Front and back?
Staggared fitment?
Cant sec a tire unless you know the width and offset of the rim...
Not a fortune teller here.....
No ESP on my part....

275/25.4x.30x2+20x3.14=83.19763

63360/83.19763=761.5 revs per mile
those tires are smaller than OEM, thats
why the gap is so big round the fenderwells...

Your math is incorrect?

275/35 20s are actually larger in diameter than stock (.35 not .30)

275/25.4x.35x2+20x3.14=86.64117

63360/86.64117=731.2 revs per mile

To the original poster, my Roush rear springs only dropped the rear of my car approx. .8 in, but it looks much better now.
