After swapping out my rims and tires to put my snow tires on about 4 months ago, I only had the TPMS light come on twice. I was under the impression that it would be on all the time, since I didn't swap out the sensors. I was beginning to wonder if it even worked at all until the light finally came on.

Both times were during long road trips though. After about 50 or 60 miles without stopping and turning off the car, the light came on. During everyday commutes of about 25-30 miles, the light never came on.

 

You can retro-fit your TPS to your aftermarket rims. There are several ways depending on the rim contruction. Some rims allow simple use of the TPS as a valve stem as in the factory set-up. It is my understanding that the rims with the fat lips do not allow using the TPS as a valve stem as in the factory rim application. These fat lip rims require using a normal valve stem and relocating the TPS either by banding to the inner circumference of the rim or there is a new bracket that has been developed that uses the threaded valve stem & hole of the rim to attach securely to the rim and then the TPS bolts to the bracket. James at CreativeAutoWorks informed me of this when I was purchasing my new rims. There is a link in another thread here in G35Driver that goes to another forum that shows pics. I'll see if I can find it. I really feel that using the TPS is a must with aftermarket rims because I want to make sure I am alerted to a low pressure situation so I won't risk bending a rim.

 

F1 will be transferring the TPS's for me.

 

please let us know what you find. thanks for the info!

 

I had mine transfered from my 19" stock wheels to my 17" Enkei wheels with Blizzaks last fall with no problem. Discount Tire did it for no charge when they mounted the new wheels and tires. Tech told me when looking for the winter wheels that they need to have a front mounted stem to allow the TPS be mounted. Of course the Infiniti dealer told me it can't be done and I need to buy 17" factory wheels (at $350. each!). Only problem is I need to switch the TPS each season when I change the wheels. Dealer wants $110. for each TPS so I'll keep switching them.

 

I switched wheels to aftermarket wheels about 20,000 miles ago on my '04 G35x. The new wheels would not accomodate the TPS so we decided to leave them off. The shape of the rim does not work with the TPS. Some wheels will accomodate them.

When I drive, the warning light will come on after about 50 miles of highway driving almost every time I drive, but there is no audible warning. If I stop the car, turn the key off and then restart, the light is off. It is annoying but I've gotten used to it. I live in Colorado and the high altitude and temperature swings cause these things to go off all the time normally, especially in winter. Wish there was some way to turn it off.

 

I'm transferring my pressure monitors to my Maya's but they won't fit in the valve stems, so I'm going to strap and silicone the sensor inside the wheels.

Here are some how-to links.

Did you get your Maya's installed with TPS yet? I haven't done this yet but I'm not sure if silicone is a good idea? You probably want to have something hold the bands in place and not slip inside your wheels but with the rpm and change in temps inside the wheels, the silicone will come loose over time. It may end up breaking loose and bounce around in the tire. I suggest putting heavy duty double sided foam tape between the TPS and wheel while banding it down. It will reduce slip or movement of the band if any and won't come loose like silicone since it's banded down. Make sure you put locktite glue on the banding screw to prevent it from backing out. If you haven't done so, take pics of the process too.

 

I haven't installed the TPS yet. I'll take some pics when I do it. Thanks for the tip on silicone.
