It says 44 psi max right on the tires.

Thanks EricL for the official word from Michelin on their recommended tire pressure of 35psi (refer to url above)! Based on other postings here, seems like most of us are also comfortable with 35psi instead of Acura's recommended 32psi.
Note: Went to a Jiffy Lube yesterday for a 5W-20 oil/filter change and they wanted to put 40psi in these tires; not sure where they get their specs.

IMO, I think anyone who recommends a psi other than 32 and persuades someone to change their tire pressure is doing a disservice. After all, it's Acura that has done extensive testing to come up with their 32 psi recommendations. Did Michelin test their tires on a TL-S? I doubt it. Even if they did, Acura knows more about Acura's than Michelin does. No one on this board is a professional. Most professionals will tell you to go with the factory recommendations. That number will you give the best combination of safety and comfort.

I'm not taking sides on this and I don't want this post starting a Firestone/Ford argument. All I'm pointing out is the fact that vehicle and tire manufacturers don't always work together to come up with the OEM recommended PSI.
FYI, I run my TL-S OEM Michelin's at 34 PSI.

Acura probably uses a LOW tire pressure because they want the car to feel smooth, but didn't want to spend the extra money on alluminum suspension parts and a firmer chasis. I seriously doubt its a safety issue. 32 is pretty low IMO. Easy to bend rims that
way (if you live in midwest).

It was according to Boyle's law that when temperature increase, pressure increase. So if your tires are operating, its temperature increase. Same as its pressure. When your car is under normal operating temperature, your tire will be fairly hot (friction between tires and road) and thus, your tire pressure will be increased.
My cold temperature is at 28 psi. However, hot temparture is 36psi. If you guys have your cold tire pressure of 32psi, your tire will most likely be around 40psi under hot temperature.
