I'm installing fender flares onto my 1967 ford mustang. The flares are 3 1/4in. I was wondering what tire size I should use with them so that there is enough room but also fulls much of the area as well. And i would like to get some rims that are bigger with less tire, but i still want it to have that hot-rod look. Any help on what size to get for the tires and rims would much appreciated.
