This really doesnt sound like a tire error or mounting error. This sounds more like the whole in the drive cups that the pin to drive your hexs is bigger now. If the whole is bigger than the pin it will allow a wobble and you will need new drive cups to have the pin be the same size.

why does it do this..annoys the heck out of me.
and i even do the electric tape trick where i wrap tape around the tires so that its constantly giving pressure while i glue...sorta like the rubberband trick.
do you think the pressure might have cuased the foam to shift...but the other 3 tires i glued is fine with the same method...something i dont know?

its not that i checked that already, i thought the same thing haha. if i mounted one of the other tires on that same axle, itll spin straight so i know its because the other tire is unbalanced or what not.

well i guess make sure your foam and tape is centered the best you possibly can get it. Also make sure your caster and camber is set right, this could cause bad tracking too. Do you use the same rims each time. maybe your rims are out of wack.

nah i have new rims each and every time.

You could try getting that spray adhesive and after you tape the tires spray some in there then spray some on the foams and put the foams in. This will definitely hold the foams in place and will not add any weight. I am thinking maybe the foams move because they will slide on tape and plastic rims but not on bare rubber so this may be the problem. :neutral:

With Heli blades there is two different things to balance. 1 is the weight of the blade and 2 is where the weight is compared to the short axis of the blade. I think maybe they are called Static and Dynamic balance?? IMO with tires and wheels the balance weight should be as close to the depth of the hex hole in wheel as possible.

sounds right, but not the case in my case. it was unbalanced right after i glued them already. the 3 perfect tires after runs and runs is still balanced so i dont think the foams shift inside. the one bad unbalanced tire maybe the foam just shifted slightly as i was applying glue was what happened.

bruce750, i just took a look at my wheels with the metal hex inside the rim, and it is heavier on one side. its heavier on the side with the spokes...which is the outside. but how am i gonna even out the wieght. i can shift the foam more towards the outside, but then it would just be not centered inside the tire then, and i could do the same withthe taping but same outcome...
