my car is c coupe. it says the the fron should be 30psi and the rear I think 33 psi.

I took my car to the service the other day and I think they made them all 35psi.
but since then I noticed that when I brake hard from a high speed the car goes to the left.

So, I bought the tire gauge that looks like a pen and used it. it gave me a reading but I really don't know what does it means. and it seems that I can't let the air out with it.

the readings are...

Front left: 1.9 BAR. Right: 2.1 BAR.
Rear left: 2.1 BAR. Right: 1.8 BAR.

and what does that mean in PSI?

thanks.

1 bar is roughly 1 atm...is roughly 14.5 psi.

u'r running a little low...
Front left: 27.5 psi. Right: 30.5 psi.
Rear left: 30.5 psi. Right: 26.1 psi.

this may help u in the future


only in the u.s. where the metric system is not implemented...would've saved nasa a bundle...

thanks

I am running 36psi up front and 32 psi in the rear. I have 245/40/17s on the rear with 7.5 C7 wheel, I run the rears lower so I don't wear the centers.
