![]() ![]() However, with run flats, the sidewall vertical compliance is so bad already, running the tires very low doesn’t improve the ride significantly. Higher pressure will give you slightly faster "turn-in" response, and lower pressures will soften the vehicle's transient response because of sidewall deflection, and of course, will give a slightly softer ride. If you prefer slightly "crisper" handling, less understeer at light throttle, and a better safety margin for heaver loads you might try 35F and 37R. Check out the video below for more.As the manual says, the 32F/35R recommended pressures are for a light to medium load (up to 3 passengers). It will benefit your vehicle and your wallet. You don’t want to have a flat tire and then find out your replacement is flat, too. While you’re at it, check your spare tire’s pressure. Rastetter emphasized the importance of keeping dust caps on during winter driving because if water gets into the valve stem and freezes inside the tire, it could cause a flat. When you think you’ve added or let out enough air, check the pressure a few times with the gauge. ![]() If you hear air leaking or spraying out, you need to double-check that the connection between the air hose and the tire’s valve stem is secure. You will hear air quietly enter the tire. To fill the tire, firmly press the air-hose tip onto the valve stem.Do not drive on a flat tire it is unsafe and can damage the wheel itself. A gas station is likely to have one, but not all do. If you don’t have an air compressor at home, you’ll have to take your car somewhere with one. If the reading is lower than recommended, you will need to fill the tire with air.If the tire gauge’s recorded reading is higher than the manufacturer-recommended rating, press the gauge tip on the valve stem until you hear air leak out.The tire gauge should provide a psi reading if the number seems unrealistically low or high - for example, 85 psi or 1 psi – you will need to repeat the previous step, ensuring that the tire gauge’s tip is properly making contact with the valve stem.Using your tire gauge, firmly press the tip of the gauge straight on to the tire’s valve stem for a brief moment.Remove dust caps from the tires’ valve stems.Pull your car onto a level surface in the shade.Rastetter said that if you’ve been on the road a long time and notice higher psi in your tires, don’t let the air out, as the increase in pressure has built up due to the warm, constantly-in-motion tires. Temperature plays a huge part in tire psi, Rastetter said, adding that the most crucial time of year to check pressure is in fall and winter when days are shorter and average temperatures plummet.Ĭheck your tires in the morning before going anywhere, because as soon as you get behind the wheel for an extended amount of time, psi will rise. “Tires are black what does black do? Attract heat,” Rastetter said, noting the importance of finding a shady place to check and fill all four tires. Outside temperatures can cause tire pressure to vary by as much as 1 psi per 10 degrees higher temperatures mean higher psi readings. Tire manufacturers suggest checking tires when they’re cold for the most accurate reading. Tips for Checking Tire Pressure and Putting Air in Your Tires “We’ve found that low-cost digital pressure gauges are very accurate and maintain the accuracy longer, but in extremely cold temperatures the gauge may not show up properly,” said John Rastetter, Tire Rack’s director of tire information services. All will do the job, but you may want to consider the conditions in which you’ll be using your gauge. Prices range from $5 for a basic gauge to more than $30 for one that is digital, has an air-release button - or even talks. There are three types of tire-pressure gauges: digital, internal slide and dial. Unless your tire is visibly flat, don’t judge tire inflation just by looking at it you have to use a tire pressure gauge to get the correct pounds per square inch (PSI) reading. The info is also found in the maintenance or car-care section of your vehicle’s owner’s manual.ĭon’t refer to the sidewall markings on your tires, which in part specify the maximum tire pressure - not the recommended pressure for your car. It displays the vehicle weight restriction and tire information including the recommended tire pressure. To find your tires’ proper inflation level, look for a sticker on the driver-side doorjamb.

Proper tire inflation can significantly improve the fuel economy of your vehicle. CARS.COM - While it may seem like a mundane task, inflating tires is much more crucial to your car than you may think, and it results in a safer and more economical experience on the road.
