View Here : Tyre Pressure In Cold Weather
November 13, 2010, 7:38:20 PM EST. In the fall, the colder weather will significantly lower your tire pressure. If your tire pressure has been set during the hot summer months, the first major cold wave will cause the air to contract inside your tire, lowering the pressure, thus setting off your TPMS.
Check your tire inflation level (PSI) in cold weather before driving your vehicle, when the car is cold (sitting for a minimum of 3 hours). Driving causes the PSI to increase, making the reading inaccurate if tested after driving. 4. Remove the valve-stem cap on 1 or all 4 tires (you will check all 4 tires).
Pressure drops more common in winter. That’s because air contracts when it’s cold, causing tire pressure to drop between one and two pounds for every 10-degree decrease in temperature. This means that your tires could be 5 to 10 psi lower than required on a 24-degree day than they are on a 74-degree day.
So now, the temperature drops over night overnight temperature hits the low 40s, your tire pressure will drop down by 5 psi, almost certainly turning on the tire pressure warning light . To remedy your low tire pressure light, a simply check or adjustment of the air in your tires is all that is required.
Checking tire pressure in cold weather is the same as in the heat, but is increasingly important, as inflation tends to drop with temperatures.
Tyre pressures in cold weather. Tyre pressure is usually measured in pounds per square inch, or PSI (even though we live in a country that uses the metric system). You might also see kilopascals (kPa) used. The air in the tyre expands (increases pressure) when it’s warmed and contracts as it cools down.
Cold Weather is Here, Check Your Tire Pressure. As we transition to cooler weather in much of the Northern Hemisphere, now is a good time to check your tire pressure. Tire pressures are set at ambient temperature, and a 10 degree drop in ambient temperature drops your tire pressure roughly 1 psi. So a tire that was set perfectly at 75 degrees….
Winter Tire Pressure. Temperature changes outside affect your tire pressure. If it gets up to 45 degrees by day and drops to 15 degrees at night, your tire pressure will vary 3 PSI, not counting normal air loss. This is why it's not unusual to have the low pressure indicator light go on first thing in the morning,...
Tire manufactures say the onset of winter weather is a good time to make sure your tires are properly inflated. Air pressure can affect steering, handling, gas mileage, and the life of the tires ...
