We just tried this on my 42' tsl's and it helped at 45mph and up but at low speeds like taking off from a stop light it made it much worse. We used 12oz per tire of air soft .25 high impact pellets. After reading this thread I had high hopes but results may very.

i notice the balancing to kick in at about 15mph, i had horrible death wobble before even with the wheel weights and it was loose shackles and no stabilizer. were your tires balanced before or brand new? i just went back and looked at the chart and 12oz is right except if you are running a 16" rim its 10oz for some reason. on suggestion i can think of is checking your steering just in case something is loose, add a stabilizer if you dont have one and check your front shackles. you might even need to take out or add bbs. hope that helped a little and good luck and hope it works out!

They are new and unbalanced. But I did take a tire groover to them. We checked the toe on his truck and it's out too much. I know that will cause the shimmy shimmy shake. Were gonna set the toe and balance them.

I don't think gooving them would effecting them but yet again i've never had grooved tires. hope fixing the toe helps. and what psi are you running your tires. going down about 5psi from the side ways says sometimes helps.

Well we took the BB's out and put one on the balance machine. It had flat spots so bad we would need 26oz's of weight on one side! The tires are pretty new but it looks like he let them sit flat on his rig for awhile. They weren't that bad on my 12 wide wheels but his tens were awful. So it looks like I have to keep em. My brother in law drives his truck daily. I was gonna trade them for his 42 iroks. He wanted my TSL's because they would last twice as long. Hmm looks like I need to find a way to buy some 42' rockers.

Cool.

I've been struggling with this BB balancing thing. My weirdness: 37x12.5x15 Radial Iroks. When I put them on, no weights, they were terrific up to 70mph. After MCR09 I had a shake. I was adding lead BBs to the tires until I had almost 2lbs in all the tires and that was the last time they ran okay but I got a shake at all speeds and nothing changed at different speeds, no death wobble ever. Now the fronts have 10 oz of lead BBs and they death wobble between 30-55mph. At 64 and 71mph they're good

The rear tires, I pulled out the BBs, had a tire shop look at balancing them and they need 12 and 19 oz to balance but without BBs or weights they run fine

My next thing is to try 0.20 gram airsoft BBs. 8 oz in the fronts only. I figure they are less dense and so, will spread out more. They are on order, the Ebay seller is slacking and 3 weeks after purchase I'm still waiting. They sent the wrong stuff the first time. Anyone want 500 6mm aluminum BBs?

Uh!

When was the last time you checked your caster angle?

madhunt · « **Reply #247 on:** Aug 10, 2011, 09:39:31 AM »

well a 37x12.50x15 should only take 8 oz of bb's if you look at this chart www.innovativebalancing.com/BigTirechart.htm i have used their chart before for big truck tires.

jrock · « **Reply #248 on:** Aug 10, 2011, 11:09:04 AM »

I never checked it.

MCR09 was the first time I aired down these tires. I figured something changed inside the tire. I'll try and check it tonight.

That's why I'm hesitant to add more weight. 10oz is my limit. I hear Super Swampers are a pain to balance. I know why now.

MiniSimp · « **Reply #250 on:** Aug 10, 2011, 11:20:56 AM »

I put 10oz in mine and they are good on the highway at 0psi after 15mph.

No, they had 5psi when you were going 70

oops sorry my bad

jrock · « **Reply #254 on:** Aug 10, 2011, 11:45:19 AM »

I keep these tires between 30-35psi. Anything less and they are horrible on the highway.

Iroks on 8's seem to do well (with bb's)

jrock · « **Reply #256 on:** Aug 10, 2011, 04:03:17 PM »

Thats what I thought. It makes me wonder if these tires have something wrong internally. Other than that, everything looks in order. I rebuilt the front end, new trunions and everything. Have checked alignment practally very week since this all started. Toe in 1/8-1/4" works, 0" toe in seems to be okay. Toe out 1/8" is death.

I just added hydro and the steering wheel doesn't shake anymore

but the truck still does and you can tell there is still a death wobble in the tires

jrock · « **Reply #257 on:** Aug 10, 2011, 07:01:31 PM »

My caster is 5 degrees, +/- .5

Hey guys i read all this stuff on here and I'm 99% sure I'm going to get some airsoft BB's but wanted to see what you guys think first. Before i knew that much about all this i went to a commercial tire shop to get my iroks balanced. 37 bias on 15x10 rim with 80% tread on yota axles.

They suggested to put in Counteract balancing beads, which seamed like the way to go at the time and worked a little but it sucked after the first couple trips. its like they have permanent flat spots.

I looked last night at the receipt and they put 2 10oz bags in each tire, after reading on here that is way to much i should only have 8-10oz per tire from the chart.

I guess I'm going to vacuum it out and try the Airsoft BB's and see what happend for myself.

Any input that you see helping would be great if you did this on your iroks. How it worked and how much you put in mainly, what size and how many you used..
thanks martin

i have 37 14 15 iroks bias on a 15x10 aluminum rims and i have 8oz of BBs in each tire and they seem to do well not a huge woble

jrock · « **Reply #260 on:** Oct 26, 2011, 03:12:17 PM »

If you have the BBs that the truck shop used, I'd reuse them. What are they made out of?

I ended up with 8oz in both front tires and nothing in the rears. Works great, if I wanted it better I could push the fronts up to 10oz and put 8oz in the rears. It took me a while but I found the "best" two tires and put them up front and then balanced.

86moneypit · « **Reply #261 on:** Oct 27, 2011, 08:00:33 AM »

I thought about reusing the beads but they are super small kinda like sand almost and i think they are settling in one spot because they might of got wet and there is two much in there.

What size BB's are you running?

I haven't checked yet but will they go through the valve core or do you have to pop the bead.

jrock · « **Reply #262 on:** Oct 27, 2011, 08:18:52 AM »

I used .25gram high quality airsoft BBs. I used what Big Mike used. I found them online but I later found them at Ace Hardware. They were a bit more money but there would have been no headach.

You will need to pop the bead, your going to do that to vacuum the old stuff out so no big

86moneypit · « **Reply #263 on:** Oct 27, 2011, 09:06:30 AM »

Cool sounds good.

How much of a pain is it to pop bead an reset them, I've never done it before. I saw the illustration on here but seems like might be hard to get it to reseat.

KDXSR5 · « **Reply #264 on:** Oct 27, 2011, 03:12:34 PM »

To Break Beads:

1: Pull tire/wheel off of rig

2: Throw tire/wheel on the ground under the bumper of a heavy vehicle NOT THE ONE YOU JUST PULLED THE WHEELS/TIRES OFF OF

3: Pull out high lift

4: Place foot of high lift on the tire right next to the rim and place the claw on the underside of heavy vehicle's bumper

5: Jack highlift until the bead pops off the rim. Repositioning may have to be done to get it to break

BE CAREFUL!!!

To Reseat:

1: Throw tire/rim on ground

2: Wrap a ratchet strap around the tire and tighten it tight

3: Put air in the tire

It should pop the bead onto the rim.

I have used these methods multiple times and have only had one tire I could not break the bead on. I ended up taking it to the local high school to have them use their machine to break the bead. They even had problems with it, but it was a tire that was on the same rim for probably 15 years.

jrock · « **Reply #265 on:** Oct 27, 2011, 05:33:14 PM »

Thats exactly what i have done a few dozen times, I recommend you throw something on the ground like an old rug so you don't mess up your rims. Some people care about that sort of thing

Also, make sure the jack is perfectly vertical, make sure it pushes straight down on the tire.

Be carefull setting the bead, it may take a little while if your air supply is slow. When it Pops on, it will really pop.

Thanks for all the info guys. Seems easy enough to do. I'm going to try it out this weekend if i get some spare time.

Need to get some BB's now and start to balance theses things out so my teeth stop rattling.

Those should be ceramic beads and should NOT clump together. You pretty much said it yourself, they put too much in. You should drop to the recommended weight per tire before wasting money on more beads.

Dont forget to take the air out of the tire first.
