Afternoon all,

Looking for the thread size for the lug nuts on the Fiero. I have to get some lug nuts for these Scion wheels I just bought and know squat about what I need. Thanks in advance for your response.

I think it's 12x1.25.

Thank You Pswayne!

I believe it takes the standard GM M12x1.5. I'd double check in a manual before buying any.

They are, in fact, M12x1.5.

12 X 1.50 is the correct size. I picked up one of those cheap 4 packs they sell at the autoparts store just to set the new wheels on the car and take a look. Threads are corect but the shoulder on the nut is too small - fits sloppy in the wheel. Guess I'll have to wait till tomorrow to get the right lug nuts. These are Scion wheels and I understand that the stock Scion lug nuts will work. Thanks everyone for your responses......
