Recommended Tire Pressure? Tire installer says 39PSI???
I recently had new Bridgestone Turanza Serenity Plus tires installed on my 2008 Acura RL. I noticed the installer inflated the tires to 39 PSI. I believe the recommended PSI on this car is 32 PSI. I called the installer to find out if I was wrong and they told me that the recommended PSI for these tires is 39 PSI and that I should not follow the Acura specifications since these are not the OEM equipment tires. I've never heard that before I tend to disagree, but wanted to get this groups' thoughts. Should I decrease the pressure down to 32 or stick with 39? I don't want uneven wear on the tires. Thanks!

Isn't door jam for OEM? I'd think the properties of the tires themselves would dictate the best pressure a lot more than the characteristics of the car, no?
Also heard the #1 reason for blow-outs is under-inflation. So ever since hearing that I run 2 PSI over door-jam recommendation - better gas mileage and safer in summer.

The door jam spec should be followed over the tire spec. I will let BDogg confirm, but that is my opinion on the matter.
I think the OEM spec is too low for the RL. It is 32 front/30 rear. I try to keep mine around 35/34 when cold.

More is better, right?
I run mine higher than oem, too.
I took it into the Texaco station ... and had the tires pumped up to fifty pounds each -- which alarmed the attendant, until I explained that these were "experimental" tires.

But fifty pounds each didn't help the cornering, so I went back a few hours later and told him I wanted to try seventy five. He shook his head nervously. "Not me," he said, handing me the air hose. "Here. They're your tires. You do it."
"What's wrong?" I asked. "You think they can't take seventy-five?"
He nodded, moving away as I stooped to deal with the left front. "You're damn right, he said. "Those tires want twenty-eight in the front and thirty-two in the rear. Hell, fifty's dangerous, but seventy-five is crazy. They'll explode!"
I shook my head and kept filling the left front. "I told you," I said. "Sandoz laboratories designed these tires. They're special. I could load them up to a hundred."
"God almighty!" he groaned. "Don't do that here."
"Not today," I replied. "I want to see how they corner with seventy-five."
As it turned out, the Whale behaved very nicely with the altered tire pressures. The ride was a trifle rough; I could feel every pebble on the highway, like being on roller skates in a gravel pit ... but the thing began cornering in a very stylish manner...

I definitely wouldn't run them at 39psi. Honestly, it's really up to you and what you want out of the tire. You can't really go wrong with running them at the OEM specs. Personally, I was running my Conti DW's at about 36psi to try to get a little bit more responsiveness out of them. I frequently check my tread depths across the entire contact patch and they were starting to wear more in the centers so I backed the air pressure back down a little. Again, it's kind of up to what you want out of the tire.
More air pressure will typically give you better gas mileage and more turn in response from your tires. Less air pressure typically creates better overall lateral grip at the limit. As long as the handling feels mostly neutral, (or to your liking), I would suggest monitoring how the tires are wearing across the tread for the first 5k-10k miles. If they seem to be wearing more in the center of the tread back the air pressure off a little bit. If they seem to be wearing more on the shoulders increase the pressure.
Never go off what the max cold psi stated on the sidewall is. This is just the maximum amount of air pressure the tire is designed to be inflated to. It has nothing to do with what those tires should be inflated to on the vehicle they are installed on.

I like to keep mine at:
Spring - Summer: 35psi front, 34psi rear.
Fall - Winter: 37psi front, 36 psi rear.
The reason the psi is up by 2 for the fall and winter seasons is to compensate for the cold weather, which decreases the pressure.

Thanks all for the advice. Per your suggestions I'm going to lower the PSI to 36 and then monitor the tread depth and adjust as needed.
I have noticed the car is much more responsive with the higher PSI, but I don't want to sacrifice longevity for handling. :-)
Thanks,
Brian
