I have a 99 Disco II, my vehicle has 18" rims which I suppose is due to the performance package? Anyway I want to get some black rims, the only ones I have found are 16". I have been fishing around the forum and I see alot of you use a 16" Bridgestone I believe, my question is if I put 16" on my vehicle will it have any negative effect on my ride? Are the 18" wheels just for looks or does it have a purpose? I figured there would be some price difference on the 16's tires that could be enough to justify getting the black rims I want since my tires need to be changed. thanks for your help.
