Tire Pressure System

[bpa5152]

As you all know the Genesis sedan has a TPS that notifys you when your tire pressure is too low. Well, I lowered my tire pressure to 31 lbs which made my car ride a lot better. However, not that the outside temp is colder (32 degrees) that has lowered the tire pressure and caused the TPS to alert. Everyday the outside temp varies and I can't find a tire pressure that equals a good ride and keeps the TPS from saying my tire pressure is too low. I don't it telling me however, the alert stays on.

Is there any way to turn this TPS off or switch the message on my screen if I lower my pressure for a better ride? Right now my message is off but my car rides rough again.

One other question. When I replace tires do I have to buy tires that work with the TPS? Do I get a constant message if I don't?

No problem if you change tires, but if you change wheels (with new TPMS sensors) they need to be re-synced with the TPMS. I just put on winter tires on new rims - the dealer charged $35 to put the new wheels on and sync the TPMS (I had the tires mounted and balanced at Goodyear before taking them to the dealer). Here are my new rims/tires: http://www.genesisowners.com/hyundai-genesis-forum/album.php?albumid=381

How do I get rid of this message when it comes on my display screen?

If you're getting a low tire warning but the pressures in all four are good, you should take it to the dealer and let him see what the problem is.

Your factory tires have 80% nitro, 20% oxygen. Tire pressure warning will go off when the weather gets really cold with oxygen. I took mine to a dealership and they got rid of the oxygen and put 100% nitro so the pressure warning wouldn't fluctuate when the weather changes.

That sounds like a great idea. However, tires do have a tendancy to lose air after a while. How do you top off the nitro once it loses a pound or so? Isn't it a problem to take it back to the dealer each time to do this? Thanks

My Genesis tire pressure is set to 33 psi, air from a compressor as recommmennded by Hyundai, no warning light except for screw in left rear
already repaired.

My Ford Taurus (old company car rides softer and handles sloppier)

If I wanted my Genesis to ride like a Taurus I would have gotten another Ford

Thank you for your comments concerning my question. However, can anyone tell me how to get rid of the low pressure message on the instrument panel(car with blinking tires) without adding air to those tires? I want to run the tires lower than the TPMS system requires. Is it possible to turn this TPMS warning system off? I don't see this as a benefit.

It is my understanding that if someone had a different set of wheels for winter the tire guy would have to re-program the new sensors, opposite the valve stems, therefore if one was to remove the old sensors, opposite the valve stems, and not re-program the TPMS system, the system would be disabled indefinitely.

There's a 10A fuse for TPMS in the passenger's side fuse panel. You might try pulling that fuse and see if that will completely diable the TPMS, including the warning light. If not, you might be out of luck.

My understanding is that if the wheels do not have sensors installed, or if the sensors have not been sync'ed with the TPMS, the TPMS alarm will display constantly.

Let us know if this works! Thanks.

I'm sorry but I learned in High School chemistry that Charles's Law and Boyle's Law applies to any type of gas pretty much the same. N2 vs Air is not going to change the way gas reacts to temperature in a relatively constant volume.

High School science class aside, 80% nitrogen and 20% oxygen?
Isn't this what we call our atmosphere?

Seriously though, the best reason to keep some oxygen in the tires is to pull a James Bond move and grab a few quick breaths of air if you find your Genesis under water.

I thought if you were underwater you could get a bailout

LOL, not here just keep sucking air out of a few bone they through me!
