Does anyone know the offset of theOEM 16x7 rims? I can buy a set of 22x10 with an offset of 50mm ( so backspacing of about 7 inch). I would like to find out if I can fit these without spacers. If I measure right ther is about 8 inches of room between the mounting plate and the shock, so I think that if I'll mount 285 tires that won't bulge out of the rim much it could work.
