I added 10 oz. of .25 gr 6mm "ultra heavy" airsoft BB's to my 37" Interco SS M16. They run great until I reach 60 mph, after that, things get pretty sketchy. Before I added the BB's, I would get a hop from the tires using tape weights at 60+. Now with the BB's, I get a strong wobble or shake from the front end. Any suggestions?

 

Add more pellets. Basically you can add too few but you cant add too many. I am going to add 2 more oz to each tire at some point. Mine have a slight shimmy at 80 mph. Good up until there

 

I have 10.5 oz of airsoft in my 37 Goodyear mtrk on raceline beadlocks and they work awesome! People recommend putting a shot glass size of antifreeze in with it because air has water in it and could cause freezing and clumping without it.

 

Thanks, will give it a try. Any more info on the anti-freeze suggestion? I was wondering about the BB's clumping inside the tire.

 

Antifreeze is not necessary for me but I live at the beach in a cold Climate I can see it being useful

 

This may be stupid. If I use dyna beads or some other similar product, I never have to have my wheels balanced at the mechanic?

 

After reading endless forum posts, I just used 8oz of air soft bb's today in my 315/75/16 Duratracs. I get them put on the jk tomorrow. I will keep everyone posted.

Another? What is the easiest way to add more if needed. Do I have to remove the tire and break the bead again?

 

No dumb questions. That is the theory, no need for weights and continuos on the fly balancing as tires wear.

 

If you need to add that is the only way I know of.

 

I have 35s... took to shop for routine alignment and balancing..had nice smooth ride at all speeds before...
They took off balance weights and installed Dyna beads....now horrible...at about 40 mph shake...starts to go away between 50 to 64 mph...then starts again to where front end especially jumps around so bad can't drive safe above 65...taking it back in tomorrow to get rechecked and balanced...
