TPMS, the work-around...

Until now, every vehicle I've driven in my adult life has been without TPMS sensors, and I prefer it that way. Having an automotive fabrication background, I can understand the dilemma these engineers face with the NV200. They don't know if you're using your van at max. payload, unloaded, or somewhere in between. So, for liability reasons, they'll set the TPM sensor parameters as if you're hauling at, or near max. payload. I haul a 230# dirtbike and 70# of gear, so I'm going to wear out the centers of any tire I run on the rear if keeping the required pressure they've set. The factory tires are junk, I knew that from day 1. That's usually how OEM tires are and whatever. However, once I put a nice set of tires on, I want to run whatever pressure I want. Having that said, I am NOT claiming that I will perform this modification and I'm certainly am NOT TELLING ANYONE ELSE to do so either. This is simply info that you can use if you so choose.
The NV does not have a smart enough system to know where each sensor is located (for example, some vehicles will tell you actual location of the tire that is low on pressure). Without getting too specific, one could take the spare tire, remove the tire from the wheel, and drill the needed holes to install all 4 sensors in the wheel. Re-mount the tire and inflate between the 44 and 48 PSI. Now, is your average tire shop gonna re-mount that tire on your newly modded wheel with multiple TPMS valve stems? Probably not, just sayin'...

I don't get what you are sayin'...

You are putting all 4 sensors into the spare tire?

The concept is that all 4 would send the needed signal, just not from their original location on the vehicle.

I just realized that I didn't directly answer your question, so yes, all 4 in the spare. Of course, this requires having to run a standard valve stem in the wheels you choose to run on the ground. Your tire shop may or may not approve, so just throwing that out there. I personally have the least amount of other people work on my vehicles, so I typically take my wheels tires in "off" the vehicles anyway for service, do my own rotation, maintenance, etc... so a tire shop will probably never see my actual vehicle.

Ok, I got you now... So, it's just to keep the light on the dash off?

Yeah, not only the light, but the scrolling "check tire pressure" text that keeps the digital display data from appearing.

What if you just removed all the tire sensors and threw them inside the spare tire - without drilling all those holes? Wouldnt that work just as well?

Hmmm might work I suppose but OTOH that the outside of the sensor is exposed to the same overinflation maybe will alter its sensing/reporting? Also what is the spare normally inflated to?

Maybe someone makes a "header" you could mount all the TPMS into and over-inflate to make the computer happy. But I think it's illegal for a tire shop to remove and replace TPMS sensors with non-TPMS valves.

I found out the spinning of the wheel activates the sensors... so they have to be mounted in a spinning wheel.
I talked to a "Nissan Mechanic" online on the "Just Ask" website the other day. He insisted that the sensors only measure a difference between all four wheels and not a specific pressure. So if all tires are at 35lbs then the computer wont kick out an error. He said that just so that the tire pressure doesnt go below 27lbs it will satisfy the computer.
I ran this by my tire guy who I've been buying tires from for 30 years and he says he really doesn't believe him. So I'm going to talk to a service manager monday morning and see exactly what's going on.
I'm up to buying a larger rim with a higher pressure passenger tire if that what it takes. If not, I'll be going through 3 sets of tires a year.

IMO, TPMS systems are overly complicated and add zero benefits.
Folks who are too lazy to check their tires and tire pressure on a regular basis are also going to ignore any warning lites on the dash.

In countries where winter tire/wheel switchover is common the TPMS system adds unnecessary cost and expense.
In Canada it is common to put black tape over the TPMS warning lite on the dash, but as was mentioned, some vehicles have addtional warnings which cannot be taped over.

The drilling of the spare tire and installing all 4 TPMS sensors in the spare will not work on all vehicles. Some guys have also used a steel pressure vessel stored in the vehicle with the TPMS sensors in it.

On my Canadian/ North American Chevy City Express/NV200 it does look like I can simply tape over the TPMS sensor warning lite.
There are no audio beeping and no other messages on the LCD display.
