Overnight the temperature drops to \u221210 \u00b0C, and the local atmospheric pressure is 14.7 psi (sea level). First convert the temperatures to kelvin: \\(T_1 = 293.15\\) K and \\(T_2 = 263.15\\) K.<\/p>\n<p>\\[ P_1^{abs} = 32 + 14.7 = 46.7 \\ \\text{psi} \\]<\/p>\n<p>\\[ P_2^{abs} = 46.7 \\times \\frac{263.15}{293.15} \\approx 41.92 \\ \\text{psi} \\]<\/p>\n<p>\\[ P_2 = 41.92 - 14.7 \\approx 27.2 \\ \\text{psi} \\]<\/p>\n<p><strong>Result:<\/strong> the gauge pressure falls to about <strong>27.2 psi<\/strong> (187.7 kPa) \u2014 a drop of 4.8 psi overnight. These are exactly the calculator's default values, so you can reproduce the result with one click.<\/p>\n<p>\n\r\n<\/section>\n<h2>How to use the calculator<\/h2>\n<ol>\n<li>Enter your <strong>Current tire pressure (P\u2081)<\/strong> \u2014 the reading from your tire gauge \u2014 and choose its unit (psi, bar, kPa or kg\/cm\u00b2).<\/li>\n<li>Enter the <strong>Current air temperature (T\u2081)<\/strong>, i.e. the temperature at which that pressure was measured, and pick \u00b0C, \u00b0F or K.<\/li>\n<li>Enter the <strong>Expected air temperature (T\u2082)<\/strong> the tires will be exposed to, such as an overnight frost or a hot summer afternoon.<\/li>\n<li>Enter the <strong>Atmospheric pressure (P atm)<\/strong> for your location. The default 14.7 psi (101.3 kPa) is the standard sea-level value; use a lower figure at high altitude. You can enter it in psi, inHg, kPa, bar or mmHg.<\/li>\n<li>Read the results: the approximate gauge pressure <strong>P\u2082<\/strong> at the new temperature (shown in psi, bar, kPa and kg\/cm\u00b2) and the pressure change <strong>\u0394P<\/strong>.<\/li>\n<\/ol>\n<h2>Why tire pressure changes with temperature<\/h2>\n<p>The air inside a tire behaves roughly like an ideal gas in a container of fixed volume. When the temperature falls, the air molecules move more slowly and strike the tire walls less forcefully, so the pressure drops; when the temperature rises, the pressure rises. Gay-Lussac's law makes this relationship exact for an ideal gas: pressure is directly proportional to absolute temperature, measured in kelvin. That is why the calculator quietly converts your \u00b0C or \u00b0F input to kelvin behind the scenes.<\/p>\n<p>A detail that many rule-of-thumb charts get wrong is the distinction between gauge and absolute pressure. Your gauge reads zero when the tire is at atmospheric pressure, but the air inside is still at ~14.7 psi absolute. The temperature acts on the absolute pressure, so the correct calculation must add atmospheric pressure first and subtract it again at the end. Doing this properly is what this calculator does \u2014 and it is also why the answer depends slightly on your altitude.<\/p>\n<p>In practice, a typical passenger-car tire loses or gains roughly 1 psi for every 10 \u00b0F (about 5\u20136 \u00b0C) of temperature change. A car parked in a 20 \u00b0C garage and then left overnight at \u221210 \u00b0C can drop from 32 psi to about 27 psi \u2014 enough to trigger a TPMS low-pressure warning and to noticeably worsen handling, braking and fuel economy. The effect also works in reverse: pressure measured after a long drive, when the tires are warm, reads several psi higher than the \"cold\" pressure the manufacturer specifies.<\/p>\n<h2>Assumptions and practical tips<\/h2>\n<ul>\n<li><strong>Constant volume.<\/strong> The tire is assumed rigid. Real tires expand slightly under pressure, so measured changes are typically a few percent smaller than calculated.<\/li>\n<li><strong>Dry air.<\/strong> Humid shop air can condense at low temperatures, slightly reducing the pressure drop predicted here. Nitrogen-filled tires follow the same law.<\/li>\n<li><strong>Air temperature, not tire temperature.<\/strong> Enter the temperature the tire is soaking in. After driving, the tire carcass is warmer than the ambient air \u2014 if you measure pressure right after a trip, use the approximate warm-tire temperature as T\u2081.<\/li>\n<li><strong>Always check pressures cold.<\/strong> Manufacturers specify cold inflation pressure (usually measured at ambient temperature after the car has been parked for a few hours). Adjust pressures in the morning before driving whenever possible.<\/li>\n<li><strong>Adjust for the season, not the moment.<\/strong> In winter, inflate to the placard pressure at the coldest expected temperature rather than topping up to the placard value in a warm garage, or you will overinflate once the tire cools down outside.<\/li>\n<li><strong>Altitude matters a little.<\/strong> At 1,500 m (5,000 ft) above sea level, atmospheric pressure is around 12.2 psi instead of 14.7 psi. The calculator handles this \u2014 just enter your local value.<\/li>\n<\/ul>\n<h2>Quick reference: 32 psi tire at sea level<\/h2>\n<p>The table below shows the expected pressure for a tire inflated to 32 psi (gauge) at 20 \u00b0C and 14.7 psi atmospheric pressure.
