tires wobbling bad... what to do? - 11.08.2007, 09:04 PM

Hey guys, I am sure lot's of you already know this sad fact... but after a while, you notice how your tires wobble bad? Like skew wobble, and un-balanced wobble... this frustrates me greatly! My badlands do this bad, and, just recently, my other RD Logics (which i love) spike tires are suddenly doing it too! Go ahead and check your model for this, you will really see it when you hold your truck off the ground and apply throttle... ARRRRRGG! It shakes the living crap out of the whole truck, which CAN'T be good for things, OR performance/handling.

Is there anything I can do to fix this? Are there any tires/foams that don't do this? Or is there a certain trick that has to be applied when glueing tires?

I hope this becomes a good resource for tire performance... after all, they ARE where the power meets road!

Are your tires taped on the inside or are you cutting the foams before you mount your tire?

Well you first have to determine whether they are unbalanced, bent, or both. If it does it the whole time the you need to check other things. You should remove your rear hub carrier with the axle still in it and tire mounted to it. Hold the hub in your hand allowing the tire to spin freely, and spin it. When the tire comes to rest add some playdoh, clay, or hotglue to the inside of the wheel at the top (because the heavy side is at the bottom, that's why the tire came rest the way it did). Spin again and add or remove the weight, this should only take 3-4 spins to get the tire/wheel balanced, any more and you're being picky. Then remove the tire and repeat to your other 3.
Another thing to observe while you're spinning tires is the trueness of the spin, you shouldn't be able to see any wobble or wiggle side to side. If you do, look for cracks in your wheel, especially around the hex. If it's just warped you may be able to bend them back a little, but it's ussually just a temporary fix.

Basically what Matthew_Armeni is saying, is to balance your tires/wheels. This is a common thing for racers to do, as it decreases unpredictability in the truck's handling, and will allow the power to be put down smoother.

Guys I work with buy airplane prop balancers and mod them to use them as car/truck tire balancers. I'm pretty sure they use this one:

but I'm not sure what they do to make car/truck wheels fit on there.

Thanks guys.... although, I think I may have found ONE problem here for the badlands wobbling.

The tire that was on that 23mm adapter wobbled considerably more than the others. Also, I seems like when I first put the tire on say tire 'X', then held that one so it wouldn't spin (to check another tire for balance), then went back to tire 'X', it would start wobbling, which leads me to believe that I 'distrurbed' the foam insert in the tire, that's the only thing I can think of.

Anyways, I checked out each 23mm hex adapter one by one (pro-line brand, btw) on the same tire, and to my discovery, most of the wobbling was because of the adapters, each one had varying degrees of wobble. One of them, has perfect alignment. I think I should go pick me up some Dace adapter then.
