alright kiddies, we're lucky to have a huge thread dedicated to aftermarket wheels sizes offsets tire sizes and so forth. there is some information in said thread that discusses the TPM sensors, as some have adapted them to their new wheels, some didn't even know it was a problem, while the majority of the community seems to be frowning but dealing with the idea of relocating them to spare or wheel barrow wheel. well here's the, i'll just call them rumors, that i've come across so far.

• tpm sensors only work on 1 piece wheels
• thick walls are needed to make room for the tpms box
• volk wheels do/do not work w/ tpms
• the list goes on its early and i'm lazy

upon ordering my volk gt-s the other day me and my salesmen tried to figure out the truth via mackin. they said tpms will only adapt to 1 piece wheels and multi-piece is out of the question. however i know one member on here with gt-c(i think) reports that he has them working w/o a problem and i believe never knew there to be a problem in the adaptation.

so basically, post what wheels you have, single or multi-piece, and your experiences with the TPMS and how you or your installer adapted them to your aftermarket setup.

i think this information made readily available to the community will relax the fears of many owners on the fence between stockies and aftermarket wheels. thanks.

also anyone who has posted a setup in the aftermarket wheel thread I added a field "Compatible with TPS?" in the template somewhat recently, please add yes/no if you have posted your setup there

Possibly disable TPMS

tpm sensors only work on 1 piece wheels - not true. my bbs wheels are two piece and the sensors work fine.


thick walls are needed to make room for the tpms box - somewhat. the wheel has to have a seat or depression near the inside of the wheel lip to accomidate the size of the transmitter. your valve stem angle also has to accomidate the design of the box. for example, the RO_JA's R2-5 valve stem sits in the middle of the wheel and the stem itself is an aggressive 90 deg angle out to the lip. the way the tpms transmitter is shaped wont allow it to sit inside the middle of the wheel and the length of the valve stem wont allow it to work. the sensors are two piece, the transmitter then the valve stem. the sensor stem has to come directly out from the box, it cant make crazy angles. because of that many wheels with a 90 deg valve stem cant accomidate the sensors.

my wheels will have the same aggressive 90degree bend ase seen here, but have extended valve stem options...thing that would work?

G35TOIS350

prob not. see, you cant use the stem that comes with the wheel, you have to use the one that screwes into the transmitter box. so if you put the transmitter in that wheel and used the required stem you would have to stick your arm thru the spoke and air it up in there (thats if the valve stem didnt hit the rotor and caliper). it would never work. the wheel has to be desgined with a valve stem system that is close to the wheel lip.

oh well wheelbarrow wheel for me, until someone confirms tpms off mod.

G35TOIS350

sorry man. i see this every day cause i work in the tire/wheel industry. and when the laws change to make tpms required on every vehicle within the next couple of years it will be an aftermarket wheel nightmare

G35TOIS350

these are the exact Lexus sensors but it will give you an idea of what im talking about.

your wheel takes the chrome 90 deg valve stem you see in the first pic. just a universal 90 deg stem, not tpms specific.

see how they screw together and cant make any funny angles? the sensor has to sit in notch so it dosent get damged during mounting/dismounting, and the stem has to come directly out. so there's no way to make it longer or angled and still work. sucks cause i wanted the RO-JA wheels.

TPMS modules can be transfered to ANY new wheels.

You need to find a reputable wheel/tire shop to have it done. There will be some modifications needed depending on the new valve stem type of your new wheels.

This is what I heard from the shop, but believe it or not, these modifications can be a combination of things like:

1. Drilling holes to mout your existing modules. (ending up with 2 valve stems, but only 1 is visiable)
2. Modification on the TPMS so it will take the valve stem on the new wheel.
3. Modification on the TPMS and hide it internally.

We drive without TMPS in last 2000 years. I guess the TPMS are the bells&whistles that the automovtive manufactures wants more bucks from us.

hey trust me its not something i'm really worried about. its not like i'm running on 25 tires or anything. i'll be on 35f 30r, not overly concerned.

its just that it comes with the car so you'd like it to work more than just not use it at all, its like a waste ya know. thanks for those 3 points, i'd be willing to make perm mods on the wheels/sensors if it worked (afterall i plan on riding them till they fall off :-D)

a cheaper ghetto way of doing this is get a go kart tire/wheel throw all the TPS in the go kart tire inflate to 30 psi and put it in your trunk neatly away

TPS stuff was a result of the Ford/Firestone fiasco

This is the sensor from the dealer for the IS350.
