Tire pressure

[Retry]

I read the article but I didn't see any specific reference to compensating for the recommended cold tire pressure. The article does state "Passenger cars can also benefit from the more stable pressures", but I took that as a reference to holding a stable pressure during ambient temperature changes, ie. from season to season. Again, when the manufacturer posts a cold pressure PSI, I believe they are taking into consideration what the potential operating pressure will be. My thought process on this stems from a motorcycle tire seminar I attended several years ago at a national BMW rally. I'm not in concrete on this and if find reliable evidence to the contrary, I'll be lowering my pressure.

Hello, currently my tire pressure is low on my R-Spec filled with nitrogen. I also agree that nitrogen is a gimmick based on the complete analysis by Consumer Reports. Since nitrogen is rather expensive, do you see any problems with adding oxygen to increase the tire pressure to its proper state?
Thanks.

There is no problem adding air to your tires that were initially filed with nitrogen. I definitely would not add pure oxygen. Air is approximately 80 percent nitrogen and 20 percent oxygen.

Anyone had there TPMS light come on after 20 minutes of driving? Happened yesterday otw home from work and today otw to work. Checked pressure each time after arriving and they were all 35-37 hot. Light never came on before I installed my HID headlights. Do not see how installing the HID's would cause a sensor malfunction. Any ideas?

This is most likely your problem and is known with aftermarket HID's on vehicles with TPMS. May want to search the forum for HID/TPMS problems on the Genesis.

Scrutiny of the effect on safety of "HID kits" has tended to focus on the dangerous damage to headlamp safety performance (seeing and glare alike) caused by the installation of HID bulbs in headlamps meant to use halogen bulbs. But that's not the extent of the problem. There's a new and very serious threat to vehicle safety posed by "HID kits": Drivers are reporting that electromagnetic and radio-frequency interference from "HID kits" is causing malfunctions in their vehicles' electronic systems including tire pressure monitoring, electric power steering, traction control, electronic stability control, windshield wipers, brake system fault warning, FM radio, and others. For examples, please see here, here, here, here, here, here, here, here, here, here, here, here, here, here, and here.

Electronic driver assistance and safety systems are being factory-installed on vehicles at an unprecedented and accelerating rate. These systems may malfunction in unpredictable and dangerous ways in the presence of electromagnatic and/or radio-frequency interference (EMI/RFI) from "HID kits". The linked examples suggest the effect is not limited to systems involving wireless data transmission. As the prevalence and variety of electronic safety systems increases, the random danger posed by interference from "HID kits" increases in frequency and severity.
