tire pressure

[minivan_don]

ive got 19's on my 07 altima and im trying to figure out the correct tire pressure. in my door say 32psi (no idication of if thats REG psi or if its MAX 32psi) and my tires say MAX 50psi.

at the moment ive got them set @ 32psi but im thinking of lowering it to about 25psi.

I run my landrover and my 240sx with 35psi... the landrover says max 40psi and the 240 not sure ....

the 32 psi written on the door is a recommended not a max, so u are safe using 32 psi,

For the stock tires

With 19's and a little bit shorter sidewall, I'd start off a little higher and drop pressure until the risk and reward intersect. I definitely wouldn't drop it to 25 psi.

ill keep it at 32psi for the moment ... it handles fine the way it is, i just didnt want to over inflate the tires

Correct tire pressure is required to be written on the sidewall of your tire. Your lettering is black, and might be hard to read, but its there. It will say something like "MAX PRESSURE ___ PSI". Fill your tires 10 psi below max, while the tires are fairly cold. See picture below of a general layout of sidewall tire information. The max pressure, in this picture, is written around the center ring of the tire. Hope this helps

Yea, if you fill them at 25psi they are going to be really squishy, might drop your MPG's, and you'll kill them faster as well, not to mention putting yourself at higher risk for tire failure at high speeds. Most tire manufacturers recommend that you increase the tire pressure to over the normal level when you are traveling at speeds in excess of 70-80mph.

Not to mention running lower pressure can result in a dented wheel.... if your after market wheel lip runs pretty far up the sidewall of the tire like mine. Granted you have to fit a decent pot hole.

what?! 10psi bellow max?! my max is 50. but I'm not going to fill that to 44psi! it's going to too hard for my back lol I'm at 33 psi
