Chad...
I tried balancing 3 sets of 37's with BB's with mixed results.
The first set were Toyo's. They are pretty round as you know and don't require a ton of weight anyway. I used way too much with two shot glasses of BB's for them. Had slight vibes.
next were the MT/R's. Notorious for being hard to balance and not really round, vibes again with 2 shot glasses.
Then the iroks. Holy crap, biggest POS tire I had the pleasure to try and balance. Tried 1 shot glass, 2 and then 3.
It got worse before better. I am thinking the reasoning above is pretty accurate. I always though the extra weight would just go inert and not affect the tire balance. I think that line of thinking is wrong, more weight will affect the tire drastically.
really, start with the smallest amount you can with the golf balls. I would put 2 in. seriously. Then drive it. I know it's a pain, but if you want the help I will give a hand doing this. I have the tools and rigs to break one bead off to drop more in.
Also...just to rub it in...
My Creepy Crawlers on the TR beadlocks?
no balancing, perfect at 70 MPH.

Best tire balance wise I've owned...and I think I have owned most all tires.
