HELP Please (pics attached)

you most likely have the 4.5" wide wheel-- look for some 5.5" wide ones or put an ad out for custom made widths. there are shops that will make them to size-- jegs has a sale on 15x7 & other sizes now but only in 4" backspace,

there is a thread showing some interesting wheel tire combos on the darts-- i believe one member has 275/60/15 under his with no mods.
