165/45R15 is miles from an OE size of tire for any smart.  What year and model do you own?

The best solution for compromise between economy and handling is 175/55-15 front and 195/50-15 rear on wider wheels.

 

Your ESP and ABS are going nuts because the circumference difference between front and rear is too large.  The car "thinks" it's always skidding.

The offset of the rear wheel is the reason they rub when placed on the front.  There are steel and alloy wheel sets that would permit 175/55R15 to 195/40R16 to be run on the fronts.  Evolution.co.uk, lists all the available OE wheels for the 450 smart.  I run Roadster steel front wheels on my 450 with 175/55R15 all around.
