Hi all, As some of you know, I upgraded to new wheels a few months ago. I had my TPMS from the stock wheels transferred to the new wheels without a hitch. I just had my dealer put on new sensors on my stock wheels which I plan to use for Winter. When I picked up my stock wheels, I was told by one of the techs that they need to reprogram the new sensors into my car. Now, I heard about this before in this chatboard. But, what I wasn't expecting to hear from the tech was that as far as he knows, the prius can only recognize one set of sensors. So, he said that whenever I switch wheels on my 2006 prius...I'd have to go back to the dealer to have them reprogram the computer again! For those who have experience in having 2 sets of wheels for their prius, please tell me this isn't so! Also, is there a way for us owners to program the sensors ourselves? Thanks. Vince.
