Just installed my new front wheels and tires. New wheels are 8 inch wide 17 inch. Old wheels were 7 inch wide 17 inch. 4inch back space, 5.48 backspace. Went from a 21550R17 tire to a 22550R17 tire. Cant believe the difference in the clearance, that 8 inch back space wheel is perfect for the front of my Dart!
