hey guys, i had my stock tires replaced about 4 months ago, and i did my alignment a day after. After the alignment my car seemed fine for about a week and its started to turn back to the right a bit more, it didnt turn that much so i didnt mind it.

Recently it feels like my cars handling is all that great, on the freeway the steering wheels seems loose or something and it seems to swirl back and forth. Im not sure what the problem is, should i do another alignment? i just check the tire pressure and it seems fine. could it be that my tires are unbalance? if you guys can help me out. thanks

my car is lowered on Hotchkis for about 30,000 miles with stock struts
progress rear sways on max setting.
