ok i have an fx45 with the tech package... now i need to get snow tires and rims.. my question is this.. if i get another set of rims do i need to have the pressure sensors in the rims? or will it cause problems with the computer? has anyone done this at all ? i just dont feel like having to buy 4 sensors just to put in the snow rims and tires to use for 5 months of the yr.
