max size in back is 255/35/19(what you already have)

increase the front size from 225/40/19 to 245/35/19 to reduce understeer. here is a person that has done it (from our sister forum)

don't go cheap on tires

245/35/19 is 10mm oversize on 8" =slight bulge. It is no different than the oem rear, which is 255/35/19 on 8.5(10mm oversize=slight bulge). 255 really fits best on 9".
