im planning on upgrading my stock 15 inch magwheels. Im not really particular with the brand as long as it is a decent brand. All im looking for is for the color to be black. is it a waste if i just stick with 15 inches since i want to still use the tires that came with the car. is there a benefit to getting larger mags like 16 or 18 inches?

please give your recommendations.

Thanks!
