Default TPMS Sensors - Inside or Outside of Wheel?

I just had some TPMS sensors installed on my aftermarket wheels. The shop put them on the inside of the wheels facing into the vehicle. Is this correct? Should they have been placed to the outside (same side as the tire pressure valve) so that you can easily access them with a TPMS tool? Or does it really not matter? The way that mine are placed you cant get a TPMS tool hooked up to the wheel while on the ground.

I think that the shop messed up but not 100% sure and need some advice.

I can take some pics tonight. All I am trying to say is that the valve stem that is used to put tire on your air is on the outside edge of your wheel. The TPMS sensor was installed on the other side of the wheel (i.e. it faces towards the include of the wheel well). The shop drilled holes into my wheel to install the mounts.

Wont be able to make the meet. Had already committed to other plans prior to knowing about the meet.

from what i know about TPMS is that the valve stem sticks through your wheels lip, and the actual sensor is on the inside where the tire will cover. And a "nut" tightens down on the valve stem side to hold the sensor in place until tire is installed and air is in it..

I may be overanalyzing this...

that is correct. When you say the wheels lip, that means that the valve stem of the TPMS sticks out away from the car (i..e its on the same "lip" side as the valve stem for adding air to the tire). My valve stem is on the opposite side of the wheel.

Pictures would definitely be helpful but unfortunately, I am not work right now and just trying to explain it to the best of my ability. Probably makes a lot more sense in my head then when I type it out.

Since you apparently have a valve stem that is easily accessible I don't understand why you would ever need to use a tool on the TPMS sensor. Is it possible the wheels would not accommodate the TPMS and the shop had to install them a different way?

Haha.. Yes there are 2 holes. One hole is for the OEM stem valve to fill air into the tire. And then there is anothe hole that brings out the stem valve for the TPMS sensor. The stem valve for the TPMS sensor is on the inside of the while (the side that the brakes are on).

The tool would be necessary to read the 8-digit code that is associated with each of the TPMS sensors. My tire pressure light is on everytime I start the car since the TPMS sensors are not calibrated with the ECU.

I would tell the shop to buy me new wheels if they drilled a hole for the TPMS. Your TPMS goes in the hole (away from the car ) and also is used to fill the tires.

Some wheels comes with the 2 holes. I had a set of aftermarket like that.
The regular outer hole will not accept the sensor but the inner one did.

Here are 2 pics of my wheels.

On the far shot, the stem valve is on the bottom right corner and this was the one that they kept on the wheel to put in air. I circled it in red.

On the close up shot, you can see the valve stem is sticking out the back side of the tire. It is circled in red also.

Doesnt look correct to me. =(

I guess I havent had too many wheels.... BUT, OP said that the SHOP made the 2nd hole. I know someone on here has had PIAA rims like this.

Agreed. Doesnt look correct. I would say if it works, use it, but you said the TPMS light is on in your car all the time? Tell the shop to get you new TPMS, or wheels.

Those wheels were brand new when they were put on the car for trade show purposes (5000 miles back). I bought the car with them already on.

Cpatel, the early PIAA Super Rozza wheels could not accommodate the TPMS in the standard air valve position and didn’t have any alternative brackets for them. It looks like the tire shop found an innovative solution. As you know Nissans need a special tool to calibrate the TPMS units to the car’s ECU. Shouldn’t be too hard for the Nissan tech to reach around with the reader to calibrate.

Thanks for the info. When I went to dealer they were unable to access the stem valves for the TPMS sensors without a whole lot of additional work that I didnt want to pay for. Figured that their may be a cheaper alternative available that individuals on here have found to do the programming.

On another note, I read that people disconnected their battery after programming the TPMS and after hooking back up the ECU was reading the TPMS sensors properly (they had an intermediate time when the TPMS sensors stopped reading). I tried this by unhooking the negative lead only. Should I have unhooked the positive and negative leads? Dont think that this will solve the problem but figured its worth a shot.

Cpatel, some larger tire shops have bought small portable Nissan type readers. They may be able to do the job for you without making such a big deal out of it like the dealer seems to be doing. Unfortunately only Nissan’s need this external tool to calibrate.

You’ll have to phone around to find one. Have your girlfriend take the car in for the job; I never get charged for things like this.
