Your tyres are the only part of the car that touches the road. Four patches, each about the size of your palm, carry the entire weight, every turn and every stop. Keeping them at the right pressure is the highest-value, lowest-effort thing you can do for safety and running cost alike.
Why pressure matters more than you think
- Under-inflation flexes the sidewall, builds heat and can cause a blowout at speed
- It wears the tyre edges faster, shortening its life
- It increases rolling resistance — you literally burn more fuel
- It makes the car feel vague and increases your stopping distance
Check pressures cold, once a month
Measure pressures when the tyres are cold, against the figure on the sticker in your door shut or inside the fuel flap — not the maximum printed on the tyre sidewall. Pressures drop naturally over time, and faster as the weather turns cold, so a monthly check and a glance before any long trip is the habit to build.
If you get a puncture
A slow leak often lets you reach a garage safely — drive gently and keep an eye on the pressure. A sudden blowout is different: hold the wheel firmly, ease off the accelerator, and let the car slow before braking gently. Never brake hard or yank the wheel.
