A guy is selling '06 M6 17" OEM alloys with good snow tires mounted. I do have the 04 6 wagon, but I actually want these wheels/tires for our '15 Mazda 5 Sport (16" alloys) for winter use. I understand that they'll fit ok and work because the 17"s take a lower profile tire. I just want to verify they'll work fine, and that I'll have to get the shop to install sensors if I don't want a light. Does this sound right? I can save a shitload of $$$ this way, but want to make sure it's smart/safe ?
