simple wheel tuck/turning question

[matthufham]

i'm wondering if my rims tuck into the fenders, will i be able to turn the wheel with full clearance?

i have 2.5 inch spindles and cut a coil for about 4.5 inch of drop

i'm running little 15's right now but i'm getting 20's and wonder if i'll be able to drive it...
wheels/tires: 20x8.5 5.25" backspacing 255/35-20

i've never experienced a lowered truck tucking rims before and i'm wondering about clearance

Not sure about a static drop. I have 2.5" spindles and bags and cannot turn my wheel at all when aired out. but, when i air it up about an inch or so, i have a pretty good turning radius and still tuck tire.

i'm also on 15" wheels with about a 70 series tire.
