| In the manual and on a lot of websites, I found the suggested tire pressure to be 32 psi. I just bought an 06 MDX 2 weeks ago, and just decided to check the tire pressure today. It was 37 psi. Is there any reason why the dealer inflate 5 psi over the suggested tire pressure? Does it reduce road noise? improve gas mileage? better handling? what is it? And on a 300-mile road trip, should I inflate the tires more or leave it at 32 psi? |

Did you check the pressure when the tires were cold? (MDX not driven)
I keep mine at 34 and check in the AM before driving. I do find that if I set a 34 in the winter when its cold then in the summer the pressure can be more than 34 cold. |

I kept my tires at 38 psi. It rode a tad bit harder, but the handling was firmer, with less tire squeal for hard cornering. I think gas mileage was a little better too.
You can experiment for yourself between 32 and 38 to see which you like best. |

Simple, neither you nor the dealer knows how long the vechicle will sit on the lot. By over-inflating the tire from the factory, they will not need to constantly check/inflate the tires prior to delivery. You just bought your Mdx, care to guess how long it's been on the lot ? You can check the build date by looking at the label on the driver's side door jamb - there should be a month & year along with other data. My local dealer has over 50+ Mdxs on the lot, can you imagine the cost & labor to check each tire for pressure every week . . . |

32 psi is the recommended tire pressure. Some members have even reported driving their new MDX's home from the dealer with tires inflated to as high as 44 psi. Your 37 psi inflated tires would not be too out of the ordinary. This suggests that you should check the tire pressure in your MDX personally at least once a month. Use a calibrated pressure gauge. I have found 35 psi to be optimal to give the best ride for my MDX. You can experiment with what is best for you and your driving conditions. Obviously, properly inflated tires will give you better handling and gas mileage. Enjoy your new ride.:29: |

| Most tire pressure guages are only guessing, too. Try it out- I've found 3 to 6 psi difference between some of my guages. I even "standardized" one by comparing it to a regulated pressure supply at 100 psi; at 30 psi it was still off by 2 or 3 psi. |

Not that simple really....a good dealer would check the tires and set them at the recommended pressure, 32 PSI, before it leaves their lot! It's part of the inspection that is done to make sure that everything is working properly.
That being said, I have found that 34 to 35 PSI works best for me. Anything more and you risk premature wear on your tires. 40 + PSI is WAY too high and possibly dangerous! |
