i currently have 30" Dynapro m/t's and there really deep thread disene and
i like them allot but i recently cut out my wheel wells and am planning on getting
a set of interco LTB 34X10.50-16LT  what do you guys think? i also have 2" wheel spacers

oh i should also add i have a 3" suspension lift and a 1" body lift w/ wheel wells cut out quite a bit.

It's going to be tight, figure you are going to need an additional 2" of clearance for the larger tires over what you have now.  What is the distance from your tire to fender at it's closest point?

im pretty sure when i measured i check from center of the hub to the fender was 19" and the radius of a 34" is 17.04"
but the only problem i was thinking is when turned and hit a bump or when i turn i don't know how much extra room i have worst case is ill have to add another body lift from 1-3" but i cut the fenders quite a bit because i don't like body lifts.
