Checking your tire pressure is easy when the weather is warm, but a bit more difficult when colder weather arrives. For every 10 degrees fahrenheit the temperature drops, your tires can lose about 1 pound per square inch of pressure. For every month that passes you lose 1 PSI.
It’s generally recommended to keep your tires within 5 PSI of the suggested pressure so it’s important to check your tires’ air regularly in cold weather, according to TireRack.com.
Correct tire pressure is incredibly important especially in winter. Incorrect tire pressure can result in poor mileage, uneven tire wear or even a tire blow-out. The closer your tires’ air pressure is to the suggested manufacturer’s guidelines, the better your car will handle on the road.
With correct tire pressure, your tires will last longer, ride more evenly and provide better traction and durability .
Usually all it takes is a couple bucks for a tire gauge, a few minutes to check the pressure of each tire and then a trip to the gas station to add air when needed. In cold weather, it’s a little more difficult and you should check tire pressure more often.
As the temperature drops so does the temperature of the air inside your tires. Colder air outside causes the air to contract in the tires. Start driving and the air inside the tires heats up again — until you stop when the air inside the tires cools down.
Tire pressure is also affected by temperature changes during the day. The key is keeping your eye on the temperature outside and act accordingly.
When the weather hits unseasonable highs, you’ll need to lower air pressure to compensate. During cold spells increasing tire pressure is recommended so your car’s tires can grip the road whatever the icy, cold conditions are.
Last words on the subject: don’t take the easy route and check tire pressure in the comfort of the garage. Tire pressure is meant to be measured in the cold — that means outside driving conditions.
