i bought new 20 inch rims for my 04 coupe they require 42

can i install my old tire pressure sensors on these rims, will they work right seeing that the psi copunt is higher

can i make them default to 42 psi rather then the 35 on my stocks?

 

iS THIS NORMALLLLLL ENOUGH??

 

haha
please help

 

i think the sensor goes off when the psi drops below 32'ish, so it shouldn't matter if u have anything above?

 

not true. the pressure sensor doesnt actually measure tire pressure it works based on ride height. Ive heard stories of lowered coupes with this problem including mine.

You'll be jsut fine w/o the sensor, just keep an eye on the pressures youself. Check the tire pressure in the morning before a drive about once a week.

 

w/out the sensors you will have to get used to the dash light
that is triggered by the sensors.... my guess would be to get them calibrated at the dealer once you get the new rims.......

call & check with them first....

 

The sensors are for the PSI and NOT for the height of the car. Second, 42 psi is too high to have on any tire on that fits the G. You will find the ride too stiff, harsh and considerable road noise.

The recommended PSI varies from 32 psi to 36 psi, depending on your driving habits and your comfort expectations. If you put the sensors on they are programed to triger the warning light if the PSI drops below 28psi.

If you decide NOT to put the sensors on the wheels, the waring light will go on the dash 45 minutes after highway driving. During regular city driving the light will not go on.

 

^yep.. careful when removing the sensor or let the guy mounting your tires know you have sensors or else he can mess them up pretty easily.

 

Can't you just by a resistor of the same voltage and wire it in to the circuit before the sensors...basically telling the computer that the sensors are there even though they aren't? People have been doing that for o2 sims for some time now.

 

are u sure on this? how does it measure pressure in the tire itself? the wheel/tire is rotating and the sensors arent in the wheels. if your pressure drops below a certain point ir ride height in that area will be affected thus setting off the low tire pressure sensor. i could be completely wrong but this has always been my understanding

 

You are completely wrong like you said. The sensors are in the wheels and that's all they measure...PSI. The height of the car has nothing to do with them.

 

^^ Like Chico said. Here is a pic of a sensor that is mounted in the wheel.

 

Hmmm that's interesting. Made in the UK?

 

The tire pressure sensors are RFID pressure sensors...the signal is picked up by a reciever/ broadcast antenna in the car..mine go off driving @20mph ~5 minutes after I take off if my tires are low(<25psi). As I am normally driving an autoX road to work I keep my pressure @45psi and endure the harsh ride and road noise in favour of a bit stiffer tire that seems to handle better.

 

Chico is spot on with his info. Pay attention to it.
As for whether the pressure sensors will fit in your new wheels? It varies from wheel to wheel. Some will take them, some won't. Check it for yourself before you agree to buy the wheels, don't just take the salesman's word for it. A few general rules of thumb I discovered when I was wheel shopping. One piece wheels usually do not accept the sensors. Two piece wheels sometimes do. Three piece wheels usually do. Of course there are always exceptions so verify info for yourself.
I ended up buying wheels that accept the sensors and I'm glad I put them in. I had a low pressure situation recently and the sensors alerted me to it before it became a big problem.
