Drag radials on stock 14 x 6 rims

I've installed 275x60r15's tucked in a 73 Duster. will clear with the correct backspacing on the rims. 14x6 rim won't have the correct backspacing to clear. I had 15x7 with 4" back spacing and had to roll the quarter lip. The 14" slicks will need the correct rim and back spacing. With that being said, if you're gonna lower the stance of the car and try to tuck that much tire, its not gonna clear. The stock wheel tubs tapper as you go up towards the top. The Quick Times are street legal, but don't try to drive them in the rain, plus the little slits that are cut into them that makes them streetable will cost you. I've seen these things hold water after driving thru a water box, causing the car to break out.
