ok here is the deal.... my car has just about all the suspension upgrades for a thirdgen.... all of my parts are non adjustable except umi camber plates and its stock height..... i have brand new kuhmo ast tires in the rear, sumitumo htr+ tire on the front driver side and a tempest doral tire on the front passenger, all of these are 245/50 16 tires... i notice that the kuhmos are just a tad taller tire the than fronts... the sumitimo front tire is worn on the outer edge and a little bit on the inner edge and has ok tread in the center, the doral tire has inner wear and good tread everywhere else.... so basically i have 3 different makes of tires on my car... my car wonders from left to right...... my cars handling feels like a wet noodle and just doesnt seem to hug the curves like it use to..... could my tires be the problem and... i just got an alignment with the new rear tires and it still wonders from left to right and steering and handling has been reduced quite a bit....... what could it be... this might be a dumb question but its really annoying me....

 

it could be other things, but having different tires on each side of the car in the front is not helping.
