![]() You should check (and fill if required) your tire pressure at least once per month during periods of colder weather and perhaps once every other month during periods of warmer weather. Most gas stations also have “do it yourself” stations for measuring tire pressure. You can pick one up at most auto parts store. The easiest way to measure tire pressure, is to use an air pump with a tire pressure gauge. To figure out what that specific number is for your vehicle based on local weather conditions (i.e., average temperatures during different seasons), check online resources like TireRack and TireCheck. During warm summer months, aim for about 3-5 pounds per square inch (PSI) below the recommended levels. In general, optimal tire inflation levels vary depending on where you live, as different temperatures require more or less air.ĭuring cold winter months, aim for about 3-5 pounds per square inch (PSI) above the recommended levels. Outdoor Temperature Changes Optimal Tire Pressure ![]() Once you have established what pressure is best for your car, you can use a tire pressure gauge (sometimes called a PSI gauge) to determine if your current levels fall within that range. Look for a chart that details optimal pressures for different tire sizes and make sure yours fall within those ranges. You can also search for a specific make and model of a car using keywords like car tire pressure or car tire size online. Your manual will detail what level of inflation is optimal for your vehicle’s tires based on whether you are driving in high temperatures or on rough terrain. It’s common for different makes and models of cars to have slightly different guidelines about tire pressure. How To Determine Tire Pressuresįirst, check your vehicle manual or door jamb. So, before you hit the road, make sure your tire pressure meets industry recommendations. Given that roughly 30% of drivers don’t even bother to check their tire pressure regularly, odds are you drive on misaligned tires way too often. It’s actually been shown that driving with under-inflated tires increases your risk of having a fatal accident by more than three times.ĭriving with under-inflated tires also significantly increases the wear of your tires, leading to you having to spend a lot of money buying new tires sooner than what you would actually have to. This is dangerous during all circumstances, but especially when driving in rain or snow. Under-inflated tires also increase your stopping distance by about 10-30% (the exact number depends on how much they’re under-inflated of course). ![]() Studies have shown that you’ll waste an average of $200 per year (for the average yearly driving distance in the US) in extra gas when driving with below ideal tire pressures. In fact, under-inflated tires can have a significant impact on fuel economy. If anything, it’s been shown that driving with under-inflated tires are worse overall than driving with over-inflated tires. But doing so for too long will cause unnecessary stress on your tires, leading to excessive wear and possible blowouts.ĭriving with incorrect air pressure is bad for fuel economy, as properly inflated tires create less rolling resistance, helping your car to consume less fuel. Sure you’ll be able to drive your car for a while with slightly under, or over-inflated tires. ![]() Why It’s Important to Drive With Ideal Tire Pressureĭriving with ideal tire pressure is important for safety, car/tire longevity and fuel efficiency. Read on to learn more about the correct air pressure for your car tires, and how to find measure it. Add 3-5 PSI during cold weather and remove 3-5 PSI during warm weather. Most car manufacturers recommend between 33-36 PSI for passenger cars. The correct air pressure for your car tires are what’s stated in the driver’s side door jamb or in your owner’s manual. So, you have new tires installed on your car or truck, and you’re unsure what the correct air pressure should be.
