Yes they can, but with some modifications. You need to install extended front spindles (or have the stock ones professionally extended - Specialty welding/ Fab shop). You will likely need to remove your inner fender liners and roll your fenders and trim your bumpers. You don't need to lift your magnum!! they make 275/25/26 and 255/30/26 tires now specifically for these cars. I know it can be done since my magnum is lowered 2" on 26" wheels (wouldn't recommend the extra work to lower on 26" wheels) . Hope this helps :)
