onemean66stang

i plan on using 15x7 in steel wheels on my 66 mustang. these rims have 4.5 in of backspacing. when i put the rims on the back of my stang it doesn't look i have enough room for a decent size tire. i was plannin on a 225/70/r15 in the rear and mickey thompson sportsman 26x7.50 front tires to give me a big and little look. what size tires should i run to achieve my my big and little setup? this car is my every other day driver so the tires need to me streetable.

4.5 bs on a 15x7 rim is too much back spacing.
