When I recieved my car from the dealer, the tire pressure sensor showed that the air in each of the wheels were off. I would have thought that the dealer would have put the right amount of air in, but oh well..

My question to you guys is what is the optimal amount of air to put in? I've heard that you can put more or less air in to change ride/handling characteristics?

Thanks in advance.

look at the sticker in drivers side door jam.

Im pretty sure that the correct tire pressure for our cars is 35psi in the front and 32psi in the rear. Maintaining the correct tire pressure can be challenging, it all depends on tire temperature for a hot tire you should always add 4 psi (heat expands and cold contracts). keeping the correct tire inflation pressure helps tire performance and fuel economy. Correct tire pressure allows drivers to experience tire comfort, durability and performance designed to match the needs of their vehicles. Tire deflection (the tread and sidewall flexing where the tread comes into contact with the road) will remain as originally designed and excessive sidewall flexing and tread squirm will be avoided. Heat buildup will be managed and rolling resistance will be appropriate. Proper tire inflation pressure also stabilizes the tire's structure, blending the tire's responsiveness, traction and handling.

id do 35 cold in the fronts and 32 cold in the rears. I have an AT BTW.

33 front / 32 rear

FYI, every 10 degrees F of ambient temperature drop will lower the reading of your tires by 1 degree F.

That's not enough to explain poor preparation by the dealer. But like others have stated, 35/33 is what Acura recommends. I set mine at 36/34 because I feel it's a little more precise in the way the car handles.

Do our neighbors to the north use PSI or KPA or some other measure of pressure?

The air pressures recommended by Acura are along these lines for the 17" wheels:
2005 5AT: 32F/32R, 2005 6MT: 35F/32R, 2006 5 AT: 33F/32R
I think 39F/36R is recommended for the 18" A-Spec wheels.

I have no idea what Acura recommends for the '07 TL or TL-S, so >
Check your driver's door sill plate for the recommended COLD tire pressure; the recommended pressure for all tires in your model year are on the last page of the owner's manual. The recommended tire pressure is a starting point-- don't go below it, and don't run at more than 40 PSI measured COLD. You can adjust pressure within that range for whatever feels comfy. For example, my 2005 AT is run at 36F/33R to decrease understeer; the steering response/road feel are also better than 32/32 without any objectionable change in ride.

The '07 recommendation, for ALL model TLs, according to the manual, is 33psi front, 32psi rear.

Now the question is, should we trust the in-dash reading? Mine read 36 on all 4 after sitting in the garage all night (temp about 40F) and 37 during a drive to Santa Fe (temp there about 30F). When I checked it with two different gauges, one a pencil type and one a dial type, the tires registered about 3psi higher. Any Acura service techs reading this?

Just purchased a 2007 TL Type S. My manual (last page) says 35 psi front and 32 psi rear.

I believe the Manual also states not to rely on the TPMS. Use the good old fashion way.

I checked my door today for the correct pressure since it has been bitter cold here in New England and my TPMS sensors were blinking this morning. The door jamb says 33F 32R COLD..........ok so what does that translate in terms of warm? As i drove home tonight the pressure went from 27 cold to about 30 warm.........I kicked them all up to 37 warm and will check it out tomorrow to see what they register cold.

Worse comes to worse I let some out in the morning.....

Exactly, i put in 33 in the front and rear. When i got it, the dealer had like 23 and turning the steering wheel was one heck of a workout. Well i got it used, so i guess, he didnt want me to notice the rattles.
