I.m Getting dedicated winter rims. I assume I have to use OEM sensors for my snow tires?
After programming them the first time do i need to reprogram each time I swap summers/winters rims/tires .

no just use setting 2 for the snows, switch between 1 and 2 for summer/winter

So no reprogramming when u have to switch summer/snows .

see owners manual p299-300

thankyou. I assume all sensors are OEM no after market

I bought my second set off ebay some years ago. They usually have an application chart to make sure that they are suitable for the vehicle

i have a 2011 i don't see those buttons
