I have a 1957 chevy belair. I have american racing 15 x7 wheels with a minus 6mm wheel offset. I would like to use some BF Goodrich Radial ta. But they come in the 215 X 70 size. Will this size fit the 1547 belair or must I stay with 205 70 15. Can you recommend any type of tire that you sell that will fit my needs?
