328i tires inflation

Guys... I picked up my new 2011 328i non-sport package last weekend. I got 225x45x17 and got about 44 psi on all four tires. The manual recommend 32/39 (sedan) for my car. should I deflate the tires to manual recommendation or should I leave as is? I appreciate all of your input.

44 PSI is quite high... With high temperatures and aggressive driving, you can see that anywhere in the 46-48 PSI range, which is extremely high.

I would recommend lowering them down to 35 PSI and go from there.

Over-inflation can cause uneven wear as well.
