Hi all,

I was wondering what the tire pressures were set to on you respective RX's. Mine started out around 37-39 back on Nov 25th and has gone down to around 36 all around. I remember seeing a screenshot of someone's RX on here and it was in the 40's. I don't have the car or manual near me at the moment but what are y'all inflated at?

Thanks,

You need to use the pressure indicated by the placard on the drivers side pillar when you open the door. Some apply a little more for better mileage, some less. They are cold tire pressures.

 

Speaking of tire pressure... Mine came filled with nitrogen for which I really did not see any benefit in my last vehicle.

Anyone else?

 

Not sure if mine has nitrogen or not. The only advantage I know of is that the atoms are larger and your tire pressure will not need topping off as often. Other than that not much advantage.

 

Yes, they made a big deal about this when I bought my previous RXh. I think within 1-2 years in, the tires needed topping off regardless. The car did not get driven that much and it mostly sat in the garage.

I don't think I got charged extra for it this time around, but if they did, I would certainly decline it.

 

what I learned is whatever is on the door sill, add +5 to it.

This compensates for heated tire pressure while driving to where you need to add air.

Remember, unless things have changed, they give you the recommended COLD tire pressure which is when the car hasn't moved in many hours.

This is for tires inflated with nitrogen and maybe even add a few more with regular air.

 

Mine came from the dealer at 35 - 37 (depends on the temperature). They are the Michelin Premiere XLTs, IIRC (on a 450H with the f-sport package).

 

1-2 years without adding any air is pretty darn good.
