Interestingly Michelin has already discontinued the "Diamaris 4x4" rear tire in 19" size (285mm) and while you can still get the front in 19" (255mm) apparently it too will be discontinued. The replacement OE BMW tire is the "Latitude Diamaris" which at the moment isn't even being made in 19" (255mm) size. Apparently the only change between the two is the name, they are identical otherwise. Nice development, huh?
