How's your steering stabilizer/shock?
It's good, as far as I can tell.
Where is the shimmy, bump steer, or death wobble?
If it is in the steering wheel it is the tires, usually a balance/out of round issue. The other 2 are steering issues
You cheapest route would be to have either the 30's or 33's balanced and see if that doesn't solve your problem.
Not bump steer, not DW. There is no motion transferred to the steering wheel and it doesn't pull when braking. It pulls to one side and then it'll pull to the other, when running straight. Both the 30s and 33s are balanced.
