Hello BOBSDART, Have a 1966 valiant and would like to also put 255/60/15 tires on my car but the rims I am looking at are 15 x 8 / 4.50 backing and 0 mm offset. Would these work ? I have 15x8 /3.75 backing and -18.80 /-19 .20 mm offset and they will not work stick out past fender well . I would appreciate your advice very much . Thank you Richie
