put air in tyres

Find the tyre-pressure placard (usually on the driver’s door jamb or fuel flap) and note the recommended cold pressure. Roll up to a servo, set the inflator to that number, remove the valve cap, and clamp the hose on straight—no hissing is good hissing.

Inflate until the machine beeps or shows you’ve hit the target, then repeat for all four corners and the spare (space-savers often need much higher pressure). Do it when the tyres are cold; if you’ve just driven, add a touch and recheck properly next morning. Don’t chase race-car numbers—overinflated tyres ride like a shopping trolley, underinflated ones chew fuel and tread. When you’re done, replace the caps and bask in the smug glow of properly set rubber.
