How often should I check my tyre pressure?
Experts say that you must check your tyre pressure at least once a month and before going on a long trip. Also, make it a habit to check your tyres every time you fill up with fuel. Ideally, tyre pressure should be measured when tyres are cold—that is, when you have driven less than a mile. Otherwise, your tyres may have heated up, increasing the air pressure inside them by several pounds. This is normal. Never “bleed” or reduce the air pressure in a hot tyre.
