Hi there...
sitting here in Germany and wait for my QX. It will arrive here within the next 2 weeks. Now here is my problem: Since there is not a single real wintertire in size 265-70-18 available on the whole planet, I figured that there is the COOPER Discoverer MS snow tire avalable in 275-60-20 now. Ok. So I need
20´wheels now. But what does this tire-pressure-information-thing say to custum wheels? Do I need (new) sensors for new wheels?

Since we don´t have Infiniti dealerships in germany and since Armadas are not know by german Nissan dealers, there is no one to ask this question here...

Thank you in advance for answers...

Stock diameter is 32.8" so you may want to keep that in mind. As for true snows, there are none even close in size made to fit our vehicles. There are A/T and M/T tires. These are typically as good if they have a snowflake rating. Last, get them siped or studded if you are really concerned. Where do you live?

Dedicated snows 1" shorter than stock but in 17", 2" shorter in 18". They will work but aren't ideal.

As for 20" tires, the sensors don't need to be installed. If you put them on, the light will go on occasionally, but that's about it. You can buy sensors, but they are somewhere like $100 each.

What 20" snows are you looking at?

Thanks for your answer.
Im looking at BOSS 311 20/8,5 or Helo Maxx6 or Helo Confusion or Zinik Fablo Z8.
Can I by that sensors with the wheels or do I have to oder them from Nissan/Infiniti.

I believe you need to get them from the dealer, parts dept. I don't have any in mine. The sensors go off if you go below 30psi but I'm running at 37psi so I never get close. I just check them every couple weeks and I've never been low more than a couple PSI. ;)

Just take the sensors out of your old wheels.

I figured he wanted two sets of tires, swap for winter/Summer. This way he wouldn't need to continue to remount the tires. Personally, I'd just do without. I've been checking my tire pressure for 20 years, no reason to stop now. And I don't need to spend $400 to have a computer do it for me. Takes me 10 minutes a year. Bad return on my money. :D

You are absolut right. But have heard terrible storys from Escalade owners who tried to switsch wheels and ran into trouble with this kind of system because it makes alarm without stopping. That would kill me. In my oppinion I would´nt need this whole stuff anyway and check preasur by myself...
Here is the reason wy I want to have wintertires:
(at least it reduces the distance for braking dramaticly)

Nice option. BTW, this isn't an Escalade. The "warning" has no audio. It just turns on a tiny light on the gauge cluster. You don't even notice it and it rarely comes on. Excalade owners are too dumb to notice lights so they need a siren to let them know they need air in their tires. ;)

I hadn't seen the cooper tires. The major sites like tirerack don't have them. The best option I saw was the Bridgestone Blizzak DM -Z3 in 265-60-18. Little smaller than stock but they are supposed to be good in the snow.
Dunlap also has some snows in 275-60-18 but again, they are shorter than stock. ;)

If you have the Nav system, you definitely get a warning, including audio. Scared the crap out of me the first time. BTW, I also make it a habit to check my tire pressures periodically, but we had a small nail in one of our tires, and the tire pressure sensor let me know about it far before I would have noticed it visually. The pressure dropped to 25#'s in about two days, and I don't know about you, but I don't check my tires that often! I think tire pressure sensors are cheap insurance for the unexpected, especially given what can happen with a major blowout. My family rides in this car, anything that increases safety (including manual pressure checks) is worth it in my book.

BF Goodrich T/A KOs are excellent in snow. They are rated better than a M+S (Mud and snow rating) as "Meets RMA definition for passenger and light truck for use in severe snow conditions."
What ever severe snow conditions is, but it looks like your picture might qualify.
I have read reviews both positive and negative for these tires on Tirerack.com and have had 3 sets of them myself. They are definitely excellent all terrain tires and excellent in the snow, although I have a set of studded snow tires that I use on my Pathfinder and was bummed that there are no studded snows available in this monster size for the Armada.
You can get these BFG in a 285/65 18 which is the same diameter as stock.

I have the NAV, i've removed my sensors, and have never had an audible warning. :confused: Maybe this was a change in '05?

Could be. On mine, a loud beeper goes off, and the NAV screen shows the warning. This only happens the first time. The next time the car is started, only the warning screen shows. The screen is very similar to the oil change / tire rotation reminder (the "PIT" symbol with the wrench).

Yeah, must be different. Mine just has a warning light turn on in the gauge cluster that will light up on long trips sometimes. The NAV will show all red for the tires IF I go to that screen. Otherwise, it just asks for agreement to show the map and then works normally without any warnings. I've never had a single warning chime, etc. for the tires. Guess Nissan had a few complaints from '04 owners. ;)

Not to hijack the topic but if you install an extra set of Tire Presure Sensors on a new set of wheels, do you need to get the dealer to program the TPS everything you switch the wheels?
My guess would be that the sensors will send out a generic signal for whatever pressure there set too so nothing inside the truck would have to be changed.


Hey TB,

Mine makes a noise for about 5 minutes off and on then it goes away and just leaves the light on.

maybe you meant 5 times not 5 minutes, b/c this thing is loud when it beeps, I get that beep w/the warning light on the dash every time I have the low air pressure, and I tell you that thing is loud, and definetly will not bare it going off on me for a long time. :eek:

I just replaced my wheels with new ones, with new pressure sensors. My warning light is flashing when I start the car, then changes to solid. Nothing on the NAV system, or any audible warning. According to the manual, this is an indication that the system needs to be reset, and to see your dealer. Anybody with a manual know how to reset the sensors? Will disconnecting the battery for a couple of hours work?

If you replace the sensors, or install wheels with sensors that did not come with your vehicle you will need to get the sensors activated. The dealer can do this, and some tire shops can also.
Look at attachment. Note that is no longer necessary to do this after a tire rotation.

scr38 - thanks for the information, looks like a trip to the dealer is in order. Probably with the first oil change.

Thanks again! Keith
