there is the link to the rims let me know

 

actually it says -38 mm offset

 

The width if the rim is going to be 10". The backspacing, which is 4" means the distance from the mounting surface to the edge of the rim on the back side. The more backspacing you have, the more the rim/tire will sink into the wheel well. The less you have the more it will stick out. Say a rim with 2" of back spacing, with 10" overal width, will stick out 8", meaning that there will be ALOT of tire/rim sticking out of the wheel well. 4" is good, since most of the stock rims are 4.5". Im not sure what the -32MM offset means. They look good.

 

Backspacing is the distance from the "inside edge" of the wheel to the wheel mounting surface. Offset is the difference between the centerline of the wheel and the wheel mounting surface.
