Space-saver, full-size, or no spare at all
A full-size spare can be driven normally if the tread and pressure are legal, though it should match the other tyres on that axle as soon as you can. A space-saver is a temporary: lower speed, shorter distance, and the pressure printed on that spare — often much higher than the car’s normal tyres. A can of sealant is not a spare. Many cars around Heathrow have neither, which is why mobile tyre fitting exists.
What we do with the wheel in the boot
- Fit the spare if you are stranded and the spare is safe.
- Check its pressure and age. A ten-year-old spare with cracks should not go on the car.
- Take the punctured tyre away for a proper puncture repair or replacement, then refit it so you are not left on the space-saver.
- Show you where the locking nut key and jack live, if the car still has them.
Do not keep a space-saver on the drive to work for a fortnight. They are not built for it, and a front space-saver on a drive axle upsets the differential if the rolling circumference is very different.
Book spare tyre help
Call +44 7771 363978 and say whether the spare is already on the car or still in the boot. If there is no spare, we treat it as a flat tyre call-out and bring a repair or a new tyre.
Questions drivers ask us
Can I drive to Staines on a space-saver?
Only within the speed and distance printed on the spare, and only if it is inflated. If you are unsure, stay put and call.
The spare is flat too. Can you help?
Yes. We can inflate a sound spare or bring a new tyre so you are not waiting on two flats.
Do you sell spare wheels?
We fit and repair tyres and can advise on a spare. Call with the car registration and we will say what is realistic.
