Hi, I only ask this because I want to get a winter setup from tirerack but I dont want to spend the extra $400 for the TPMS. I dont think its important since ive been driving for 8 years without it and ive never had a problem noticing if my tire was going low.

Would anything go wrong with the car? Like the ECU cutting power because it thinks theres no tire pressure or something like that? Or would it affect the AWD system? Forgive me but I really dont know how this stuff works and all ties together. Thanks.

 

the only bad thing is you need to pay attention to your tire pressure the old fashion way. And that the stupid low tire pressure light stays light on the dash. It's yellow so it sorta interferes with the nice color scheme but it's not too bad.

 

I have an X and aftermarket wheels without TPMS... only thing you'll see is the TPMS warning light on all the time, but other than that, you should be good.

Oh, and you have to keep checking your tire pressure yourself, but you're probably doing that now anyway so...

 

so is there a way to bypass the fact that the light is on on the dash by getting another set of sensors to put into the aftermarket rims so wouldnt have to take apart the stock ones and then again taking off the aftermarkets to put the stocks back on?"?

 

There's talk of disabling the TPMS warning, pulling fuses, etc. I think most people have decided to just live with it.

 

well that wouldnt be me in that case. when spending 40k for a car and then whenever someone gets in the car "HEY MAN YOU GOT A WARNING LIGHT ON, WHATS WRONG" BLA BLA BLA

 

Your call... then go spend $400 on the sensors and have the tire shop mount them, and have the dealership re-sync them with the car.

Keep in mind that there are some wheels where you just can't put sensors on, so you probably should do your homework. Someone mentioned something about straps and what-not, but I haven't seen any links.

 

Not at all.

It will like not having the TPMS. Like older cars don't have it. All you should do is to check your tire regularly. This would be a manual process.

 

IANAL, but I believe that the way NHTSA acts has blanket language that basically says you can't allow the ability to defeat safety feature required bu NHTSA unless the act specifically says so. For example, after the airbag fiasco, I think congress actually had to pass legislation allowing car manufacturers to disable the airbags due to kids being killed. So don't blame the car company..

To use your same argument, if you're spending 40k on a car, you can afford the $400 for new sensors.

 

Thanks for the info guys!

 

The rules regarding TPMS inclusion in all new vehicles is not retroactive... that's just like every vehicle that came without an airbag, you can't MAKE someone go retrofit one, they're grandfathered in as an exception. If your car was built before the requirement went into effect (whether it's TPMS or electronic stability), you can do whatever you want with your car.

Correct... and most people can afford to have 6 sensors on every wheel. That's not the point... it's that some wheels are constructed so that you just can't put a sensor inside.

If anybody told me that they could fit the OEM sensors into my 20s, I'd do it tomorrow. The guys that I got the wheels from, that installed everything and even took off one of the sensors to try, said that it wasn't physically possible.

If that changes tomorrow whether because there's another aftermarket solution, different sensors, straps, whatever, then that's another story... but it's not always about being cheap. If the sensors were free I still couldn't use them today.

 

Yeah, but in our case, we're talking about a vehicle that came with it, so no grandfathering

Well, that's your fault. Geez, aftermarket rims, what will they think of next .

 

This is a stupid question, but how do you even find the pressure reading on the screen? I swear I looked everywhere.

 

I ran straps on my wheels but the sensors kept coming loose inside. Now I run without sensors. It is possible to mount the sensors on 20's and 22's, but if I were to get a flat, I would have to say goodbye sensor.(due to clearance from the barrel of the wheel to the floor, the sensor would be demolished)

 

are all tps the same from 05 and on up? If so I may have some for sale.
