Tire Pressure Recommendations

2015 DCLB w/ 245s

The sticker on my doorsill says 30 which seems pretty low. What's your recommended pressure? What about when carrying weight in the bed and/or pulling a trailer?

 

chalk line test

all trucks are different

 

What's that?

 

Park on level ground and aim front tires straight ahead.

Draw a line completely across the tread.

Pull ahead 2-3 tire revolutions or until the chalk starts wearing off.

If the chalk mark is worn off equally across the width of the tread, the inflation pressure is correct.


If the chalk mark is worn off more in the center than at the edges, the tire is over inflated.


If the chalk mark is worn off more at the edges than in the center, the tire is under inflated.

 

Put a chalk line on your tires. Drive 500 ft. If it's completely gone, you have the correct tire pressure. If it's on the inside only, increase air pressure. If it's on the outside, decrease. Adjust until no chalk is left.
