Snow Tire Psi

…each tire. And, since many vehicle's owner's manuals recommend operating winter tires several psi higher than recommended, read "Higher Tire Pressures for Winter Driving." Snow tires are soft. You'll want to rotate them regularly and usually more often than your all-season tires. If you're…

…greater than 45 mph).* Set 6 psi above vehicle manufacturer's cold inflation recommendations. Do Not Release Hot Tire Pressure if any of these variables could be the cause of measured tire pressure exceeding the maximum psi branded on the tire's sidewall by the 2, 4 or 6 psi indicated above for the…

…the inconvenience of standing out in the cold and snow of winter often leads to neglect when the tires need the most attention. For every 10 degree (F) change in outside temperature, your tires' inflation pressure will change about 1 psi. In most parts of the country, the typical difference…

…especially those made after 2010, tire pressure is monitored based off of rotational speed. When a tire loses air pressure, the rotational speed of that tire is changed, and while 1-2 psi will not make a large enough difference to trip the system, a loss of perhaps 5-10 psi will. Once the difference…

…Email Page to a Friend Winter / Snow Tire Tech: Higher Tire Pressures for Winter Driving Several vehicle manufacturer's owner's manuals recommend operating winter tires several psi (typically 3-5) higher than their recommended pressures for summer and all-season tires. While none of them actually…

…the tires under load against the machine's rollers to simulate real world driving. We monitored the changes in tire pressure, and our test tires were inflated to 15 psi, 20 psi, 25 psi and 30 psi. Running them all under the same load, the air pressure in all of the tires went up about 1 psi during…

…1 psi per month regardless of temperature. This means that if you had set your tire pressure at 36 psi on a 70 degree summer day (six months ago) and the pressure has since dropped to 30 degrees, your tires at this moment could have as little as 26 psi in them. Checking your tire pressure…

…new winter / snow tires broken in before the snow begins to fly. New winter tires begin with deeper tread depths and more open tread designs than the tires used during the rest of the year. While the extra tread depth allows new snow tires to provide more traction in deep snow, it also contributes…

…must be used when recommended cold tire inflation pressures exceed 65 psi. High-pressure snap-in valves for .453" rim holes allow a maximum cold inflation pressure of 80 psi while those for .625" rim holes allow a maximum cold inflation pressure of 100 psi. Typically used in steel wheels,…
