How to Check Tyre Pressure Correctly

AH Mobile Tyre Fitting provides 24/7 tyre replacement throughout Leeds and Yorkshire. The guidance below helps you make a safer decision before professional assistance arrives.

Use the vehicle’s specified pressure

Find the pressure label inside the fuel flap, door opening or handbook. Front and rear figures may differ, and a heavily loaded vehicle can require a different setting.

Check when tyres are cold

Pressure rises as a tyre warms, so measure before a long drive where possible. Remove the valve cap, fit the gauge squarely and replace the cap afterwards.

Investigate repeated pressure loss

A tyre that regularly needs air may have a puncture, valve leak or rim-sealing problem. Do not treat frequent top-ups as a permanent solution.

Why pressure matters

Underinflation increases sidewall flex, heat, rolling resistance and shoulder wear. Overinflation can reduce the contact area and contribute to centre wear or a harsher response to impacts. Correct pressure supports predictable handling, braking, fuel use and tyre life.

How often to check

Check at least monthly, before long journeys, after a major temperature change and whenever the tyre-pressure warning appears. The dashboard system is a warning aid rather than a replacement for a gauge and visual inspection.

Use a reliable gauge

Remove the valve cap, place the gauge squarely on the valve and compare the reading with the cold-pressure specification. Add or release air in small steps and recheck. Replace the cap afterwards and remember that front and rear figures may differ.

Do not forget the spare

Where a vehicle carries a spare wheel, include it in routine checks. A spare that has slowly lost pressure may be unusable when a puncture occurs. Space-saver wheels also have specific inflation, speed and distance limits.

Warning signs of incorrect pressure

Heavy steering, pulling, extra road noise, a changed ride, uneven wear or a warning light can all justify a check. Stop driving if pressure is dropping rapidly or the tyre is visibly damaged.

When pressure loss becomes an emergency

A visibly flat tyre, rapid deflation, bulge or exposed cord should not be driven to a garage. Move to a safe place and call for assistance. AH Mobile Tyres can assess or replace the tyre at an accessible location across Leeds and West Yorkshire.
