Almost every car carries some tyre equipment, and a surprising number carry a set that will not actually get the job done. The jack is under the boot floor, the brace is somewhere, the spare has not been checked in five years and the locking wheel nut key is in a house move box. Verifying beats assuming, and it takes ten minutes once.
The genuine essentials
- High-visibility vest for every occupant, stored in the cabin, not the boot. A boot that faces traffic is not somewhere to be rummaging.
- A torch, ideally a headtorch so your hands are free, with working batteries.
- A tyre pressure gauge. Small, cheap, and the only way to check pressures properly away from a forecourt.
- A phone power bank and cable. A phone hunting for signal drains fast.
- The locking wheel nut key, in a known place.
That list is short because it is the list that actually gets used. Everything beyond it is a bonus rather than a necessity, and a boot full of equipment you have never opened is not preparation.
Check what the car already has
Lift the boot floor and establish which of three situations you are in: a full-size spare, a space saver, or a sealant kit and compressor. Each changes what you can do at the roadside, and many drivers do not know which they have until they need it. See spare wheel vs repair kit.
If there is a spare, check its pressure, because a spare loses air over years exactly like any other tyre, and check its condition for cracking. That is covered in spare wheel maintenance.
The locking wheel nut key
This deserves its own heading because it is the single most common reason a driver with a perfectly good spare still cannot change a wheel. Keys go missing between owners, get left at garages, and wear out so they no longer grip.
Find yours and actually try it on a nut rather than assuming it fits. If it is missing or damaged, that is worth resolving before you need it; we carry master sets and extraction tools, as covered in locking wheel nut removal.
Things people carry that do not help much
A warning triangle is required in some countries but the Highway Code advises against using one on a motorway, because placing it means walking in a live traffic environment. Guidance on breakdowns and obstructions is in the Highway Code.
A large aerosol sealant is also less useful than it looks: it does nothing for sidewall damage, can complicate a proper repair, and has an expiry date most people never check. Our view is in tyre sealant: good or bad.
The ten-minute audit
Once a year, ideally before winter: open the boot, find the spare and check its pressure, find the jack and brace, find the locking key and try it, check the torch batteries, and put a vest for each seat in the cabin.
Do the same for anyone else who drives the car. A spouse or a teenager who has never seen the boot floor lifted is in a considerably worse position at the roadside than you are, and a two-minute walkthrough fixes that.
If any of it is missing or the spare is flat, sort it out then rather than at the roadside. We can check the spare and the locking nut situation while we are with you for anything else. Book a check.
