What do i have to do???

 

Hey Mario,
There are special tire dismounting instructions for wheels with tire pressure sensors. That's very important because improper dismounting could damage the sensor.

That aside, once you have the tire off the wheel, the "nut-collar" you see on your valve stem will actually unscrew, allowing the sensor (which the stem is integrated into) to slip back off the wheel....

Here's a pic from the service manual....

 

hey Kelly.... Dawm.. so I have to take the tires off??

 

well...

take it to a tire shop... this isnt a 14" wheel with 70 profile tires...

near impossible to do by hand...

 

very carefully.

I had a tire-changer guy break one in NYC

and here in Sd a tirerack guy broke one

they cost $150 so be careful.

unless you are sure....have a pro assume the liability.


yes...the tire must come off! but carefully, thats when they can break the easiest!

 

So ... do you have to use the stock valve stem with the sensor? Is the sensor able to be separated from the valve stem? I.e., my new SSR's have very cool valve stems -- do I have to lose those to get my TPMS working again?

Heck -- does anyone know if the sensor will even work with my new wheels (SSR-Comp H)?

 

the TPS is the whole valve stem assembly... if the SSR Comp H use at regular valve stem and not one of those funky L shaped stems you can use it...

 

why would you want to do this?

 

Not many service manuals for cars tell you how to take the tires off the wheels, but the Z's does. There is a specific way the bead bar is supposed to be placed so that it doesn't rip the sensor off the valve stem. If you ever take your car (if you have TPS) to an aftermarket tire place, MAKE SURE you tell them about the sensor or they will likely destroy at least one of them.

Someone out there figured out how to make a set of wrap-bands for aftermarket wheels that effectively strap the sensor to the hub. This way, the stock stems can be used, and the sensor stays securely in place. Run a search and you'll probably find it.

Why would you want to do this? Well, if you had a sensor go dead you would. They are battery powered believe it or not. When the batts die, you gotta take the tires off to change out the entire sensor. You can't replace just the battery because it's molded into the sensor housing. Performance Nissan sells the sensors for something like $225 each. Can you say ouch? It's reported that depending on use, the sensor battery should last anywhere from 5-7 years.

 

cool... thanks for the info
