A little wobble with bigger tires

I just put on new bigger tires and I'm having some wobble in the steering around the 40-50 mph range. I have 3" BDS springs and shocks, adjustable track bar and longer sway bar links. I do NOT have cam bolts or longer control arms. I went from 265/75/16 to 33/12.5/15's. Any suggestions on where I should start? Thanks!

First make sure tire are balanced perfectly.
Alignment (toe in and caster)?

You might want to try a dry steer test and check tie rod ends, both ends of drag link.

Also, make sure your tires are not over inflated. 33x12.5 should be 26-28psi.

When you lift a jeep, even a small amount, it will change the suspension geometry a lot. When I lifted my old wrangler 3 inches and put 33's on it, I got horrible death wobble, when before I didn't have a single thing wrong. The control arm bushings were bad, the track bar bushings were bad, the steering stabilizer was bad, all the things were brought forward with just a small change.

Start with putting it on some good jack stands and a pry bar and check for play in all the joints and bushings, in the control arms and steering. And you really have to pry around. Anything is loose, adjust or replace accordingly. The steering stabilizer should be your last bet, as a proper steering set up, in theory, doesn't need a stabilizer.

Proper tire balancing is paramount....I'm kinda bias when it comes to tires, BFG or nothing else from personal experience.
Improper alignment would sure cause steering wheel to shake a little.

you just added the tires, right? so the lift was installed before the tires and there was no vibe then

in that case, i'd suspect balance. you can rotate your tires and see if the vibe changes, or go back to the tire shop and have them check the balance. hopefully they have a hunter road force balance machine
