My 2001 mercedes clk430, codes po500 and po720 come up after changing to new tire size. Original size (f-225-45/17, r-245-40/17). And new wheel and tire size im putting on (f-245-35/18, r-285-35/18). My question Iis there anything I can do (recalibrate) to the vehicle so I can run these new wheels and tires. Or do I have to run the same (original) tires all the time. In other words I can't change wheels and tires on this vehicle.
