Introduction & First FNG Question

[SleeperG37]

Hello all,

This is my first post here, and I apologize up front for the remedial post. I have to admit that I'm a newb to Infiniti. I've been an Audi guy for quite some time. My current car is in my sig, but I will be in the new-car market by the end of the year. The G37 sedan is definitely on my short list. I've done a bit of homework on the current G's, and recently got my mother-in-law into an '08 G37S.

Now for my question. She's had the car since Labor Day weekend, and the other night her TPMS alert came on. I tried to find the tire pressures in the computer, but couldn't find them anywhere. The owner's manual was no help either. I've also searched online and here, but no dice. Can anyone tell me if the car comes with this feature? My wife's '08 Tahoe does, so I figured with all the tech the G has, it should have it too. I checked all of the tires manually and found that all were at 30 except the front left, which was at 28. These pressures are extremely low for 19's, which puzzles me based on the car's age.

Again, sorry to ramble out of the gate. Any help would be greatly appreciated. I will be lurking more and more as I get closer to my purchase. Thanks for all of the great content. I look forward to moving in.

my 05 g35x doesn't have a read out on the TPMS... but once you inflate the tire back to the factory recommended tire pressure and drive a short distance it will go off.

My right front was down to ~28 psi last week... inflated it to 32psi (all my tires are at 32psi) drove less than a mile and the TPMS light went off.

Sleeper G37;

I am not sure what the temperature really is, where you are, but in the cold, you will sometimes find the TPMS come on as the air contracts. After a few minutes of driving, once thr air is heated, the TPMS light will go off.

On the other hand, just fill up your tires up to 35 PSI. I suspect this is what is on the side of the door where the manufacturer posted the front and rear tire pressures. In addition, 35 PSI from what i have experienced, seems to be the universally accepted pressure limit for most small to midsized cars. I could be wrong.

[CrackaLackin]

Just fill one of the tires until it explodes. then you will know the right pressure to fill the others

and the replacement you have to buy...

[dusred]

If you've been driving on low profile tires and the TPMS light comes on don't put any air into the tire until the car has sat for at least 15 minutes. Trust me, the G35's look really stupid with the spare tire . Check all of your tire pressures manually and if all are good take it to a dealer.

[RED_DET]

28 psi will set off the low tire light.

[zozoka1212]

As others where saying. There is no read out on the dash. Just alarm. If the pressure is less then 30 psi it will trigger it. I keep them around 35psi and I've only seen the lights on my 07 once. And congrats on her new ride and hope to see you in a g37 sedan here.

Hope this helps.

Welcome aboard!

I agree with the 35psi, all my tires are set to that. I have a G35 so I'm not sure if there is in fact a tire pressure reading on the cars comp.

What colour are you looking at getting?

[Tampa G35 Sedan 6MT]

I guess I'm the only one that inflates the tire to what the tire says is the proper inflation PSI.

I don't recall what the Potenzas are but I think they are like 51 or 40something.

I know my Jeep has 265 75 16 BFG's and they are the same size a dully would use and they get 65 psi. well i only put 60 psi in the tires

this also give you less rolling resistance and better MPG's

OMG!!!! The side wall psi isn't the tire manuf. reccomended pressure. It is the MAX COLD INFLATION PRESSURE.

Yes running the tire at that pressure does reduce rolling resistance and help mpg, but it is not what the car manuf. reccomends you run in the tire.

Plus if you drive at high speeds w/ the tires set to max cold inflation, you run the risk of the tire pressure becoming to high and causing a blow out. Also you cause the tire to bulge in the center of the tread, wearing the center of the tire out prematurely. Which is a problem in the early G's.

Car manuf. do extensive research for tire pressure, reguarding tire quality, wear carricterists (sp), and safety.

[SleeperG37]

Thanks for feedback. IIRC, the sticker did say 35 all around. I run 35/32 in the 19's on my A4, but obviously that's a different car.

It's so surprising to me that a car with that much tech stuffed into it doesn't give you the per tire readouts. The other puzzling thing is the 30 that all of the tires were at just a month after purchase. It's not been cold here in Dallas at all, so the pressure would not have condensed that much. My assumption then is that the TPMS warning comes on at 30, as my MIL said the light didn't go off after she got above 16mph that night.

As for me, I'm pretty much a black car guy, although the new A4 looks great in white. In the G, I'll be looking at Prem, Sport, Nav, and can't decide on X or not. Wife really wants me to get Auto (my first), which I guess I can live with since it's a 7-spd. One of my local dealers finally put up inventory online, but no prices or options lists, just a bunch of stock numbers. Infiniti still has the 35 up on their site though. I'm hoping for info by the end of the month.

[Tampa G35 Sedan 6MT]

You don't need the x in texas lol!

I would get the 2009 G37 Sedan with the S package and the 6MT... You think your A4 is fun... well you are yet to experience the words "Drivers Car!"

Go take a test drive in a 6MT G37 and you will know what I am talking about! The autotragic trans are no fun!

My good friend, Infiniti/Nissan is lousy at wowing their customers with digital gimmickery and gadgetry. All they do is produce a sound and exciting engine and a sound and exciting transmission---period! I like it that way. The technological marvel of their cars reside somewhere in the heart of their computer programs or ECU. Very few cars the size of the G-35 and G-37 can sustain the level of punishment these cars can take and yet last as long as they do.

So, in sacrifice to electronic gadgetry, we are happy campers with a car that has an impressive level of reliability, than your Audi. And, I can bet if we torture your Audi day in day out like many of us do with our G-35 or G-37, I am probabaly very sure problems will arise pretty soon.

I had a friend with a 2001 VW passat or is that what you call Audi's A4, who had his automatic transmission quit at 150,000K with only high way driving---no WOT or full throttle for the most part. This type of problem is unheard of with Nissans and Infinitis, except if the issue was due to manufacterurer's defect or outright abuse and lack of maintenance, and even then, that is very rare.

I can't remember when anyone complianed about an engine problem or transmission problem on this forum that went beyond replacing batteries, cleaning a cold air intake, or replacing an oxygen sensor, or cleaning a MAF, etc. So, if you plan to buy a G-37 or a G-37, you are going to sacrifice electronic gimmickery for reliability.

I know, it only snows a bit of the time here, and we don't really get hurricanes in TX, but AWD is good for dry pavement too. The balance handling (especially in the wet) is very fun and confidence-inspiring. I no doubt would love the 6MT, but alas, the wife is too short to reach the pedals, and doesn't know/won't learn to drive a stick. I know I'll be giving up some fun, but the paddles in the MIL's g37 are a good compromise.

Wow, what a reply. Let's see if I can cover all the points.I wouldn't really constitute pressure monitoring a gimmick. Lane departure, intelligent cruise, etc, I'll agree with. The Infiniti does have some elec/digital items that are not required. The motorized backseat entrance on the coupe and illuminated sill plates are two that come to mind. Every manuf has their signatures or little items they think are important like the active steering or electric tilt/telescope with gauges attached from Infiniti or interior materials, folding rear seats, active suspension, vertical lumbar adjust or above mentioned departure & cruise items from Audi. Acura's known for infinite amounts of tech, while BMW feels an overall smaller car and included maint are important. American companies view size, motor (in most cases), and basement pricing as important. Every firm has its preferences and filter as to what is important to the market.The power, sound, and reliability are three of the biggest reasons I'm looking at the G. I was never arguing the reliability. It’s well-known in Japanese cars (save for the paint, of course)My Audi has been quite reliable overall to this point, and I don't drive easy. I will agree, however, that it is not as reliable. No German is.As a clarification, the Passat and A4 are two different platforms.I bought the A4 for its looks, handling, interior refinement, and ability to mod affordably, which is why I’m looking at another one. I’m looking at the G for the power, reliability, value, and ability to mod, although the breadth of products available is seemingly smaller, and the power mods are more expensive.Pound for pound, the G is a better value than the A4 for the reasons mentioned above. The only real downsides I have for the G at this point are the aforementioned cost of modding, and the fact that they are much more of a commodity on the streets than the Audi, especially the new one. Like I said from the beginning, the G is definitely on my short list for all of the same reasons you all love yours. Only time, availability, and deal will tell where I end up. Thanks again for the insight and warm welcome.

+1 for wives who will not drive stick.

The paddle shifter in the new Gs are great. The Auto shifts faster than a stick possible can. For anyone who sits in traffic for any amount of time an auto is not that bad. Sometimes I like to get in the car and just drive, at least with the new ones you have the option to drive it hard and enjoy it.

As for the electronics in the car. I do not know why they don't have a display for current tire pressure. Other models show them in their respective locations. The light will come on at 28 or a certain percentage below spec. (The actual numbers escape me now) In your area you may want to think about advising the MIL to have the tires filled with nitrogen.

I cannot wait for the new Infiniti models that will feature the seven speed. I have driven a few new Fxs and I really like them the shifting is pretty seemless and the technology behind the shift control is impressive.

I guess I'm the only one that inflates the tire to what the tire says is the proper inflation PSI.

You can do that, but the likely hood of a blowout or structural integrity of the tire is greatly compromised running tires at the pressure level. That exponentially increases your chances of a significant blowout once the tires heat up and the air expands and then what is the pressure level? 60+psi in a lifted jeep really? What load range tires are you using? They may be the same size as a dullie but those tires have steel corded sidewalls.

[Jacko3]

Actually, for the G-37, I found the auto to be just as fun. I think you will like it. After test driving the auto and maual of the G-37, I found myself attracted to the feela nd performance of the auto version. The reverse was the case when i test drove the G-35 auto and manual.

Yeah, I guess the old saying holds true "If she ain't happy..." This would be the first auto I've owned, and while I'm a bit saddened by it, the 60 miles I drive roundtrip each day will be a bit less stressful.

[SteveTheTech]

It's one of the keys to a happy life, I have learned this over the past nine years. LOL it was a long hard road, filled with many nights on the couch.

Of all the automatics on the market now I really like the different shifting modes (d, DS, paddle) and that adaptive shift control and rev matching. You will not be disappointed if you do pull the trigger on one.

Keep us posted

[Beancooker]

I run 42 PSI for what it's worth. .
