Flat tyres are a common inconvenience that almost every driver faces at some point. Whether you're on your way to work or in the middle of a road trip, a sudden puncture can quickly derail your plans. That’s when a spare tyre comes into play. But how long can you actually drive on a spare tyre? Is it safe to keep going for hours or even days? The answer depends on the type of spare tyre you have and several other factors.
Not all spare tyres are created equal. There are two main types that come with most vehicles: full-size spare tyres and compact temporary spare tyres, also known as space-savers or donuts.
A full-size spare tyre is just what it sounds like—a regular tyre that matches the size and specifications of the other tyres on your vehicle. These are commonly found in larger vehicles like SUVs, pickup trucks, and some full-size sedans.
Extended Driving Distance: You can drive a much greater distance on a full-size spare compared to a compact one.
Normal Speed Driving: Full-size spares can typically handle normal driving speeds.
Better Handling: Because they’re the same size and often the same type as your other tyres, handling remains relatively stable.
Make sure your full-size spare is properly inflated.
Periodically check its condition, especially if it’s been stored for a long time.
Even though it can go the distance, treat it as temporary unless it’s rotated in with your regular tyres.
Space-saver tyres are smaller and lighter than your standard tyres. They’re designed for one job: to get you to the nearest service center. These are most commonly found in compact cars, sedans, and hatchbacks.
Limited Distance: These tyres are generally rated for up to 70 miles (113 kilometers) of driving.
Speed Restrictions: You should not exceed 50 mph (80 km/h) when using a donut spare.
Reduced Traction and Performance: Donut spares are made of thinner rubber, have less tread, and are not designed for high-speed or long-term use.
As soon as possible. Their purpose is emergency transportation only.
You should drive directly to a tyre shop or service center after installing one.
Full-Size Spare Tyre
If your vehicle comes with a full-size spare tyre, you’re in a much better position compared to having a compact spare. Full-size spares are essentially the same as your regular tyres in terms of size, tread, and performance. This means you can generally drive on them just like you would on any other tyre, without having to drastically change your driving habits.
However, there are a few important things to keep in mind. First, the spare tyre may not have the same wear and tear as the other tyres on your vehicle. For example, if your regular tyres are halfway worn, but your spare is brand new, this difference in tread depth can affect your vehicle’s balance and handling. Additionally, even if the size matches, the brand or tread pattern on the spare might be different from the tyres currently on your car. This difference can slightly impact traction and performance, especially in wet or slippery conditions.
While a full-size spare is designed to provide better performance and can be driven for longer distances and at normal speeds, it’s still considered a temporary solution. As soon as possible, you should visit a professional tyre shop to repair or replace the damaged tyre and reinstall a properly matched set on your vehicle. This ensures consistent handling, safety, and wear across all four tyres.
Compact Temporary Spare Tyre (Donut)
For vehicles equipped with a compact temporary spare tyre—often called a “donut”—the rules are much stricter, and it’s crucial to follow them carefully to stay safe.
The key limits to remember are:
Maximum driving distance: about 70 miles (approximately 113 kilometers)
Maximum speed: 50 miles per hour (around 80 kilometers per hour)
These limits exist because compact spares are designed to be lightweight and space-saving, rather than durable for long-term use. Their construction is less robust compared to full-size tyres, meaning they can wear out or fail more quickly if used improperly. The tread design on these spares is also less effective, resulting in reduced grip and poorer traction, especially on wet or slippery surfaces.
Ignoring these limits by driving too far or too fast on a donut tyre increases the risk of serious problems. These include tyre blowouts, loss of vehicle control, and uneven braking performance due to the difference in tyre size and traction. Such issues can lead to accidents or damage to your vehicle.
Full-size spare tyres can be driven for longer distances and at normal speeds but should still be treated as a temporary solution until your regular tyre is repaired or replaced.
Compact temporary spares are intended only for short trips to get you safely to a repair shop. They have strict limits on speed and distance, and using them beyond these can be dangerous.
Following these guidelines helps ensure your safety and prevents further damage to your vehicle. Always prioritize replacing or repairing your regular tyre as soon as possible after using a spare.
While tyre type is the main factor, several other elements can influence how far and how safely you can drive on a spare.
As discussed, full-size spares offer better performance and longevity.
Donut spares have strict limits and must be replaced quickly.
Driving on bumpy or poorly maintained roads adds wear and tear.
Avoid off-road use entirely when using a compact spare.
High speeds and sudden braking put extra stress on the tyre.
Always drive cautiously and defensively while on a spare.
An underinflated spare can fail prematurely.
Always check the pressure of your spare before use—whether it's full-size or donut.
Carrying heavy passengers or cargo while driving on a spare increases risk.
Try to reduce vehicle load until your normal tyre is replaced.
Tyres degrade over time—even if unused.
Most manufacturers recommend replacing any spare tyre that is over 6 to 10 years old, regardless of wear.
To ensure your safety and get the most out of your spare tyre, follow these essential tips:
Check the tyre pressure.
Examine the spare for any visible damage or dry rot.
Ensure the lug nuts are tightened securely.
Avoid hard braking and sudden turns.
Stay in the right lane and drive at moderate speeds.
Avoid highways if possible—use local roads to reach the service center.
Keep your spare clean and dry.
Rotate full-size spares with your regular tyres to even out wear.
Periodically inspect the spare, especially before long trips.
A spare tyre is a vital safety feature that helps you avoid being stranded, but it’s only meant for short-term use. Whether it's a full-size or compact space-saver spare, always follow the manufacturer’s guidelines and replace or repair your main tyre as soon as possible. Regular maintenance and knowing your spare’s limits can prevent small issues from becoming major hazards.
