255/40/18 - has anyone with a sedan run this size in the rear?
so, i picked up a set of OE E9x M3 ContiSportContacts for cheap recently - they are basically take-offs, production date is late 2011.
i am currently running OE-sized general gmax AS-03's which came with my 135Ms - they are fine for commuting but other than that, i do not like them.
so, i'm sitting here with this set of contis in my garage, wondering if i can get away with the 0.9" larger in diameter 255/40/18 tire in the rear of my sedan. anyone done it before?
can i re-calibrate my speedometer with BMWScan?
