My new wheels came in today. I want to keep the stock 18s in tact. Can I purchase additional TPS from Nissan? Anyone know how much? Any other issues? Or, should I just switch off the TPS? How do I do that? Thanks in advance.

New TPS from Nissan is VERY expensive. No way to switch off the TPS. Your best bet is to find a set of used TPS in the Classified section.

 

I forget how much each sensor was. I think new they were something like $250 to $290 for each sensor.

I don't know of any way to just turn off the TPM system.

 

Yeah I just called Nissan. They are $290 each. They must be smoking something. I guess I have to break down the OEMs to retrieve the sensors for the new rims

 

I had the Nissan dealer take off my stock wheels/tires, pull the sensors from them, put them in my new wheels/tires, and mount and balance them......cost under $70 for the whole thing ($17 per wheel). Not bad. Might be worth checking out at your dealer.

 

I have a set of TPS for sale if you are interested. $225.00 shipped to your door. Pm me if you are interested.

 

What happens if you dont swap these into your new wheels? Is there some type of warning that goes off all the time because it thinks you have 4 flats?

 

No alarm or warning comes on. The tire pressure sensor option on your guage doesn't show up.

 

Eh....no. There is a warning light that will come on after so many continuous miles of driving. Restarting the car resets the warning light.

 

Thats what I was afraid of. I guess I'll be swapping the sensors into my new wheels.

 

Are these sensors helpful to anyone?
Seems like it is more expensive/annoying than anything else.
How does this compare to just haveing a tire pressure qauge in your glove compartment, and checking the tires at fillups?

Sorry for the thread crap. Wasn't sure if this is worthy of its own thread.

 

It actually is a very nice system. These tires are low profile enough that it would be relatively easy to not notice when one of them is dangerously low. I picked up a nail in one of my tires, and the TPS system alerted me to the slowly decreasing pressure, allowing me enough time to get to a shop. Not having to change the tire on my sports car on the side of the freeway even once is worth it to me.

 

Well you are probably right, but they came on the car. The wheels and rubber are finally mounted. Pics to follow. As far as the TPS is concerned, I had a problem with them. It seems that even though my wheels use a straight valve stem, the recess in the wheel for the stem is too deep and not wide enough to get a tool in there to tighten them. Unless there is a special tool or key for this I guess I have to leave them out. The guy who mounted the tires took one off the OEM rim and showed me why they wouldn't fit. On the briter side of thigs -THE WHEELS LOOK HOT!

 

You should investigate the HRE wrap bands. They will allow you to mount the sensors via a metal strap around the middle of the wheel. They look quite secure, and most people that use them have had no problems with them.

 

if you don't wanna put the TPS back in my Nissan service advisor (who was a really cool guy) said there's a fuse you can pull so just that TPS warning light will stay off.

 

Based on 2 consecutive road trips this past weekend, I can confirm that the tire pressure warning light comes on after approx 20 miles or 20 minutes. I dunno if it's distance or time because I was on a highway doing 60mph.

As long as you know that it's just a light and not really an issue, it's not a big deal. And when you turn off the car, the light resets like he said.

 

It's interesting how much variation there seems to be in this system in both the time to activate the error light, and the PSI at which the warning kicks in.

We did a group drive the other day and my car ran for probably 3 hours and well over 100 miles non-stop and my TPS light never came on.

 

Hmm, that's really interesting. For my car, it's definitely the 20mile/20min range. Ever time I hit that magic number, it's comes on.

Does it have anything to do with the weather conditions or temp? I was driving in rain the whole weekend in 50 degree weather.

 

you will also have to have the TPS reset every time you switch wheels...

the TPS will work in ANY rim... but in two piece wheels that normally use L-Shaped Valve Stems the stem will stick straight up in the middle of the wheel...

Some wheels use a short valve stem that is hidden behind the spokes... ya know... hidden valve stem = luxury... so it is kinda the same... putting air into them would be harder though this way...

i personally dont recomend doing the above or straps...

run without TPS and you dnot get lights until you drive for 45 mins... then you can turn off the car and turn back on and they go away... no alarms...

 

so there is a fuse that controls only the warning light, huh? has anybody pulled this allusive fuse to see if that will take care of that light?
