treefiddyzee// one of front tire has 28 PSI.but It's going to 31PSI from 28 when car is runing

 

28 is definitely going to set off your warning light.
Pressure definitely goes up with heat and down with cold. Pump them to 35 before driving. If you have to drive to get them pumped up, check the pressure before you leave, then check it when you get to the desination. Add the increase to 35 then when they are cold, they should be at 35. (ie if the tires gain 2 pounds when you drive to the pump, put in 37.)

 

treefiddyzee // the big problem is...I don't know how to add air lol just I need to wait util tomorrow I should go to shop for fix that anyway thank u so much

 

no way..........

 

 

I fixed it!!!! finally I got it!! it was so hard work haha all of tires got 34~35 PSI and

sign is disappear thx everybody~

 

Sell your car before it gets worse!

 

side note: anyone else's Nissan Dealership offer nitrogen to refill tires? Mine says pay a one time fee of $39.99 and then anytime after that it's free! The sign was advertising something like better mpg average and traction or some crap like that?? Just thought I'd ask since I thought of it.

 

16 year old girl, whose first car is a 350z????
did i get that right

 

Does the TPMS readings work in the 07's and 08's? I cant seem to bring it up on mine.

 

harsh but....werd....this guy here

 

That's pressure g-a-u-g-e.

 

u know I don't have any exprience with car before this is first time to have a car

that is why~!I couldn't to add air XD

 

This thread amuses me and scares me all at the same time.

OP, adding air is not an experience that's exclusive to cars... if you ever owned a bicycle or hell even a basketball you'd probably figure it out. Adding air to a tire or whatever is like making love, if you need someone to explain it, you've already failed. But in case you do need instructions, it ironically is similar to sex as well. Find hole, insert, and fill it up.
