what tire pressure do you all use for the stock tires for daily driving?

the manual says to set the pressure to 33 psi for high speed driving
(page 5-67)
and then reset it when the high speed driving is completed.

do any of you do this?

sheesh! i'd have to set and reset the tire pressure 10 times a day!

whats it say normal, 32? i just put my tires at 30 and keep them there always.

the reason it would say 33 for "high speed driving" is for fuel economy mostly, adding a couple extra PSI to the tires will make them "bubble" more, and slightly reduce the contact patch, as well as the rolling resistance because the tire will have to "bend" less around the patch ... making it easier to roll, better fuel economy, "high speed" is highway trips if you havent figured it out. this usuall also results in a bit more "pull" from side to side with grooves in the road, and with too much extra pressure can result in weird wear patterns on the tires, i know people that inflate to 35-36 PSI for trips ... they usually do see a return on fuel economy too.

I keep my tires at 32 psi. That's what it says on the stick inside the door so that's what I do.
