Correct tire pressure
Driving on any tire that does not have the correct inflation pressure is dangerous.
The correct inflation pressure for your tires may be found in the vehicle owner's manual.
An underinflated tire may not carry the designed load and builds up excessive heat that may result in sudden tire destruction. A loss of fuel economy may also be experienced.
Over inflated tires may suffer reduced grip and may wear out the tread centre. Over inflated tires may be more prone to puncture and damage of the sidewalls.
Refer to the vehicle owner’s manual for the recommended operating inflation pressures. These pressures must be maintained as a minimum.
If you are replacing the original size tires with tires of a different size, you must consult a tire dealer or your vehicle manufacturer to determine the correct inflation pressure for your new tires. Checking Tire Pressure Check your tire inflation pressures, including the spare, at least once a month and before going on a long trip. Tire pressure should be measured when tires are cold - that is, they have not been driven on. Otherwise, your tires may have heated up, increasing the air pressure inside them by several pounds. This is normal. Never "bleed" or reduce the air pressure in a hot tire. Failure to maintain correct inflation pressures may result in rapid wear and uneven tread wear, improper vehicle handling, reduction in fuel economy and excessive heat build-up which may result in tire failure. (Evidence of air loss or repeated underinflation requires tire removal and expert inspection.)
