tire wheel pics please !!!!

255/60-15s on the back of my '69. Rims are 15x7 with 4 1/4" backspace. They will fit with about 1/2 - 3/4" clearance all around and they will rub just a little on the inner wheelhousing on my 'vert if I am making a turn uphill. It could be because of the springs on the car.
