i wanna get MB wheels weapon 18x9 +15mm with 265 tire width for the rear but i'm not sure if i should get a 18x9+15mm or 18x8 +15 or +30 something mm with 165 tire width also. My goal for the car is lightness so, i'm not sure if 1 inch wider rim will give me more weights.

what are your opinion guys?
