What is the true measurement width of these rims (17x10). Are they true ten inches wide or ten and a half. I want to put the nitro nt555 315/35/17 tires on them but not sure if they will fit properly. I have the stock 16x7's on the front with a 245/50/16 and know that tire should be on a wider rim too. Will the tires fit and what is the true measurement of the rim. If I order the, together will they arrive at my house mounted and balanced like a wheel and tire kit( would be getting two of each)??
