using patches or plugs, offering a quick, budget-friendly and eco-conscious solution. However, damage near the sidewall, large punctures or anything that compromises the tyre’s structure means replacement is the safest option.

While repairs are more affordable and reduce waste, they’re not suitable for all damage and require regular checks to ensure safety. Although replacing a tyre is more expensive, it guarantees reliability and often comes with a warranty for added peace of mind.

Run-flat tyres are specially designed to support your vehicle even after a puncture, allowing you to drive for a limited distance to safety or a repair shop. Curious if they’re right for you? Check out our full guide to Run-Flat Tyres for in-depth details.

Tips to prevent flat tyres

While not all flats are avoidable, taking care of your tyres can reduce your chances of experiencing one.

• Check tyre pressure regularly: Keeping tyres inflated to the recommended PSI helps them perform better and last longer.

• Inspect for damage often: Look for signs of wear, bulges or embedded objects. Address any concerns immediately.

• Rotate your tyres: Regular tyre rotation ensures even tread wear, extending the life of your tyres.

• Avoid road hazards: Take care when driving over rough terrain and keep an eye out for debris.

Flat tyres can be stressful, but understanding what to watch for and how to respond can make the situation much easier to handle. By recognising early warning signs, knowing the risks of driving on a flat, and taking the right steps during a puncture, you can safeguard both yourself and your vehicle.
