15x10" 5x4" bolt Steel wheels

Will 15x10 Steel wheels fit in 65 barracuda? Rims are 5.5 back spaceing. My springs are in stock location for now but just starting mini tubing. My two concerns are tire clearing outer wheel opening, and rim clearing leaf springs. Im running cragars now that are 14x8 in back with i think 4.25 backspaceing. Widest tire i had in stock wheel well was 245 60 14s. Not sure what size to run on 15x10s yet 255 50s. Anyone running 15x10s with 5.5backspaceing?


I have some SBP 15X8 Ansen slots that have a 5" BS and no problems on a 61 lancer wagon.
