lug nut bolts

Hey I have a 2001 nissan xterra SE and I was wondering if you guys knew what size the axle bolts for the wheels were if they were 14 mm or 12 mm Im trying to figure out so I know which size of lug nuts to get for my aftermarket rims.

Thanks

I have an 04 SE and mine are 12x1.25. I dont see why they would be different since everything else is interchangeable. But I would double check.

well I checked 3 other websites and they all said 12x1.25 too so I ordered 12x1.5 and just got them today and tried them and they wouldnt thread in so I compared the size and the stock ones look like 14's.
