What a difference......

I have about 1500 miles on my Genesis and I had suspected the tires were overinflated a bit. So I went and checked with a very accurate gauge and they were set at around 45 PSI give or take a few pounds each tire. Way overinflated. So I set them down to the recommended 33 PSI and I could not believe the difference in ride quality and tire noise. This may have been discussed and if so my apologies but it really made a huge difference. Keep an eye on it because apparently my dealer didn't.

Yeah, inflation makes a big difference. Yesterday, I checked my tires and they were slightly underinflated (31psi). I topped them off to 33, and last night, I swear it sounded like I was driving over a metal bridge on pavement that never used to bother me.

Could be just my imagination, because less than a 10% change shouldn't affect the noise that much. I can only imagine what 45psi sounds like.

This was a common problem,

Dealers were not deflating the tires after shipment, (They were over inflated for shipping).

The tire inflation can be manipulated to cater to the drivers taste. 31 is by no means grossly "underinflated", especially if you live in a warm climate during the summer. Drivers wanting less road feedback may want to consider setting their tires to a lower level. 33 is suggested as a 1 stop shopping inflation. The rule of thumb is for every 10° Fahrenheit change in air temperature, your tire's inflation pressure will change by about 1 psi (up with higher temperatures and down with lower).
