Incorrect tyre pressure costs UK drivers millions in wasted fuel every year — and it can be deadly. Here's why getting pressure right matters so much.
Under-inflated tyres increase rolling resistance, meaning your engine works harder and burns more fuel — typically adding 3-5% to your fuel costs. More critically, under-inflation causes excessive heat build-up in the tyre, which is the leading cause of motorway blowouts. Over-inflation reduces the tyre's contact patch with the road, increasing braking distances and reducing lateral grip. Check pressure monthly and always when the tyres are cold.
KEY TAKEAWAYS
- Under-inflation increases fuel consumption by up to 5%
- Over-inflation reduces grip and increases stopping distances
- Cold tyre pressure is the accurate baseline — not after a long drive
- Correct pressure found in the driver's door jamb sticker
- Consider a quality digital tyre gauge — they're far more accurate than forecourt gauges
