Are we able to recalibrate our speedometers. Mine is about 5mph off. And can we shut off our TPMS? Might be a dumb question, but I remember 10 yrs ago I was able to in my old 745.

Thanks

Not to thread jack but..
I wanna know about the TPMS also & can I run 2 sets of TPMS instead of switching them back & forth between wheels? I searched but no answer..

Not sure about this one. But I have experienced that mine is off as well, as much as +3-5mph at 70mph. I also noticed that the cluster gives different readings, i.e. if I set cruise control right on 70mph on a flat roadway, then reset the average speed, it will read average speed as 67mph or so, never 70mph despite no change in speed. My portable GPS unit confirms the speed as given by the average speed indicator.

I understand the LS can only store one set, unlike the GS which can store 2 sets and has a switch to allow you to select. Someone correct me if I am wrong please, because all of us with wheels want this one.

good question would be to know before mount the wheels

you can only have one set of TPMS programmed at any given time with our cars, and i don't think there's a way to disable it. what you can do is have your tire shop make a "TPMS bomb", which is basically a pressurized container with the sensors tossed inside. i know a few guys who have aftermarket wheels who have done this

One additional solution - particularly useful for those in wintry conditions 2 sets of tires/wheels (snow and "regular") is if you have a DISCOUNT TIRE store near you. They are simply wonderful and many/most times, if you ask them nicely or call and request a good time to come in - they will perform the TPMS "reset" at probably no charge. They did mine, adjusted my air pressure on my Continentals for me, offered me a cold bottle or water - and then THANKED ME for coming in - for free. I feel sure CJIITY is gona rain in on this subject soon.

Good Luck ....... Working something out with a dealer is a CHEAP GOOD ALTERNATIVE that results in zero problems.

By the way ...... There are GOOD LOW COST TPMS Sensor alternatives available on eBAY. Please don't get socked into $50 - $75 EACH costs for TPMS sensors.

Good Luck to all,

If you have two sets of wheels, you can use your OEM sensors for one set and have the tire place scan the sensors and tell you what the sensor IDs are.. Write them down. Then call the friendly folks at Orange TPMS http://www.orangetpmsusa.com and order a set of their oe style sensors that can be pre-programmed with your OEM sensor IDs..that way, you can swap wheel sets back and forth and the car TPMS computer has no idea the wheels are different..pretty nice setup.

I picked up a set of OE 107 sensors from Ebay for about $80 shipped and the Orange TPMS sensors were about $130 a set IIRC...but, I was lazy and just ordered two sets of Ebay sensors..in hindsight, I should of went OEM and Orange so I don't have to run to the tire shop each time to reprogram them when i throw the OEM wheels on for long road trips..luckily Discount Tire does the programming for free..but still a hassle

Oh, you know it lol

yes, you should get an additional set of sensors instead (and i've heard a lot of cool things about the orange sensors); the tire bomb is something for people who have wheels that aren't TPMS compatible (like reverse lip wheels without the additional hole on the inner barrel)

So i was talking to a friend of mine & he says I can dump the 4 sensors in the spare tire & it'll do basically the same thing as the tire bomb..iono what'cha think??

kitchamp

Until the moment you need to use the spare tire...then its sounds like a bad idea.

CJITTY

Took the words right out of my mouth...with this car, do it right or not at all. That is just a turrble idea #barkley

For the OP:How do you know it is 5mph off? I hope you are not using the radar speed construction signs to tell you that information..those are not accurate at all.
