Hey Guys

so as tire safety has been coming up a lot on the news as its one of the things that's most neglected on a car by folks, I figured I'd start a thread on this.

Mine are cold, 34-35 all around...what do YOU have?

JetJock

I use a little less in the rears. The car seems to handle better with more pressure in the heavy front. I never let any tire get more than 1-2lbs below the specs. 34-35 front/ 32-33rear.

Open your drivers door, look down and to the right.
Type-S is 35 front/32 rear
TL is 33/32
For '07 models anyway. Check when cold.

um, well I think all cars tell you what the tire pressure and tire size should be on the door jam... atleast all teh car's I've driven...

and yup I got 35 in front 32 in rear but for some reason when I first get into the car the tps will read 34 in front 30 in back... then after I don't know 10 miles it will read 35f/32r

S PAW 1

I don't get it. Do you think that tire pressures should be different in summer vs. winter? Anyway, the TPS seems pretty accurate on my '07. I probably don't have to tell you this, but pencil gauges, I have found, can be as much as 4 lbs. off. You can get a reading one minute, and come back 10 minutes later, and get a different reading. They just aren't reliable.
A really good gauge is like buying premium gas for your baby. It's worth it.

What annoys me the most is when the TPMS reading on the MID are different, meaning if one tire reads 32, and the other reads 31 / 32 every few seconds, that drives me nuts!

Don't know what quality guage you're using to check at the time of inflation/adjustment, but I'd say the TPMS is pretty close - you are running 34F / 30R. That's the cold tire pressure and that's what you measure.

After 10 miles (really after 1 or 2 miles) the temps build up and that increases pressure. So cold you should be at 35F / 32R and warm, say, ~37F / 34R.

Temperature makes a big difference on air pressure - thus the same tires will rise as the car is driven and will also rise when going from winter to summer.

This is why it always says to measure cold - an increase is expected as you drive.

The TPMS drives my dealership nuts in the wintertime. As the OP said, many people neglect their tire pressures. If your tires are just a few pounds low to start with, a blast of winter cold makes them go low enough to set off the TPMS.
Customers were virtually standing in line last winter in the service dept. with a WTF on their faces.

S PAW 1

Yep!! Every 10 degrees in ambient temperature equals 1 lb. of air pressure. You will, on average, gain 3 psi naturally in your first 5-10 miles.
That's why a good gauge is really important. I personally don't use digital, as I set my tires closer than the 1 lb. increments in most digitals allow. I am pleased with my Accugauge with brass fittings.
My wife says I'm pretty anal about this subject. Last Christmastime I passed out new pencil gauges to anyone I saw with obviously low pressure in their tires (especially SUV's!). Who knows...I may have saved a life

Sorry to double post but no one is answering my thread in the Tire section.

I put air in my tires since my TPMS has been reading 32 front and 30 rears after normal driving. I looked into the manual and it said 35/32. After doing a search someone mentioned about cold tire pressure? So my TPMS should read 35/32 right when I start the car? So what should it read after driving for awhile? I have to drive pretty far to get air in, so I'm not sure how I'll be able to distinguish between cold/hot.

S PAW 1

You and I posted at the same time so........
Yes, your TPMS should read 35/32 before you start the car. You'll gain 3 psi in 5-10 miles naturally (on average). I bought a small rechargeable compressor for about $20-$30, and it works great, especially if your car is garaged.
Suggestion: get a good gauge, and don't depend upon the TPMS IMO.

35 all around

6MT so I running staggerd at 37 Front and 34 rear.

I usually put air at the gas station. They have that tire pressure gauge attached to it.

S PAW 1

You're kidding, right?
Just don't tell me you fill 'em up till they feel "plump".
That will make me go get a scotch on the rocks.

The gas station air pump has the pressure gauge on it, and thats what I went by..well, not exactly. I wasn't sure about the whole cold/hot pressure thing so after I put enough for the pressure gauge to read 35, the TPMS read 39. Being a car illiterate that I am, I took some air out so the TPMS read 35 and 32 in the rear. 'DOH!

My 5AT feels best at 37F/34R or 36F/33R, regardless of season. I'm currently at 36/33.

It is critical to check the cold tire pressure when the weather changes!

Hey folks, I don't mean to sound rude, but do you think Acura just plucked the recommended tire pressures out of the sky? The ABS, and Traction Control all work best when you have the tire pressures at the recommended settings.
You paid $30K+ for this car. Don't neglect the tires!

S PAW 1

By the by, the recommended settings for the TL and the TL-S are different.
Pre'06 6MT's and A-Spec are also different from non A-Spec
Just to add, the alignment settings are also different.

werd I seen the 06 a-spec said to put 32psi all around... I was like what the

RAMEX

That's right Aspec wheels required 39 front 36 rear

Guys....remember tire pressure should always be checked cold. Dont assume driving then heating up the tires will bring the pressure up to what it should be. Get a good digital gage that measures in at least .5lb increments. I checked my tires today....early in the morning with the car in the garage. One tire was 1lb low...the others OK. I keep a tank of nitrogen in my garage...just to make servicing the tires easier. The tank is cheap...the nitrogen free....at my job...the mechanics fill it for me. No need to use nitrogen...just make sure you keep those tires at the proper pressure. It's cheap insurance for your safety.

Where did you see that?
It's not the wheels, it's the suspension set up/tuning
