It's a combination, but given the same rims, the diameter is the first
problem you will encounter. The larger diameter will allow the tires to rub
on the springs, but this is corrected by setting the steering stops out a
few turns. If the steerign stops fall out, then you get longer ones and set
them where needed to prevent rubbing.

The turning radius should not be affected so much that it becomes a problem.
I run my LockRight lockers with 32s, and I haven't ever sheared a pin. I
also run the 4.10 gears that you have, but I have the NP435 trans instead of
the NV4500. My first gear is 6.69:1, which is close to what you have, but I
only get 4 gears, where you get 5.

I am not sure the 12.50s are a good thing, or a necessary thing, but that is
more of a personal choice as opposed to a problem from a mechanical
perspective. I run the 32 x 11.50s.
