I believe the label states 36 psi in all 4 tires cold.Just wondering. ... what tire pressure to pump these tires to. The Bridgestone stamp says 50 max psi, but I noticed on my VIC, they're only 39-40 psi. I appreciate any help with this.
The tpms don't send a signal updating the pressure when driving unless over 20 mph. They only send a signal infrequently (I forget how often) when not driven. If you go out in the morning to check tires and hit DIC to read them before driving it will be from the last time it updated sometime overnight. I drive around neighborhood at 25 mph for a few minutes for them to send a signal a couple times and then find that on both Yukon and Enclave they match my ever trusty antique Dill pencil gauge!Correct tire pressure is 36 lbs cold check before you drive with a pencil gauge, get one from Sears accugauge is the name I think. The dash read out is off I did mine with a pencil gauge to 36 lbs it showed 35 in 3 tires and 34 in one. I am going to have mine relearned at dealer. Both my Camaros never read correct, the Corvette does go figure.
The reason for high readings cold is they are shipped with 50lbs because of all the tying down on transportation. Your dealer tech never adjusted the tires my car was driven and hot when he went to adjust told him to leave at 39 so I could check cold and bleed down to proper pressure. Proper pressure saves the tires and gives better ride.
36 cold all the way around, bump the rears to 39 if you have a large load.
No need to ever fill a tire to it's max, unless you are looking for leaks.
Tires are usually overfilled for shipping. Dealers hardly ever correct it. Go by the manual for best performance.Mine are set to 44 all the way around. The dealer had them set that way when I picked it up and I like the way it feels at that pressure. I realize the sticker on the door specifies 36, and I have always believed the auto companies set the recommended pressure lower than what the tires can handle so that the ride quality is softer.

Mine came from the Dealership with Nitrogen in the tires. It has a green sticker on the windshield with white lettering the states: "you are riding on TIRESAFE NITROGEN"
I noticed the valve stems have a cap that has a green ring around the cap and: "N2" on each cap. I was told by the dealer that the nitrogen keeps the pressures from fluctuating from temperature changes alot better than air. Also, according to the dealer, it seems to not leak as fast as air.
I have 1000 miles on the car and during that time the temperture has been down to 21 deg. and up to 76 deg. During that time, I have noticed the tire pressures have only fluctuated by 1 psi so far.
The dealer said to bring the car back anytime and they would add nitrogen whenever it's needed for free.
