Dart seems tighter than a duster/dart sport and the best I could do with about 1/3-1/2" of clearance was a 215/65r/15 on my duster which is 26" tall. This on a 15x6" Cragar 5 spoke with about 3 3/8" backspacing and narrower than the cop wheels. To the OP, height is the main issue and you should listen to bluNblu here.
