Sustained motorway speed and the heat it builds are exactly what expose a weak tyre, so a five-minute check before you set off prevents most long-distance breakdowns. Look at tread, pressures and condition while you're still on the drive, where any problem is a quick fix rather than a hard-shoulder emergency. Here's the checklist worth running.
Why motorways test tyres
A long motorway run combines high speed, sustained load and heat, hour after hour. A tyre that's marginal, under-inflated, worn or carrying hidden damage, is far more likely to fail under those conditions than on short local trips, see blowout causes. That's why pre-journey checks matter most before exactly this kind of drive.
The pre-journey checklist
- Tread: the 20p test on all four tyres, including inner edges.
- Pressure: set cold to the right figure, see tyre pressure.
- Condition: look all round for cracks, bulges and embedded objects.
- Spare: check the spare or repair kit is ready.
Pressures for a loaded car
A long journey often means a full car. A loaded car needs the higher laden pressure on your door placard, or the tyres run effectively under-inflated, which builds heat exactly when they're working hardest. Setting the laden figure before a fully packed motorway trip is one of the most effective things you can do to prevent a blowout.
On the journey
Take a break roughly every two hours. It keeps you alert and lets the tyres cool, and it's a chance to glance at them at the services. If a tyre looks low or the car feels different, stop and check rather than pressing on. If anything does go wrong, follow motorway breakdown safety.
