Space-saver spare tyres are designed for emergency use only, with strict speed and distance limits. We cover the rules and why you should replace it as soon as possible.
Space-saver spare tyres — the narrow, temporary spares found under the boot floor of many modern cars — are designed for one specific purpose: getting you safely to the nearest point of assistance after a tyre failure. They are not substitutes for a full-size tyre.
1Speed and Distance Limitations
Space-saver spare tyres have strict manufacturer-specified usage limits, typically a maximum of 50 mph and no more than 50 miles of total travel. These limits exist because space-saver tyres use a thinner construction that is not rated for sustained high-speed or long-distance use.
2How a Space-Saver Affects Handling
A space-saver is narrower and lighter than a standard tyre, which affects braking distance, cornering stability and the behaviour of ABS, traction control and stability control systems. Drive smoothly, avoid sharp manoeuvres, leave extra braking distance and avoid motorways if possible.
3If Your Car Has No Spare at All
An increasing number of vehicles are delivered without any spare tyre, relying solely on a tyre inflation and sealant kit. If you drive such a vehicle, it is worth saving the contact number of a 24/7 mobile tyre service — a sealant kit cannot help with a sidewall failure or a badly damaged tyre.
4Act Promptly After Fitting a Spare
As soon as a space-saver spare is fitted, treat replacing it as a priority rather than a convenience. Driving on a space-saver for days or weeks is unsafe and may void your vehicle's warranty or insurance in the event of an incident attributable to the non-standard tyre.
