Tire pressure settings for daily driving

I currently have all four tires set to 38 psi for daily driving due to better gas mileage with higher psi. I just want to see what other owners are

Default Tire pressure settings for daily driving

I currently have all four tires set to 38 psi for daily driving due to better gas mileage with higher psi. I just want to see what other owners are setting their tire pressures at. I'm aware that the recommended tire pressure is lower than what I have mine at.

You should follow the manual if you want your tires to last. I over inflated my 350z tires and the middle wore out quicker.

^Not to knock you, but 6500 km isn't going to show a drastic amount of wear at any pressure.

OP. I'd suggest running them at 35. I'd be willing to bet that you're only getting slightly better mileage by running them high and the rate that your tires wear out will probably outweigh that gain in mileage.

To check this, I would also suggest getting a tire depth gauge. This way, you're not "eye-balling" the tread wear.

OK, what about aftermarket rims and tires with lowerd suspension? Would that change psi requirements? i have hankook v12 255/35/19 and 305/30/19? rims and 9inch wide front 10 inch wide back. springs are eibach.

My mechanic says 38psi is best from his experience for my car.

no. but manufacturers recommend tire pressures based on comfort so usually too low for my driving needs...thus i use 36.5psi in the summer regardless of stock or aftermarket.

anybody check their tire pressure when tires gets warm?
I've noticed my tire pressure increases 2-3 psi after aggressive driving. So I had my tires at the 35 PSI recommended pressure at night, then after some driving it goes up to 38psi.

I was told that the air you fill in to the tire has part oxygen and oxygen expand with increasing temperature. That's why some people fill their tires with only nitrogen?

No, nitrogen in tires will keep them inflated at the correct psi for longer as it is more difficult for nitrogen to escape the tires thus losing pressure. When measuring air pressure and filling your tires you should always do so when the tires are cold because, as you said, air expands and psi goes up once the tires get warmed up.

Don't you have less contact patch if over inflated, hence, more uneven wear and poorer traction? That should lead to worse gas mileage, not better...

To the OP, 35 psi cold is probably fine -- don't forget they will expand somewhat with heat as you drive.

From what I've heard, the higher the psi in your tires, the better gas mileage you will get.
