Cold inflation pressure is the inflation pressure of tires as measured before a car is driven and the tires warmed up. Recommended cold inflation pressure is displayed in the owner's manual and on the Tire Information Placard attached to the vehicle door edge, pillar, glovebox door or fuel filler flap. Cold inflation pressure is a gauge ...
This measurement of tire inflation pressure should be made at least once a month. Since heat in the tires from driving can impact the temperature a lot, accurate readings can only be obtained when the tires are cold - that is at least three hours after the vehicle has been driven or driven less than 1 km (1/2 mi) since cold - tire pressures ...
Unfortunately, these cold temperatures can affect the mechanics of your car, from low tire pressure to dead batteries. Here are a few pointers to help keep your car functioning as the temperatures ...
Reducing tire pressure also reduces the extent to which the tires grind against loose surfaces, significantly reducing dust and silt. Another function of CTIS is to maintain tire pressure if there is a slow leak or puncture. In this case, the system controls inflation automatically based on the selected pressure the driver has set.

A tire-pressure monitoring system (TPMS) monitors the air pressure inside the pneumatic tires on vehicles. [1] A TPMS reports real-time tire-pressure information to the driver, using either a gauge, a pictogram display, or a simple low-pressure warning light. TPMS can be divided into two different types – direct (dTPMS) and indirect (iTPMS).
The steering effort depends on the downward force on the steering tires and on the radius of the contact patch. So for constant tire pressure, it goes like the 1.5 power of the vehicle's weight. The driver's ability to exert torque on the wheel scales similarly with his size.
Vehicle dynamics is the study of vehicle motion, e.g., how a vehicle's forward movement changes in response to driver inputs, propulsion system outputs, ambient conditions, air/surface/water conditions, etc. Vehicle dynamics is a part of engineering primarily based on classical mechanics.
Atmospheric pressure, also known as air pressure or barometric pressure (after the barometer), is the pressure within the atmosphere of Earth. The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa ), which is equivalent to 1,013.25 millibars , [ 1 ] 760 mm Hg , 29.9212 inches Hg , or 14.696 psi .
