Weekly Cold Tyre Pressure Checklist Uk Highway Code
A practical UK weekly habit is simple: check all four tyres—and the spare if your car still carries one—when they are cold, using the door-card PSI or BAR targets. Ten calm minutes on the driveway beats a rushed forecourt stop after the tyres have warmed up.
The Highway Code Annex 6 asks drivers to check tyre pressures weekly before the journey when tyres are cold. Under- or over-inflation affects braking and steering, so the checklist is maintenance, not optional trivia.
Ten-minute cold-tyre checklist
- Note the placard values for normal and, if listed, laden pressures—match the unit (PSI or BAR) on your gauge.
- Work cold: before a long drive, or after the car has stood for several hours.
- Attach a digital pump or quality gauge to each valve in turn.
- Set the target and inflate; auto-stop tools help you avoid guessing while you check the next corner.
- Refit valve caps, glance for obvious damage, and jot laden versus normal if you are packing for a trip.
The RAC advice on checking tyre pressure stresses cold readings, the door-frame sticker, and a reliable gauge. The Motor Ombudsman likewise points to the handbook, door frame or filler flap for recommended pressures.
Normal versus laden pressures
| Situation | Which placard column | When to switch |
|---|---|---|
| Daily commuting, light boot | Normal / unladen | Default weekly target |
| Holiday luggage, extra passengers | Laden / full load | Night before departure; revert after the trip |
| Sidewall max printed on tyre | Do not use as a target | Safety limit only—not your weekly set-point |
For a step-by-step laden switch before motorway holidays, see laden tyre pressure before UK holiday luggage. If you prefer home checks to station queues, compare options in petrol station air versus a portable cordless pump.
Who needs more than a consumer pump
Small fleets doing frequent commercial tyre work still belong on workshop compressors. A portable auto-stop unit is for driveway and roadside top-ups. When that fits your household, the Ipflinpor cordless tyre inflator is a compact UK-oriented choice—without claiming an MOT pass from pressure checks alone.
