Many drivers assume they are legally required to carry a spare tyre. In the UK, this is not the case. However, there are important rules around the spare tyres and emergency kits that do come with your car.
Is a spare tyre a legal requirement in the UK
No. There is no UK law requiring you to carry a spare tyre, a space-saver spare, or a puncture repair kit. However, an MOT test requires that every tyre fitted to the vehicle meets the legal requirements. A spare tyre stored in the boot that is not fitted to the car is not tested during an MOT.
Space-saver spare tyres
Many cars come with a space-saver spare (a narrower, lighter emergency spare) rather than a full-size spare. Space-saver tyres have strict limitations printed on the tyre sidewall and in the handbook. Typically: maximum speed of 50 mph; maximum distance of around 50 miles; not suitable for motorway driving in some cases. Exceeding these limits is dangerous and may invalidate your insurance.
If you have run-flat tyres
Most cars fitted with run-flat tyres from the factory do not come with a spare tyre at all. If you get a puncture beyond the run-flat driving limits, you will need roadside assistance. Check whether your breakdown cover includes tyre replacement or whether you need to add it separately.
Tyre puncture repair kits
Many newer cars come with a foam-based puncture repair kit instead of any spare. These are effective for small tread punctures but cannot repair sidewall damage, large cuts or blowouts. If you have used a repair kit, the tyre must be inspected and usually replaced before your next long journey.
