Tyre Pressure 

Understand Tyre Pressures For Your On & Off-Road Driving Situations

OVER INFLATION

Too much air in the tyre, resulting in premature wear in the center of the tread.

AIR PRESSURE

The amount of air inside the tyre pressing outward on each square inch of tyre, which is expressed in pounds per square inch (psi), bar or kiloPascals (kPa), the metric designation for air pressure. Airtight Synthetic Rubber.

Formulated with virtually impermeable butyl rubber, this material replaces the inner tube in modern, tubeless tyres. Check you air pressure monthly, as some air loss occurs over time.

 

COLD INFLATION PRESSURE

The amount of air pressure in a tyre, measured in pounds per square inch (bar) before a tyre has built up heat from driving.

 

INFLATION

The act of putting air into tyres.

 

KILOPASCAL (KPA)

The metric unit for air pressure. One bar is equal to 6.9 kPa.

 

MAXIMUM INFLATION PRESSURE

The maximum air pressure to which a cold tyre may be inflated; can be found molded onto the sidewall.

PSI

Abbreviation for pounds per square inch, which is the automotive industry's measurement of the pressure in a tyre.

BAR

The bar is a metric unit of pressure. It is defined as exactly equal to 100,000 Pa, which is slightly less than the current average atmospheric pressure on Earth at sea level.

WHAT TYRE PRESSURE SHOULD I INFLATE MY TYRES TO?

The vehicle manufacturer selects the size and type of tyres for their vehicles. They perform the necessary testing to establish the vehicles' optimised operating tyre inflation pressures which can be found on the vehicle placard (located on the inside of the driver's door) and in the vehicle owners' manual. If the tyres on your vehicle are the same size as the original equipment tyre, inflate them to the pressures indicated on the placard.

If the size of the tyres is different than the size indicated on the placard, please contact your closest authorised BFGoodrich dealer for a pressure recommendation.
