the QX30 Premium AWD I have has the Continental run-flats. What is the recommended tire pressure? Right now, all tires are set to 51PSI. That seems crazy high (it is the max PSI according to the tirewall), but I have never had run-flats before....
51 PSI? Am I high? heh heh.
May explain some of my rattles if so!
the tire placard in the door jam has a lower rating, cannot recall, but not 51PSI!
Thanks for the response. Set to 37 front, and 32 rear last night (warm night). HUGE difference. Some junior at the dealership decided to use the tire MAX PRESSURE recommendation on the sidewall to pump each tire to 51 PSI, hitting 53PSI while driving on the freeway.
Very unsafe and I'll be speaking to the district manager...
You might want to consider getting nitrogen in your tires since it maintains pressure better than the traditional method. The only problem is if you need to top it up, you can only use nitrogen. But there might be something on-the-go you can keep to make that easy.
Thanks for the advice, but I'm the type of guy who checks his tires frequently. This problem was different; clearly ignorance on what tire pressures should be set to and definitely NOT the max PSI on the sidewall! The difference is unbelievable, obviously.
The door on mine says cold psi of 35 front and 29 rear. I have the 18 inch wheels. I find that odd, though, because when I had a screw in one of my rear tires, the TPS warning went off and it was at 28 psi according to the information on the dash.
