The recommended tire inflation pressures are on the tire information label on the driver side B-pillar.
Check and set the tire pressure at the ambient temperature in which you are intending to drive your vehicle and when the tires are cold.   See   Tire Pressures
Note:   Check your tire pressures regularly to optimize fuel economy.
Only use approved wheel and tire sizes. Using other sizes could damage your vehicle and could make the National Type Approval invalid.
Installation of any tires that are not the original equipment tire size can cause the speedometer to display incorrect vehicle speed.
