For the first time I got a warning for a low tire.
I inflated the tire and ran the car for a few minutes but I'm still getting the warning.
In my other cars the warning went off after inflation.
Do I need to do a manual reset in the 1-series?

Pretty much. Annoying isnt it?

The warning should go away when you increase the pressure. Where your wheels ever moved from their original position? Did the reset fix the problem?

[Stohlen]

It should I agree, but for some reason it doesnt on alot of these. On mine, I have a slow leak in a tire, and every time it goes off and I refill the tire, I have to manually reset it. Every Time.

Yes, you now need to reset the tpms system. You need to set the new target pressure. You do while the car is running but STOPPED, use the iDrive or BC stalk to reset the tpms.

Ok I guess I will reset.
I have the original Dunlop RFTs on the original wheels.
The tire where I was getting the warning was at 25 psi. The other front tire was about 26 so I figure I would have gotten a warning there soon as well.
The sidewall says 51psi max.
That seems high to me. I inflated fronts to 32 and rears to 36. Does that make sense?

Use to recommended tire pressures on the drivers door sill jam. Your pressures sound fine, don 't run tire Max pressures. I usually run 2.3 and 2.8 bar for the high speed autobahns, you can run much less for added comfort. The reset you tpms while stopped, then you will need to drive a few hundredmeters for the system to reset and learn your new target pressures. :-)

Never use the sidewall as a reference. Thats just what the tire can take, not what it should be set at for your car. Because every car is different.

[ejm3]

Actually once I started driving it did reset by itself.
I couldn't imagine putting 51 PSI in those tires!

do you guys have to install a TPMS system when installing new tires and wheels ?
If you dont install these, how do you get rid of the warning lights @ the dashboard ?

Thanks for the inputs.

Yes, you need a 2nd set of TPMS for your extra snow tires/wheels.

There is an early and late TPMS freq too, so know which one your car has. I seem to recall that starting from Sept 2010 build dates(?) - BMW changed the TPMS freq.


Yes, you can also have either the entire TPMS coded out - so you don't get any low tire or lights/gong going off. OR... you can have the EU TPMS coded into your car. This will use the car's ABS sensors to detect a flat tire. This is something I think only the German coder's can do/offer. At least I have not heard of anyone doing it in the states. Smellthebeans - has had the EU tpms activated on his 128i.

46 psi seems way too high. What are the recommended pressures on your door sill? That can't be good for the life/performance of your tires...

[Twhill19]

thats on a hot day, in the cold i fill to like 34-38...i had them initially at 31 all around but i kept getting low tire pressure warnings every time i started the car...havent gotten one since...

[Twhill19]

guess its preference for comfort as well...

BMW full load max tire pressures for my 135i is 2.3 bar(33psi) front and 2.8 bar(41 psi) in the rear. I run those pressures bc I drive at high speeds (over 100 mph) on the Autobahn(s).

Help!
Just installed new Mich Super Sports on my 08 135 conv yesterday. I set all 4 tire pressure to 38psi. The TPM warning is up on the screen, telling me I need to reset. I went to the owners manual for resetting directions, but I can't get the screen to move off the warning. Pushing the menu button or the idrive knob do nothing. I have tried it with the car running or off and still the screen stays locked on the warning.

Even though this is for an e60... it should also be the same procedure for your car.

I got it reset. I held the menu button down when I first put the key in. The screen popped up and I guess I forced it into the menu screen. The rest went fine.

Thanks for the help!
