I have different set of tires for my g coupe

General tire 225-40-18 ( going to replace new falken soon)
Falken 245-45-18 ( new tire )

my front tires made really loud noise and i don't have money to replace new tire yet but until then can i do alignment like that or i have to get the correct tires? my rear tire wore out uneven

 

if your front tires are loud it's probably because they're chopped on the inside edge, alignment won't fix it

mine are the same, but i'm waiting until they wear down more before i get new ones
