Jimmy,

Notes about measuring wheels & offsets:

·        The offset of a wheel is the distance from its hub mounting surface
to the centerline of the wheel. The offset can be one of three types

o    Zero Offset:  The hub mounting surface is even with the centerline of
the wheel.

o    Positive:  The hub mounting surface is toward the front or wheel side
of the wheel. Positive offset wheels are generally found on front wheel
drive cars and newer rear drive cars.

o    Negative:  The hub mounting surface is toward the back or brake side of
the wheels centerline. "Deep dish" wheels are typically a negative offset.



Here are my notes about my wheels & tires:

Corveric tires:  215/45 R17 91V Hankook

Wheels.  7" x 17" Ion 625. Zero offset.  Actual 4" from outside of wheel to
mating surface.  The wheels are actually 7-15/16" outside width.

This leaves 3/4" gap between fender and tire at ride height.  As the
suspension extends, there is less than 1/8" clearance as the tire clears the
fender.

Measure carefully to avoid problems!

There is a lot of space in the front, but the rear just barely clears the
fender.  Any size larger would catch the fender as the suspension is
compressed.  I believe that you WILL NOT fit 8" Wheels on your rears
successfully.  They may fit on while the suspension is hanging, but it will
crush the fender as you lower the truck onto it and it will tear the fender
on the way back.  If you have a negative offset that allows the tire to move
inwards, then the 8" wheel may fit, but it will need to move at least that
½".



I hope this helps.

My guess - and it's a guess based on just looking at the GB - is that the
fronts will fit but the rears won't.



I wouldn't buy them without a test fit.
