Balancing wheels: Weights inside or out
Just for the record - the entire Nitrogen thing is total BS.
Air is about 78% Nitrogen. Pure Nitrogen is only 22% more N2, hardly night and day.
Nitrogen expands and contracts just like air, because its what AIR IS MOSTLY. Its a gas, it follows gas laws, etc.
As for balancing...yeah, dynamic road force is the way to go. The shop I use can balance the biggest boggers every time, never a return for rebalancing. (Hunter, same machine..)
A good shop knows all the tricks, for example...there's a heavy side on every tire, and a heavy side on every rim....a good shop makes sure that these spots are 180 degrees apart, etc...to cancel out as much of the imbalance to start with, before a single weight is added.
And yep - if you're aired down (w/o bead locks...) you CAN spin a tire on the rim, screwing up your balance. Hell, dried mud, rocks, etc, can get into stuff, a lug can get ripped off, a nail can get imbedded, etc, and "rebalance" the tires too.
So - weights should be added inside and outside on a road force machine for dynamic 3 dimensional balancing. I take a sharpie, and mark the outlines of the weights...so if one gets MIA, I can tell.

Fact: Goodyear gives the teams tires with air in them, but the first thing the tire specialists do is let the air out and replace it with nitrogen. Why? Well, compressed nitrogen has less moisture in it than compressed air.
When the tire heats up, the moisture inside it will vaporize and expand, increasing the tire pressure. By using nitrogen instead of air, we have more control over how much the pressure will build when the tires heat up.
We also use nitrogen to power the air guns for pit stops, for the same reason. Those guns are expensive tools, and the moisture in compressed air would damage them.
For what it's worth, I have the bead system in my tires ($15 per tire) and I haven't had a single issue with them. I am running Micky T's 33 on my super duty.
The reason I went with the internal system was for several reasons. The main one being my weights kept falling off and I had tried both types of weights the clamp on and the stickies. Another reason I did it was I had a horrible death wobble and no one could figure it out, I knew of internal bead weights and I had them do that since everyone else was at a loss. BAM!!! Death Wobble gone. I had gone to several tire shops and had them check the balancing of all my tires and it always should balanced (except when the weights fell off of course
)
Now my tires wear evenly and look great and my rims look nice and clean not having lead weights hanging off of them.
Hope this helps someone.

Go to a tire shop that has a Hunter GPS9700 Road Force Balancer. .... If you go to Hunter's website and navagate to the GPS9700 machine you can do a search by zip code to find a shop near you who uses one. My shop only charged me $20 total! Usually they charge $10 per tire/wheel. Good luck.
