5.5 gen lug nut size
 

I have a pair of xxr 530 wheels and i had some gorilla tuner lug nuts that i used for my eclipse they were m12.1.5 the tip goes on but when you try to screw it in it gets tight at beginning and wont budge at all so guessing i need a bigger size what size do these cars take?

Not the right thread pitch.

12x1.25 is what you need.
