It is vital to maintain proper tire inflation pressures for 2005 Pontiac GTO tires. Low tire pressure and underinflated tires can lead to uneven and excessive tire wear, poor handling and reduced fuel economy. High tire pressure and overinflated tires can result in reduced traction, poor braking and can even be a cause of a tire blowout. Check tire pressure regularly and maintain correct tire inflation for 2005 Pontiac GTO to enjoy a safe and comfortable drive.

Recommended tire pressure for 2005 Pontiac GTO is determined by the manufacturer based on its characteristics and original equipment tire sizes. You can find 2005 Pontiac GTO recommended tire pressure in owner's manual or on a tire placard on the side of driver's door or door jam. 2005 Pontiac GTO tire inflation will be listed in psi (pounds per square inch), bar or kPa (kilopascals). Keep in mind that tire inflation listed on tire sidewall is the maximum air pressure the tire can hold to carry its maximum load, and not necessarily the recommended tire pressure for 2005 Pontiac GTO. Your 2005 Pontiac GTO may also have different recommended tire pressure settings for front and rear tires, especially if equipped with staggered tires.

To check 2005 Pontiac GTO tire pressure you will need to know its recommended tire inflation and a tire pressure gauge. Check tire pressure when tires are "cold" using quality tire pressure gauge. Adjust 2005 Pontiac GTO tire inflation to the recommended tire pressure settings as needed by adding or releasing air.

If you replace 2005 Pontiac GTO original equipment tires and switch to different tire size, make sure to follow guidelines for the application of load and inflation tables to find proper tire pressure for new tires. Always refer to the 2005 Pontiac GTO owner’s manual for any specific safety advice regarding the application of replacement tires.

2005 Pontiac GTO tire pressure fluctuates with ambient temperatures, so during winter when temperatures drop tires may lose approximately 1 psi of air pressure for every 10 degree Fahrenheit decrease in temperature. Some vehicle manufacturers may recommend inflating tires 3 to 5 psi above the recommended tire pressure settings to compensate for lower temperatures during winter. Make sure to check tire pressure more often in the winter to keep tires properly inflated for a safe ride on snow and icy roads.

If your 2005 Pontiac GTO is made after 2007, it should be equipped with tire pressure monitoring system that uses tire pressure sensors to alert the driver when tire pressure is low. If 2005 Pontiac GTO low tire pressure warning light is on, check all tires for low air pressure and inflate as needed. If you need to reset TPMS, refer to owner's manual on how to reset 2005 Pontiac GTO tire pressure monitoring system.
