Sooooo, I decided to try out the airsoft BBs in my 33x12.50 MTR Kevlars because they had to use a lot of lead weights to get them to balance right. I've read a lot of good experiences with the airsoft BBs so I went for it.

I used 8oz per tire according to the dyna bead website and now I'm wobbling all over the place.

I'm running spidertrax wheel spacers and steel rock crawler rims. I'm wondering if I should break the bead again and add a couple more ounces to the tires but don't know if that will fix the problem or not.

I'm running 30psi right now, I might play with some different pressures to see if that changes anything.

Any thoughts or ideas?

I bought the dynabeads for my 33x11.5s and love them. Very smooth and good, even wear

I'm just replying to let you know they can work, not so much to offer advice.

Have you ruled out any mechanical issues?
 
Before the beads it drove straight down the road. After the beads the steering wheel is wobbling back and forth around 40-45mph. When I get to about 50-60mph I can feel the rear and the whole jeep vibrating pretty bad.

I went up to 35psi and it helped a little bit but its still wobbly.
 
On my 36" Bias ply Iroks I used like half of the big box of airsoft bb's. Way overkill but it worked fine.
 
How much weight did you pull off? Was it a ton on one side of the wheell and not too much anywhere else? You might break the bead and spin the tire 180* on the wheel if so. Was fixaflat or slime ever used in the assembly? Just a few thoughts. My airsoft beads worked incredibly well...
 
Well, I decided to add 2 more ounces of beads. I got one more tire to go so hopefully that will do the trick!

Ill report back later, thanks guys!
 
Are you confident there is ZERO moisture in the tires? Wet bb's stick sometimes and will freeze.
 
After adding two more ounces its deffinitley better but I'm still getting some vibes.

I wouldn't doubt that there is a smidgen of moisture in there but couldn't be too much.

Should I add a couple more ounces and see what happens?
I'm not looking forward to the tire rodeo again and would like this to be my final ride :D
 
Plastic, did you guys weigh your BBs out or just throw a bunch in there?

2oz made a good difference, wondering if I should bump it 2oz untill I find the sweet spot.
 
I used the plastic ones and had zero issues with except, beyond the fact that after a few years I still find them on the floor.

All I did for measuring was get 2 large containers (I think 5000 count) of the semi-tanslucent green bb's from walmart and put half of a container (estimated by pouring) into each tire.

I had zero vibes and had no issues driving down the interstate at 80mph. That was with IROK 36x13.5 R15 superswapers on 15x8 steelies.

coolest thing about it, when I came to stops with the doors off I could actually hear the bb's rolling around in the tires.

thats the mexican in you coming out.....thems red neck maraca's
 
I thought it was more like a soothing nature sounds tape to help me relax, think whale song and ocean waves
 
I didn't want to use any metal BB's and went with plastic ones. I've seen the insides of a set of wheels that had the metal BB's and they remove the paint from the rims over time, and yeah, they are quite a bit noisy-er than the plastics.

Mexican maracas.......... LOL! :laugh:

I used 11 oz. in my 35's and I'm thinking of adding a few more ounces.
 
I'm at 14oz now and I'm still wobbling all over the place at anything over 40-45mph.
Keep in mind when I had the giant row of lead on the wheels there were no wobbles.

Do I give up and go back to lead or keep adding BBs? I'm at almost double of what dyna beads chart suggests.

I really want the BBs to work, I've got some people I'm trying to prove wrong here :D
 
Well, it woulda helped your experimentation if you had looked at the actual combined weight of the row of lead you removed. It's very possible you had more than 14oz on there.

A few years back, when that AutoBayz place was in business, I took a set of 33" MTRs and some Canyon wheels there to mount and balance them myself. I had two tire/wheel combinations that I simply could not balance - I had well over 18 oz of weights put on 'em. So I removed the weights, busted the beads, rotated the tires 180* and re-balanced. I was able to get them to balance with less than 10 oz of weight. Oddly though, the other two tire/wheels only needed a few ounces to balance. :dunno:

But again, experienced tire guys at a good shop will have a bubble balancer available and they'll put the bare wheel on that and mark the heavy side, then put the tire on and mark the heavy side, and then rotate the tire on the rim so that the heavy sides are opposite of each other and THEN balance the tire/wheel combo, thus, reducing the overall amount of weight needed to even it out.

Many tires when new, come with a colored sticker on the sidewall where the factory has already done the work to mark the heavy side. A wheel guy once told me that many wheel manufacturers don't machine the valve stem hole on a wheel until the final part of the process so that they're removing material from the heavy side of the wheel........ dunno how much of that is actually true, but I've definitely heard that on more than one occasion........ :dunno:
