Hi all,
Just swapped my alloys over for a set of steel rims and tyres for the winter. I'd purchased the steels from another forum member in preparation back in the summer (no problem - but obviously had no history of their former life - still no problem). However - whilst having the tyres fitted - on (inside the tyre effectively) two of the four rims was a jubilee band holding a transmitter device about the size about 3 - 4 inches long and an inch high. I've had them removed and wondered if anyone knows what they would be for and if they were for a particular spec car. My thoughts are they are probably tyre pressure sensors of some sort and I can only think that 'plod' cars might have used them. Anyway I have 2 spare if anyone can find a use for them (I obviously have no idea what they would transmit to or if they work) :-?
By the way - I buffed up the hub caps, removed the centre badges to paint red behind them, polished the badges and re-secured and d'you know what - it looks the muts. I'll get some pics when a) the weather is warm enough to let me wash the rest of the car - but the wheels look fantastic.. :y
Cheers
Ian.

Have you got any pics of the bands that came from inside the tyres/wheels, i'm very curious as to what they might be for :o
-
Tyre Pressure sensors are a fair bet.
Potentially a very accurate speed measuring device?
Very intriguing!
-
Flux capacitors, fo' sure.
That's two point forty-two gigawatts of power you've just lost. :P

I cant believe the advice some people on here give.
Everyone knows Flux Capacitors were only fitted to DeLoreans.
So Stupid! :(

yes - tyre pressure transmitters.
now a legal requirement in the USA and available in the aftermarket here, as well as on new cars.

..thought they might be .. I'll get some pics up later in the week - they're still rattling around in the boot at the mo. I'm intrigued why they'd be on a set of steel rims that are most likely off a lower spec model - 205/65/15's - is the tyre size I've just fitted to them to replace what was on there. Does anyone know if 'plod' cars had pressure sensors fitted ?

Hi mrjimbo - yes these were the rims you gave me - I'll keep you posted. You don't happen to have a redundant tyre pressure display lying around in your car do you ?? ;D

Nice idea this IMO. http://www.google.co.uk/imgres?imgurl=http://www.tyrepress.com/thumbnail.php%3Ffile%3DContinental_indexprint_FillingAssistant_Page_2_web_179879660.jpg%26size%3Darticle_medium&imgrefurl=http://www.tyrepress.com/News/1/tpms_rfid/20338.html&usg=__pE7bcZokwtGsZ0rX9SHw1y6a_cY=&h=225&w=300&sz=14&hl=en&start=157&zoom=1&um=1&itbs=1&tbnid=YyFT0vuNZ_atiM:&tbnh=87&tbnw=116&prev=/images%3Fq%3DTyre%2Bpressure%2Bsensors%26start%3D140%26um%3D1%26hl%3Den%26sa%3DN%26ndsp%3D20%26tbs%3Disch:1%26prmd%3Di
However it does seem daft to have the sensor in the tyre :-?
-
Ok - here you go. I have heard some theories about how these work - but I'd still expect 4 to be fitted and there to be a receiver in the vehicle. Anyway according to their website - they no longer do these for 'automotive' use. I'd still love to know if the plod fitted them.

Here are the pictures:

One is obviously a transmitter - but not sure what the other one does - but I believe that these work by comparing relational speed of the wheels to each other rather than actual pressure. So a drop in pressure affects it's speed with respect to the others - I think :-?. But you still need to send the information to a visible receiver somewhere don't you.
Why only 2 ? - I have no idea if these were on the same axle or front / rear - Mrjimbob do you know any history of these wheels whilst in your posession or prior to that ??.
Next time you're having tyres fitted - it's impossible for the fitter not to know these are on the rim because it's a :-X to get the tyre over the top of them to get it off.
There you go - a mystery :y
Cheers

I'm guessing not just a barsteward to get the tire over the rim, but also a complete git to balance the wheel too.

..not 'alf - there were some big b***er weights on the rim - but if you look at the steel band there are some counter weights threaded on the banding that were on the opposite side of the rim whilst they were fitted..
-
Lol at the freebie plastic vernier from one of the elecronics magazines a few years ago.
-
I seem to remember that the 2 rear tyres had more balance weights than the front and it did have a slight balance problem on the rear wheels that the tyre fitters could never seem to cure i eventually put it down to the propshaft.
I can see why they couldn't get it right ;D

Looks like it should be strapped round the neck of a bear as a tracker!

just to clarify
they are indeed pressure sensors
these were the first generation supplied by smartire based in newbury
and yes there is a counterbalance fitted opposite the sensor
these were a requirement when fitting run flat tyres such as Goodyear emt
so yes would have been fitted to several police cars
just for info the second generation sensors were mounted to the base of the valve and the third generation are now biult into the vehicle and uses the abs sensors to detect differences in rolling circumferences
hth :y
just noticed your photos this sensor was fitted to the nearside front ID3 and yes there would have been a display inside the vehicle these sensors also measured temperator as well as pressure

Interesting that they were 'requirement' when fitted to Run Flat Tyres.
Kind of defeats the object. ;D
-
the reason behind the requrment of the sensors was Goodyear EMT tyre could be flat without a notice to handling or visual signs but a flat tyre would wear the shoulders of the tyre very quick

Would that be because they felt flat even when inflated? ;D

Eee that's proper cunning, that. 8-)

in the USA it was a kneejerk reaction to a number of SUV pressure-loss crashes
