i was thinking of getting new rims for my 99 cherokee sport. just bought new tires the other day wanted to get rid of the old rusty rims. the tires are 225/75/15. would the rim size i need to get be 15X8? might purchase online so i wanted to make sure the ones i got would work with the tires i just purchased. any help would be appreciated. also, any advice on who makes nice black rims?
