Im deciding on some wheels for my 335 and have a question. If you change the wheels will the pressure sensor automatically adjust to the new wheels or is there something that you have to do in order for it to read the pressure of the new tires?

You have to reset it whenever you change tires or even inflation pressure. Check your manual or our FAQ sticky on how to reset it, it's pretty easy. I assume you plan to move the sensors if you have TPMS or purchase new ones.

I just ordered a new set of TPM's for my snow tires/wheels. Now the switch from snow to summer is simple.

Yea, If You Have Ftm Then All You Have To Do Is Reset It Once The New Wheels Are On. If You Have Tpm Then You Have To Buy Or Transfer New Sensors. Not All After Market Wheels Will Accept The Sensors...... To Find Out, Call The Maker Of The New Wheels. If They Can't Tell You, Pass And Buy Something Else.....

Im thinking to go with Style 269 bmw wheels.

I Would Suggest Calling Your Dealer's Parts Department And Find Out If They Will Accept The Sensors..... Unless You Don't Have Them.....
