if you reduce the size of the tire in the back to match the front, the *tendancy* is to create more oversteer or less understeer. If you tried to match the rear tire size with the front, that is the wrong way to go, as the tire is too large for the rim size.
Ideally running the same size tires and wheels front and rear would be best
MOST cases of understeer occur because of entry speeds being too high or the driver upsetting the balance of the car.
Minor adjustments in tire pressures can dial out some of the understeer (higher back pressure to give less rear grip) but you really need to mark your tires and read the rollover *or* take temperature readings to REALLY know what you and the tires are doing.
