I apologize in advance if this has already been asked:

What do you recommend for tire pressure?

I have a bone stock 2013 SV with Sport Package (19" rims). They have Goodyear Eagle RS-A's that say max pressure is 51 psi. Sticker on the driver side door jamb states 33 psi.

I got the car yesterday and the tires were incredibly over-inflated at 55 psi (after getting to temp and the temp outside has been 95+). Ridiculously hard ride, etc. I lowered them all to right around 41-42 psi cold and boy what a difference! Even the little squeak I noticed in the FR side seems to have gone away.

 

The correct pressure is what the driver side door jams states, 33 psi. There are a few here that run at a different pressure as personal preference, but what is on the door jam is the correct tire pressure.

 

the harder the tire the harder the sidewall and less flex in a turn, for a nice ride I do 33psi like Richard66 stated!

 

Don't forget the difference between cold and hot pressure. If you can check your tires early in am before driving that should give you the correct cold pressure, from that reading you should get to 32-33 psi for recommended pressure. If you have driven the car for several miles the heat will expand the O2 molecules and you won't have a true pressure to go off of to start.

 

here in Cali, there's this practice of putting Nitrogen into the tires in place of air. Apparently, there's less leakage and the tires will last much longer due to the Nitrogen not expanding as quickly as air does. I haven't switched over yet, but that's because I wanna get better tires than the RS-A's before I switch out the air.

 

Nitrogen is a lie. Don't pay anything extra for it.

 

So true

When I bought my Maxima new, it had nitrogen prefilled in the tires. Of course I told the dealer that I'm not paying the additional $100 for it since I didn't ask for it. Supposedly it doesn't loose air with the temperate fluctuation like typical air, which is BS because I have to add pressure as the temperature drops in the winter.
