Cold Psi

…its tire pressures first thing on dark, cold mornings, the influence of attached garages or higher ambient air temperatures later in the day often means that drivers are actually measuring tires that are not completely cold. In this case the 3-5 psi higher recommended inflation pressure increase…

…to experience "hot" tire pressures that are up to 5 to 6 psi above the tire's recommended "cold" pressure during the day if the vehicle is parked in the sun or has been extensively driven. Therefore, if the vehicle's recommended "cold" inflation pressures correspond with the tire's maximum inflation…

…Increase.* Set 2 psi above vehicle manufacturer's cold inflation recommendations when installing new tires or if the vehicle has been parked in the shade for a few hours. Tire Heat Generated While Being Driven (or at speeds of less than 45 mph).* Set 4 psi above vehicle manufacturer's cold inflation…

…after moving the trailer from a cool building into the sun's radiant heat. Setting tire pressures cold in the morning simplifies the job. As a rule of thumb, add four psi to the recommended cold inflation pressure if the tires are already warm/hot to the touch. Special Trailer (ST) Tire Replacement…

…10 psi may look exactly like one that's properly inflated. And there's no better way to check tire pressure than using a tire pressure gauge. We sell tire pressure gauges made by Accutire and Intercomp for all needs and budgets. Don't forget to check the pressure when the tires are cold.…

…is fully warmed up to working temperature and that the difference between "hot" and "cold" tires can be very significant, typically 7 psi. Set-up procedure: set the tire pressures when cold to approximately 6 psi less than the required operating pressure. Drive the car on the circuit for 3 to 4 laps…

…is about -50 Fahrenheit&which results in a potential loss of about 5 psi as winter's temperatures set in. And a 5 psi loss is enough to sacrifice handling, traction, and durability! Additionally, the difference between cold nighttime temperatures and hot daytime temperatures in most parts of the…

…and 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,…

…58.5 psi (23.5 psi high blamed on a faulty air pump pressure gauge at a gas station). While maintaining correct tire pressures is a common problem, these results emphasize how little importance drivers place on maintaining them. The Tire Rack recommends that all drivers check and adjust cold tire…
