They fall faster in the cold
In winter, there is a driving myth that underinflated tires are better for driving in snowy conditions because then the tires have more contact with the ground. While this isn’t technically wrong (sometimes it’s even useful, for example, too get out of deep sand or muddy ruts more easily), it’s actually never safe to intentionally drive with low tire pressure, even in heavy snow and low temperatures.
Driving with underinflated tires multiplies the likelihood of a crash in the cold months as well, according to a study by the US National Highway Traffic Safety Management. Only well-inflated tires
move better through the snow, save fuel
and last but not least – they last longer.
Car tires on most models are usually inflated to a pressure of 2 to 2.4 bar, and the recommended figure for a given model is writen on a special sticker somewhere on the car (usually on the inside of the driver’s door).These manufacturer-specified values should be used year-round because there are no different figures for summer and winter.
However, no one denies that the outside temperature still affects tire pressure. That’s why tires need to be checked and pumped up more frequently enough in the winter than in the summer months. All this is done so that it can
to maintain the ideal pressure,
which is one of the most crucial factors in driving safety.
In summer, there is no such need, as the molecules of the warmer air in the tire move faster and “collide” more with each other, increasing the pressure in the tire to the required level. when the temperature drops, air molecules slow down and “stick” to each other, resulting in a drop in air pressure
In practice, many tire manufacturers calculate that tires lose 0.06 bar for every 10 degree drop in outside temperature. Likewise, parking the car for an extended period of time in winter usually greets the owner with partially deflated tires.
If the car has a tire pressure monitoring system,the warning light will activate when the pressure drops by at least 25 percent. This little innovation in the automotive world is especially useful for keeping track of tire pressure in cold weather.
the tires are checked even after the car is parked
for only a few hours (driving increases the air temperature and thus the air pressure in the tires) to obtain the most accurate value of the loss compared to the prescribed one.
It is best to check tires once a month, as under-inflated tires with a lower side profile do not always show the drop in pressure as much as those with a higher profile.
Other signs that your tires might potentially be underinflated are if the steering wheel starts to shake, if only one tire “pulls to the side” or if it takes “more time” when braking.

Interview: The Truth About Tire Pressure in Winter Driving
Time.news Editor (TNE): Welcome to our special segment, where we tackle common myths and misconceptions in the world of safety and technology. Today, I’m joined by Dr. Sarah Thompson, a leading expert in automotive safety and tire technology. Welcome,Dr. Thompson!
Dr. Sarah Thompson (DST): thank you for having me! I’m excited to discuss an important topic for winter driving safety.
TNE: Let’s dive right in.There’s a prevalent myth that underinflated tires perform better in snowy conditions because they provide more surface contact with the ground. Can you explain the reality behind this?
DST: Absolutely. While it’s true that having more surface area can definately help in specific scenarios, like when trying to get out of mud or deep sand, driving with underinflated tires is never safe, especially in winter conditions.underinflated tires significantly increase the risk of accidents. A study by the US National Highway Traffic safety Management shows that they are more prone to losing traction and handling issues, which can lead to crashes.
TNE: that’s eye-opening! so, you’re saying that keeping tires at the recommended pressure is essential for safety?
DST: Exactly. Properly inflated tires not onyl provide better handling and traction on snowy roads but also enhance fuel efficiency and extend the tire’s lifespan. They ensure that your vehicle can maneuver effectively through poor conditions,which is crucial for winter driving.
TNE: What about the cold weather itself? How does it impact tire pressure?
DST: Great question! Cold temperatures can cause tire pressure to drop. For every 10 degrees Fahrenheit decrease, tire pressure can decrease by about one PSI. That means as the weather gets colder, drivers should check their tire pressure more frequently to ensure they are at optimal levels.
TNE: It sounds like regular maintenance is key.How often should drivers be checking their tire pressure during the winter months?
DST: ideally, drivers should check their tire pressure at least once a month and before long trips. It’s also a good practice to do so when the tires are cold, meaning the vehicle hasn’t been driven for a couple of hours. This is when the tire pressure reflects its true state.
TNE: Those are excellent tips! And if someone does find their tires underinflated,what should their first action be?
DST: First,they should inflate the tires to the manufacturer’s recommended pressure. This can usually be found on a sticker in the driver’s side door or in the owner’s manual. If they’re unsure about how to do it, most gas stations have air pumps, or they can ask a professional for help.
TNE: Fantastic advice! One last question: Are there any additional winter driving tips you would recommend apart from tire maintenance?
DST: Yes, definitely! Drivers should also ensure their windshield wipers are functional, their antifreeze levels are appropriate, and that they have a winter emergency kit in their vehicles.This kit should include items like a blanket, flashlight, water, and non-perishable snacks, in case they get stranded.
TNE: Dr. Thompson, thank you for sharing your insights on tire safety and winter driving. Your expertise helps clarify a lot of misconceptions around this important topic!
DST: Thank you for having me! It’s crucial that we continue to spread awareness about safe driving practices, especially in challenging weather conditions.
TNE: Absolutely! And to our readers, remember to check those tire pressures and drive safely this winter. Until next time!
